Question 1Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

Under Part-66, which category of aircraft maintenance licence permits the holder to issue certificates of release to service for an aircraft following scheduled line maintenance and to certify maintenance carried out on aircraft structures?

  1. Category B2
  2. Category C
  3. Category B3
  4. Category B1 Correct answer.

Explanation

Part-66 B1 is the mechanical licence covering airframe, engine and electrical systems, and it includes certification of structural maintenance tasks within its scope. The other categories cover avionics, light non-pressurised aeroplanes or base maintenance management rather than mechanical line certification.

Question 2Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

For a Part-66 Category B1.1 licence, what is the standard basic experience requirement before applying for the licence (without any reduction)?

  1. Five years of practical maintenance experience
  2. Three years of practical maintenance experience Correct answer.
  3. One year of practical maintenance experience
  4. Two years of practical maintenance experience

Explanation

Part-66 sets the basic experience for a full B1 or B2 licence at three years of practical maintenance experience on operating aircraft, unless a reduction applies through approved basic training. Shorter periods apply only to limited categories such as B3 or where Part-147 training gives credit.

Question 3Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

A certifying staff member holds a Part-66 licence issued by one EASA member state. Under the mutual recognition principle, what is the position when working in another member state?

  1. The licence is valid only for training purposes until converted
  2. The licence is recognised, subject to national notification and any limitations recorded Correct answer.
  3. The licence must be re-issued by the new state before any certification
  4. The licence holder must hold a second licence from the host state

Explanation

Part-66 licences are mutually recognised across member states, so a holder may exercise certification privileges in another state subject to notification requirements and any limitations. Re-issue or a second national licence is not required.

Question 4Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

In Part-145, what does the accountable manager's responsibility for the maintenance organisation primarily cover?

  1. Holding the Part-66 licence for every category employed
  2. Approving each individual work order before release
  3. Personally performing all certification tasks
  4. Ensuring that all maintenance is funded and carried out to the required standard Correct answer.

Explanation

The accountable manager has corporate authority to ensure that all maintenance activities can be financed and carried out to the standard required by Part-145. This is a management and resourcing responsibility rather than a hands-on certification duty.

Question 5Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

Which document issued by a Part-145 organisation authorises a named individual to certify maintenance and identifies the scope of that authorisation?

  1. The airworthiness review certificate
  2. The maintenance organisation exposition
  3. The certificate of release to service
  4. The company authorisation (certifying staff authorisation) Correct answer.

Explanation

Part-145 requires the organisation to issue a company authorisation to certifying staff, defining the scope and limits of the certification privileges granted. The exposition describes procedures, but the individual authorisation is what empowers the person to certify.

Question 6Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

Under Part-M, which person or organisation is ultimately responsible for the continuing airworthiness of an aircraft operated for non-commercial purposes by a private owner?

  1. The owner or operator, unless contracted to a CAMO Correct answer.
  2. The Part-145 maintenance organisation
  3. The pilot in command
  4. The competent authority of the register

Explanation

Part-M places continuing airworthiness responsibility on the owner or operator, who may contract this to a continuing airworthiness management organisation where the rules allow. The maintenance organisation only performs the work it is contracted to do.

Question 7Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

What is the primary purpose of an airworthiness review under Part-M?

  1. To confirm that the aircraft, its records and its maintenance status comply with continuing airworthiness requirements Correct answer.
  2. To renew the aircraft insurance policy
  3. To authorise the installation of a new engine type
  4. To certify the aircraft for a specific commercial route

Explanation

An airworthiness review is a systematic check that the aircraft and its continuing airworthiness records meet the applicable requirements, leading to issue or renewal of the airworthiness review certificate. It is not a commercial or insurance process.

Question 8Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

A privately operated aeroplane under Part-M has accumulated a defect that affects airworthiness. Which document records the deferral of that defect and the conditions under which the aircraft may continue to be operated?

  1. The technical log with a deferred defect entry referencing the applicable MEL or approved deferral procedure Correct answer.
  2. The maintenance organisation exposition
  3. The aircraft flight manual only
  4. The weight and balance report

Explanation

Deferred defects are recorded in the technical log with reference to the applicable minimum equipment list or approved deferral procedure, including any operational conditions. This gives a controlled basis for continued operation and later rectification.

Question 9Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

What is the role of a Part-147 approved maintenance training organisation?

  1. It performs airworthiness reviews on behalf of the competent authority
  2. It issues Part-66 licences directly to candidates
  3. It provides approved basic and type training that can be credited towards Part-66 licence requirements Correct answer.
  4. It issues certificates of release to service for commercial air transport

Explanation

Part-147 organisations deliver approved basic training and type training, and successful completion gives credit towards the knowledge and experience requirements for a Part-66 licence. Licensing itself remains with the competent authority.

Question 10Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

Under Part-66, which of the following is required to maintain the validity of a licence holder's certification privileges in relation to recent experience?

  1. Six months of relevant maintenance experience within the preceding two years Correct answer.
  2. Continuous employment with a single Part-145 organisation
  3. Annual attendance at a Part-147 course
  4. A minimum number of certification events recorded each month

Explanation

Part-66 requires recent maintenance experience, typically six months of relevant work within the preceding two-year period, to keep certification privileges valid. This ensures currency of practical skill and knowledge.

Question 11Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

In a Part-145 organisation, what is the significance of the maintenance organisation exposition (MOE)?

  1. It documents the organisation's procedures, scope of approval and means of compliance with Part-145 Correct answer.
  2. It replaces the need for individual certifying staff authorisations
  3. It is the aircraft technical log for each maintained aircraft
  4. It is a commercial brochure describing services to customers

Explanation

The MOE sets out the organisation's scope of work, procedures and how it complies with Part-145, and the organisation must operate in accordance with it. It is the primary compliance document for the approved organisation.

Question 12Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

A Part-145 organisation wishes to subcontract a major component repair to another organisation. What is the requirement regarding the subcontracted organisation?

  1. It must be owned by the contracting organisation
  2. It must always hold a Part-66 licence
  3. It must be approved to an equivalent standard acceptable to the competent authority, unless a specific exemption applies Correct answer.
  4. It must be located in the same member state as the contracting organisation

Explanation

Part-145 allows subcontracting only to organisations approved to an equivalent standard acceptable to the competent authority, with the work controlled through procedures and contracts. Ownership or geographic proximity is not the criterion.

Question 13Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

Which of the following best describes the purpose of the certificate of release to service (CRS) issued under Part-M or Part-145?

  1. It records the fuel uplift for the flight
  2. It certifies that the maintenance has been completed satisfactorily and the aircraft is airworthy for the intended operation Correct answer.
  3. It certifies that the aircraft is insured for the intended flight
  4. It authorises the pilot to fly without further checks

Explanation

The CRS confirms that the required maintenance has been carried out and that the aircraft is considered airworthy for the intended operation, subject to any recorded limitations. It is the formal statement enabling return to service after maintenance.

Question 14Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

Under Part-M, when must an aircraft operator arrange an airworthiness review?

  1. Only after a major modification
  2. At intervals not exceeding one year, to allow renewal of the airworthiness review certificate Correct answer.
  3. Before every commercial flight
  4. Every five years regardless of operation

Explanation

The airworthiness review certificate is valid for one year and is renewed following an airworthiness review, so reviews are arranged at intervals not exceeding one year. Other triggers such as modifications may require additional assessment but do not replace this periodic cycle.

Question 15Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

A mechanic holds a Part-66 B1 licence but has not worked on the specific aircraft type for three years. What does this affect?

  1. The need to renew the licence through a Part-147 examination
  2. The recent experience requirement needed to exercise certification privileges on that type Correct answer.
  3. The validity of the licence itself, which automatically lapses
  4. The mechanic's eligibility to hold any category of licence

Explanation

Licence validity and certification privileges depend on maintaining recent relevant experience; a long gap means the person may not exercise privileges until currency is restored. The licence itself does not automatically lapse solely because of the gap.

Question 16Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

In the context of Part-145, what is the function of the quality system?

  1. To issue type certificates for aircraft
  2. To replace the need for competent authority oversight
  3. To monitor compliance with the approved procedures and to feed back corrective actions Correct answer.
  4. To set the commercial price of maintenance work

Explanation

The Part-145 quality system monitors that maintenance and procedures comply with the approved standards and that corrective actions are taken where deficiencies are found. It supports, but does not replace, competent authority oversight.

Question 17Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

A Part-66 applicant has completed approved basic training at a Part-147 organisation. How does this affect the experience requirement for the licence?

  1. It removes any need for practical experience
  2. It may allow a reduction in the required practical experience in accordance with Part-66 Correct answer.
  3. It only affects the type rating, not the basic licence
  4. It automatically grants the licence without further assessment

Explanation

Part-66 provides for a reduction in the practical experience requirement where the applicant has completed approved basic training, reflecting the structured knowledge already gained. Practical experience is still required, but the period may be shortened.

Question 18Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

Under Part-M, which of the following is the correct action when an aircraft is found to have a serious defect during maintenance that cannot be rectified before the next flight?

  1. Allow the pilot to decide whether to accept the defect
  2. Record the defect only in the maintenance organisation's internal files
  3. Release the aircraft with a note in the technical log and no operational restriction
  4. Withhold the certificate of release to service until the defect is rectified or properly deferred in accordance with approved procedures Correct answer.

Explanation

A CRS may only be issued when the required maintenance has been completed and the aircraft is airworthy; a serious defect that cannot be rectified or properly deferred prevents release. The defect must be controlled and recorded through the approved procedures.

Question 19Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

Which statement correctly describes the relationship between Part-M and Part-145?

  1. Part-M covers continuing airworthiness management and Part-145 covers maintenance organisation approval for commercial air transport Correct answer.
  2. Part-145 covers only pilot licensing
  3. Part-M replaces Part-145 for all maintenance
  4. Part-M applies only to private aircraft and Part-145 only to military aircraft

Explanation

Part-M addresses continuing airworthiness management and maintenance requirements, while Part-145 sets the approval standard for organisations performing maintenance, particularly for commercial air transport. They operate together rather than one replacing the other.

Question 20Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

A Part-145 organisation employs certifying staff. What must be verified before a person is granted a company authorisation to certify?

  1. That the person has never worked for another organisation
  2. That the person has at least ten years of experience
  3. That the person holds an appropriate Part-66 licence or meets the alternative qualification requirements, and has the relevant type knowledge Correct answer.
  4. That the person is a shareholder in the organisation

Explanation

Company authorisation requires that the individual holds the appropriate Part-66 licence or otherwise meets the qualification requirements, and demonstrates the relevant type and task knowledge. Experience and employment history are assessed against the applicable criteria, not arbitrary thresholds.

Question 21Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

Which of the following is a continuing airworthiness management task typically performed under Part-M?

  1. Performing the actual structural repair on the aircraft
  2. Tracking and controlling airworthiness directives and their embodiment Correct answer.
  3. Certifying the aircraft's radio equipment
  4. Issuing the type certificate for the aircraft

Explanation

Continuing airworthiness management includes tracking airworthiness directives, service bulletins and maintenance due dates to ensure timely compliance. Physical repairs and equipment certification are separate maintenance tasks.

Question 22Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

What is the significance of a finding raised by a competent authority against a Part-145 organisation?

  1. It requires corrective action within an agreed timescale, and failure to respond may affect the approval Correct answer.
  2. It automatically suspends all licences held by the organisation's staff
  3. It applies only to the individual who performed the task
  4. It is an informal suggestion with no consequence

Explanation

Findings from authority oversight require the organisation to propose and implement corrective action within an agreed timescale; unresolved findings can escalate and affect the approval. The finding is addressed at organisation level, not by automatically suspending staff licences.

Question 23Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

An operator under Part-M contracts a Part-145 organisation to perform maintenance. Which statement about responsibility for the certificate of release to service is correct?

  1. The operator must always issue the CRS regardless of who performed the work
  2. The Part-145 organisation issues the CRS for the maintenance it performs, within its approval scope Correct answer.
  3. The competent authority issues the CRS after each maintenance visit
  4. The aircraft manufacturer issues the CRS

Explanation

Where maintenance is performed by a Part-145 organisation, that organisation issues the CRS for the work within the scope of its approval. The operator remains responsible for overall continuing airworthiness management.

Question 24Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

A Part-66 licence holder is asked to certify a task for which the company authorisation does not include the relevant type. What is the correct response?

  1. Decline to certify until the authorisation is extended to cover the type Correct answer.
  2. Certify the task and record the limitation in the technical log
  3. Ask a colleague to sign on the holder's behalf without any authorisation
  4. Certify the task because the Part-66 licence covers all types

Explanation

Certification privileges are limited to the scope of the company authorisation, which must cover the relevant type and task. Certifying outside that scope is not permitted, so the authorisation must be extended first.

Question 25Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

Which of the following best explains why Part-147 training must be approved and audited?

  1. To replace the competent authority's licensing function
  2. To ensure that the training content and facilities meet the standards needed for valid credit towards Part-66 Correct answer.
  3. To allow the training organisation to issue airworthiness review certificates
  4. To permit the training organisation to set its own licence examination standards without oversight

Explanation

Approval and audit of Part-147 training ensure that courses, instructors and facilities meet defined standards so that completion can be credited towards Part-66 requirements. It does not transfer licensing or airworthiness review functions to the training organisation.

Question 26Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

Under Part-66, which category of licence is intended for staff who carry out and certify line maintenance on turbine-engine aeroplanes?

  1. Category C
  2. Category B2
  3. Category A
  4. Category B1 Correct answer.

Explanation

The B1 category covers licence holders who may issue certificates of release to service after line maintenance on the airframe, engine and mechanical systems of the aircraft type endorsed. Category A is limited to minor scheduled line maintenance tasks, B2 covers avionics systems, and C is a base maintenance certification category.

Question 27Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

For a Part-66 licence, what does the term 'type rating' endorse on the licence?

  1. The holder's general category of work
  2. The specific aircraft type the holder may certify Correct answer.
  3. The holder's employer's approval number
  4. The holder's medical fitness class

Explanation

A type rating is an endorsement that authorises the licence holder to certify maintenance on a specific aircraft type, within the privileges of the licence category. It is granted after meeting the type-specific training and experience requirements for that aircraft.

Question 28Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

Under Part-M, who is responsible for ensuring that an aircraft is maintained in accordance with the maintenance programme?

  1. The competent authority of the State of registry
  2. The Part-66 certifying staff individually
  3. The Part-145 organisation only
  4. The owner or operator, as the continuing airworthiness management responsibility holder Correct answer.

Explanation

Part-M places continuing airworthiness management responsibility on the owner or operator, or on a contracted continuing airworthiness management organisation where applicable. The maintenance programme must be controlled and its tasks accomplished in accordance with that responsibility.

Question 29Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

What is the main purpose of the aircraft maintenance programme under Part-M?

  1. To list the approved parts suppliers only
  2. To describe the operator's commercial schedule
  3. To record the hours flown by each pilot
  4. To list the maintenance tasks and their intervals required to keep the aircraft airworthy Correct answer.

Explanation

The maintenance programme defines the scheduled tasks, intervals and applicable requirements needed to maintain the aircraft in an airworthy condition. It is derived from the type certificate holder's recommendations and any additional requirements, and is approved or accepted as applicable.

Question 30Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

In a Part-145 organisation, who is responsible for ensuring that the organisation complies with Part-145?

  1. The accountable manager Correct answer.
  2. The certifying staff representative
  3. The quality manager alone
  4. The competent authority

Explanation

The accountable manager has overall responsibility for ensuring that all maintenance required by the organisation can be financed and carried out to the standard required by Part-145. This responsibility cannot be delegated away, although duties may be assigned to nominated persons.

Question 31Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

Under Part-147, what is the primary purpose of an approved basic training course?

  1. To provide the theoretical and practical training that satisfies part of the Part-66 knowledge and experience requirements Correct answer.
  2. To certify aircraft after maintenance
  3. To issue Part-66 licences directly
  4. To replace the need for any practical experience

Explanation

A Part-147 approved basic training course provides structured theoretical and practical training that can be credited towards the Part-66 knowledge requirements and reduces the practical experience needed. It does not itself issue licences or certify aircraft.

Question 32Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

What does a Certificate of Release to Service (CRS) confirm when issued after maintenance?

  1. That the aircraft has been sold to a new owner
  2. That the maintenance work has been properly completed and the aircraft or component is airworthy in respect of that work Correct answer.
  3. That the maintenance programme has been approved by the authority
  4. That the pilot is current on the type

Explanation

The CRS certifies that the specified maintenance has been carried out and that the aircraft or component is airworthy in respect of the work performed. It is a key record that supports continuing airworthiness.

Question 33Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

Which document in a Part-145 organisation describes the scope of work, procedures and responsibilities of the organisation?

  1. The aircraft flight manual
  2. The minimum equipment list
  3. The maintenance organisation exposition Correct answer.
  4. The technical log

Explanation

The maintenance organisation exposition (MOE) describes the organisation's scope of approval, procedures, responsibilities and quality arrangements. It is the primary document demonstrating how the organisation complies with Part-145.

Question 34Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

A Part-145 organisation wishes to use a specialist external organisation for NDT inspections. What must the Part-145 organisation ensure before this arrangement is used?

  1. That the work is omitted from the maintenance programme
  2. That the aircraft owner signs the CRS
  3. That the external organisation holds a pilot licence
  4. That the external organisation is approved or accepted for the work and controlled through a documented contract or quality arrangement Correct answer.

Explanation

Where maintenance is subcontracted, the Part-145 organisation remains responsible and must ensure the subcontractor is appropriately approved and that the arrangement is controlled and documented. The scope of the subcontractor's approval must cover the work concerned.

Question 35Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

A Part-66 B1 licence holder has not exercised certification privileges on a type for a prolonged period. What is the standard Part-66 requirement to maintain validity of the certification privileges?

  1. Only payment of the annual licence fee
  2. Only a valid medical certificate
  3. Recent maintenance experience on the type, or completion of a relevant refresher or assessment acceptable to the competent authority Correct answer.
  4. Only membership of a professional association

Explanation

Part-66 requires recent experience relevant to the certification privileges, or an acceptable refresher or assessment, to keep those privileges valid. This ensures the holder remains familiar with the type and current practices.

Question 36Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

An aircraft operated under Part-M has a defect that affects airworthiness. Which document is used to record the defect and the subsequent maintenance action?

  1. The aircraft technical log Correct answer.
  2. The airworthiness review certificate
  3. The part-66 licence
  4. The maintenance organisation exposition

Explanation

The technical log records defects, deferred items and the maintenance actions taken, providing a continuing record of the aircraft's status. It links the operating crew's reports to the maintenance and certification process.

Question 37Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

What is an airworthiness review under Part-M intended to confirm?

  1. That the pilot has completed recurrent training
  2. That the aircraft's continuing airworthiness records and physical condition support the issue or renewal of an airworthiness review certificate Correct answer.
  3. That the aircraft has completed a commercial sale
  4. That the maintenance programme has been discontinued

Explanation

An airworthiness review is a systematic check of the aircraft's records and physical condition to confirm continuing airworthiness and to support issue or renewal of the airworthiness review certificate. It is a key continuing airworthiness control.

Question 38Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

A Part-145 organisation identifies a finding during an internal audit. What is the appropriate response?

  1. Refer the finding only to the aircraft manufacturer
  2. Delete the finding from the audit report
  3. Record the finding, determine its cause, take corrective action and verify effectiveness within a defined timescale Correct answer.
  4. Ignore the finding if no customer complaint has been received

Explanation

Findings must be recorded and managed through a corrective action process that addresses root cause and verifies effectiveness. This is part of the organisation's quality system and its obligation to maintain compliance.

Question 39Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

Under Part-M, which organisation may carry out continuing airworthiness management tasks on behalf of an operator?

  1. A Part-M Subpart G continuing airworthiness management organisation Correct answer.
  2. Any Part-145 maintenance organisation without further approval
  3. Any aircraft parts distributor
  4. Any Part-147 training organisation

Explanation

Continuing airworthiness management tasks may be performed by an organisation approved under Part-M Subpart G for that purpose. A Part-145 approval covers maintenance, not continuing airworthiness management as such.

Question 40Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

A Part-145 organisation plans to release an aircraft after base maintenance. Which condition must be satisfied for the CRS to be issued?

  1. The operator has paid the maintenance invoice
  2. All required maintenance has been completed and certified by authorised certifying staff, with any deferred items properly controlled Correct answer.
  3. The aircraft has been washed and painted
  4. The flight crew has completed a simulator session

Explanation

The CRS may be issued only when all required maintenance has been accomplished and certified by staff authorised for the task, and any deferred items are controlled in accordance with approved procedures. The release is a technical certification, not a commercial one.

Question 41Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

What is the role of the competent authority in relation to Part-145 approvals?

  1. To issue Part-66 licences to the organisation's customers
  2. To perform all maintenance on behalf of the organisation
  3. To grant, oversee and where necessary limit, suspend or revoke the organisation's approval Correct answer.
  4. To set the organisation's commercial prices

Explanation

The competent authority grants Part-145 approvals and maintains oversight through auditing and findings. It may limit, suspend or revoke an approval where the organisation does not comply with the requirements.

Question 42Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

Under Part-66, what is the minimum age at which a person may be granted a licence?

  1. 18 years Correct answer.
  2. 16 years
  3. 25 years
  4. 21 years

Explanation

Part-66 requires an applicant for a licence to be at least 18 years of age. This is a basic eligibility condition alongside knowledge, experience and medical requirements.

Question 43Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

Under Part-M, what is the significance of an Airworthiness Directive (AD)?

  1. It is a mandatory requirement issued by the State of design or registry that must be complied with to maintain airworthiness Correct answer.
  2. It is a commercial service bulletin with no regulatory status
  3. It is an optional recommendation from the manufacturer
  4. It is a training syllabus issued by a Part-147 organisation

Explanation

An AD is a mandatory airworthiness requirement that must be complied with within the stated timescale to maintain the aircraft's airworthiness. Compliance must be recorded and managed through the continuing airworthiness system.

Question 44Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

A Part-145 organisation discovers that a component was fitted without the required documentation. What is the most appropriate initial action?

  1. Release the aircraft immediately and resolve the paperwork later
  2. Return the component to the store without recording the issue
  3. Fit the component to another aircraft to save time
  4. Quarantine the component and investigate the documentation and airworthiness status before further use Correct answer.

Explanation

Where documentation or airworthiness status is in doubt, the component must be controlled and investigated before use. This prevents unapproved parts from entering service and protects the organisation's compliance.

Question 45Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

What is the purpose of the Part-66 'basic knowledge' examination requirement?

  1. To certify that the applicant has a valid passport
  2. To prove that the applicant has completed a pilot course
  3. To replace all practical experience requirements
  4. To demonstrate that the applicant has the theoretical knowledge appropriate to the licence category and type Correct answer.

Explanation

The basic knowledge examinations confirm that the applicant has the theoretical understanding required for the licence category. This knowledge is then combined with the required practical experience and type-specific training where applicable.

Question 46Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

An operator under Part-M contracts a Part-145 organisation for maintenance. Which statement best reflects the division of responsibility?

  1. The Part-145 organisation assumes all continuing airworthiness responsibility from the operator
  2. The Part-145 organisation is responsible for the maintenance it performs, while the operator retains continuing airworthiness management responsibility Correct answer.
  3. The operator has no responsibility once a contract is signed
  4. The competent authority becomes responsible for the aircraft's maintenance

Explanation

The maintenance organisation is responsible for the work it performs and releases, while the operator remains responsible for continuing airworthiness management unless that responsibility is properly transferred under a contract to an approved organisation.

Question 47Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

A Part-66 licence holder is asked to certify a task that is outside the scope of their company authorisation. What is the correct course of action?

  1. Decline to certify the task and refer it to someone with the appropriate authorisation Correct answer.
  2. Ask the operator to sign the CRS instead
  3. Certify it provisionally and inform the authority afterwards
  4. Certify it because the licence category covers the aircraft generally

Explanation

A company authorisation defines the specific tasks and types a person may certify within the organisation. Certifying outside that scope would be a breach even if the licence category appears broad, so the task must be referred to an appropriately authorised person.

Question 48Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

A Part-145 organisation's quality system identifies a systemic weakness in its training records. Which approach best reflects the required quality management principle?

  1. Wait for the next authority audit to raise the issue
  2. Investigate the root cause and implement corrective action that addresses the system, then verify effectiveness Correct answer.
  3. Retrain one individual and close the finding without further review
  4. Record the finding but take no action if no incident has occurred

Explanation

Quality management requires root-cause analysis and systemic corrective action, followed by verification that the action is effective. Addressing only a symptom or waiting for external detection does not satisfy the organisation's obligations.

Question 49Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

Under Part-M, an aircraft has been stored for an extended period without maintenance. What must be considered before it returns to service?

  1. Whether the aircraft's paint scheme is still current
  2. Whether the operator has renewed its marketing contract
  3. Whether the maintenance programme and any storage requirements have been complied with, and whether an airworthiness review or certificate is valid Correct answer.
  4. Whether the flight crew has changed since storage

Explanation

Returning a stored aircraft to service requires confirmation that storage-related and scheduled maintenance has been accomplished and that continuing airworthiness documents remain valid. This ensures the aircraft's condition and records support lawful operation.

Question 50Aircraft maintenance licensing and continuing airworthiness regulatory framework (Part-66 / Part-M / Part-145 / Part-147)

A Part-147 organisation wishes to change its approved basic training syllabus. What is the regulatory expectation?

  1. The change may be made freely without any record
  2. The change must be managed within the approved change procedure and notified to or approved by the competent authority as required Correct answer.
  3. The change requires a new Part-145 approval
  4. The change must be approved by the aircraft manufacturer only

Explanation

Changes to approved training content must be controlled through the organisation's procedures and, where required, notified to or approved by the competent authority. This maintains the integrity of the approval and the credit given to graduates.
