Aircraft Maintenance and Continuing Airworthiness (Part-66 domain)
Map the Part-66 licence categories (A, B1, B2, B3, C, and the L categories) and state for each the certification privileges, the basic experience requirement, and which aircraft or system types it covers, writing the comparison in your own words.
Trace the continuing airworthiness chain from the type-certificate holder through the design approval, the operator, and the maintenance organisation, and explain in writing who is responsible at each link for airworthiness data reaching the line engineer.
List the components of a maintenance programme (scheduled tasks, thresholds, intervals, escalation, and the operator's responsibility to have it approved) and explain how a task is added, deleted, or escalated under the applicable Part-66 domain rules.
Distinguish airworthiness directives, service bulletins, and mandatory continuing airworthiness information, and state the compliance obligation and record-keeping duty attached to each.
Define the categories of maintenance (scheduled, unscheduled, line, base) and match each to the Part-66 licence holder who may certify it.
Your checkpoint
A one-page A3 mind map of the continuing airworthiness chain with every actor, document, and responsibility labelled, plus a 20-term glossary written from memory and checked against your notes.
Aircraft Maintenance and Continuing Airworthiness (Part-66 domain)
Explain the role of the continuing airworthiness management exposition and list the information a certifying engineer must be able to find in it.
Describe the aircraft technical log, the certificate of release to service, and the maintenance record requirements, and state how long each record must be retained and by whom.
Work through the mass and balance, and configuration-deviation, reporting duties that fall on maintenance staff, and state who is notified and when.
Explain the purpose of the airworthiness review certificate, who may issue it, and how the review interacts with the maintenance programme and defect history.
Your checkpoint
A written 600-word case study of one aircraft's annual cycle (check, defect, AD compliance, release, airworthiness review) with every responsible person and document named and every record retention period stated.
Aircraft Maintenance and Continuing Airworthiness (Part-66 domain) & Continuing Airworthiness Organisations (Part-CAMO, Part-CAO)
Transition from the Part-66 domain into Part-CAMO by mapping each continuing airworthiness management task to the CAMO function that owns it.
Compare Part-CAMO with Part-CAO and state, for a small operator, which organisation is appropriate and why, giving at least three distinguishing criteria.
List the Part-CAMO approval scope items (aircraft types and the continuing airworthiness management tasks) and explain how a scope is extended or varied.
Explain the role of the continuing airworthiness management organisation's safety and quality interface and how findings are raised and closed.
Your checkpoint
A two-column comparison table of Part-CAMO versus Part-CAO covering approval basis, scope, personnel requirements, and subcontracting, with at least 12 rows completed from memory and then verified.
Continuing Airworthiness Organisations (Part-CAMO, Part-CAO)
Describe the nominated persons required by a continuing airworthiness management organisation and state the qualifications and responsibilities of each.
Explain the maintenance programme development and approval process a CAMO performs, including the reliability programme where applicable.
Outline the CAMO's quality system, its audit cycle, and how it interfaces with the competent authority's oversight.
Explain subcontracting and the conditions under which a CAMO may contract out continuing airworthiness management tasks, and the responsibility that remains in-house.
Your checkpoint
A mock CAMO exposition table of contents annotated in your own words, with a short note against each section saying what an auditor would look for.
Maintenance Organisations (Part-145)
Map the Part-145 approval classes and ratings to the maintenance they authorise, and state what an organisation must hold to release a given task.
Explain the Part-145 personnel requirements, including the accountable manager, the nominated postholders, and the certifying staff qualification routes.
Describe the certifying staff authorisation process, the scope of the authorisation, and the conditions under which it may be limited or withdrawn.
Explain the Part-145 quality system, the independent audit function, and the finding classification and closure process.
Your checkpoint
A one-page flowchart of the certifying staff authorisation route from recruitment to first release, with every gate (experience, type training, assessment, authorisation) and the evidence required at each.
Maintenance Organisations (Part-145) & Continuing Airworthiness Organisations (Part-CAMO, Part-CAO)
Explain the maintenance organisation exposition, its approval, and the change notification duties to the competent authority.
Describe the interface between a Part-145 organisation and a CAMO, covering work orders, task cards, deferred defects, and release back to the operator.
Explain the conditions for issuing a certificate of release to service, including the role of the approved data and the independent inspection where required.
Outline the Part-145 requirements for facilities, tooling, calibration, and stores, and how each is audited.
Your checkpoint
A 500-word written procedure for handling a defect found during a scheduled check, from discovery through deferral or rectification to release, naming every document and signatory.
Maintenance Training Organisations (Part-147)
Explain the Part-147 approval scope for basic training, type training, and examinations, and state what each approval authorises.
Describe the Part-147 personnel and facility requirements, including instructors, examiners, and the knowledge and practical assessment standards.
Outline the Part-147 quality system and the record-keeping duties for trainee records, examination results, and certificates issued.
Explain how a Part-147 certificate of recognition is used in the Part-66 licence application and what the training organisation must certify.
Your checkpoint
A sample Part-147 training syllabus outline for one aircraft type, covering knowledge modules, practical elements, examination, and the records generated, written from your own understanding.
Aircraft Maintenance and Continuing Airworthiness (Part-66 domain) & Continuing Airworthiness Organisations (Part-CAMO, Part-CAO) & Maintenance Organisations (Part-145) & Maintenance Training Organisations (Part-147)
Reconcile the four domains by building a single responsibility matrix showing, for ten common maintenance events, which organisation and which person owns each step.
Sit two full timed mock papers under exam conditions and record your score per domain.
Re-study only the two weakest sub-topics identified by the mock results and write a one-page correction sheet for each.
Recite the key definitions (continuing airworthiness, maintenance, release to service, airworthiness review) from memory and check them word for word against the regulation text.
Your checkpoint
A completed responsibility matrix plus a mock exam score sheet showing per-domain percentages, with both mock scores at or above 75 percent overall and no domain below 65 percent.
Milestones
Week 2: Without notes, explain the full continuing airworthiness chain and the record retention rules to another person for ten minutes; they should be able to repeat the chain back to you.
Week 4: Score at least 70 percent on a 30-question self-written test covering domains 1 and 2, and correctly state the Part-CAMO versus Part-CAO distinction in under two minutes.
Week 6: Correctly describe the Part-145 certifying staff authorisation route and the CRS conditions in writing, with no reference material, and pass a 20-question domain 3 self-test at 70 percent or above.
Week 8: Achieve at least 75 percent overall on two timed full mock papers, with no single domain below 65 percent, and have every correction sheet reviewed and closed.
