Part-66 Module 10 · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Continuing Airworthiness

  • Define continuing airworthiness and list the responsibilities of the owner/operator versus the maintenance organisation

  • Explain the airworthiness limit concept: life-limited parts, maintenance task intervals and permitted deviations

  • Describe the role of the type certificate holder, supplemental type certificates and approved design data in keeping an aircraft airworthy

  • Trace how a defect found in service flows from discovery through deferral, rectification and record entry

Your checkpoint

A one-page process map of the continuing airworthiness loop (defect → assessment → rectification → record → release) with each step annotated in your own words

Week 2

Continuing Airworthiness & Regulatory Framework

  • Interpret maintenance programme content: scheduled tasks, intervals, escalation and approved variations

  • Differentiate mandatory continuing airworthiness information from non-mandatory service information and state the action each requires

  • Summarise how airworthiness directives are issued, recorded and embodied, including the meaning of an alternative method of compliance

  • Map which regulation-making body sets the requirement at each stage of the directive process

Your checkpoint

A comparison table of three categories of continuing airworthiness information (directive, mandatory service bulletin, recommended service bulletin) showing issuer, obligation and documentation produced

Week 3

Regulatory Framework & Continuing Airworthiness

  • Outline the regulatory framework structure: international convention level, regional rule-making level, national authority level

  • Explain how a national authority delegates and oversees maintenance standards and what an acceptable means of compliance is

  • Describe the role of the maintenance review board and the industry steering committee in producing a maintenance programme

  • Link two continuing airworthiness requirements back to the regulation that creates them

Your checkpoint

A layered diagram of the regulatory framework with at least six named bodies/instruments placed at the correct layer, plus a short note on how a rule becomes applicable to a maintenance organisation

Week 4

Applicable National and International Requirements (ICAO, national authorities) & Regulatory Framework

  • Summarise the ICAO annex provisions that govern personnel licensing and aircraft maintenance, and distinguish standards from recommended practices

  • Explain how national requirements differ from and build on ICAO standards, including the concept of differences filed

  • Compare certification specifications and acceptable means of compliance across two national/regional systems

  • State the record-keeping and reporting obligations that recur across international requirements

Your checkpoint

A two-column comparison of ICAO standards versus national implementing rules for maintenance personnel and organisations, covering at least five points of comparison

Week 5

Approved Maintenance Organisations & Certifying Staff - Maintenance

  • Describe the scope of an approved maintenance organisation approval and the ratings under which work may be performed

  • Explain the role, qualifications and limitations of certifying staff, support staff and category-specific authorisations

  • Outline the organisation's obligations for facility, tooling, stores, training and quality monitoring

  • Explain how a finding from a quality audit becomes a corrective action and how the authority verifies closure

  • Distinguish the privileges and limits of a certifying staff authorisation from those of a component or line certifying staff

Your checkpoint

A checklist of ten questions you would ask to audit whether a maintenance organisation's scope of approval actually matches the work in its hangar

Week 6

Certification of Aircraft, Parts and Appliances & Certifying Staff - Maintenance

  • Explain what a certificate of release to service certifies and who is entitled to issue it

  • List the documentation required before release: work cards, parts traceability, test results and outstanding deferred items

  • Describe how parts and appliances are approved for installation, including the status of standard parts and uncertified parts

  • Explain the purpose and limits of an authorised release certificate for a component

  • Identify the circumstances in which an aircraft may be released with an accepted non-compliance or deferred defect

Your checkpoint

A completed sample release-to-service decision sheet for three hypothetical scenarios (routine check, component replacement, deferred defect carried forward) with a justified decision for each

Week 7

Air Operations & Certification of Aircraft, Parts and Appliances

  • Outline the operator's responsibilities that interact with maintenance: operational control, minimum equipment list use and defect reporting

  • Explain how a minimum equipment list entry is used to defer a defect and what conditions must be met before dispatch

  • Describe continuing airworthiness management tasks carried out on behalf of an operator

  • Link crew-reported defects to the maintenance and record-keeping chain

Your checkpoint

A worked example of a minimum equipment list deferral: entry conditions, maintenance action, placarding, documentation and the date by which rectification must occur

Week 8

Continuing Airworthiness & Regulatory Framework & Applicable National and International Requirements (ICAO, national authorities) & Certifying Staff - Maintenance & Approved Maintenance Organisations & Certification of Aircraft, Parts and Appliances & Air Operations

  • Re-test every domain under timed conditions and log a score per domain

  • Rewrite your weakest three topic summaries from memory without notes

  • Resolve every flagged uncertain fact by checking an authoritative primary source

  • Consolidate record-keeping and release-to-service rules into a single revision sheet, since they appear across several domains

Your checkpoint

A timed 60-question self-test with per-domain scores recorded, plus a one-page final revision sheet covering releases, records and continuing airworthiness information

Milestones

Week 2: Can explain, without notes, how a defect leads to a directive and back into the maintenance programme - scored against your week 1 process map

Week 4: Regulatory-framework diagram complete and correct; self-test score of at least 70% on domains 10.1 and 10.7

Week 6: Can issue a defensible release-to-service decision for all three scenario types in the week 6 deliverable, citing the documents relied on

Week 7: All seven domains have at least one set of notes and one self-test attempt recorded

Week 8: Timed self-test complete at 75% or above overall with no single domain below 65%
