Applicable National & International Requirements
The working documents — the maintenance programme and MSG-3, the manufacturer's data (AMM, IPC, WDM, SRM, CMM, SB), approved modifications and repairs, and reliability programmes.
National & international requirements — summary notes
Free- This sub-section pulls together the working documents and programmes that put the regulations into practice on the shop floor — maintenance programmes, ADs, MEL, modifications and repairs, and the manufacturer's maintenance documentation.
- The aircraft Maintenance Programme (AMP) defines the scheduled tasks and intervals for a specific aircraft; it is derived from the manufacturer's Maintenance Planning Document, itself developed using the MSG-3 analysis method, and is approved for the operator.
- Manufacturer's maintenance data the technician works to includes: the Aircraft Maintenance Manual (AMM), Illustrated Parts Catalogue (IPC), Wiring Diagram Manual (WDM), Structural Repair Manual (SRM), Component Maintenance Manuals (CMM) and Service Bulletins (SB). Work must be to the current approved issue.
- Modifications and repairs must be carried out to approved data — an SRM scheme, an AMM procedure, an STC, or an authority/DOA-approved repair design — and recorded. A repair outside published limits needs specific approval before embodiment.
- Reliability programmes monitor in-service data (defects, removals, delays) to confirm the maintenance programme is effective and to justify adjusting task intervals — the feedback loop that keeps the AMP appropriate.
- The MEL/MMEL, Configuration Deviation List and Airworthiness Directives (from Module 10.4 and 10.6) all feed the day-to-day dispatch and airworthiness decisions the documentation supports.
- ⚠ Exam trap: always work to the CURRENT approved data at its latest issue; a repair beyond the published SRM limits is not a free-hand job — it needs specific approved repair data first.

A dented skin panel is outside the damage limits published in the Structural Repair Manual. Can the technician design and carry out a repair on the spot?
No. The SRM covers repairs within its published limits; damage beyond those limits requires specific approved repair data — obtained from the manufacturer or an approved design organisation/authority — before any repair is embodied. Working outside the SRM without that approval is not permitted.
Which manufacturer document gives the part numbers and assembly breakdown needed to order the correct replacement part?
The Illustrated Parts Catalogue (IPC), which shows the exploded assemblies and part numbers. The removal/installation procedure would be found in the Aircraft Maintenance Manual (AMM); the two are used together.
