Introduction
Analysis of the core content of the standard
| Module | Analysis basis | Key elements | Output results |
|---|---|---|---|
| System/Power Plant | ATA MSG-3 Analysis Procedure | MSI List, EWIS Inspection, LZHIRF Protection | Mission Interval Matrix (FC/FH/MO) |
| Structural Inspection | Damage Tolerance Assessment (CCAR25.571) | SSI List, CPCP Requirements, Fatigue Inspection | Corrosion Control Level Determination Criteria |
| Regional Inspection | SZA/EZAP Merger Analysis | Regional Division, GVI Task Merger | Approach Method Index Table |
Technological Evolution and Standard Background
This standard inherits and develops from the MSG-3 methodology, and innovatively incorporates the Electrical Wiring Interconnection System (EWIS) and Lightning Protection (LZHIRF) into an independent inspection system. Compared with the traditional outline:
- Corrosion protection is integrated from the independent CPCP outline into a structured task
- For the first time, the XML tagging specification of the digital maintenance outline is clarified (refer to GB/T 24463)
- A cross-indexing mechanism for regional inspection and system/structure tasks is established
Practical application of key terms
Major maintenance items (MSI)
Case: After a certain type of aircraft fuel pump was determined to be an MSI, three types of inspection tasks were generated through failure mode analysis:
- Visual inspection (every 500FH)
- Functional test (every 1500FC)
- Oil filter inspection (combined with engine replacement)
Implementation Recommendations
Outline Dynamic Maintenance Mechanism
| Phase | Work Focus | Partners |
|---|---|---|
| Initial Operation (0-2 years) | Collect Corrosion/Fatigue Data | Manufacturers + Operators |
| Maturity (2-5 years) | Optimize Inspection Intervals | MRB Working Group |
| Modification/Retrofit | Evaluate SSI/MSI Changes | Airworthiness Authorities |
Special note: Tasks marked with (EWIS) in the area inspection must be performed using special tooling
