What items must be recorded as part of overhaul documentation?

• A. Part serial numbers, wear measurements, clearances, AD/SB compliance, repairs, parts replaced, and test results.
• B. Only the parts replaced.
• C. Only the test results.
• D. Only wear measurements.

Answer: (A)

Overhaul documentation is about traceability and verification to prove airworthiness. When you overhaul a reciprocating engine, you must capture every element that shows what was done, what was found, and how the engine was tested before it returns to service. This means recording part serial numbers for traceability, wear measurements and clearances to confirm components are within specification, compliance with applicable ADs and SBs to show regulatory and manufacturer directives were followed, details of repairs and all parts replaced to document the restoration, and the test results that demonstrate the engine meets performance and safety standards. If you only record one aspect, you lack the full picture needed to prove the overhaul was done correctly and to support future maintenance or inspections. For example, recording only parts replaced misses how the engine's wear limits were verified, and skipping AD/SB compliance or test results leaves important regulatory and performance validation unshown. The complete documentation package brings together all these elements, which is why the best answer includes all of them.
