What records and documentation are essential to complete for an overhaul?

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

Answer: (A)

The main idea here is that an overhaul needs complete, traceable documentation that proves every step, part, and action complies with both manufacturer data and regulatory requirements, and that the rebuilt engine or component actually functions as intended. Part serial numbers establish exactly which components were installed and their history, so you can trace life cycles and recalls. Wear measurements and clearances show that parts were checked and reworked to specification, confirming they meet required tolerances after overhaul. Compliance with ADs and SBs records any mandated actions that must be completed for airworthiness, ensuring the overhaul meets regulatory obligations. Recording repairs performed and parts replaced documents what was changed and why, providing a clear maintenance history for future work. Test results verify that, after assembly, the system passes the necessary functional, leak, and performance tests, proving it’s safe to operate. Choosing only a subset, like just parts replaced and test results, misses critical traceability and condition data. Focusing only on ADs/SBs misses the actual physical condition checks and the outcomes of testing. Recording only wear measurements omits the broader picture of what was repaired, what was replaced, and whether the unit actually performs to spec.
