What type of inspection is typically performed after an engine has been overhauled?

• A. Operational test inspection
• B. Comprehensive visual inspection
• C. Return-to-service inspection
• D. Routine pre-flight inspection

Answer: (C)

The typical inspection performed after an engine has been overhauled is the return-to-service inspection. This inspection is crucial as it ensures that the engine meets the required safety and performance standards before it is put back into operation. A return-to-service inspection verifies that all components have been properly assembled, necessary repairs have been completed according to manufacturer specifications, and that the engine operates safely and efficiently.

This inspection involves a thorough review of all work performed during the overhaul process, including corrective measures taken and any parts that were replaced. Documentation and compliance with regulatory standards are also evaluated to ensure that everything is in line with FAA guidelines before the engine is deemed fit for service.

While other inspections such as operational tests or visual checks may also occur in the maintenance process, none are as specifically designated to confirm readiness for service post-overhaul as the return-to-service inspection.
