Lessons Learned
4.4.5 Engine examination. The engine with all accessories specified in 3.4.5 will be
examined for completeness, proper installation in vehicle, electrical hookups, fuel and air line
connections, mechanical control hookups, oil level, and cooling fluid hookups.
Verification Rationale
Verification of the engine installation and proper attachment of all related components must
be ascertained to assure the performance of the engine and to preclude engine failure because of
fluid leaks or failure to perform due to disconnection of linkages and components.
Verification Guidance
Preparation and use of an inspection check sheet, such as a Final Inspection Record (FIR),
citing all the accessories, components, adjustments, and connections will provide a documented
record and assurance that proper installation has been accomplished.
Verification Lessons Learned
