FAA Aviation Mechanic Powerplant (AMP)Engine InspectionEasy
During a 100-hour inspection required by 14 CFR Part 43, Appendix D, a technician is reviewing the powerplant inspection checklist. Which of the following is specifically listed as an item that must be inspected on the engine group?
- AEngine mounts for cracks and looseness
- BLanding gear shock strut inflation
- CWing spar attachment fittings
- DStatic wick continuity
Show answer & explanationAnswer & explanation
Correct answer: A. Engine mounts for cracks and looseness
14 CFR 43 Appendix D specifically lists 'engine mounts for cracks, looseness of mounting, and looseness of engine to mount' as a required inspection item under the powerplant group. The other items belong to airframe/gear/electrical systems, not the engine group.
Why the other options are wrong
- B. Shock strut inflation is a landing gear item.
- C. Wing spar fittings are an airframe item, not powerplant.
- D. Static wicks relate to the electrical/airframe system.
14 CFR 43 Appendix D
Regulation listing the minimum required items for annual and 100-hour inspections, divided into airframe, engine, and other groups.

- 100-hour inspections use the same scope as annual inspections
- Appendix D is the baseline checklist mechanics must follow
Memory trick: 'Mounts Move the Motor' — check engine mounts first in the powerplant group
