FAA Aviation Mechanic Airframe (AMA)Airframe InspectionEasy
A technician is scheduling a 100-hour inspection on a Cessna 172 used for flight instruction. Which statement about the scope of this inspection is correct?
- AIt may only be performed by an Inspection Authorization (IA) holder
- BIt uses the same scope and detail as an annual inspection per 14 CFR 43.15
- CIt replaces the need for an annual inspection permanently
- DIt is less detailed than an annual and only covers the engine
Show answer & explanationAnswer & explanation
Correct answer: B. It uses the same scope and detail as an annual inspection per 14 CFR 43.15
14 CFR 43.15 states that the scope and detail of items in a 100-hour inspection are the same as an annual inspection, though a 100-hour inspection may be performed by any certificated A&P mechanic, not just an IA.
Why the other options are wrong
- A. Any A&P mechanic may perform a 100-hour inspection, not just an IA
- C. An annual is still required annually regardless of 100-hour inspections
- D. It covers the entire aircraft, not just the engine
100-Hour Inspection
A required inspection for aircraft used for hire or flight instruction, performed every 100 hours of flight time, with the same scope as an annual inspection.
- Required under 14 CFR 91.409 for aircraft used commercially or for instruction
- Scope matches annual inspection per 43.15
- Can be performed by any certificated A&P mechanic
Memory trick: 100-hour = Annual twin, but A&P can sign it
