- Any certificated pilot with a commercial certificate
- A certificated mechanic with an Airframe & Powerplant (A&P) rating (Correct answer)
- Only the aircraft manufacturer's designated representative
- Any person holding a valid repairman certificate
Correct answer: A certificated mechanic with an Airframe & Powerplant (A&P) rating
FAR Part 43 requires 100-hour inspections to be performed by a certificated mechanic holding at least an A&P rating.
Question 2: An aircraft's Airworthiness Directive (AD) requires repetitive compliance. The maintenance record entry must include which of the following?

Question 3: A pilot reports an unusual vibration from the engine during cruise flight. As an ASI, which initial inspection step is most appropriate?
- Immediately ground the aircraft pending engine teardown
- Review the aircraft maintenance logs and recent squawk history before determining further action (Correct answer)
- Issue an emergency AD requiring all similar aircraft to be grounded
- Request the pilot perform additional flight tests to reproduce the vibration
Correct answer: Review the aircraft maintenance logs and recent squawk history before determining further action
Reviewing maintenance logs and squawk history provides the necessary context before determining the appropriate level of inspection.
Question 4: Which document defines the acceptable means of compliance for an aircraft's continued airworthiness?
- The Pilot's Operating Handbook (POH)

- The Certificate of Registration
Correct answer: The Aircraft Maintenance Manual (AMM) approved by the FAA
The FAA-approved Aircraft Maintenance Manual provides the standard acceptable means of compliance for continued airworthiness.

- The aircraft owner's personal logbook
- The Minimum Equipment List (MEL) or corrective action before the next revenue flight (Correct answer)
- A verbal authorization from the Director of Operations
- A signed waiver from the FAA Flight Standards District Office
Correct answer: The Minimum Equipment List (MEL) or corrective action before the next revenue flight
Under Part 121, all discrepancies must be resolved through the MEL process or corrective maintenance before the next revenue departure.
