- An FAA-certificated IA (Inspection Authorization) holder (Correct answer)
- Any certificated A&P mechanic
- The aircraft owner
- An FAA Safety Inspector only
Correct answer: An FAA-certificated IA (Inspection Authorization) holder
Major repairs must be approved for return to service by an IA holder, an FAA representative, or a certificated repair station.
Question 2: What form is used to record a major repair or major alteration on an aircraft?
- FAA Form 337 (Correct answer)
- FAA Form 8130-3
- FAA Form 8110-3
- FAA Form 8130-9
Correct answer: FAA Form 337
FAA Form 337 (Major Repair and Alteration) is the required document for recording major repairs and alterations to aircraft.
Question 3: Which publication would a mechanic consult to find the specific tasks required during a scheduled heavy maintenance check on a Part 121 air carrier aircraft?
- The carrier's FAA-approved Continuous Airworthiness Maintenance Program (CAMP) (Correct answer)
- AC 43.13-1B
- 14 CFR Part 43 Appendix D
- The manufacturer's Parts Catalog
Correct answer: The carrier's FAA-approved Continuous Airworthiness Maintenance Program (CAMP)
Part 121 air carriers use an FAA-approved CAMP that specifies all scheduled maintenance tasks and intervals.
Question 4: ASTM International standards referenced by the FAA for Light Sport Aircraft (LSA) maintenance are considered:
- Consensus standards accepted by the FAA (Correct answer)
- Mandatory FAA regulations
- Advisory only, with no legal standing
- Equivalent to military specifications
Correct answer: Consensus standards accepted by the FAA
The FAA accepts ASTM consensus standards for LSA design and maintenance as a valid means of compliance.
Question 5: A mechanic finds a cracked engine mount on a certificated aircraft. Replacing the mount with an identical part from the manufacturer is classified as a:
- Major repair requiring Form 337 (Correct answer)
- Minor repair requiring only a logbook entry
- Preventive maintenance item
- Condition-monitored task
Correct answer: Major repair requiring Form 337
Engine mount replacement is listed as a major repair in 14 CFR Part 43 Appendix A and requires FAA Form 337.
Question 6: What is the primary purpose of a Supplemental Type Certificate (STC)?
- To approve a modification that changes the original type design of a certificated product (Correct answer)
- To certify a new aircraft design from scratch
- To authorize a mechanic to perform experimental aircraft work
- To extend the operating limits of an existing type certificate
Correct answer: To approve a modification that changes the original type design of a certificated product
An STC approves a design change to an already type-certificated product, allowing installation of non-original equipment or modifications.
Question 7: Under 14 CFR 91.409, an aircraft operated for hire requiring a 100-hour inspection must have the inspection performed within what tolerance?
- Within 10 hours after the due time (Correct answer)
- Exactly at 100 hours with no tolerance
- Within 5 hours before or after the due time
- Within 25 hours after the due time
Correct answer: Within 10 hours after the due time
14 CFR 91.409 allows a 10-hour tolerance beyond the 100-hour interval, but the next interval is calculated from when it was due, not when it was done.
