ACS Aviation Regulations & Safety Procedures 3 — Questions and Answers
Question 1: A mechanic with only an Airframe rating discovers a malfunctioning magneto during an inspection. What action may the mechanic legally take?
- Repair and test the magneto since it is attached to the airframe
- Remove the magneto and return it to the owner with a written discrepancy notice (Correct answer)
- Perform any repair on the magneto because it directly affects flight safety
- Replace the magneto with an approved unit and approve the aircraft for return to service
Correct answer: Remove the magneto and return it to the owner with a written discrepancy notice
A mechanic with only an Airframe rating cannot perform powerplant maintenance; they must note the discrepancy and inform the owner.
Question 2: According to 14 CFR Part 43, Appendix D, what inspection items are specifically included in the scope of a 100-hour inspection?
- Only the engine and propeller systems
- All items listed in Appendix D covering airframe, engine, propeller, and emergency equipment (Correct answer)
- A visual inspection of the exterior only
- Items specified by the aircraft manufacturer's maintenance manual only
Correct answer: All items listed in Appendix D covering airframe, engine, propeller, and emergency equipment
Appendix D of Part 43 defines the scope of 100-hour and annual inspections, encompassing airframe, engine, propeller, and emergency equipment items.
Question 3: What does a Special Airworthiness Certificate in the Experimental category allow an aircraft owner to do?
- Operate the aircraft in commercial air carrier service
- Conduct research, development, and flight testing outside standard category limitations (Correct answer)
- Operate with unlimited passengers for hire
- Bypass all Airworthiness Directives applicable to standard category aircraft
Correct answer: Conduct research, development, and flight testing outside standard category limitations
An Experimental certificate is issued for specific purposes such as research, development, and amateur-building, with operating limitations imposed by the FAA.
Question 4: Which regulatory document must a certificated repair station reference to ensure it is performing maintenance within its approved ratings?
- FAA Order 8900.1
- The repair station's Operations Specifications and Repair Station Manual (Correct answer)
- AC 43.13-1B exclusively
- The aircraft's Pilot Operating Handbook
Correct answer: The repair station's Operations Specifications and Repair Station Manual
Repair stations must operate in accordance with their Operations Specifications and Repair Station Manual, which define the scope of their approved ratings.
Question 5: A mechanic performing a required inspection on a pressurized aircraft must ensure that the aircraft's pressurization system inspection is accomplished:
- Only when the owner requests it as an added service
- As part of the required inspection items per Part 43, Appendix D (Correct answer)
- Only by a repair station with a pressurization specialization rating
- Every 500 hours regardless of other inspection intervals
Correct answer: As part of the required inspection items per Part 43, Appendix D
Pressurization system checks are included in the inspection requirements under Part 43 Appendix D for aircraft equipped with such systems.
Question 6: Under 14 CFR 65.81, a certificated mechanic may exercise the privileges of their certificate only if they have:
- Passed a practical test within the last 24 months
- Served as a pilot-in-command within the preceding 6 months
- Performed work in their certificate's category within the preceding 24 months (Correct answer)
- Attended an FAA safety seminar within the preceding 12 months
Correct answer: Performed work in their certificate's category within the preceding 24 months
14 CFR 65.81 requires that a mechanic have performed work in the applicable category or subcategory within the preceding 24 months to exercise certificate privileges.
Question 7: What is the purpose of a Continued Airworthiness Maintenance Program (CAMP) as referenced in 14 CFR Part 91 Subpart K?
- To replace the need for annual inspections on all aircraft
- To provide a structured maintenance program for fractional ownership aircraft operations (Correct answer)
- To allow experimental aircraft to operate under standard category rules
- To authorize owner-performed maintenance on light sport aircraft
Correct answer: To provide a structured maintenance program for fractional ownership aircraft operations
A CAMP under Part 91 Subpart K provides fractional ownership program aircraft with an approved, structured maintenance schedule in lieu of standard inspection requirements.
