ACS ACS Quality & Compliance 2 — Questions and Answers
Question 1: Under 14 CFR Part 43, who is responsible for ensuring a maintenance record entry is made after completing an inspection?
- The aircraft owner
- The person who performed the work (Correct answer)
- The FAA inspector
- The repair station manager
Correct answer: The person who performed the work
14 CFR 43.9 requires the person who performed the maintenance to make the appropriate record entry.
Question 2: What is the purpose of an Airworthiness Directive (AD)?
- To recommend optional upgrades
- To mandate corrective action for unsafe conditions (Correct answer)
- To approve new parts for installation
- To document scheduled maintenance intervals
Correct answer: To mandate corrective action for unsafe conditions
ADs are legally enforceable regulations issued by the FAA to correct unsafe conditions found in aircraft, engines, propellers, or appliances.
Question 3: A mechanic discovers an Airworthiness Directive applies to a component already installed on an aircraft. The AD has a compliance time of 'next scheduled inspection.' What must the mechanic do?
- Note it in the logbook and defer until owner requests it
- Ground the aircraft immediately
- Comply with the AD at or before the next scheduled inspection (Correct answer)
- Contact the FAA for an exemption
Correct answer: Comply with the AD at or before the next scheduled inspection
The compliance time stated in the AD establishes the deadline; the mechanic must accomplish it no later than that time.
Question 4: Which document establishes the approved data a mechanic must use when performing a major repair?
- The aircraft logbook
- FAA-approved data such as AMM, SRM, or FAA-accepted engineering order (Correct answer)
- The manufacturer's service letter
- The parts manual
Correct answer: FAA-approved data such as AMM, SRM, or FAA-accepted engineering order
Major repairs must be performed per FAA-approved data; unapproved data (e.g., service letters alone) is insufficient without FAA acceptance.
Question 5: A TSO authorization granted to a manufacturer signifies that the article:
- Has been approved for installation on any aircraft
- Meets the minimum performance standards of the TSO (Correct answer)
- Is exempt from AD compliance
- Has been certified for 10,000 flight hours
Correct answer: Meets the minimum performance standards of the TSO
A TSO authorization means the article was produced to meet FAA minimum performance standards, but installation approval is still required.
Question 6: When may a certificated mechanic return an aircraft to service after performing a major alteration?
- After completing a test flight
- Only after FAA Form 337 is approved by the local FSDO
- After completing the work and making proper maintenance record entries with approved data
- Only if the mechanic holds an Inspection Authorization (Correct answer)
Correct answer: Only if the mechanic holds an Inspection Authorization
Returning an aircraft to service after a major alteration requires an IA or DAR, not just a basic A&P certificate.
Question 7: Which FAR part primarily governs the maintenance, preventive maintenance, rebuilding, and alteration of aircraft?
- 14 CFR Part 21
- 14 CFR Part 39
- 14 CFR Part 43 (Correct answer)
- 14 CFR Part 65
Correct answer: 14 CFR Part 43
14 CFR Part 43 specifically regulates the performance of maintenance, preventive maintenance, rebuilding, and alteration of aircraft.
