AM Inspection & Quality Control 2 — Questions and Answers
Question 1: Which document authorizes return-to-service after a major repair on a certificated aircraft?
- FAA Form 337 (Correct answer)
- FAA Form 8130-3
- FAA Form 8060-4
- FAA Form 8710-1
Correct answer: FAA Form 337
FAA Form 337 (Major Repair and Alteration) must be completed and submitted to the FAA for major repairs on certificated aircraft.
Question 2: During a required inspection, an IA discovers a crack in a primary structural member. Which action is required FIRST?
- Ground the aircraft and notify the owner (Correct answer)
- Repair the crack immediately
- Issue a ferry permit
- Log the finding and continue the inspection
Correct answer: Ground the aircraft and notify the owner
A crack in a primary structural member renders the aircraft unairworthy; it must be grounded and the owner notified before any other action.
Question 3: What is the primary purpose of a Receiving Inspection in an aircraft maintenance facility?
- To verify parts and materials meet specifications before use (Correct answer)
- To test completed assemblies before installation
- To audit supplier quality management systems
- To calibrate incoming test equipment
Correct answer: To verify parts and materials meet specifications before use
Receiving inspection ensures incoming parts, materials, and components conform to purchase order specifications before they enter the production or repair process.
Question 4: Under 14 CFR Part 145, a repair station's Quality Control manual must include procedures for:
- Calibration and control of inspection tools and equipment (Correct answer)
- Pilot training programs
- ATC communication protocols
- Airport ground movement procedures
Correct answer: Calibration and control of inspection tools and equipment
Part 145 repair stations are required to maintain calibration control procedures for all inspection tools and equipment in their QC manual.
Question 5: What does a 'red tag' placed on an aircraft part typically indicate in a maintenance shop?
- The part is unserviceable and must not be installed (Correct answer)
- The part is awaiting final inspection approval
- The part is serviceable and ready for installation
- The part requires lubrication before use
Correct answer: The part is unserviceable and must not be installed
A red tag is used universally in aviation maintenance to identify unserviceable parts that must be segregated and not installed on aircraft.
Question 6: Which NDT method is MOST effective for detecting subsurface fatigue cracks in aluminum wing spar caps?
- Eddy current inspection (Correct answer)
- Dye penetrant inspection
- Visual inspection
- Magnetic particle inspection
Correct answer: Eddy current inspection
Eddy current inspection is ideal for detecting subsurface cracks in non-ferrous metals like aluminum, making it preferred for wing spar inspections.
Question 7: An airworthiness directive (AD) requires repetitive inspections at 100-hour intervals. The aircraft is currently at 2,347 hours. At what total time is the NEXT inspection due?
- 2,400 hours (Correct answer)
- 2,347 hours
- 2,447 hours
- 2,300 hours
Correct answer: 2,400 hours
Repetitive ADs are complied with at the next interval boundary; rounding up to the nearest 100-hour increment from 2,347 gives 2,400 hours.
