CAM Aircraft Maintenance 2 — Questions and Answers
Question 1: Under which FAR part is a business aviation flight department typically required to use a Continuous Airworthiness Maintenance Program (CAMP) rather than annual/100-hour inspections?
- Part 21 for newly certificated aircraft
- Part 61 for all turbine aircraft
- Part 147 for corporate operators
- Part 91 Subpart K and Part 135 for aircraft with 10 or more passenger seats (Correct answer)
Correct answer: Part 91 Subpart K and Part 135 for aircraft with 10 or more passenger seats
Part 91 Subpart K fractional programs and Part 135 operators of larger aircraft must maintain aircraft under a CAMP.
Question 2: An aviation manager discovers an aircraft flew with an overdue Airworthiness Directive (AD). What is the most immediate consequence?
- Nothing, if the aircraft is operated under Part 91
- Only the manufacturer is liable
- The aircraft was legally unairworthy during those flights (Correct answer)
- The AD deadline is automatically extended
Correct answer: The aircraft was legally unairworthy during those flights
Operating with an AD not complied with by its deadline renders the aircraft unairworthy and violates FAR 39.7.
Question 3: Which document must a mechanic record a maintenance entry in before an aircraft is approved for return to service?
- The pilot's personal logbook
- The minimum equipment list
- The insurance policy declarations page
- The aircraft maintenance records (logbooks) (Correct answer)
Correct answer: The aircraft maintenance records (logbooks)
FAR 43.9 requires maintenance entries in the aircraft's maintenance records before return to service.
Question 4: A flight department wants to defer repair of an inoperative item on a turbojet and continue flying. Under Part 91, what generally allows this?
- A verbal waiver from the local FSDO inspector
- The director of maintenance's written memo
- An approved Minimum Equipment List (MEL) with a Letter of Authorization (Correct answer)
- The aircraft flight manual supplement
Correct answer: An approved Minimum Equipment List (MEL) with a Letter of Authorization
An FAA-issued Letter of Authorization makes the approved MEL the vehicle for legally deferring inoperative equipment.
Question 5: In budgeting for maintenance, which cost model spreads engine overhaul expenses into a predictable per-flight-hour accrual?
- Straight-line depreciation of the airframe
- Time-and-materials invoicing after each shop visit
- Capitalizing overhauls as new aircraft acquisitions
- An hourly engine maintenance program such as a power-by-the-hour plan (Correct answer)
Correct answer: An hourly engine maintenance program such as a power-by-the-hour plan
Guaranteed hourly maintenance programs convert large, irregular overhaul costs into predictable per-hour accruals.
Question 6: Which inspection concept applies calendar time, flight hours, or cycles to determine when a component must be removed regardless of condition?
- On-condition monitoring
- Reliability-centered sampling
- Condition monitoring
- Hard-time limit (Correct answer)
Correct answer: Hard-time limit
Hard-time items must be overhauled or replaced at fixed intervals regardless of apparent condition.
Question 7: A CAM should recognize that a Service Bulletin (SB) issued by the manufacturer is generally what for a Part 91 operator?
- Applicable only to aircraft on foreign registries
- Always mandatory within 30 days
- Advisory unless mandated by an AD or required by the operator's program (Correct answer)
- Binding only if the aircraft is financed
Correct answer: Advisory unless mandated by an AD or required by the operator's program
Service Bulletins are optional for most Part 91 operators unless incorporated by an AD or the operator's own approved program.
