Read the first 7 Aircraft Maintenance Safety & Regulatory Compliance flashcards as text

  1. Under 14 CFR Part 91.409, what is the maximum interval between required 100-hour inspections for an aircraft operated for hire?

    Answer: 110 hours

    14 CFR 91.409(b) allows up to 10 hours over the 100-hour interval if necessary to reach a maintenance facility, making the maximum 110 hours.

  2. Which personal protective equipment (PPE) is specifically required when working with liquid oxygen (LOX) systems on aircraft?

    Answer: Cryogenic gloves, face shield, and fire-resistant clothing

    Liquid oxygen is extremely cold and a powerful oxidizer, requiring cryogenic-rated gloves, a face shield, and fire-resistant clothing to protect against burns and fire.

  3. What is the maximum allowable time for an A&P mechanic to complete an IA (Inspection Authorization) renewal after it expires?

    Answer: IA cannot be renewed — a new one must be obtained

    An Inspection Authorization expires on March 31 each year and cannot be renewed after expiration; a new IA application must be submitted.

  4. A maintenance technician inadvertently installs a bolt that is 0.25 inch shorter than specified. This is BEST classified as:

    Answer: A maintenance error requiring immediate corrective action

    Installing a non-specified fastener is a maintenance error; the correct bolt must be installed per the manufacturer's data before the aircraft can be returned to service.

  5. Continuous Airworthiness Maintenance Programs (CAMP) are typically used by operators under which FAR?

    Answer: 14 CFR Part 135 air carrier operations

    CAMP programs are used under 14 CFR Part 135 (and Part 121) air carrier operations to replace traditional time-limited inspections with manufacturer-defined maintenance tasks.

  6. What is the purpose of a 'Red X' system in military-adapted maintenance practices used in some civilian MRO environments?

    Answer: To flag a safety-of-flight discrepancy that grounds the aircraft until corrected

    A Red X signifies a grounding discrepancy that must be corrected and signed off before the aircraft is airworthy.

  7. When an aircraft alteration requires structural analysis beyond standard practices, the mechanic should obtain approved data from which source?

    Answer: A DER (Designated Engineering Representative) or the FAA

    A Designated Engineering Representative (DER) or the FAA provides approved engineering data for alterations that exceed standard maintenance handbook guidance.
