  1. Under 14 CFR Part 43, who is authorized to approve an aircraft for return to service after a 100-hour inspection?

    Answer: A certificated mechanic holding an Airframe and Powerplant rating

    14 CFR Part 43.7 authorizes a certificated A&P mechanic to approve an aircraft for return to service after a 100-hour inspection.

  2. When using a torque wrench, in which direction should you apply force relative to the wrench handle to get an accurate reading?

    Answer: In-line with the handle from the pivot point

    Torque wrenches are calibrated for force applied in-line with the handle at the grip point; off-axis force produces inaccurate readings.

  3. Which document must be issued before a major repair or major alteration can be performed on a certificated aircraft?

    Answer: A Supplemental Type Certificate

    A Supplemental Type Certificate (STC) approves the design data for a major alteration; FAA Form 337 records the completed work.

  4. What action is required when a mechanic discovers a defect that could endanger the aircraft but is outside the scope of their work order?

    Answer: Notify the aircraft owner or operator of the unsafe condition

    14 CFR 43.13 requires the mechanic to notify the owner or operator of any unsafe condition found during maintenance.

  5. Lockwire installed on left-hand threaded fasteners should wrap in which direction so that tightening tension is maintained?

    Answer: Counter-clockwise when viewed from the bolt head

    On left-hand threaded fasteners the lockwire must pull counter-clockwise (when viewed from the head) to resist loosening.

  6. A mechanic discovers an Airworthiness Directive (AD) applies to a component they are about to install. What is the correct course of action?

    Answer: Comply with the AD before installing, or install an AD-compliant part

    AD compliance is mandatory; the mechanic must comply with the AD requirements before installing the affected component.

  7. Which OSHA standard primarily governs hazard communication (HazCom) and Safety Data Sheets in an aircraft maintenance shop?
