Which of the following is a condition that would require an Airworthiness Directive (AD) to be complied with before flight?
Answer: An expired ELT battery
An expired ELT battery is typically addressed by an AD requiring compliance; ADs are mandatory and must be complied with to maintain airworthiness.
When performing an inspection using a borescope, what is the primary advantage over direct visual inspection?
Answer: It allows internal inspection of areas inaccessible without disassembly
A borescope allows visual examination of enclosed or inaccessible spaces such as fuel tanks, wing interiors, and structural tubes without disassembly.
What is the significance of an asterisk (*) notation on an FAA-approved aircraft weight and balance report?
Answer: It denotes items that are included in the licensed empty weight
Items marked with an asterisk on a weight and balance report are typically included in the licensed empty weight calculation.
During an annual inspection, a mechanic finds that a required placard is missing from the cockpit. What action must be taken before returning the aircraft to service?
Answer: Replace or reproduce the placard with the correct information per the TCDS or AFM
Required placards are part of the type design; a missing placard must be replaced with one that meets the approved data before returning the aircraft to service.
An inspection reveals that a wing attachment bolt has been replaced with one of the same diameter but made of a lower-grade material. This condition represents:
Answer: A major structural discrepancy and a type design non-conformity
Using a lower-grade bolt in a structural joint deviates from the approved type design and compromises structural integrity, constituting a major discrepancy.
When inspecting a pressurized fuselage for fatigue cracks, which location is considered highest risk and should receive the most attention?
Answer: Around window and door cutouts and skin lap joints
Stress concentrations at window frames, door cutouts, and skin lap joints make these areas the most fatigue-critical zones in a pressurized fuselage.
A mechanic discovers an Airworthiness Directive that applies to the aircraft being inspected but has never been complied with. The AD has a compliance time that has already passed. What must happen?
Answer: Compliance must be accomplished before the aircraft is returned to service
An overdue mandatory AD means the aircraft is not airworthy; compliance must be completed before the aircraft is approved for return to service.
