Mixed Deck — All IA Topics Flashcards

Which regulation specifically lists fuel filters and strainers as items that must be inspected during an annual inspection?

Answer: 14 CFR Part 43, Appendix D

14 CFR Part 43, Appendix D provides the scope and detail of items to be included in an annual or 100-hour inspection, which includes fuel system components such as filters and strainers.

What does an IA look for when inspecting aircraft antenna mounts during an annual?

Answer: Corrosion at the mount, cracked radomes, loose mounting hardware, and proper bonding to the airframe

Antenna mount inspection focuses on structural security, corrosion at the mount plate, and proper electrical bonding to ensure the antenna functions correctly and doesn't create a structural weak point.

What is the IA's role in verifying that aircraft equipment matches the aircraft's current equipment list?

Answer: The IA must confirm that installed equipment matches the approved equipment list and that additions are approved

The aircraft's equipment list is part of the approved type design; items added or removed must be properly documented, and the IA must verify the aircraft conforms to its approved configuration.

What does an IA check regarding propeller tracking during an annual inspection?

Answer: That each blade tip passes through the same plane of rotation within manufacturer limits

Propeller tracking verifies that all blades rotate in essentially the same plane; excessive deviation indicates a bent blade or flange misalignment.

What is the IA's liability if they approve an aircraft for return to service and a subsequent accident reveals an undetected defect?

Answer: The IA may face FAA certificate action and civil liability if negligence or failure to follow required procedures is demonstrated

An IA who failed to follow required inspection procedures or acted negligently may face FAA enforcement action and civil liability; an IA who followed all applicable standards has a strong defense.

To qualify for an IA, an applicant must have been actively engaged in maintaining certificated aircraft for at least how long?

Answer: 2 years

14 CFR 65.91 requires at least 2 years of active maintenance experience.

What interval applies to the altimeter and static system tests required for IFR operation under 14 CFR 91.411?

Answer: 24 calendar months

Section 91.411 requires the altimeter system and static system test within the preceding 24 calendar months.

Which item is required in a maintenance record entry for an inspection under 14 CFR 43.11?

Answer: Type, extent, and date of inspection and total time in service

Entries must show type, extent, date, total time in service, and signer's certificate information.

An Inspection Authorization expires on:

Answer: March 31 of each odd-numbered year

Under 14 CFR 65.93 an IA expires March 31 of each odd-numbered year unless renewed.

During an annual inspection, the IA checks the magneto-to-engine timing. What is the risk of advanced timing?

Answer: Preignition and detonation that can damage pistons and cylinders

Timing that is too far advanced causes the fuel-air charge to ignite before the piston reaches the correct position, leading to preignition and potentially destructive detonation.

Under 14 CFR 91.213(d) for aircraft without an MEL, an inoperative instrument or equipment that is not required may be deferred if it is:

Answer: Removed or deactivated and placarded "Inoperative"

The equipment must be removed or deactivated and placarded inoperative, and a determination made that it does not create a hazard.

An owner must keep a copy of Form 337 for which work, per 14 CFR 91.417(a)(2)(vi)?

Answer: Each major alteration to the airframe and currently installed engines, rotors, propellers, and appliances

Section 91.417(a)(2)(vi) requires retaining Form 337 copies for major alterations to the airframe and currently installed components.

What does a Special Flight Permit (ferry permit) allow an unairworthy aircraft to do?

Answer: Fly from one location to a maintenance facility for repairs, or to a point of storage or demolition

A Special Flight Permit allows an aircraft that cannot meet standard airworthiness requirements to make limited flights for specific purposes like ferrying to a repair station.

A coin-tap test is primarily used to detect:

Answer: Delamination or disbonds in bonded or composite structure

A change from a sharp ring to a dull thud indicates a delamination or disbond.

Eddy current inspection is especially well suited to finding:

Answer: Cracks around fastener holes in conductive structure

Eddy current detects surface and near-surface cracks in electrically conductive materials, such as around rivet holes.

Before applying for an IA, how long must an applicant have held both airframe and powerplant ratings?

Answer: At least 3 years

14 CFR 65.91 requires the mechanic certificate with both ratings to have been held for at least 3 years.

What is the purpose of a discrepancy report?

Answer: Documents inspection findings

The purpose of a discrepancy report is to formally document all defects, unairworthy conditions, or non-conformities discovered during an aircraft inspection. It serves as a comprehensive list of items that require corrective action and repair before the aircraft can be approved for return to service, ensuring all issues are addressed.

After a major repair is approved for return to service, how must the completed FAA Form 337 be handled?

Answer: Copy to the aircraft owner and a copy forwarded to the FAA within 48 hours

Appendix B of part 43 requires one copy to the owner and one forwarded to the FAA Aircraft Registration Branch within 48 hours.

What is the role of an IA in determining airworthiness?

Answer: Determines compliance and safe condition

The primary role of an Inspection Authorization (IA) holder in determining airworthiness is to meticulously inspect an aircraft to determine its compliance with all applicable regulations and ensure it is in a safe condition for flight. IAs are authorized to perform annual inspections and approve major repairs and alterations, acting as a critical safeguard for aviation safety.

During an annual inspection of a reciprocating engine, which component is checked for correct torque, safety, and security?

Answer: Engine mount bolts, exhaust system, and all accessory attachment hardware

The annual inspection requires checking all engine hardware including mounts, exhaust connections, and accessory attachments for proper torque and security.
