✍️ Sample IA Questions & Answers
1. Which regulation specifically lists fuel filters and strainers as items that must be inspected during an annual inspection?
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.
2. What does an IA look for when inspecting aircraft antenna mounts during an annual?
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.
3. What is the IA's role in verifying that aircraft equipment matches the aircraft's current equipment list?
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.
4. What does an IA check regarding propeller tracking during an annual inspection?
Propeller tracking verifies that all blades rotate in essentially the same plane; excessive deviation indicates a bent blade or flange misalignment.
5. What is the IA's liability if they approve an aircraft for return to service and a subsequent accident reveals an undetected defect?
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.
6. During an annual inspection, the IA checks the magneto-to-engine timing. What is the risk of advanced timing?
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.
