What is direct damage caused by lightning strikes?
A. Direct damage is defined as metallic structures which are burned, melted, or show signs of metal distortion and non-metallic structures which are burned, punctured, or delaminated.
B. Direct damage occurs when lightning strikes cause disruption to electrical systems, leading to system failure.

What is Phase 1 of the inspection after a hard landing or overweight landing?
A. A detailed structural repair is conducted.
B. It is an inspection phase.
C. The aircraft is taken out of service for an extended period.
B. It is an inspection phase.
What occurs in Phase 2 of the inspection after a hard landing or overweight landing?
A. No action is taken unless further issues arise.
B. Phase 2 occurs if damage is present.
C. The aircraft is grounded for a full overhaul.
B. Phase 2 occurs if damage is present.
What happens if the aircraft skidded or overran the prepared surface during landing?
A. It is considered a high drag/side-load landing.
B. It is a normal landing and no checks are needed.
C. The aircraft is grounded permanently.
A. It is considered a high drag/side-load landing.
What occurs if the aircraft made a landing short of the prepared surface?
A. It is classified as a high drag/side-load landing.
B. The landing is considered normal, and no inspection is needed.
C. The aircraft is immediately repaired.

What happens if two or more tires were blown during landing?
A. It is considered a high drag/side-load landing.
B. The aircraft continues as normal without any issues.
C. The tires are replaced without further inspection.
A. It is considered a high drag/side-load landing.
What does it mean if the aircraft skidded on the runway sufficiently to make you think damage occurred?
A. It is classified as a high drag/side-load landing.
B. It is a normal landing with no issues.
