Unsafe Condition

The unsafe condition, if not corrected, could result in separation of the NLG fork with consequent reduced control on landing. If the NLG fork separates on an unimproved surface, the risk of the NLG digging in and the airplane overturning on the ground increases.

AI-generated summary from the source AD text. Verify against the official source before acting.

Required Actions

Inspect the airplane to determine if an NLG fork P/N 100-410-7001 (type A) or an NLG fork P/N 100-410-7013 (type B) is installed. If a type A fork is installed, do a fluorescent penetrant, dye penetrant, or open-hole eddy current inspection of the NLG fork for cracks. If any cracks are found, replace the NLG fork with a type B fork. Inspect the shimmy damper bracket for looseness and the shimmy damper system for damaged components. If a loose shimmy damper bracket is found, rework it with interference-fit bolts. If any other damaged components are found, replace them. Alternatively, replace the NLG fork with a type B fork to terminate the inspection requirements.
