Unsafe Condition
Failure of the main landing gear actuating cylinder upper attach bracket due to insufficient hardness (outside Rockwell C39.0 to C43.0 range) and potential cracking at the junction of the grease fitting hole and actuating cylinder attach hole.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Conduct a hardness check on attach brackets (P/N 5641950-1, -2, -501, -502) with 4,000+ hours' time in service within 440 hours after AD effective date, or before reaching 4,440 hours' time in service for brackets with less time. Inspect for cracks using dye penetrant if hardness is out of spec, apply yellow identification stripe if acceptable, replace cracked brackets with compliant parts before further flight.
