Unsafe Condition
Cracks and failure in the nose landing gear retract cylinder rod terminal ends (P/N 404052 or 1005032) due to fatigue.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Inspect rod terminal ends using ultrasonic, magnetic particle, or approved method. Replace cracked parts before flight. Rework uncracked parts (polish, shot peen, cadmium plate, and stamp) to extend inspection intervals. Follow specific inspection intervals based on landing counts.
