Unsafe Condition
Failure of a main rotor blade assembly or main rotor hub lead-lag link assembly, loss of a main rotor blade, and subsequent loss of control of the helicopter due to cracks in the main rotor blade root fittings, lugs, adjacent blade skin, and movement of root fitting bushings.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Within 25 hours time-in-service after the effective date, and every 100 hours thereafter, remove each blade assembly and inspect root fittings, lugs, and bushings for cracks and looseness; apply slippage marks if degraded or missing. Every 25 hours thereafter without removing the blade, visually inspect for cracks and loose bushings. Replace cracked or loose components before further flight.
