Unsafe Condition
Failure of a main rotor blade resulting in separation of the blade and subsequent loss of control of the helicopter due to fatigue cracking initiating at the outboard bolt hole and traveling in a chordwise direction, or bond separation between the lower surface root end fitting and doubler.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Within 10 hours time-in-service after the effective date, perform a visual inspection of each blade root end for cracks, paint/sealant cracking, or separation between the lower surface root end fitting and doubler. Repetitive inspections at intervals not exceeding 100 hours TIS must be conducted using Mylar/viewfoil testing if paint/sealant issues are found. Blades with cracks or excessive separation must be replaced before further flight.
