Unsafe Condition

Fatigue failure of the bolts that secure the transmission rear support fittings to the helicopter, which could lead to loss of control.

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

Required Actions

Visually inspect each main transmission support fitting attachment bolt (part numbers NAS625-14 and NAS625-18) for a fracture, crack, or looseness within 5 hours time-in-service (TIS), and then at intervals not exceeding 10 hours TIS until a torque inspection is completed. If a fracture or crack is found, replace all 4 bolts in the fitting before further flight. If looseness is detected, inspect all 16 bolts to verify torque is between 11.3-15.8 Nm (100-140 inch-pounds). If torque is outside this range, replace all 4 bolts in the fitting before further flight. Complete a torque inspection of each bolt within 25 hours TIS.
