Unsafe Condition

Aft engine mount link failure, which can result in adverse redistribution of the aft engine mount loads and possible aft engine mount system failure.

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

Required Actions

Initial and repetitive visual inspections of both left hand and right hand aft engine mount link assemblies for separations, cracks, and bearing race migration. Cracked or separated parts must be replaced prior to further flight. If spherical bearing race migration is discovered, an additional borescope inspection for cracks is required. If no cracks are found, assemblies have a 75-cycle grace period before replacement. Installation of improved aft engine mount link assemblies terminates the inspections.
