Unsafe Condition
Skinny cast yoke on CF6-80C2 forward engine mounts does not meet Design Service Goal (DSG) requirements, potentially leading to deterioration of structural integrity and possible separation of the engine from the engine mount during flight.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Inspect to determine part number of forward engine mounting yoke. If skinny cast yoke (P/N 9383M43G08, 9383M43G09, 9383M43G10, or 9383M43G11) is found, perform a detailed inspection for rupture. If ruptured, repair before further flight. If not ruptured, replace with forged yoke within 7,000 flight cycles after AD effective date. Report findings to Airbus.
