Old engine-mount flaw flagged by Boeing years before UPS crash, NTSB reveals

The NTSB’s update on the Kentucky UPS MD-11F crash shows cracks in the engine‑mounting assembly. Boeing had identified this flaw on similar aircraft about 15 years ago and, in a 2011 service letter, told operators to perform a general visual inspection every five years and consider a revised bearing assembly—though Boeing said the issue did not pose a safety-of-flight risk. Investigators stress the engine attachment is critical and fatigue may have been involved, but the final cause of the crash has not yet been determined.

NTSB flags long-known engine-mount issue behind UPS crash

The NTSB says Boeing noted four prior failures of the MD-11’s engine-mount bearing race in 2011 but did not classify it as a safety-of-flight issue or require repairs; investigators linked the Louisville UPS crash to cracked engine-mount parts and ongoing maintenance questions on older airframes, with a final determination pending and echoes of a 1979 DC-10 disaster.

NTSB: Boeing Knew of Recurrent Engine-Mount Flaws Before UPS Louisville Crash

The NTSB says a recurring crack in the left-engine mounting on a UPS cargo plane that crashed in Louisville may have contributed to the disaster; Boeing had previously said such fractures would not affect flight safety, and the same flaw has appeared in at least four other instances on three airplanes, though investigators have not yet determined a final cause.
