NTSB: UPS MD-11F engine pylon failure tied to fatigue cracks and 10 prior ignored bearing alerts At an NTSB hearing, investigators said the left engine/pylon separation on a UPS MD-11F stemmed from fatigue cracking in the pylon bearing supports—a problem reported as far back as 2002. The cracked part had fractured 10 times previously, with questions raised over inspection and reporting by the FAA, Boeing and UPS maintenance personnel.
