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.

Briefing

What Hype is tracking

  • The findings link the MD-11F separation to repeat fatigue cracking and multiple prior failures (10 prior fractures) that were allegedly not acted on, sharpening scrutiny of maintenance inspection, escalation and reporting processes.
  • The hearing’s focus on how FAA, Boeing and UPS handled pylon bearing reports directly affects airworthiness oversight and operator/maintainer compliance requirements for aging freighter fleets.
  • This accident update strengthens the risk picture for remaining MD-11 freighters discussed in UPS MD-11F crash likely spells end for aging MD-11 freighter fleet, informing near-term fleet management decisions.
