LOUISVILLE (01/14/26) — Boeing warned plane owners in 2011 about a broken part that contributed to a UPS plane crash that killed 15 last year in Louisville but at that point the plane manufacturer didn’t believe it threatened safety. The National Transportation Safety Board said Wednesday that Boeing had documented there were four previous failures of a part that helps secure the MD-11’s engines to the wings on three different planes. A UPS plane crashed in November 2025 shortly after taking off from Muhammad Ali International Airport when the left engine flew off the wing as the plane rolled down the runway. Three pilots on the plane that was headed for Hawaii were killed along with 12 more people on the ground.
