UPS MD-11 engine separation highlights single point of failure
On November 4, 2025, a UPS McDonnell Douglas MD-11 freighter experienced a catastrophic engine separation while operating at Louisville Muhammad Ali International Airport. The incident occurred during a normal taxi and takeoff roll on Runway 17R, resulting in the powerplant physically detaching from the aircraft wing. Investigators are treating the event as a stark reminder of the dangers associated with single points of failure in legacy transport category aircraft. For pilots, this underscores the importance of rigorous preflight inspections and remaining vigilant for abnormal engine indications during takeoff.
