NTSB Report *Released* UPS Cargo Crash Flight 2976
Quick Overview
The NTSB preliminary report on the deadly UPS plane crash in Louisville revealed that the failure was caused by the catastrophic detachment of the left engine and pylon assembly shortly after takeoff, which was attributed to damage to the spherical bearing within the pylon aft mount due to a lack of required maintenance inspections (SDI tasks).
Key Points: The UPS flight 2976 crash on November 4, 2025, in Louisville, KY, resulted in 14 fatalities (3 crew, 11 on the ground) and 23 serious injuries. The left (No. 1) engine and pylon assembly separated from the wing shortly after rotation, igniting a fire on the left engine, which continued until ground impact. Wreckage examination showed the forward and aft lugs on the left pylon aft mount were fractured near the 2 o'clock and 9 o'clock positions, respectively. The fracture surfaces on the forward lug showed only overstress failure with no indications of fatigue cracking, while the aft lug showed evidence of fatigue cracks in addition to overstress failure. The left wing clevis, aft mount spherical bearing, and associated hardware were found with a portion of the left wing, showing the spherical bearing outer race had fractured circumferentially. The accident aircraft (N259UP) had accumulated 92,992 hours and 21,043 cycles, and records showed two Special Detailed Inspection (SDI) tasks for the pylon/clevis support were not accomplished. In response, UPS grounded its MD-11 fleet on November 7, 2025, following an FAA Emergency Airworthiness Directive.
Context: This video analyzes the preliminary report released by the National Transportation Safety Board (NTSB) concerning the crash of United Parcel Service (UPS) flight 2976, a McDonnell Douglas MD-11F cargo aircraft, which occurred on November 4, 2025, shortly after takeoff from Louisville Muhammad Ali International Airport (SDF). The analysis focuses heavily on the maintenance history and the physical evidence from the failed left engine pylon attachment, drawing parallels to the 1979 American Airlines Flight 191 crash involving a similar structural failure.
