NTSB Hearing On 2025 UPS Louisville MD-11 Crash Details Metal Fatigue And Boeing Warning
The National Transportation Safety Board on Tuesday questioned UPS, Boeing and other aviation officials and released new video showing an engine detach during takeoff in the Louisville crash that killed 15.[1]
Investigators said metal fatigue led to the failure of a component attaching the left engine to the wing, causing the engine to separate during takeoff.[1] Investigators also said the Flight 2976 crew had been reassigned to the accident MD-11F after their original MD-11 was pulled from service for a fuel leak.[1] The NTSB is probing whether maintenance lapses or safety failures, and UPS' response to a 2011 Boeing notice about MD-11 structural issues, contributed to the accident.[1] The crash killed all three pilots and 12 people on the ground, and it injured nearly two dozen others.[1]
On November 4, 2025, UPS Flight 2976's MD-11F lost its left engine during takeoff from Louisville International Airport and crashed into a nearby business complex, killing 15.[1] The Federal Aviation Administration grounded MD-11 aircraft after the crash; UPS has retired MD-11s while FedEx has begun returning MD-11s to service after Boeing-recommended, FAA-approved repairs.[1] UPS issued a statement on May 19 saying, "Our focus remains on supporting the investigation and honoring those affected by this tragedy."

Early coverage emphasized NTSB questioning of Boeing and UPS about possible safety failures without naming a technical cause.[2] Later reporting and NTSB disclosures focused on metal fatigue, the engine separation video, and questions about whether UPS acted after a 2011 Boeing notice, a shift driven by CBS reporting at the hearing.[1]
