UPS permanently retires MD-11 cargo jets after Louisville crash, accelerating fleet modernization and network adjustments
UPS ends MD-11 operations as federal investigators continue probing November crash near Worldport
UPS has permanently retired its McDonnell Douglas MD-11 cargo aircraft, ending operation of the three‑engine jet in the company’s air network after a fatal crash near Louisville and a subsequent safety-driven grounding of the type.
The decision follows the Nov. 4, 2025 crash of a UPS-operated MD-11 shortly after takeoff from Louisville Muhammad Ali International Airport, adjacent to UPS Worldport, the company’s primary air hub. The aircraft was operating a domestic cargo flight bound for Honolulu when it lost an engine during the takeoff sequence and went down in an industrial area near the airport. The crash killed the three crewmembers on board and caused fatalities and injuries on the ground. The investigation remains ongoing.
What is known so far about the crash
Early investigative findings have focused on the left engine and its attachment to the wing. Investigators recovered the aircraft’s recorders, and preliminary evidence indicates an abnormal warning sound in the cockpit soon after takeoff thrust was set. The airplane did not climb normally and impacted structures near the airport perimeter before crashing and burning. Officials have not released a final determination of cause.
Regulatory action and industry response
In the days after the accident, UPS temporarily grounded its MD-11 fleet. Federal regulators then issued emergency actions restricting MD-11 operations until specified inspections and any required corrective actions were completed. The directives extended to related widebody tri-jet and derivative models that share similar nacelle and pylon design considerations.
Other operators of MD-11 freighters in the United States also paused or reduced MD-11 flying during the same period. The MD-11 had largely disappeared from passenger service years earlier, but remained in use in cargo operations.
Why retirement matters for UPS’s air network
UPS previously disclosed that MD-11s represented a single-digit share of its airline fleet and that the company had been evaluating incremental retirements of fully depreciated aircraft as part of normal fleet management. The Louisville accident and subsequent grounding effectively removed the MD-11 from revenue service, pushing the carrier toward an accelerated transition to other freighter types already central to its network.
UPS has said it will continue to operate its global air system through contingency planning and network adjustments. The permanent MD-11 retirement is expected to shift flying to remaining widebody and medium-widebody freighters, along with leased and charter capacity where needed, while investigators continue to examine the mechanical and maintenance factors surrounding the Louisville crash.
The investigation into the Nov. 4, 2025 crash remains active, and final conclusions will depend on further analysis and formal findings.
