Engine failure suspected as UPS cargo jet crashes near Louisville, nine dead
Investigators probe a deadly UPS cargo jet crash in Louisville, exploring engine failure and what it means for air safety.
A UPS cargo jet crashed shortly after takeoff from Louisville, killing nine people and forcing a halt to operations at the Worldport hub as authorities investigate the cause. The MD-11, bound for Hawaii, erupted in flames and spread a massive blaze across a wide area, with investigators later recovering the flight’s black boxes to piece together what happened. Crews and first responders worked through the night to secure the scene and assess damage to surrounding infrastructure and communities.
Aviation experts have pointed to engine issues as a possible trigger. One analyst noted that the left engine reportedly detached and caught fire moments after takeoff, while another analysis focused on how an initial engine problem could cascade into a loss of thrust across all engines. The three-engine layout of the MD-11 means that losing two engines significantly reduces power and makes climb-out extremely challenging, raising questions about weight, speed, and emergency response times in the critical early minutes after takeoff.
Marco Chan, a senior lecturer in aviation operations, explained that footage appeared to show the third engine damaged, emitting a puff of smoke before winding down. “The upper engine that expelled a puff of smoke appears to wind down almost immediately afterwards,” he said. “That left only the right engine producing thrust, creating a severe power imbalance and leaving the aircraft unable to gain height.” He added, “Losing two engines during take-off leaves the aircraft with only a third of its power and little chance of maintaining flight, especially at maximum take-off weight.”
The crash halted UPS Worldport operations and prompted a pause in some deliveries, with the company noting that shipments could be delayed as investigators piece together the sequence of events. Officials stressed that a thorough, data-driven inquiry was underway, focusing on whether a mechanical failure, maintenance issue, or other factor contributed to the tragedy. Investigators have said the investigation could take weeks, but early findings will shape safety guidelines and operational practices for cargo aviation alike.
