UPS and FedEx Temporarily Suspend MD-11 Operations Following Fatal Crash in Kentucky

In a cautious move, both UPS and FedEx have decided to ground their McDonnell Douglas MD-11 aircraft fleets after a deadly incident occurred at the UPS Worldport facility in Louisville, Kentucky.

The tragic accident, which took place on a Tuesday, resulted in the loss of 14 lives, including the three pilots in charge of the MD-11 destined for Honolulu. According to Todd Inman from the National Transportation Safety Board, the aircraft involved was initially a 1991 McDonnell Douglas plane that had been converted to an MD-11 Freighter model.

The MD-11 models constitute approximately 9% of UPS's air fleet and 4% of FedEx's, as stated by the companies. The proactive decision to ground these planes follows the manufacturer’s recommendation, with UPS expressing that the well-being of their employees and the surrounding communities is of utmost importance.

FedEx also shared that their decision to suspend MD-11 operations stems from pursuing a detailed safety audit aligned with the manufacturer's suggestion.

Despite inquiries made, Boeing, which acquired McDonnell Douglas in 1997, has yet to provide detailed reasoning for this recommendation. Meanwhile, Inman has noted that Boeing has taken over certain responsibilities concerning the investigation.

Flight history indicates that the UPS MD-11 remained grounded for maintenance in San Antonio, Texas, for over a month before mid-October, although specifics on the maintenance performed are still unknown.

Western Global Airlines remains the only other U.S. cargo airline operating MD-11s, housing 16 in their fleet with 12 already stored away, according to Cirium, an aviation analytics company.

Back in 1998, Boeing had announced a gradual phase-out of MD-11 production, planning to complete final orders by 2000.

The ill-fated UPS plane was on the cusp of becoming airborne when calamity struck, forever altering the lives of many. Within a tense 25-second struggle, alarms sounded, and the MD-11—leaving a trail of fiery destruction as its left wing caught afire—crashed to the ground, carrying with it a substantial amount of jet fuel and thousands of packages.

As of now, the investigation into why alarms went off continues, with Inman explaining that it will take months before the cockpit recording transcripts are available to the public.

Jeff Guzzetti, who formerly investigated crashes for the government, speculates that the warning bell may have indicated an engine fire, occurring at a critical juncture where aborting takeoff safely on the runway was seemingly unfeasible.

Vivid recordings show the plane colliding with buildings and bursting into flames, captured by various devices and providing invaluable perspectives for investigators.

Georgie Dow, an auto parts company CFO, recounted to CBS News how successive explosions unfolded, conveying the intense heat and danger that kept helpers at bay.

As UPS's most significant processing center, the Louisville hub employs over 20,000 individuals, managing 300 flights daily while processing upward of 400,000 packages hourly.

Despite the tragedy, operations resumed on Wednesday evening for UPS, initiating their Next Day Air services, as confirmed by spokesperson Jim Mayer.
