Federal investigators recently shared striking images of an engine detaching from a UPS cargo plane that crashed in Kentucky two weeks ago, resulting in 14 fatalities. The National Transportation Safety Board (NTSB) highlighted cracks found in the left wing’s engine mount as a potential cause.
The MD-11 aircraft only managed to ascend about 30 feet off the ground before the disaster occurred. The NTSB noted that the plane had not been scheduled for a detailed inspection of these critical parts until it completed nearly 7,000 more takeoffs and landings. The last inspection took place in October 2021.
Jeff Guzzetti, a former federal crash investigator, pointed out that while UPS followed maintenance guidelines, the FAA might need to reconsider the adequacy of those time frames for inspections. Balancing safety and operational demands is crucial, especially as some aviation experts, like John Cox, highlight that metal parts naturally develop fatigue cracks over time.
The cockpit voice recorder revealed an alarm sounded shortly after the crew requested to take off. Sean Garber, whose auto salvage yard near the airport was directly affected, expressed concern over the human error aspect of this tragedy, contrasting it with natural disaster incidents.
In response to the crash, the FAA grounded all MD-11 aircraft used by UPS, FedEx, and others for inspections. This step impacts around 9% of UPS’s fleet and 4% of FedEx’s. Cox anticipates difficult decisions ahead for these carriers, especially since they were already planning to phase out these planes in the coming years.
UPS Airlines President Bill Moore stressed the company’s commitment to working with investigators to uncover the crash’s root cause. The timeline for returning the fleet to service remains uncertain.
Interestingly, the NTSB report echoed a similar incident from 1979 involving a DC-10, the predecessor to the MD-11, which resulted in a tragic loss of 273 lives. This history underlines the importance of reassessing maintenance practices and possibly integrating advanced technologies for inspecting aircraft structures.
Former federal crash investigator Alan Diehl emphasized the need to reevaluate maintenance schedules for older models, advocating for the use of high-tech inspection methods. He emphasized that understanding potential weaknesses in aircraft design is crucial.
As Louisville continues to mourn, community events, like concerts from the Louisville Orchestra, aim to provide solace during this difficult time. Music remains a powerful tool for healing and connection.
In aviation safety discussions, the emphasis on maintenance and technology will likely grow, especially as older fleets remain in service. Overall, this tragedy has raised numerous questions about regulations and practices in the aviation industry.
