US Investigators Find Boeing Knew About Engine Defect on UPS Plane Before Crash in Kentucky
A preliminary report from the National Transportation Safety Board (NTSB) has revealed that Boeing knew about a defective engine part that may have contributed to the fatal crash of a UPS cargo plane in Louisville, Kentucky, last November. The report states that Boeing had previously warned plane owners about the issue, but did not believe it was a significant safety concern and therefore did not require immediate repairs.
The investigation found that the engine part, a spherical bearing race assembly, had failed on four separate occasions on three different aircraft before the UPS MD-11F plane crashed into an industrial complex, killing 15 people. The report notes that Boeing sent a service letter to MD-11 owners in February 2011 advising of the earlier failures, but recommended only regular scrutiny of the part during scheduled inspections, rather than immediate action.
The NTSB has raised questions about how UPS incorporated this information and whether it was sufficient to prevent the crash. The agency's investigation also found that the cracks where the plane's engine connected to its wing were not spotted during the most recent maintenance inspection, highlighting concerns about the reliability of pre-flight checks.
Boeing has faced criticism for its handling of safety issues in the past, including a 1979 accident involving an American Airlines DC-10 that killed all 271 people on board. The incident led to the global grounding of the fleet before it was deemed safe again after repairs were made.
The UPS plane's crash has sparked lawsuits and outrage over the company's decision to keep the MD-11 aircraft in service despite known maintenance problems. Relatives of a woman who died on the ground have claimed that UPS was negligent for continuing to operate the planes with faulty engine components.
As investigators continue to probe the cause of the crash, Boeing remains tight-lipped about its response to the defect and its handling of safety concerns. The company's spokesperson has released a statement expressing condolences to the families affected by the tragedy and supporting the NTSB investigation.
