Boeing Aware of Structural Flaw in Aircraft Part Linked to Kentucky Crash, NTSB Reports

An investigation into a recent cargo plane crash in Kentucky has uncovered that Boeing was aware of a structural flaw in an engine mounting component years before the incident. The MD-11F aircraft operated by UPS crashed after an engine separated from the wing during takeoff, resulting in the deaths of 15 individuals. The U.S. National Transportation Safety Board (NTSB) has detailed in an update report that cracks in the engine attachment had been previously identified on other aircraft. Despite this, Boeing concluded at the time that such issues "would not result in a safety of flight condition." The MD-11, a model originally produced by McDonnell Douglas before Boeing's acquisition in 1997, remains in service with continued parts and support. The latest findings indicate fatigue-related fractures in a critical bearing, affecting safety and maintenance protocols. Boeing had issued a service letter in 2011 advising inspections of the part every five years, yet the same issues persisted. Aviation safety expert Tim Atkinson emphasized the gravity of the issue, noting the role of the engine attachment as a load-bearing component crucial to aircraft safety. Critics have questioned Boeing's internal processes, especially following previous controversies such as software flaws in the 737 Max that led to tragic accidents. Boeing issued a statement supporting the ongoing investigation and expressing condolences to the families affected. The final cause of the Kentucky crash remains under review, with the NTSB unlikely to issue conclusions until its comprehensive report is published.
