Boeing Knew About Engine Defect on UPS Plane 4 Months Before Crash in Kentucky
A devastating crash in Louisville last November claimed 15 lives, including those of three people on board and 12 others on the ground. The aircraft was a UPS MD-11 cargo plane that experienced engine failure shortly after takeoff, with one wing's engine catching fire and detaching mid-air.
In a recent investigation by the National Transportation Safety Board (NTSB), investigators found evidence that Boeing had warned plane owners about this specific defect four times before - on three separate aircraft. The warning was issued in February 2011 and related to "spherical bearing race" assemblies, which secure engines to wings. However, Boeing did not consider this a flight safety issue and only recommended routine inspections every 60 months.
The investigation revealed that these warnings were not thoroughly reviewed or addressed by UPS, the aircraft's owner. The NTSB report stated that the cracks found in the engine mount parts had not been spotted during the plane's most recent maintenance inspection. In fact, the last time the engine mount parts were closely examined was over seven years ago, with the next scheduled inspection due around 7,000 flights later.
Boeing officials have declined to comment on these findings, stating that they continue to support the NTSB investigation. UPS has also been tight-lipped about the incident, citing ongoing litigation.
The crash shares similarities with a notorious 1979 American Airlines DC-10 crash in Chicago, where a maintenance crew's mistake led to a global grounding of the fleet. The case raises questions about how airlines like UPS handled maintenance issues and whether they did enough to address safety concerns.
As the investigation into this tragedy continues, families of those affected are left to wonder why more was not done to prevent such a disaster from occurring in the first place.
