How a hidden Boeing engine flaw ended in a crash that killed 15

• A UPS plane crashed last fall at Louisville’s Muhammad Ali International Airport, resulting in the deaths of three pilots and 12 people on the ground, with 23 others injured.
• New documents reveal UPS never mandated detailed inspections for a critical flaw that caused an engine to detach, despite Boeing having recommended such inspections years earlier.
• UPS argued that Boeing had incorrectly stated that a failure of the specific engine pylon bearings would not compromise flight safety, which influenced their decision not to require enhanced inspections.
• Officials from both Boeing and the Federal Aviation Administration (FAA) conceded during hearings that they had misunderstood the risks associated with the engine mount flaw before the crash.
• Following the incident, FedEx resumed flying its MD-11s after implementing regular bearing replacements, while UPS chose to retire its entire MD-11 fleet early.
