The wife of a pilot killed in last November's crash of a UPS cargo plane near Louisville's airport has filed a lawsuit against Boeing, General Electric, and a maintenance provider. The complaint alleges that the aircraft's left engine and pylon separated from the wing shortly after takeoff, leading to a fire and subsequent crash that killed all three crew members and 12 individuals on the ground. The lawsuit claims the incident was not an accident, but a failure by the companies responsible for building and maintaining the aircraft.

Why it matters

This case highlights ongoing concerns about aircraft safety and the responsibility of manufacturers and maintenance providers when fatal crashes occur. The lawsuit seeks to uncover the causes of the crash and push for changes to prevent similar tragedies in the future.

The details

The aircraft had recently undergone maintenance work performed by VT San Antonio Aerospace in the weeks prior to the crash. Flight data shows the aircraft failed to reach an altitude of over 100 feet in the 37 seconds it was airborne before crashing into warehouses and other buildings.
