Key Takeaways:

The widow of pilot Dana Justin Diamond has filed a lawsuit against Boeing, General Electric, and maintenance provider VT San Antonio Aerospace, alleging wrongful death and negligence.
The suit stems from a November 4, 2025, UPS MD-11 crash in Louisville, Kentucky, where the aircraft's left engine separated shortly after takeoff, killing three crewmembers and 12 people on the ground.
Attorneys argue that the engine separation was a direct failure by the companies responsible for building and maintaining the aircraft, not an accident.
Following the crash, the FAA banned the MD-11 fleet until inspections are completed, and UPS has subsequently retired its entire MD-11 fleet.
