Chilling Images of Deadly UPS Cargo Plane Crash Released

New, harrowing images released by the NTSB provide a frame-by-frame look at the final moments of a UPS cargo plane, Flight 2976, which crashed shortly after takeoff from Louisville Airport, resulting in the deaths of 14 people. The images depict flames erupting from the left wing as the plane leaves the runway, followed by the clear separation of the left engine.

Details of the Crash and Immediate Aftermath

• Engine Failure: The left engine detached from the wing, snapping upward and erupting in flames that quickly spread to the rest of the aircraft.
• Takeoff Aborted: The pilots were unable to abort the takeoff at this critical stage.
• Altitude and Impact: The plane never ascended more than 30 feet off the ground before crashing into a petroleum recycling plant and a scrapyard.
• Fatalities: The crash claimed the lives of three crew members and 11 individuals on the ground.
• Destruction: The trail of destruction left by the crash extended for half a mile.

NTSB Investigation and Findings

The National Transportation Safety Board (NTSB) is leading the investigation into the cause of the crash. Crucial parts of the aircraft were recovered from the scene, with investigators focusing on the pylon, the component that attaches the engine to the wing of the 34-year-old MD11 aircraft.

• Evidence of Fatigue: The NTSB has reported finding evidence of fatigue cracks in the left pylon.
• Overstress Failure: In addition to fatigue, areas of overstress failure were also identified.
• Prior Maintenance: It was noted that the aircraft had undergone maintenance two weeks prior, during which this specific area was supposed to be inspected. However, the report highlights that visual inspection is not always sufficient to detect fine fatigue cracks, often requiring X-ray technology.

Grounding of Aircraft and Similarities to Past Incidents

In response to the findings, the NTSB, Boeing, and the FAA have grounded all MD11, MD10, and DC10 aircraft as they investigate whether this issue is widespread across the fleet.

• Historical Parallel: Investigators have drawn parallels between this disaster and the 1979 crash of American Airlines Flight 191 in Chicago. That incident involved a DC10 that also experienced engine separation shortly after takeoff, leading to the deaths of 273 people.

Timeline for Final Report

A final report from the NTSB regarding the crash investigation is anticipated to be released within 18 to 24 months.

Conclusion

The release of these graphic images underscores the severity of the UPS cargo plane crash in Louisville. The NTSB's investigation is actively pursuing the cause, with initial findings pointing towards fatigue cracks and overstress failure in the engine pylon. The grounding of similar aircraft highlights the potential for a systemic issue, and the comparison to the American Airlines Flight 191 disaster emphasizes the critical importance of understanding and rectifying such mechanical failures to prevent future tragedies.
