Investigations into a deadly UPS cargo plane crash in Kentucky have revealed significant flaws linked to the aircraft’s design. The MD-11F freighter crashed in November while attempting to take off from Louisville, killing 15 people, including three crew members and 12 individuals on the ground.
Boeing’s Awareness of Flaw in Part Tied to UPS Crash
The crash occurred when one of the plane’s engines separated from the wing shortly after takeoff, causing it to lose control and crash into an industrial area. In a recent report, the U.S. National Transportation Safety Board (NTSB) disclosed that cracks had been previously identified in the engine mounting assembly of similar planes by Boeing as far back as 15 years prior.
Background on the MD-11 and Previous Findings
The MD-11 aircraft, originally produced by McDonnell Douglas, has faced scrutiny due to its age and design. Boeing acquired McDonnell Douglas in 1997, and the last MD-11 was produced in 2001. Although production has ceased, Boeing continues to provide parts and support for these aircraft.
- Boeing identified the engine attachment flaw on four occasions affecting three different aircraft.
- In 2011, a service letter was issued recommending inspections be performed every five years.
- The NTSB reported cracking and fatigue in crucial bearing components linked to the assembly.
Expert Opinions and Industry Concerns
Tim Atkinson, an aviation safety consultant and former investigator, expressed alarm over the NTSB’s findings. He emphasized the critical nature of the structural components involved and questioned Boeing’s prior conclusion that failures in these parts would not jeopardize safety.
Boeing has faced mounting criticism over its safety practices, particularly following incidents involving its 737 Max aircraft. Issues with design and quality control have raised questions about the company’s commitment to safety.
In response to the ongoing investigation, Boeing stated its support for the NTSB’s efforts and expressed condolences to the families of those affected by the tragedy. The NTSB continues its investigation, with no definitive conclusions released yet as it works toward a final report.
