Investigators say UPS plane that crashed in Kentucky, killing 14, had cracks in engine mount
Federal investigators released dramatic photos Thursday of an engine flying off a doomed UPS cargo plane that crashed two weeks ago in Kentucky, killing 14 people, and said there was evidence of cracks in the left wing’s engine mount.
A series of six photos showed the rear of the engine starting to detach before it flew up and over the wing as flames erupted. The next image shows the wing engulfed by fire as the burning engine flies above it. The last image shows the plane starting to get airborne.
But the MD-11 plane only got 30 feet (9.1 meters) off the ground, the National Transportation Safety Board said, citing the flight data recorder in its first formal but preliminary report about the Nov. 4 disaster in Louisville, Kentucky.
Three pilots on the plane were killed along with 11 more people on the ground near Muhammad Ali International Airport.
The NTSB said the plane was not due yet for a detailed inspection of key engine mount parts that had fractures. It still needed to complete nearly 7,000 more takeoffs and landings. It was last examined in October 2021.
“It appears UPS was conducting this maintenance within the required time frame, but I’m sure the FAA is now going to ponder whether that time frame is adequate,” former federal crash investigator Jeff Guzzetti told The Associated Press after reading the report.
All MD-11s grounded for now
It’s not clear when the cracks started to develop on the 34-year-old plane and whether they could have been missed in that earlier inspection. Another aviation expert, John Cox, described fatigue cracks as “normal wear and tear on an aircraft.”
He said a metal part, like the engine mount that vibrates every time the plane flies, will eventually develop cracks. Cox noted it’s just a question of how often those parts need to be inspected and what maintenance is required.
The NTSB report revealed the first new details since board member Todd Inman briefed reporters on Nov. 7. He said the cockpit voice recorder captured an alarm bell going off about 37 seconds after the UPS crew called for takeoff thrust.
