The crash of a United Parcel Service MD-11 cargo jet last November near Louisville, Kentucky, tragically claimed the lives of all three crewmembers on board, in addition to those of 12 people on the bottom. The Federal Aviation Administration acted quickly, grounding all MD-11s within the U.S., while the National Transportation Safety Board launched an investigation that concluded in its initial report that a cracked left engine mount was guilty. The crash itself was already tragic enough, but following a brand new NTSB hearing on the crash, the Guardian reports that cracks in that engine mount had already been discovered before the crash but weren’t reported.
While the NTSB has already released its initial report, the board released a further 2,000 pages of documents to coincide with the hearing and claimed the plane that ultimately crashed had been brought in to switch a distinct plane that couldn’t fly until UPS fixed an fuel leak. The NTSB also revealed evidence that Boeing knew some MD-11s were experiencing cracked engine mounts:
Between the crash and the NTSB hearing, the board said that a cracked part on the doomed jet was flagged in a Boeing 2011 report which said there had previously been 4 such failures on three different airplanes.
The NTSB said its investigation had found fatigue cracks in a support structure on the left pylon that connects to the wing and the plane’s engine referred to as the bearing race.
The agency also said there have been a series of reports of cracks in race parts on MD-11 planes within the prior decade.
More to return
The NTSB’s hearing is scheduled to proceed for a second day, so we likely still have quite a bit to learn concerning the crash, which also injured 23 others when an auto parts recycling center caught fire. But based on Kentucky’s WDRB, investigators “found records of 10 previous flaws in the identical key parts that help secure engines to wings of other similar planes, and most of them were never reported to the FAA.” You need to think giant corporations would care about those sorts of things, but apparently not.
Why those flaws were largely unreported and why the federal government didn’t step in earlier were reportedly to 2 fundamental focuses of the day. In line with representatives of each UPS and the FAA, the reports that were submitted were too vague to completely understand the scope of the difficulty or the risks involved in the event that they did not take motion.
Within the video above, you may see the NTSB’s explanation of exactly which part failed and the way. In line with UPS Senior Director of Engineering David Springer, Boeing’s service reports made the cracks within the engine mounts that it had found “sound almost benign,” adding, “I feel if we’d have known that at UPS, I feel we’d have asked loads of different questions through the years.” After all, UPS also has loads of reasons to do its best to make sure Boeing takes nearly all of the blame here, since WDRB also reports the board presented evidence that the delivery service must have caught the issue before 15 people died:
Examining the wreckage, investigators found cracks in a few of the parts that held the engine to the wing, the NTSB said. Those cracks hadn’t been caught in regular maintenance, which raised questions on the adequacy of the upkeep schedule. The last time those key engine mount parts were examined closely was in October 2021, and the plane wasn’t due for one more detailed inspection for roughly 7,000 more takeoffs and landings.
While the NTSB probably won’t release its final report until next yr, hopefully, day two of the hearing not less than paint a clearer picture of how a UPS plane crashed just after takeoff.
