Crash investigators have released new documents regarding a UPS plane crash. The documents reveal that UPS did not require detailed inspections of a specific part that ultimately failed, leading to an engine flying off the plane.

This lack of inspection occurred despite a recommendation from Boeing to do so, which was made years prior to the crash. UPS has submitted its own response to the crash investigators, but details of this submission are not specified.

Further information on the crash and the investigation's findings can be found through the crash investigators' postings and other sources, including KPRC 2 and Click2Houston.
