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

This lack of inspection occurred despite a recommendation from Boeing to do so, made years earlier. The details of the crash and the subsequent investigation are outlined in the documents posted by the investigators.

Further information on the incident and UPS's response can be found in the documents and the company's submission to the investigators, available from the source.
