On May 5, 2017, an Air Cargo Carriers Short 330, subcontracted by UPS and operating as Air Cargo Carriers Flight 1260, crashed after suffering a hard landing at Yeager Airport. Both the captain and first officer were killed in the accident. Early reports state that the left wing made contact with the surface of Runway 5, separated from the fuselage, and the aircraft cartwheeled left off the runway and down a heavily wooded hillside. The National Transportation Safety Board cited in its final report the causes of "the flight crew's improper decision to conduct a circling approach contrary to the operator's standard operating procedures (SOP) and the captain's excessive descent rate and maneuvering during the approach, which led to inadvertent, uncontrolled contact with the ground. Contributing to the accident was the operator's lack of a formal safety and oversight program to assess hazards and compliance with SOPs and to monitor pilots with previous performance issues."
