An in-flight upset following an autopilot disconnect aboard a Bombardier Challenger 300 seriously injured a cabin attendant near San Francisco on July 27, 2022, according to an NTSB final report released this week. The cause of the disconnect could not be determined, and cockpit voice recorder (CVR) data had been overwritten on a continuous loop.

Registered N557XJ, the Challenger 300 was operating a Part 91 positioning flight from San Francisco International Airport (KSFO) to Page, Arizona (KPGA). The aircraft departed at 12:30 p.m. with two pilots and one cabin attendant on board.
