The National Transportation Safety Board (NTSB) has determined that the Feb. 23, 2019, crash of Atlas Air Flight 3591 was most likely caused by the first officer’s failure to respond appropriately to an inadvertent activation of the Boeing 767 cargo jet’s go-around mode on approach to George Bush Intercontinental/Houston Airport (IAH). According to the board's report (PDF), the resultant spatial disorientation led the first officer to put the aircraft into a “steep descent from which the crew did not recover.” The investigation also concluded that the first officer had a history of training performance difficulties along with a “tendency to respond impulsively and inappropriately when faced with an unexpected event during training scenarios.”
