The pilot flying the commuter aircraft that plunged into a neighborhood in northern NY in February lacked hands-on training with a critical safety system, according to an Associated Press news report.
Also, the pilot reportedly had not passed other flight simulation tests throughout his career.
The lack of hands-on training pertained to a safety system called the stick pusher, which points the nose of the aircraft down if it stalls (goes below the minimum speed needed to stay airborne). The stick pusher lets the plane gain speed to recover from a stall.
When the Bombardier Dash 8-Q400 plane stalled and the safety system put the nose down, the pilot tried to bring it back up, according to the news report. The plane then stalled, rolled over and crashed into a home, killing all 49 people on board and one on the ground.
