NTSB Accidents

Probable cause: The flight instructor’s exceedance of the critical angle of attack during a go-around, which resulted in an aerodynamic stall/spin. Contributing to the accident was the flight instructor’s failure to familiarize himself with the flight character

Probable cause: The pilot’s abrupt maneuver to avoid birds during short final approach, which resulted in a hard, bounced landing.

Probable cause: The failure of the pilots to apply prompt and/or correct flight control inputs to adequately recover from the intentional aerodynamic spin.

Probable cause: The pilot’s failure to properly deice the airplane before takeoff, which resulted in an aerodynamic stall during the initial climb.

Probable cause: Maintenance personnel’s incorrect installation of the No. 3 cylinder’s hydraulic valve tappet plunger, which resulted in a failure of the No. 3 cylinder’s intake valve and the subsequent partial loss of engine power. 

Probable cause: The pilot’s failure to maintain an appropriate glidepath to the runway and to use the vertical guidance system.

Probable cause: The failure of maintenance personnel to ensure that the throttle and fuel metering unit AN “B” nut was secured, which resulted in a total loss of engine power in flight and a subsequent collision with trees while attempting

Probable cause: The pilot’s failure to maintain directional control while landing in flat light conditions on a hard-packed snow-covered landing area.

Probable cause: The student pilot’s inadvertent use of the control yoke to correct for a drift and his subsequent failure to maintain directional control during takeoff.
