Probable cause: The pilot’s exceedance of the airplane’s critical angle of attack during an attempted go-around, which resulted in an aerodynamic stall.
Unfamiliarity with airplane fatal for two
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
Hard landing results from trying to avoid flock of birds
Probable cause: The pilot’s abrupt maneuver to avoid birds during short final approach, which resulted in a hard, bounced landing.
Spin training flight ends in fatal accident
Probable cause: The failure of the pilots to apply prompt and/or correct flight control inputs to adequately recover from the intentional aerodynamic spin.
Failure to properly deice plane leads to accident on takeoff
Probable cause: The pilot’s failure to properly deice the airplane before takeoff, which resulted in an aerodynamic stall during the initial climb.
Maintenance error leads to Piper crash
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.
Currency flight goes awry
Probable cause: The pilot’s failure to maintain an appropriate glidepath to the runway and to use the vertical guidance system.
Maintenance error leads to fatal accident
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
Piper pilot loses control on snow
Probable cause: The pilot’s failure to maintain directional control while landing in flat light conditions on a hard-packed snow-covered landing area.
