Probable Cause: The pilot’s failure to maintain sufficient airspeed following a loss of engine power, which resulted in an inadvertent aerodynamic stall/spin at low altitude.
Aerodynamic Stall
Pilot Loses Control During Attempted Go-Around
Probable Cause: The pilot’s failure to maintain aircraft control and his exceedance of the airplane’s critical angle of attack, which resulted in an aerodynamic stall and spin during an attempted go-around.
Biplane Pilot Loses Control During Return to the Airport
Probable Cause: The pilot’s exceedance of the airplane’s critical angle of attack, resulting in an aerodynamic stall and loss of control.
