The pilot’s failure to maintain adequate airspeed while maneuvering during an attempted go-around, which resulted in an exceedance of the airplane's critical angle of attack and an aerodynamic stall at low altitude. Contributing to the accident, was the pilot’s decision to perform an approach to a short runway at an excessive airspeed and his late decision to perform a go-around, which resulted in a slow climb at a reduced safe margin above stall airspeed.
