Maneuver and Loss of Control
The pilot and a pilot-rated passenger departed and climbed to 6,500 feet mean sea level, where they performed an aileron roll. Subsequently, the pilot returned to the airport and entered the landing traffic pattern. After turning onto the base leg, the pilot decided he needed more room between the airplane and the end of the runway, so he turned away from the runway. During this maneuver, the airplane buffeted, and aileron and elevator control were lost. The pilot reported applying full engine power, but the airplane stalled and crashed into the ground.
Witness Observations
Two witnesses observed the airplane on the base leg and while maneuvering during its last few seconds of flight. Both witnesses estimated that the airplane was not flying higher than 300 feet above ground level. They reported seeing the aircraft turn away from the landing runway, enter a steep left bank turn, and then turn back toward the runway. During the turn, the bank angle increased to at least 80 degrees, according to both witnesses. The airplane appeared to stall and then descend into the terrain.
Passenger Statement and Conditions
The pilot-rated passenger stated that the pilot had pushed the aircraft beyond its capabilities. The temperature at the time was about 105 degrees Fahrenheit, resulting in a density altitude of about 6,000 feet.
