Accident Overview
A pilot reported a loss of control during a landing approach. The accident occurred when the airplane was on final approach to the runway. The pilot had previously reduced power abeam the intended touchdown point and, during the base leg turn, had the airspeed set at 80 mph with flaps at 50 percent.
Pilot Account
According to the pilot, after continuing the turn to final, he lowered the flaps to the full down position. Immediately thereafter, the left wing dropped down about 60 degrees. The pilot responded by applying full power and was able to level the wings. However, he was unable to arrest the sink rate before the airplane collided hard with the runway.
Aircraft Examination
Post-accident examination of the airplane revealed that both the left and right wing spars were bent downward. No other damage items were specified.
