Probable cause

The pilot’s failure to maintain airspeed during the initial climb after takeoff, which resulted in an aerodynamic stall. Contributing to the accident was the pilot’s lack of total flight experience in the accident airplane make and model.

Analysis

The pilot was departing for his first flight in the airplane. According to a statement provided by the pilot to the airport manager, the airplane was about 50 feet above ground level when the left wing dropped. The pilot reported that he attempted to correct the wing drop by manipulating the ailerons only; however, he was unsuccessful in leveling the airplane. He then applied left rudder while applying right aileron and the airplane began to spin to the left. The airplane impacted the ground in an approximate 10-degree nose down, left bank attitude, which resulted in substantial damage to the wings and fuselage. According to Federal Aviation Administration records and photographs of the Hobbs meter, the airplane had accumulated 8.9 hours in the 2 years since the pilot had purchased it. The pilot stated that these hours had been accumulated during taxi tests, and that the accident flight was his first attempt to fly the airplane. According to the pilot, there were no mechanical malfunctions or abnormalities that would have precluded normal operation.
