Primary finding
Probable cause
The pilot’s improper flight control inputs which resulted in a loss of directional control and a nose-over.
Investigator assessment
Analysis narrative
The pilot of the tailwheel-equipped airplane reported that during takeoff he pushed forward aggressively on the control stick which resulted in a nose-down pitching moment exacerbated by fuel sloshing forward in the wing fuel tanks. In an effort to correct for the pitching moment, he pulled aft on the control stick which caused the tailwheel to impact the ground and the airplane veered to the left. Unable to correct for the veer, he applied the brakes too hard which resulted in a nose-over. The airplane sustained substantial damage to the right lift strut and vertical stabilizer. The pilot reported that there were no preaccident mechanical malfunctions or anomalies with the airplane that would have precluded normal operation, and that the accident may have been prevented if he had been less aggressive when applying flight control inputs.
