Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot was practicing a three point landing in the tailwheel-equipped airplane when the airplane veered to the left after touchdown. The pilot stated that when he tried to correct to the right, he heard an abnormal noise from the tailwheel, and the tailwheel locked. Examination of the accident site revealed that the airplane had exited the right side of the runway, hit a taxiway sign, traveled 50 more yards, and nosed over. Examination of the airplane revealed that the fabric was torn in numerous places, the propeller was broken, the forward left wing strut was bent, the right landing gear was broken and bent up under the fuselage, and the fuselage was twisted. The examination revealed no evidence of any preimpact failure or malfunction of the flight controls; the tailwheel moved freely to the left and right with rudder pedal application, and no binding was noted.

Factual narrative

While practicing three point takeoffs and landings in the tail wheel equipped airplane for a Federal Aviation Administration (FAA) required examination, the pilot experienced a loss of control when the airplane veered to the left after touchdown. The pilot stated that he tried to correct to the right but that he heard an abnormal noise from the tailwheel and then it locked. Examination of the accident site by an FAA inspector revealed that the airplane had run off the right side of the runway, hit a taxiway sign, traveled 50 more yards, and nosed over. Examination of the airplane revealed that its airframe was substantially damaged. The fabric was torn in numerous places, the propeller was broken, the forward left wing strut was bent, the right landing gear was broken and bent up under the fuselage, and the airframe exhibited evidence of torsional deformation. Further examination revealed no evidence of any preimpact failure or malfunction of the flight controls. No binding was discovered and the tailwheel would move freely to the left and right with rudder pedal application.
