Incident Overview
A pilot reported that during the takeoff roll of a tail wheel-equipped airplane, the aircraft began yawing to the left as the tail was raised and the airplane transitioned to its main landing gear. The pilot applied right rudder to correct, then left rudder, but the control inputs resulted in a yaw oscillation. The oscillation caused the airplane to depart the left edge of the runway.
Sequence of Events
After the airplane left the runway surface, the right main landing gear tire dug into the ground. This asymmetric resistance induced a ground loop to the right. The airplane continued turning until it came to a stop, resting on its right wing tip and nose. The pilot did not report any injuries or fire, and no other aircraft or personnel were involved.
Pilot Experience
The pilot reported having accumulated 19 hours of total flight time in the accident airplane. Additionally, he had about 255 hours in a tail wheel-equipped homebuilt airplane that was similar in design but with approximately half the engine horsepower. The pilot did not specify the make, model, or registration of the accident aircraft, nor the date or location of the occurrence.
Investigation Findings
No probable cause was determined by the investigating authority, as the incident was described solely based on the pilot's account. The report does not assign causal factors or contributing elements beyond the pilot's described actions.
