The defining event best describes what happened. - [Landing-landing roll: Loss of control on ground](https://openairdocs.org/ntsb-events/230) (defining event); cases with it: [All aircraft, 4,585 cases](https://openairdocs.org/ntsb-events/230/sequence.md) - [Landing-landing roll: Landing gear collapse](https://openairdocs.org/ntsb-events/094); cases with it: [All aircraft, 1,787 cases](https://openairdocs.org/ntsb-events/094/sequence.md) ## Analysis The commercial pilot was practicing touch-and-go landings in the tail wheel equipped airplane. He reported that the wind direction changed to a quartering tailwind after the airplane touched down. The pilot stated that he then lost directional control of the airplane and did not believe he had sufficient engine power to recover. During the accident sequence the left main landing gear failed and the airplane ground looped, resulting in substantial damage to the left wing and horizontal stabilizer. The pilot stated that the airplane and engine had no mechanical failures or malfunctions prior to the accident. ## Factual narrative The commercial pilot was practicing touch-and-go landings in the tailwheel equipped airplane.
