The pilot reported that, during the landing roll on asphalt, the tundra tire-equipped airplane yawed to the left, and he corrected with "significant" right rudder. He reported that he inadvertently engaged the right toe brake when he applied right rudder, "which led to a very rapid and unsustainable correction." The airplane ground looped to the right, and the left wing struck the ground. The airplane sustained substantial damage to the left wing and aileron. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Factual narrative According to the pilot in the tailwheel-equipped airplane, he was inexperienced flying this make and model.
