He stated that the three-point landing was “textbook” and on the runway centerline; however, during the rollout the airplane veered to the left. The pilot attempted to regain control of the airplane by applying rudder inputs but was not successful. The airplane exited the runway; the right main landing gear separated and the right wing then impacted the ground. The pilot reported that after the accident the passenger told him that he applied rudder during the landing to help the pilot. The pilot stated that in the future he would be more assertive whenever there was someone with access to controls as to who is the actual manipulator of the controls. ## Factual narrative The pilot reported that he was landing a tail wheel equipped airplane when he lost control and veered off the runway.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
