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 reported that he was landing the tailwheel-equipped airplane when he lost control and veered off the runway. 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.
