Aircraft involved
Probable cause & findings
The pilot's improper landing flare, which resulted in a bounced landing, and his subsequent exceedance of the airplane's critical angle of attack, which resulted in an aerodynamic stall.
Factual narrative
The pilot reported that, during his ninth touch and go, shortly after touchdown, the airplane bounced. He wanted to apply partial power and continue to land but he heard the safety pilot declare, "I have," the pilot response, "you have", and gave up controls to the safety pilot. Shortly after, the airplane rolled to the right, the right wing struck the ground, the airplane exited the runway and impacted terrain. The safety pilot reported that during landing, the left main landing gear touched down on the runway first, followed by the right main landing gear, and the airplane "popped up" with a nose high attitude. The airplane started to climb, continued to pitch higher and rolled to the right, so he "took" controls, applied power, and lowered the nose, but the right-wing tip struck the ground and the airplane impacted terrain. The airplane sustained substantial damage to the engine mount and truss. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
