Aircraft involved

Probable cause & findings

The student pilot's failure to establish a positive climb rate during an aborted landing, which resulted in abnormal runway contact, a subsequent loss of directional control, runway excursion, and the right main landing gear collapsing.

Factual narrative

The student pilot of the tailwheel-equipped airplane reported that, during landing on runway 12, the airplane bounced and entered a nose high attitude. The student pilot aborted the landing, applied full engine power and pushed the nose down while leveling the wings, before he applied left rudder to crab the airplane into the wind. The airplane touched down a second time with the longitudinal axis of the airplane not aligned with the runway. The airplane veered left and exited the left side of the runway. The right main landing gear collapsed, and the airplane came to rest upright in the soft dirt terrain.The airplane sustained substantial damage to the right wing and fuselage. The student pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The airport's automated weather observation station reported that, about the time of the accident, the wind was from 80° at 8 knots. The solo student pilot reported that, during landing, the airplane bounced and entered a nose-high attitude. The student aborted the landing, applied full engine power, pushed the nose down while leveling the wings, and then applied left rudder to crab the airplane into the wind. The airplane touched down again with its longitudinal axis not aligned with the runway. The airplane veered left and exited the runway. The right main landing gear collapsed, and the airplane came to rest upright in the soft, dirt terrain. The airplane sustained substantial damage to the right wing and fuselage. The student reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
