NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

The student pilot reported that while on his fourth landing in the tailwheel equipped airplane, after touchdown the airplane was "a little out of alignment" and he "started to lose control". The student pilot further reported that he advanced the throttle to attempt an aborted landing but was unable to regain control of the airplane, the airplane veered off the runway to the left, he then decreased the throttle and the airplane rolled back onto the runway. 

A post-accident examination of the airplane revealed that the right wing tip struck the ground, which caused substantial damage to the right wing rear spar. 

The pilot reported that there were no pre impact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.

The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
The pilot's failure to maintain directional control during landing, and subsequent wing tip strike, which resulted in substantial damage to the rear spar.
