Accident Number: WPR20CA271
Date & Time: August 16, 2020, 08:00 Local 
Registration: N62130
Aircraft: Ryan ST3KR 
Aircraft Damage: Substantial
Defining Event: Loss of control on ground
Injuries: 1 None
Flight Conducted Under: Part 91: General aviation - Personal


The pilot of the tailwheel equipped airplane reported that, while landing he elected to change from a three-point landing to a two-point landing. Upon touch down, the airplane veered left and departed the runway surface. The pilot elected to go around and "applied full right rudder and power." Concerned the airplane would not gain enough altitude to clear the obstacles, the pilot reduced engine power and landed off the runway surface. Subsequently, the airplane impacted vegetation and the left main landing gear collapsed. The airplane sustained substantial damage to the left wing.

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

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot's failure to maintain directional control during landing, which resulted in a runway excursion and impact with vegetation.
