Analysis

During the landing roll, the left wing caught on high weeds. The pilot lost control of the airplane, veered off the landing strip, and collided with a ditch paralleling the runway. There were no reported mechanical failures or malfunctions with the airplane at the time of the accident. The pilot reported that due to the runway having numerous pot holes, landings were conducted on the eastern edge of the runway.
