Investigator assessment
Analysis narrative
The pilot reported that, he was landing his tailwheel-equipped airplane on an asphalt surfaced runway in a slight right crosswind. After touchdown, the airplane veered to the right. Not knowing the reason for the veer, the pilot allowed the airplane to turn to the right and did not attempt to correct. The airplane ground looped to the right and the left wing impacted the ground sustaining substantial damage to the left wing and aileron. The pilot reported no preaccident mechanical failures or malfunctions that would have precluded normal operations. In the recommendation section of the NTSB Accident/Incident Reporting Form 6120.1, the pilot listed multiple ways the accident may have been prevented, including but not limited to, receiving additional training on landing technique in the airplane.
