Factual narrative
The pilot reported that as the tail wheel-equipped airplane touched down it began to veer to the left.

The pilot reported no mechanical failures or malfunctions with the airframe or engine prior to the accident. In a written statement, the pilot reported that the accident could have been prevented by receiving additional instruction with a certificated flight instructor in the airplane make and model.
