NTSB Factual Report

According to the pilot, during the final approach to a wet grass strip the airplane encountered a downdraft. Upon touchdown, the airplane began to drift to the left, and the pilot corrected with right rudder. The left main landing gear impacted two concrete driveway's off of the left side of the runway which protrude from the ground between four and six inches. After impacting the second driveway the left main landing gear separated and impacted the empennage. The left wing spar was bent. An examination of the airplane's systems, conducted by the FAA, revealed no anomalies. The pilot confirmed that there was nothing mechanically wrong with the airplane at the time of the accident.

NTSB Probable Cause

The pilot's failure to maintain directional control during the landing roll.
