Aircraft involved

Probable cause & findings

The pilot’s failure to maintain directional control during the takeoff roll.

Factual narrative

The pilot reported that during the takeoff roll, the airplane drifted to the left and he corrected with right brake input. The airplane began drifting left again, and the pilot was unable to correct with right rudder or brake. The airplane briefly became airborne and then landed in the grass to the left of the runway. The airplane sustained substantial damage to the engine mount. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
