Aircraft involved

Probable cause & findings

The pilot's loss of directional control during the touchdown and the subsequent attempted aborted landing which resulted in a runway excursion and impact with terrain.

Factual narrative

The pilot reported that he flew the airport traffic pattern to final approach. While on final approach, the pilot trimmed the airplane to a nose-high pitch attitude and his view of the runway was obscured. The pilot reported that he believed the airplane's airspeed dropped below the aerodynamic stall speed and the airplane yawed to the left. When the airplane touched down on the runway, the pilot reported that the airplane veered left, he applied full power in an attempt to abort the landing. The airplane continued to veer left, exited the left side of the runway and impacted terrain. The airplane sustained substantial damage to the wings, right horizontal stabilizer and right elevator. The pilot reported no preimpact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.
