Aircraft involved
Probable cause & findings
The pilot's failure to maintain aircraft control during takeoff on an uneven runway surface, which resulted in it becoming airborne prematurely, an aerodynamic stall, and impact with terrain.
Factual narrative
The pilot reported that during the takeoff roll from a private, dirt airstrip the airplane encountered a bump and became airborne prematurely. The pilot further reported that he attempted to reduce the angle of attack, but the left wing aerodynamically stalled and the airplane impacted terrain. The airplane sustained substantial damage to the fuselage, left wing, right wing and aileron, and right vertical stabilizer. The pilot reported that there were no preimpact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.
