Confidence Rating: Accident investigation report completed and information captured
Narrative:
During the takeoff roll with an air density altitude near 7,400 feet, the pilot reported that the takeoff roll "seemed normal with a bit longer requirement as expected for high temperatures conditions". The pilot reported that after takeoff the climb performance was "low".

He stated that the wind shifted direction during the initial climb; he maneuvered the airplane into the wind, and to avoid power transmission line wires and a highway by "gradual right turning". While maneuvering, the airplane settled into a "mushing descent" and impacted terrain.

The pilot reported there were no pre-impact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation. During the impact with terrain the airplane sustained substantial damage to the left wing and empennage.

Probable Cause: The pilot's failure to maintain adequate airspeed, which resulted in the airplane exceeding its critical angle of attack while maneuvering and a subsequent aerodynamic stall.
