The pilot reported that he completed a full preflight inspection of the airplane with no issues noted, including inspecting all the flight control surfaces. During the run-up, the pilot checked all the flight controls and he noted they “all checked perfect.” The pilot was operating at a remote airport that was surrounded by pine trees, about 90 ft tall, on all sides. The takeoff roll from the snow-covered runway was “normal” and about 150 ft agl, the airplane “started turning/pulling left” in a descending turn. The pilot attempted to correct the turn and descent to no avail. The pilot decided to continue to use engine power until the airplane impacted trees. The airplane impacted several trees and came to rest nose down. The pilot was able to egress from the airplane without further incident. The airplane sustained substantial damage to the fuselage, both wings, and the engine mount. The pilot reported there were no preimpact mechanical malfunctions or failures with the airframe or the engine that would have precluded normal operation. A postaccident examination of the airframe established flight control continuity.
