Flight Profile
The flight was conducted by a certificated commercial pilot. During the cruise phase, the aircraft was at 4,500 feet MSL. Due to high wind conditions, the pilot lowered the altitude to 3,000 feet MSL. As the terrain below began to rise, the pilot started a climb to keep the aircraft at an altitude of about 1,300 feet above the ground.
Turbulence and Control Attempt
While climbing, the airplane encountered severe turbulence and downdrafts. The pilot strove to maintain control and applied full engine power to establish a climb attitude. The indicated airspeed during this maneuver was approximately 80 MPH. Despite these actions, the aircraft was unable to gain altitude and continued to descend.
Terrain Impact
The descent carried the airplane into upsloping terrain that was covered with rock and snow. The aircraft struck the ground while still in a climb attitude. The impact inflicted damage to the wings, the fuselage, and the engine.
