What happened
The incident occurred while the pilot was conducting low-level flight operations in mountainous terrain with the primary objective of spotting deer. During this phase of flight, the pilot attempted to fly over a ridgeline where the ground elevation rose at a gradient steeper than the aircraft's available climb performance.
Recognizing the insufficient altitude margin, the pilot initiated a turn at low airspeed and low altitude to reverse course toward lower terrain. Due to the combination of low speed and high angle of attack required for the maneuver in tight terrain, the aircraft entered a stall. The stalled aircraft subsequently struck trees before impacting steep, rocky ground.
The investigation
The physical evidence indicated that the aircraft was operating at low airspeed and altitude when the loss of control occurred. The impact path involved initial contact with vegetation followed by a final collision with rugged topography consistent with the terrain profile described in the narrative.
Findings
The primary factor contributing to this accident was the pilot's decision to attempt to clear a ridgeline where the terrain rise exceeded the aircraft's climb capability. This action, combined with initiating a reversal turn at low airspeed and altitude, resulted in an aerodynamic stall. The lack of sufficient energy margin prevented recovery before impact.
Safety message
Pilots operating in mountainous terrain must ensure that their flight path remains within the performance envelope of the aircraft. Attempting to clear obstacles or ridgelines where the ground profile rises faster than the aircraft can climb is extremely hazardous, particularly when maneuvering at low speeds and altitudes near the stall boundary.
