The pilot reported that he was flying a private wildlife biologist over an area of a national park to observe and track wolves using radio telemetry. The pilot stated that during the initial 2 hours of the flight there was no significant turbulence, only what he characterized as light chop. The pilot indicated that just prior to the accident he flew over a ridge that rose to about 500 to 800 feet above the ground. When the pilot maneuvered the airplane to reverse direction toward the ridge, it encountered turbulence and downdrafts that increased the airplane’s bank angle and pushed it towards the ground, ultimately causing it to strike trees and the ground. A postaccident examination of the airplane revealed no mechanical malfunctions or failures that would have precluded normal operation. Additionally, a warning had been issued to airmen for the possibility of severe or greater turbulence, severe icing, low-level wind shear, and instrument flight conditions in the general area at the time of the accident.
Probable Cause: The pilot's decision to maneuver at a low altitude over rising terrain in conditions conducive to turbulence/downdrafts, resulting in a loss of control and impact with terrain.
