The Wildlife Observation Services Inc. Cessna 337 was conducting an aerial fire patrol and wildlife survey with the pilot and a biologist on board. The aircraft was based out of Grande Prairie, Alberta. At 1437 mountain daylight time, the pilot lost control of the aircraft during a low-level turn approximately 15 nautical miles west of Beaverlodge, Alberta. The aircraft descended steeply through trees, skidded, and came to rest at the edge of a beaver pond. The aircraft was substantially damaged and the pilot was fatally injured. The biologist, who was seated in the front right seat, sustained serious injuries.
The emergency locator transmitter did not activate; however, locating the aircraft and survivor was facilitated by the global positioning system tracking equipment installed in the aircraft and the monitoring software used by Alberta Sustainable Resource Development flight following personnel.
Findings as to Causes and Contributing Factors
1. The pilot had not been provided with sufficient guidance and training pertaining to low-level aerial surveys; consequently, the pilot’s handling of the aircraft was not consistent with safe operations in the low-level environment.
2. The pilot flew the aircraft at low air speed, an angle of bank in excess of 50º, and a high-density altitude; this resulted in an aerodynamic stall.
3. The low altitude of the aircraft prevented recovery from the stall prior to striking the trees.
