Analysis

The pilot-in-command was on a personal flight with the purpose of observing a hunting camp from the air. While maneuvering in the canyon, the pilot stated he encountered a downdraft. He applied full power and lowered the flaps 20 degrees. The airplane continued to descend and the pilot elected to land on the canyon floor in the brush. The airplane rolled approximately 150 foot on its landing gear before nosing over.
