Incident Overview
A commercial pilot and a passenger were conducting a sightseeing flight. According to the pilot, approximately 30 minutes into the flight, he turned away from low elevation terrain and began flying lengthwise over a picturesque canyon.
Sequence of Events
As the terrain elevation increased, the pilot applied full engine power and initiated maneuvering at the best angle of climb airspeed. Despite these actions, the pilot indicated that he was unable to climb over the rising terrain. The airplane subsequently crashed into a box canyon.
Post-Accident Information
The pilot reported that no mechanical problems were experienced during the flight. The aircraft was destroyed in the crash. The investigation did not identify any pre-impact anomalies with the airframe or engine.
