Incident Details
During a low-altitude reconnaissance mission for the Civil Air Patrol, the pilot inadvertently flew into a box canyon or area of rising terrain. Recognizing that he could not outclimb the terrain and was unable to turn to the right, the pilot executed a left turn. The airplane subsequently collided with terrain across a slope of approximately 15 degrees and nosed over after the initial impact.
Occupants and Injuries
The pilot and two observers sustained minor injuries in the accident. The pilot used a hand-held radio to communicate with air carrier aircraft to facilitate rescue.
Aircraft and Equipment
The airplane was equipped with a cargo net, but the net was not used to secure cargo. The cargo included a heavy steel instrument panel security lock device.
Investigation
The investigation documented the sequence of events leading to the collision, including the pilot's decision to turn left after being unable to outclimb or turn right. No further analysis or conclusions were provided in the source material.
