Overview
The accident occurred when the airplane collided with mountainous terrain in a box canyon during an attempted course reversal. The flight was being conducted with a Certified Flight Instructor (CFI) and a student pilot on board.
Sequence of Events
According to statements from both the CFI and the student pilot, the airplane approached a 3,400-foot mountain ridgeline while cruising at an altitude of 3,000 feet mean sea level. The crew elected to fly up the center of a box canyon that led toward the ridge, a decision made to keep the airplane as far from the ground as possible while maintaining altitude.
As they neared the ridge, the CFI initiated a climb to 3,500 feet. However, it became apparent that the airplane would not clear the ridge. In response, the CFI executed a left turn and intentionally stalled the aircraft. The purpose of this maneuver was to attempt a survivable landing on the mountain slope. The airplane subsequently struck the terrain.
Post-Accident Investigation
Examination of the airframe and engine found no evidence of any preimpact mechanical malfunctions or failures. The investigation relied on witness statements and physical evidence.
