The pilot’s failure to maintain clearance from rising terrain while operating in a canyon, which resulted in an impact with terrain
Investigator assessment
Analysis narrative
The pilot reported that, he entered a valley and descended to an altitude of about 300 to 500 ft above the ground. As the pilot began a climb to clear an upcoming ridgeline, he realized that the airplane would not clear the terrain despite making S-turns and adjusting to best rate of climb airspeed. Subsequently, he initiated an emergency landing and the airplane impacted terrain in a level attitude, which substantially damaged the left wing and underside of the airplane. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
