A pilot attempting to gain altitude over a 5,000-foot pass found the aircraft unable to climb sufficiently and initiated a turn to reverse direction, resulting in a collision with terrain at 3,000 feet.

What happened

The pilot reported that as she approached a mountain pass with an elevation of 5,000 feet, she initiated a climb in an effort to gain sufficient altitude for safe passage. However, the aircraft failed to climb at a rate fast enough to reach the necessary crossing altitude. Consequently, the pilot decided to execute a turn to reverse her direction of travel.

During this maneuver, the aircraft collided with the mountain terrain at an altitude of 3,000 feet. The pilot later stated that she had not previously attempted to fly through this specific pass prior to the incident.
