A pilot attempted an emergency landing after realizing the aircraft could not climb over rising terrain following takeoff, resulting in a collision with trees.

What happened

Following takeoff, the pilot decided to turn into a valley to establish a more direct flight path toward the intended destination. Once committed to this route, it became apparent that the aircraft lacked the performance capability to climb above the rising terrain ahead. In an effort to avoid the obstacle, the pilot attempted to land the aircraft at the specific point where the aircraft's climb gradient intersected with the ground. During this emergency landing attempt, the aircraft struck trees.

Findings

Subsequent analysis of the flight conditions indicated that the density altitude was approximately 5,000 feet at the time of the incident. This high density altitude likely contributed to the reduced climb performance of the aircraft, preventing it from clearing the terrain despite the pilot's efforts to execute an emergency landing.

Probable cause

The pilot's failure to ensure adequate climb performance in high density altitude conditions while navigating rising terrain.
