A pilot conducting a solo instructional flight encountered turbulence and cloud buildup while attempting to fly over a mountain, leading to a decision to divert that resulted in a collision with trees.

What happened

The incident occurred during a solo instructional flight where the pilot was tasked with navigating a course directly over a significant topographical feature. Specifically, the objective involved flying over a mountain with an elevation of 10,400 feet. As the aircraft climbed to the 5,200-foot level, the pilot encountered turbulent air conditions. During this phase of flight, the pilot observed a buildup of clouds forming over the mountain peak.

In response to these deteriorating visual and atmospheric conditions, the pilot made the decision to alter the planned route and divert to the north. However, before the diversion could be completed safely, the aircraft impacted trees in the area. The collision with the terrain resulted in the termination of the flight.

Probable cause

The pilot's failure to maintain visual reference during a mountain flight in deteriorating weather conditions, which led to controlled flight into terrain.
