Flight and Weather Conditions
The pilot was conducting a visual cruise flight over mountainous terrain at an altitude of 6,500 feet. During the flight, the pilot observed clouds building at 5,000 feet and decided to return to the departure airport. To do so, the pilot descended through a gap in the clouds that was estimated to be between half a mile and one mile wide.
Encounter with Ice
At 4,500 feet, clear ice began to form rapidly on the airplane. The pilot then descended further to 2,500 feet in a mountain valley, where the airframe ice began to melt. Subsequently, the pilot initiated a climb to clear a ridgeline.
Collision and Post-Impact
While climbing, the airplane collided with trees and caught fire. The pilot reported no mechanical malfunctions with the airplane. Recorded weather data indicated low ceilings in the vicinity throughout the morning. The pilot stated that he did not obtain a weather briefing prior to the flight.
