Read the full NTSB narrative

The pilot reported that while flying along the west side of Monroe Mountain about 1,000 ft above ground level, the airplane encountered a downdraft near a river drainage at the southern end of the valley. The pilot applied full engine power, maneuvered to avoid a tree near the right wingtip, and attempted to maintain airspeed. During the maneuver, the airplane collided with another tree that the pilot had not seen. The airplane subsequently impacted terrain and was consumed by a postimpact fire. The pilot reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation.
