The pilot's inability to maintain adequate airspeed which resulted in an inadvertent stall/mush. Factors contributing to the accident were the unfavorable weather condition, mountain wave and the high density altitude.

Read the full NTSB narrative

As the pilot taxied out for takeoff, he noted that the windsock indicated a no wind weather situation (he had not received a forecasted winds aloft briefing). The pilot reported that he departed east towards the mountains and was climbing at 85 to 90 knots indicated airspeed (IAS). He turned the airplane southwest and climbed through 10,000 feet (approximately 11,000 feet density altitude) when his IAS dropped between 60 to 65 knots. He said the airplane began to descend at 800 to 1,200 feet per minute, and he could not get the airplane's nose down 'even with full forward yoke.' The pilot reported that he kept the wings level and 'pulled [the] yoke back full somewhere close to impacting the trees.'
