Probable cause
The NTSB’s determination of the probable cause, and any contributing factors.
The pilot's poor inflight decision. Factors include mountainous/hilly terrain, trees, high density altitude, and downdrafts.
Analysis
The pilot of the rented Cessna 150 made a number of passes over the elk hunting camp in an area were the density altitude was over 7000 feet. He reported that, although there was very little turbulence in the area, the winds must have been fairly strong because the groundspeed of the aircraft was significantly different on each pass, depending on the direction the aircraft was heading. On the last pass, the pilot added power but was unable to outclimb the rising terrain. He reported that the engine seemed to be running fine, but the aircraft was descending at 800 feet per minute while at full power.
