Analysis

The pilot stated that he was flying low in a valley. He was unable to achieve sufficient altitude to clear trees at the top edge of the valley, which was about 150 feet of elevation change. He stated the air temperature and light breeze created a downdraft at the top of the valley which contributed to the airplane's insufficient climb and airspeed. The pilot also stated that he demonstrated poor judgment to be flying low in a valley.
