Probable cause

The pilot's failure to maintain adequate clearance with tree(s) during the initial climb. Factors contributing to the accident were the high density altitude and downdraft conditions.

Analysis

The pilot executed a southerly departure as per the advice of local pilots familiar with the 5600 foot MSL airstrip. During the initial climb the pilot lost sight of the creek bed he was following and chose to execute a climbing left turn. During the turn the aircraft encountered a downdraft. The left wing struck a tree and the pilot lost control of the aircraft. The aircraft then collided with terrain. The pilot reported the temperature as 70 degrees fahrenheit. A density altitude of approximately 8000 feet existed at the time of the accident.
