What happened
A commercial certificated pilot was attempting to depart from a small, east/west oriented airstrip located at a mining claim. The airstrip measured approximately 600 feet in length and 20 feet in width, featuring a slope ranging from 6 to 10 degrees.
To account for wind blowing downhill, the pilot elected to take off toward the west, which resulted in an uphill takeoff roll. At the time of the departure, winds were reported from the west at speeds between 10 and 15 knots. While the aircraft successfully lifted off, the tires remained only about 2 to 3 feet above the ground as the plane reached the end of the airstrip. During this phase, the tires began skimming the tops of low bushes surrounding the runway.
The pilot reported that the wind speed decreased during the maneuver, causing the airplane to contact the ground and nose over. The accident resulted in damage to the engine propeller, wings, and empennage. There were no injuries reported.
