The commercial certificated pilot landed on a remote area of tundra to pick up a hunting partner. He said the wind conditions were gusty as he landed in a northwest direction. He shut off the engine and was preparing to exit the airplane. As he was sitting in the airplane, still strapped in the seat harness, a gust of wind blew the airplane over on its back. The airplane received damage to the overhead cabin structure, and the right wing lift strut was kinked. In the Pilot/Operator report (NTSB Form 6120.1/2) submitted by the pilot, the pilot indicated the wind velocity at the accident site was 40 knots, with gusts to 50 knots.
