Narrative:
The pilot was practicing off runway landings in the tundra at approximately 11,000 feet. He selected a landing area, made a few passes to inspect the site, and decided to land uphill. On short final, he "realized that my sink rate was higher than I was comfortable with, and my groundspeed was too high." He applied full power, but contacted the ground while the airplane was in a crab. Both main landing gear were broken off, and the wings were bent. The pilot said that after he exited the airplane, he noted that he had landed with a 20 knot quartering tailwind. He also stated that the ambient air temperature at the crash site was 60 degrees Fahrenheit. The calculated density altitude was 13,418 feet.



Probable Cause: the pilot's inadequate wind evaluation, and his inadequate planning/decision to land with a tailwind, at a density altitude of 13,418 feet. Contributing factors were the tailwind and the high density altitude weather condition.
