The NTSB's narrative final · quoted from the NTSB record
The private certificated pilot was departing a remote ridge top at the end of a hunting trip. The wind was from the east about 5 knots. He loaded the airplane with moose and caribou meat, and departed the ridge top toward the east. During the takeoff roll, an approximate 20 knot gust of wind struck the airplane from the right. The airplane was pushed to the left, and the left wing struck some bushes. The airplane pivoted to the left and descended downhill. After the airplane came to rest, it caught fire, and was destroyed.
