Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot reported that the accident occurred during a mountain flying familiarization flight from an airport having a field elevation of 3,900 feet mean sea level. At the time of the pilot's takeoff from runway 32, which was 2,000-feet-long and 40-feet-wide, the wind was from 020 degrees at 10 to 15 knots. The pilot indicated that after liftoff, while the airplane was still in ground effect, he failed to maintain a flight track over the runway's centerline. The airplane drifted left, its left wing tip impacted bushes adjacent to the runway, and the airplane came to rest with a bent fuselage and ripped wing skins. The pilot indicated that the accident would have been prevented had he adequately compensated for the crosswind condition.
