Confidence Rating: Accident investigation report completed and information captured
The pilot stated that during the initial climb after takeoff from the 1,350 feet long grass airstrip, the airplane's left wing contacted brush, the airplane pivoted 180 degrees, and the right wing struck the ground. The pilot said he was departing uphill, and the winds were five to ten knots. The pilot also indicated that the headwind stopped during the takeoff. The Cessna 150 Takeoff Distance performance charts for 1,600 pounds takeoff weight, 20 degrees Celsius, and sea level pressure altitude, indicate the required ground roll is 765 feet, and the distance to clear a 50 feet high obstacle is 1,435 feet. The chart provides a 10% reduction in distance for each 9 knots headwind, and a 15% increase in distance for dry grass. No correction is provided to account for the uphill slope.

Probable Cause: The pilot's inadequate preflight planning. Factors associated with this accident were the pilot's failure to use the takeoff performance charts, the short runway and uphill takeoff, and a sudden windshift.
