Probable cause

An inadequate compensation for wind, and proper climb rate not being maintained. Factors include inadequate preflight planning, the pilot's over-confidence in his own ability and the ability of the aircraft, lack of experience in this type of operation, and a tailwind.

Analysis

The student pilot of the Cessna 177A attempted a downwind takeoff at the 1750 foot grass strip. Just after takeoff he realized that he was near a stall, and lowered the nose to pick up airspeed. When the nose was lowered, the aircraft began to sink, and ultimately impacted the terrain.
