Probable cause

The pilot-in-command's poor weather evaluation which resulted in a takeoff into adverse weather conditions and a loss of airplane control.

Analysis

The pilot had made several stop and go takeoff and landings at the private grass strip. During takeoff to the south, at an altitude of aprx 100 ft, the pilot stated that the airplane started an uncontrollable descent, striking the ground in a near vertical nose down attitude. He stated that the controls were not effective during the descent. The flight controls were examined, and continuity was confirmed. The pilot reported that a squall line was approaching from the west, and believed it was FAR enough away to not be a problem.
