Analysis

The pilot said the wind was from 200 degrees at 10 KTS, as he began his takeoff on runway 13. When the aircraft reached 20-30 feet AGL it began to sink and collided with the ground. The pilot said he thought he encountered a wind shear or change of wind direction which resulted in the sink.
