Probable cause

Analysis

After takeoff on an IFR cross country flight, the pilot commenced a 180 degree turn after entering the clouds at 300 feet AGL. The instruments indicated differently than his physiological senses and he was unable to maintain control of the aircraft which descended in a spiral and collided with the ground approximately two miles from the takeoff airport.
