Investigators recorded the probable cause as: THE FAILURE OF THE PILOT TO COMPLY PROMPTLY WITH ATC INSTRUCTIONS AND HIS LOSS OF CONTROL DUE TO SPATIAL DISORIENTATION. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

Accident Description
The pilot initiated a crosscountry flight and encountered instrument meteorological conditions (IMC) near his destination. He requested and received an IFR clearance. Subsequently, the pilot consistently did not respond to air traffic control (ATC) instructions. The final ATC vector to intercept the localizer course required a 220-degree right turn which would have resulted in a 30-degree angle of intercept. During the turn, aircraft control was lost and the aircraft crashed in a farm yard.
Wreckage and Systems Examination
Examination of the aircraft did not disclose evidence of mechanical failure or system malfunction. Inspection of the propellers showed impact damage consistent with cruise power. The wreckage examination indicated that the landing gear and flaps were in the up and retracted position.
Witness Reports
Witnesses reported hearing strong engine sounds prior to impact. No further details were available from witness accounts.
Pilot Information
The investigation could not determine the pilot's recency of instrument experience or instrument competency. No other pilot-related findings were reported.
