Probable cause:
On the basis of the foregoing findings of fact and upon all of the evidence available at this time, investigators find that the probable cause of the accident was the malfunctioning of the Salt Lake radio range and that substantial contributing factors to the accident were:
the failure of the communications operators at Tintic, Plymouth, and Salt Lake City, Utah, whose duty it was to monitor the range, to detect its malfunctioning and immediately notify those concerned; and the failure of the pilot to follow to the fullest extent established radio range technique in accordance with the requirements of the procedure established by United and approved by the Civil Aeronautics Administration.
