PROBABLE CAUSE
Upon the basis of the foregoing findings and of the entire record available at this time, we find that the probable cause of the accident to aircraft NC 1946 on January 16, 1942, was the failure of the captain after departure from Las Vegas to follow the proper course by making use of the navigational facilities available to him.
