Abstract	The National Transportation Safety Board determines that the probable cause of the accident was a navigational error by the flightcrew resulting from their use of the incorrect navigational facility and their failure to adequately monitor the flight instruments. Factors which contributed to the flightcrew's errors were: the nonstandardized navigational radio systems installed in the airline's Beech 99 fleet; intra-cockpit communications difficulties associated with high ambient noise levels in the airplane; inadequate training of the pilots by the airline; the first officer's limited multiengine and instrument flying experience; and the pilots' limited experience in their positions in the Beech 99.
