NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

THE PILOTS WERE MAKING AN NDB APPROACH TO AN UNCONTROLLED AIRPORT THAT WAS 941 FEET MSL. THE NDB WAS 1.8 NM FROM THE AIRPORT, AND THE PILOTS WERE SUPPOSED TO MAINTAIN MINIMUM DESCENT ALTITUDE (MDA) OF 1,540 FEET UNTIL THE RUNWAY WAS IN SIGHT. PRIOR TO THE CRASH, ATC HAD TOLD THEM THAT THEY WERE 15 MILES FROM THE AIRPORT. APPROXIMATELY FOUR MILES FROM THE AIRPORT, THE AIRPLANE IMPACTED THE TOP OF A HILL, AT A POINT 990 FEET MSL. THE AIRPLANE WAS DEMOLISHED BY IMPACT AND POST-IMPACT FIRE. THE WEATHER WAS ESTIMATED TO BE 300 FEET OVERCAST AND ONE MILE VISIBILITY. NO MECHANICAL MALFUNCTIONS WERE REPORTED OR DISCOVERED. THE LACK OF A LOCAL ALTIMETER SETTING INCREASED THE MDA BY 240 FEET.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

IMPROPER IFR PROCEDURE BY THE PILOT BY NOT MAINTAINING THE MINIMUM DESCENT ALTITUDE (MDA) FOR THAT SEGMENT OF THE APPROACH. FACTORS RELATED TO THE ACCIDENT WERE: DARKNESS, LOW CEILING, FOG, AND RAIN.
