"N2336X WAS ON A BUSINESS FLIGHT TO CODY, WYOMING. THE PILOT EXECUTED A MISSED APPROACH ON THE FIRST ATTEMPT OF THE VOR-A APPROACH. A PILOT WHO LANDED AT CODY MINUTES BEFORE THE ACCIDENT SAID THE VISIBILITY HAD DECREASED TO 3/4 OF A MILE WHEN N2336X MADE THE FIRST APPROACH AND APPROX 1/2 MILE WHEN N2336X CRASHED.

EXAMINATION OF THE WRECKAGE REVEALED NO EVIDENCE OF A MECHANICAL MALFUNCTION OR FAILURE OF THE AIRCRAFT PRIOR TO ACCIDENT. THE SAS SERVO ARM WAS FOUND IN THE FULL UP POSITION. THE AIRCRAFT STRUCK THE TERRAIN IN A STEEP NOSE LOW ATTITUDE ON A HEADING THAT WAS OPPOSITE TO THE DIRECTION OF FLIGHT. APPLICABLE MINIMUMS AT CODY ARE 5800 FEET & 1 MILE VISIBILITY.
