THE AIRLINE TRANSPORT-RATED PILOTS DEPARTED GRAND JUNCTION, CO, AT APPROXIMATELY 0345 MDT EN ROUTE TO FARMINGTON, NM, THEIR HOME BASE. AT 0351, THE FLIGHT LEVELED OFF AT 11,600 FEET ON A GROUND TRACK OF 135 DEGREES, AND MAINTAINED THAT HEADING AND ALTITUDE UNTIL RECORDED RADAR DATA ENDED AT 0407. ABOUT 0415, THE AIRPLANE IMPACTED A 14,246 FOOT MOUNTAIN AT THE 11,600 FOOT LEVEL. NO EVIDENCE OF PREIMPACT AIRFRAME, ENGINE, PROPELLER, OR FLIGHT CONTROL FAILURE OR MALFUNCTION WAS FOUND. AUTOPSY AND TOXICOLOGY PROTOCOLS CONDUCTED ON BOTH PILOTS FAILED TO DISCLOSE ANY PHYSICAL IMPAIRMENT. RECORDS SHOWED THAT BOTH PILOTS HAD BEEN ACTIVE SINCE 0800 THE PREVIOUS MORNING.
Probable Cause: FAILURE OF THE PILOT-IN-COMMAND TO PLAN AND/OR ASSURE SELECTION OF AN ALTITUDE/COURSE COMBINATION THAT WOULD PROVIDE TERRAIN CLEARANCE, AND FAILURE OF THE OTHER (SECOND) PILOT TO ADEQUATELY MONITOR THE SITUATION. DARKNESS, HIGH (MOUNTAINOUS) TERRAIN, AND PILOT/CREW FATIGUE WERE RELATED FACTORS.
