NTSB narrative
THE FLT HAD DEPARTED THE ALAMAGORDO WHITE SANDS REGIONAL ARPT AFTER A FUEL STOP. THE PILOT HAD EARLIER INDICATED TO ATC THAT HE WAS UNFAMILIAR WITH THE AREA. PRIOR TO DEPARTURE AT 2321 THE PILOT WAS INFORMED THAT DEPARTURE RADAR WAS OUT OF SERVICE. THE FLT DEPARTED WITH A VFR DEPARTURE. AT 2324 THE PILOT WAS ADVISED THAT RADAR WAS BACK IN SERVICE, AND CONFIRMED THAT THE AIRCRAFT WAS CLIMBING THRU 5,300 FT. DISCUSSION ENSUED BETWEEN THE PILOT AND CONTROLLER CONCERNING TERRAIN CLEARANCE. AT 2324 THE PILOT INDICATED HE WAS TURNING LEFT DUE TO NOT BEING SURE IF A HILL WAS IN HIS PATH. THE AIRPLANE IMPACTED A MOUNTAIN AT 6,100 FT MSL, 1,500 FT BELOW THE SUMMIT. THE MINIMUM VECTORING ALTITUDE IN THE AREA WAS 11,000 FT.
Probable cause
THE FAILURE OF THE PILOT TO EXERCISE ADEQUATE VFR DEPARTURE TERRAIN AVOIDANCE PROCEDURES, AND THE FAILURE OF THE CONTROLLER TO ISSUE A SAFETY ALERT TO THE PILOT. FACTORS WHICH CONTRIBUTED TO THE ACCIDENT WERE: THE PILOT'S LACK OF FAMILIARITY WITH THE GEOGRAPHIC AREA, THE DARK NIGHT, AND THE MOUNTAINOUS TERRAIN.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 1992-06-25.
