NTSB narrative

THE PILOT DEPARTED OAKLAND, CALIFORNIA, FOR A NIGHT VFR FLIGHT TO THE LOS ANGELES AREA. HE REQUESTED VFR FLIGHT FOLLOWING ALONG HIS ROUTE OF FLIGHT. SHORTLY AFTER BEING HANDED OFF TO LOS ANGELES ATC, HE WAS ASKED HIS NEXT POINT OF NAVIGATION. THE PILOT SAID HE WAS GOING DIRECT GORMAN, DIRECT BRACKETT FIELD. THE PILOT WAS INSTRUCTED TO CONTACT LA ATC, SECTOR 13. THE PILOT WAS UNABLE TO CONTACT THAT SECTOR, AND WAS TOLD BY THE PREVIOUS SECTOR TO REATTEMPT CONTACT IN 15 MILES. NO FURTHER RADIO COMMUNICATION WAS RECEIVED BY THE PILOT. THE ACCIDENT SITE WAS LOCATED APPROXIMATELY 16 MILES WEST OF THE GORMAN VOR; THE VOR TO WHICH THE PILOT INDICATED HE WAS GOING TO FLY 'DIRECT'. ACCORDING TO WEATHER INFORMATION AND SUN/MOON TABLES, IT WAS AN EXTREMELY DARK NIGHT WITH VERY LITTLE MOON ILLUMINATION. THE MAXIMUM ELEVATION FIGURE FOR THIS PARTICULAR QUADRANGLE ON THE VFR SECTIONAL IS 9,200 FEET MEAN SEA LEVEL. THE ELEVATION OF THE CRASH SITE WAS APPROXIMATELY 8,750 FEET MSL.

Probable cause

THE PILOT IN COMMAND DID NOT MAINTAIN ADEQUATE CLEARANCE WITH THE TERRAIN. FACTORS IN THIS ACCIDENT WERE: THE DARK NIGHT, AND THE POOR IN FLIGHT PLANNING AND DECISION MAKING BY THE PILOT.

  • 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 1993-09-20.
