NTSB narrative
THE PILOT WAS ON AN IFR FLIGHT PLAN LEVEL AT 10,000 FEET MSL IN VFR CONDITIONS. THE ATP RATED PILOT WAS THE SOLE OCCUPANT, AND THERE WAS NO AUTOPILOT INSTALLED IN THE BEECH C-99 AIRLINER. ABOUT 10 MINUTES AFTER A HAND-OFF FROM LOS ANGELES CENTER TO OAKLAND CENTER WAS ACKNOWLEDGED, RADAR CONTACT WAS LOST AT 0239 HOURS. A REVIEW OF THE RADAR DATA REVEALED THAT OVER THE LAST 4 MINUTES THE AIRPLANE'S ALTITUDE INCREASED TO 10,500 FEET, THEN IT STARTED A LEFT DESCENDING TURN WITH A MAXIMUM DIAMETER OF ABOUT 2.1 NM. THE LAST RADAR RETURNS INDICATE THE AIRPLANE CONTINUING THE LEFT TURN AND DESCENDING THROUGH 5,600 FEET MSL, WITH A DESCENT RATE OF ABOUT 18,000 FEET PER MINUTE. THERE WAS NO EVIDENCE OF A MECHANICAL MALFUNCTION OF THE AIRCRAFT, ENGINES, OR PROPELLERS.
Probable cause

- 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: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
