NTSB narrative
THE PILOT TOOK THE AIRPLANE WITHOUT PERMISSION OF THE OWNER AND FLEW IT FROM AN AIRPORT NEAR HIS RESIDENCE. AFTER ABOUT 25 MINUTES, THE AIRPLANE COLLIDED WITH THE WEST SIDE OF MT RUBIDOUX, WHICH WAS ABOUT ONE MILE EAST-SOUTHEAST OF THE AIRPORT. AN EXAM OF THE CRASH SITE REVEALED EVIDENCE THAT THE AIRPLANE IMPACTED THE RISING TERRAIN WHILE IN A NEAR LEVEL FLIGHT ATTITUDE. ACQUAINTANCES REPORTED THE PILOT WAS FAMILIAR WITH THE AREA, HAVING FLOWN FROM THE AIRPORT FOR OVER 10 YEARS. REPORTEDLY, HE HAD RECENTLY BECOME UNEMPLOYED AND WAS DEPRESSED. TOXOCOLOGY RESULTS INDICATED THE PRESENCE OF COCAINE AND BENZOYLECGONINE IN THE PILOT'S BLOOD AT LEVELS OF 340 AND 1330 NG/ML, RESPECTIVELY.
Probable cause
IMPAIRMENT OF THE PILOT FROM USE OF DRUGS (COCAINE), AND HIS FAILURE TO MAINTAIN CLEARANCE (OR ALTITUDE) FROM THE MOUNTAIN. FACTORS RELATED TO THE ACCIDENT WERE: DARKNESS AND THE PILOT'S PSYCHOLOGICAL CONDTION (DEPRESSION).

- 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.
