NTSB narrative
The airplane impacted steep mountainous terrain while climbing after departure approximately 5 miles to the southwest of the departure airport. The airport was surrounded by 7,600-foot to 8,000-foot mountain ridges to the north, south, and east. To the west was a 6-mile-long lake ending in a dam and then a descending valley. Weather was clear skies with winds from the southwest at 6 knots. The pilot flew a southwestern departure route from the airport that crossed rugged mountainous terrain within 5 miles of the airport. This route was not the departure route recommended by the Big Bear City Airport; however, this pilot had recommended this route to at least one other pilot he had flown with in the past. The pilot misjudged the altitude required to cross these mountains and collided with terrain. No preaccident anomalies were noted with the airplane or engine. Toxicology lab results indicated that the pilot had been exposed to marijuana within the 10 hours prior to the flight. Medical analysis indicated that the pilot may have been somewhat impaired by the affects of marijuana, but it is unclear what role such impairment might have played in the decision making that set the stage for this accident.
Probable cause
the pilot's inadequate decision regarding a departure route and his failure to maintain clearance with rapidly rising mountainous terrain. A factor in the accident was the pilot's impairment by the effects of exposure to marijuana within the 10-hour period prior to the flight.

- 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, coordinates. 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.
