NTSB narrative
The pilot received a preflight weather briefing and filed a VFR flight plan prior to departing Sacramento, California. During the briefing, the pilot was advised of forecast IFR conditions, with ceilings occasionally less than 1,000 feet and 3 miles visibility. Airmets advised mountain obscuration with scattered moderate to heavy rain. The FSS briefer concluded that after 1900-2000, the weather was going to reduce conditions to marginal VFR flight conditions. When the pilot opened his VFR flight plan by radio the briefer again asked him if he had the airmet for mountain obscuration, IFR conditions, and current information for the route. The pilot said yes he did and the briefer concluded by telling the pilot that VFR flight was not recommended. After the pilot arrived at Livermore airport he was asked by the local controller if he had a clearance on file or if he'd like to file one before he departed Livermore, and the pilot declined. The accident site was located between the elevation of 1,900 to 2,000 feet msl on a route consistent with a downwind departure from Livermore. A weather study by the Safety Board found that the airplane most likely experienced light to moderate rain after takeoff, with the airplane encountering heavy to very heavy rain near the accident site. Witnesses who were in the vicinity of the accident location confirmed that it was raining heavily near the accident timeframe.
Probable cause
The pilot's disregard for the preflight weather briefing, and his intentional continuation into adverse weather conditions.

- 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 1999-01-20.
