What happened
The pilot initiated a night visual flight rules (VFR) cross-country departure from Fresno, California, at approximately 2209 Pacific Daylight Time. He later cancelled his flight plan and landed at Ramona Municipal Airport at 0012 PDT. Following the landing, he contacted his wife to ask about weather conditions at Palomar Airport. She observed clear skies with visible stars and reported this to him. Relying on this information, the pilot departed Ramona at approximately 0017 for a short 23-mile flight.
Approximately 15 miles west of Ramona, the aircraft impacted a hillside within an avocado grove at an elevation of roughly 1000 feet above mean sea level. Local residents reported that the area was obscured by fog with visibility near one-half mile and a ceiling around 300 feet. The wind was calm, and the temperature was 56 degrees Fahrenheit. Reports indicated that the fog had persisted in the valley for two to three hours prior to the accident.
The investigation
Examination of the wreckage site and the aircraft components revealed no evidence suggesting an in-flight structural failure or loss of engine power. The physical evidence pointed to a controlled flight into terrain rather than a mechanical malfunction.
