Accident Details
The pilot, who was not instrument rated, obtained two weather briefings before the flight. During both briefings, the pilot was informed that visual flight rules (VFR) flight was not recommended. Despite this advisory, the flight departed at 1308 Pacific Standard Time. The aircraft failed to arrive at its destination, prompting a search.
An NTAP printout indicated several altitude changes during the flight.
Wreckage Location
The wreckage was located on the west face of a mountain ridge at an elevation of 11,800 feet above mean sea level. Due to the elevation, rugged terrain, and snow cover, the accident site was inaccessible for investigation.

The 1450 PST weather observation at Bishop, California, located 32 miles north of the site, reported 500 feet scattered clouds, an 800-foot overcast ceiling, and 3 miles visibility in light rain showers.
