NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.

The pilot had received four weather briefings prior to departing on the cross-country flight between Long Beach and Mammoth, California. The briefer informed the pilot that variable weather conditions existed, including mixed icing in clouds, mountain obscurement, and precipitation. No flight plan was filed for the dark nighttime flight over the high mountainous terrain. Witnesses heard the airplane, with its engine running, collide with trees and terrain near their mountain campground. The accident site was at an approximate elevation of 7,300 feet msl. The witnesses estimated that the ceiling was about 200 feet above ground level, and snowing. The pilot's medical certificate had expired. The FAA declined to issue the pilot another medical certificate because his diabetes was insufficiently controlled.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

the pilot's continued flight into instrument meteorological conditions during dark nighttime over mountainous terrain; and his failure to maintain an adequate altitude to ensure terrain clearance. Thw weather and terrain were factors.
