Investigation Summary
The accident occurred as the Lockheed Constellation was attempting to land at Tahoe Valley Airport, which lacked an approved instrument approach procedure. Despite forecasts of heavy snow and icing, the airline's dispatcher and station manager provided misleadingly optimistic weather data to the crew. After encountering severe weather and icing at the destination, the crew abandoned the approach and attempted to navigate toward Reno via Daggett Pass. However, due to a combination of structural icing, a malfunctioning compass system (reported 11 times in the prior 8 months), and 'sticky' altimeters, the aircraft failed to maintain the necessary clearance. It struck trees on the west slope of Genoa Peak at 8,675 feet, just 300 feet below the ridge line. The subsequent CAB investigation found that the maintenance performed on the aircraft's critical instruments was conducted by unqualified personnel who did not consult technical manuals.
Final Conclusions
The Civil Aeronautics Board determined the probable cause was the pilot's deviation from prescribed VFR procedures by attempting a visual approach in adverse weather. This led to an abandoned approach and subsequent geographical disorientation while flying below the minimum safe altitude for mountainous terrain. Contributing factors included the falsification of weather reports by airline personnel and the operation of an aircraft with multiple known instrument deficiencies and no de-icing equipment.

Safety Actions & Advisories
Revocation of Operating Certificate
Following the discovery of multiple safety violations and the falsification of weather data, the FAA suspended and later permanently revoked Paradise Airlines' operating certificate.
