Confidence Rating: Accident investigation report completed and information captured
The Curtiss C-46 had been cleared for a straight-in instrument approach. The crew were told to maintain 3000 feet until leaving the Downey marker. The aircraft descended below this altitude and crashed into a hill at 980 feet altitude. At the time of this accident Robin Airlines, Inc., was doing business as North Continent Airlines, although no authorization to change its name had been obtained from the Civil Aeronautics Board.

PROBABLE CAUSE: "The action of the pilot in voluntarily descending below the minimum altitude for which he was cleared, and attempting an approach at an altitude too low to clear the terrain."
