Analysis

Shortly after departure at about 300 to 400 feet AGL, the airplane engine stopped running. The airplane crashed on the roof of a building and burned. An inspection of the engine revealed a sponge-like material lodged beneath and in the secondary venturi of the carburetor. The primary venturi of the carburetor was missing. The bracket air filter assembly was not found.
