Analysis

The acft was used for public rides at an amusement park. During the takeoff to ferry the acft back to an overnight parking space the engine quit at 100 ft AGL. The plt said he started the acft and hovered using fuel from the aft fuel tank. When the engine coughed he landed, switched tanks and took off. After takeoff the engine quit. Investigation showed the aft fuel tank was empty while the forward tank had ruptured. Some fuel lines had been cut for wreckage removal but there was fuel in the line between the carburetor and the fuel pump.
