San Antonio - Eagle Pass

Shortly after takeoff, the pilot reported he had 'a problem' and needed to return immediately. Witnesses observed dark black smoke coming from both engines. The airplane collided with a tree 1/2-mile northeast of the runway threshold. Analysis of fuel samples revealed the presence of approximately 50% jet fuel. The right propeller was found feathered and engine disassembly revealed a hole burned in the right engine number 5 piston. Left engine disassembly revealed piston edges eroded down to the first compression ring. Fuel filler restrictors had been installed in the airplane's fuel tanks, but the fuel truck did not have the restrictive mating nozzle. The fuel truck was owned by the fuel vender and leased to the FBO.
