Analysis

The airplane was on a climbout at approximately 1000 to 1200 feet m.s.l. when the engine quit and the pilot encountered an engine fire. The pilot elected to go back to the airport. The airplane crashed on the taxiway, and the airplane was substantially damaged. The pilot was not injured. Examination of the aircraft engine revealed a hole in the side of the engine combustion chamber liner. The turbine chamber and turbine blade were completely destroyed by the inflight fire and uncontained case failure.
