Analysis
On departure the crew identified an in flight fire. An immediate shutdown of electrical, environmental and pressurization systems was initiated and a return was made to the airport with a successful landing. The fire was discovered to have occurred in the area of the pressurization supercharger and had substantially damaged the aircraft. The crew and two passengers evacuated successfully without injury. The supercharger hose collapsed from deterioration. Oil spillage during servicing contaminated the hose.
