Incident Overview
During a missed approach in night instrument meteorological conditions (IMC), the pilots reported an engine fire. They feathered the propeller and shut down the affected engine. Subsequently, while on approach to another airport, the airplane touched down short of the runway, traveled onto the runway, and then departed the left side of the runway.
The pilot reported that he could not maintain altitude due to ice accumulations and the lack of power with one engine shut down. He had been briefed about known moderate icing conditions and isolated severe icing. The Airplane Flight Manual (AFM) recommended a minimum speed of 140 knots in icing conditions; at speeds below 140 knots, ice could accumulate on the wings in unprotected areas. The pilot stated that he flew the approach at 114 knots.
Examination Findings
Post-accident examination of the wreckage revealed rotational damage to both engines and propellers, consistent with operating engines. Neither propeller was found in the feathered position.
