Aircraft
In cruise flight 140 miles after departing; the #1 Propeller oil pressure began to decrease. We complied with the QRH (quick reference handbook) and monitored oil pressure until oil pressure declined requiring shutdown action. ZZZZ airport was closest to us with emergency services and I requested deviation there and airport emergency services were alerted. Descent; Approach and landing were normal and Emergency services meet the aircraft at the local FBO facility. Passengers were transferred to a commercial flight and enroute to destination within hours of landing. Company flew out needed parts and mechanic. Repairs were made that same day and aircraft was returned to service after repairs were accomplished.
I was serving as SIC on the flight and we experienced a loss of left prop. oil pressure. Also we were able to visually confirm that there is an oil leak coming from the left Eng. We ran the QRH and shutdown the left engine to prevent catastrophic damage due to lack of oil lubrication. After shutting down the Eng. we deviated to ZZZZ where we have safely landed.
SF340 flight crew experiences loss of oil pressure and the engine is shut down. The flight diverts to the nearest suitable airport.
