THE PLT ATTEMPTED TO CONTROL THE RIGHT PROPELLER. FINALLY, THE RIGHT ENG WENT TO 2300 RPM & STABILIZED THERE. THE PLT INFORMED ATC & BEGAN AN IMMEDIATE DESCENT TO THE NEAREST ARPT. AT ABOUT 7000 FT, THE LEFT ENG BEGAN RUNNING ROUGH & PROGRESSIVELY BECAME WORSE. AS THE LEFT ENG RPM DECREASED TO ABOUT 1500, THE LEFT PROPELLER WAS FEATHERED.
