What was found
FLYING IFR, BUT SAW THE FIELD, GOT CLEARED FOR THE VISUAL APPROACH AT MIMLE. WHEN TURNING BASE TO FINAL AT AROUND 1100 FT FLYING AT 120 KNOTS, SUDDENLY THE NG STUCK. SAW THE POWER LEVER AT IDLE & NG WAS AT 88.2. COULDN’T SLOW DOWN. BUT CYCLED THE POWER LEVER, GETTING OFF COURSE ON FINAL. IMMEDIATELY BROUGHT FUEL CONDITION LEVER TO LOW IDLE WHICH SLOWED DOWN PLANE. COMMITTED TO LAND & AIMING TOWARDS THE RNWY. OVER THE NUMBERS STILL FELT FAST SO CUT THE FUEL CONDITION LEVER & SHUT DOWN ENGINE, FEATHERED PROP. SAFELY LANDED AND, WERE FASTER THAN NORMAL & COULDN’T USE BETA OR REVERSE, ASSISTED WITH THE BREAKS IN STOPPING JUST IN CASE. ABLE TO SLOW DOWN TO A SAFE SPEED A LITTLE BIT AFTER TAXIWAY C, ROLLED ALL THE WAY DOWN TO TAXIWAY A. BARELY MAKING IT OFF THE RUNWAY, WHERE WE CAME TO A FULL STOP. QUICKLY NOTIFIED TOWER ABOUT SITUATION & REQUESTED A TOW. RIGHT AFTER THAT, I BRIEFED THE PASSENGERS ON THE SITUATION. THANKFULLY EVERYONE WAS VERY UNDERSTANDING AND KIND ENOUGH TO THANK US FOR THE SAFE LANDING. TOWER ASKED US IF WE COULD START THE ENGINE AGAIN, ATTEMPTED BUT THE STARTER WAS NOT WORKING & PROPELLER DID NOT SPIN, IMMEDIATELY STOPPED AND TOLD TOWER AND CONTINUED TO REQUEST THE TOW. TOW TRUCK CAME & QUICKLY ASSISTED US.
