EMER OFF ARPT LNDG.

Narrative

STARTED FLT WITH SVC: BET-NSM-POS-BET. THE ACFT WAS TOPPED OFF WITH FUEL. DEPARTED PQS; PLT STATION; WITH 5 PAX; 45 GALLONS FUEL; APPROX 3 HRS OF FUEL; GROSS TKOF WT = 3471.1 WITHIN LIMITS. ACFT AIRWORTHINESS APPEARED OK. FIRST INDICATION OF ENG PROBS; ENG ROUGHNESS; LOW FUEL FLOW. THIS OCCURRED APPROX 5.6 MI NW OF BET WHILE APCHING INBOUND FOR A L DOWNWIND RWY 36 AT 800 FT. I STARTED TROUBLE-SHOOTING THE ACFT BY CHKING CTLS POS AND ENG GAUGES. FUEL FLOW APPEARED TO BE THE PROB. I ATTEMPTED TO CORRECT BY SWITCHING FUEL TANKS AND ENGAGING THE LOW FUEL BOOST PUMP THEN THE HIGH BOOST PUMP. THERE WAS NO CHANGE IN THE ENG PERFORMANCE OR FUEL FLOW. THE ACFT WAS NOT PRODUCING THRUST. I MAY HAVE TEMPORARILY HAD SLIGHT PARTIAL PWR. I REQUESTED RWY 18 BECAUSE CLOSER AND ADVISED BET TWR OF ENG PROBS. BEING UNABLE TO MAINTAIN ALT; OR GLIDE TO RWY 18; WHILE PROP WINDMILLING; I ADVISED TWR UNABLE TO MAKE RWY; LNDG THE TUNDRA. THERE WAS A CLR OPENING TO MY L INTO THE WIND; SO I TURNED ADDED FULL FLAPS AND PROCEEDED TO LAND WITH FULL AFT BACK PRESSURE THROUGHOUT THE TOUCHDOWN AND ROLLOUT. THE ACFT SAFELY ROLLED TO A COMPLETE STOP WITHOUT INJURY TO PAX OR KNOWN DAMAGE TO THE ACFT. I CHKED THE CONDITION OF THE PAX WHICH WAS OK AND CALLED TWR TO ADVISE OF LOCATION AND PAX CONDITION OK. I ALSO ADVISED BETHEL BASE OF LOCATION AND INCIDENT. FINALLY; I SECURED ACFT; INSPECTED ACFT FOR SAFETY AND DAMAGE; AND CHKED FUEL WHICH WAS 35-40 GALLONS (APPROX 2- 2 1/2 HRS REMAINING). ARPT SECURITY PICKED UP PAX WITHIN 5-10 MINS AFTER LNDG.
