BE-18 PLT RUNS OUT OF GAS.

Narrative

WHILE SBOUND APPROX 3 NM FROM MARSHALL AIRFIELD (5D8) FLYING AT 8000 FT MSL AND CLBING WITH 10 SKYDIVERS ON BOARD; MY L ENG BEGAN TO RUN ROUGH. AFTER EVALUATING THE PROB WE WERE OVER 5D8; JUST ABOUT 1 MI SE. I ORDERED THE JUMPERS OUT OF THE AIRPLANE AND PROCEEDED TO FEATHER THE L ENG. KALAMAZOO APCH WAS WELL INFORMED OF THE PROB AND ASSISTED ME. I INFORMED KALAMAZOO APCH THAT I NEEDED TO GO TO MARSHALL UNICOM TO CLR TFC. FROM THIS POINT EVERYTHING SEEMED OPERATIONAL AND A SAFE LNDG COULD BE MADE ON 1 ENG. DURING MY DSCNT TO LAND; MY R ENG ON THE BEECH-18 BEGAN TO RUN EXTREMELY ROUGH. THE INDICATIONS WERE IDENTICAL TO THE PROB I HAD WITH THE L ENG. THE SIT BECAME CRITICAL AND I FELT IT ABSOLUTELY ESSENTIAL TO FEATHER THE R ENG ASAP. I FEATHERED THE R ENG AT ABOUT 6700 FT MSL OVER THE ARPT HDG NBOUND SETTING UP FOR A R DOWNWIND TO RWY 28 AT 5D8. A R TFC PATTERN WAS CHOSEN DUE TO THE FACT THAT GLIDERS WERE OPERATING JUST S OF THE FIELD. THE PATTERN WAS WELL ANNOUNCED AND EVERYONE IN THE PATTERN WAS AWARE OF THE SIT. THE LNDG WAS ACCOMPLISHED WITHOUT INCIDENT.
