Narrative:

While sbound approximately 3 NM from marshall airfield (5d8) flying at 8000 ft MSL and climbing with 10 skydivers on board, my left engine began to run rough. After evaluating the problem we were over 5d8, just about 1 mi southeast. I ordered the jumpers out of the airplane and proceeded to feather the left engine. Kalamazoo approach was well informed of the problem and assisted me. I informed kalamazoo approach that I needed to go to marshall unicom to clear traffic. From this point everything seemed operational and a safe landing could be made on 1 engine. During my descent to land, my right engine on the beech-18 began to run extremely rough. The indications were identical to the problem I had with the left engine. The situation became critical and I felt it absolutely essential to feather the right engine as soon as possible. I feathered the right engine at about 6700 ft MSL over the airport heading northbound setting up for a right downwind to runway 28 at 5d8. A right traffic pattern was chosen due to the fact that gliders were operating just south of the field. The pattern was well announced and everyone in the pattern was aware of the situation. The landing was accomplished without incident.

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.
