Narrative:
The pilot reported that shortly after takeoff, the airplane's engine 'stopped and then started up again.' Soon after, the engine started to lose power again. A forced landing was made. When the aircraft was inspected, it was found that one of the spark plugs in each of the number 1, 4, 5, and 6 cylinders were 'finger' tight, and the second spark plug in the number 6 cylinder had completely separated from the cylinder. These plugs were removed by a mechanic for the pre-buy inspection prior to the pilots purchase of the airplane.

Probable Cause: The separation of a spark plug and 4 other spark plugs being 'finger' tight as a result of undertorquing by maintenance personnel when they were reinstalled following inspection. A factor was a lack of suitable terrain for the forced landing.
