Analysis

After taking off from ft Smith, the plt leveled at 500 ft AGL & followed a river to look at some property aprx 5 mi away. While en route, the engine began to sputter & run irregularily. He performed a successful precautionary landing in a field where he made a thorough engine run-up & all systems checked normal. Thinking that the engine may have passed some water, he elected to takeoff & fly to hardin, MT. Aprx 2 min after takeoff, the engine began sputtering & running irregular again; however, the pilot could get no improvement when he attempted to restore the power. A forced landing was made in a field beyond some power lines. While applying heavy brakes to stop before reaching a ditch, the plane nosed over. An exam of the acft & engine was made, but no cause for the power loss was found.
