Narrative
The pilot reported that shortly after takeoff, while the airplane was approximately 100 to 150 feet above the ground, the engine lost power but did not stop completely. The pilot leveled the airplane to assess the possibility of landing on the remaining runway. As the nose was lowered, the engine regained power. The pilot then initiated a left turn to enter the traffic pattern. However, during the turn onto the downwind leg, the engine lost power again. The pilot turned the airplane toward the runway and began a forced landing approach to an adjacent field.
While descending, the pilot observed rising terrain ahead. To avoid stalling, the pilot turned 45 degrees toward the runway to bypass the rising terrain. Subsequently, the pilot noticed a barbed-wire fence in the flight path. The terrain beneath the airplane was described as uneven and rough. The pilot reported that he managed to keep the airplane flying until it encountered the fence. Each wing struck a fence post, causing the airplane to pivot and come to a stop approximately 80 to 100 feet beyond the fence.
Examination Findings
An examination of the airplane conducted after the event revealed no mechanical anomalies. The specific cause of the intermittent power loss was not determined.
