Probable cause
A partial loss of engine power due to a loose rocker arm adjustment nut on the number 6 cylinder. The loose adjustment nut was due to inadequate maintenance adjustment performed by the engine manufacturer.

Read the full NTSB narrative
During a local sightseeing flight, the engine started running rough. The pilot began a turn back toward the airport and noticed a decrease in power, which continued to escalate. He was unable to maintain altitude and selected a road to attempt a forced landing. During the landing, the airplane's right wing struck a telephone junction box. An exam revealed that the number 6 cylinder exhaust valve rocker arm adjustment nut was loose and the exhaust valve was not functioning. Review of the maintenance records disclosed that the valves were adjusted at the factory about 5 months and 200 hours prior to the accident.
