Aircraft
[This was a] VFR flight after maintenance. [In the] post maintenance preflight; no water or contaminates were seen in fuel samples. The engine failed after 1.2 hours of operation. Engaged carb heat; engine returned to cruise RPM. Engine failed again; contacted Tower on (approximately 10 miles away) and requested priority handling. Engine failed again and returned to limited power 2 more times prior to touchdown. Prepared to make an off airport landing on a hay field but turned east and landed into the wind and uphill on a grass strip with farm buildings. Once stopped contact was made with another aircraft on the Tower frequency who relayed that there was no damage or injuries. Tied aircraft down. Aircraft grounded until released by maintenance. Atmospheric conditions were conducive for carb ice development however actual cause of failure has not yet been determined.
Bellanca pilot reported an engine failure during post maintenance flight. After troubleshooting the engine multiple times the engine failed completely. Requested ATC assistance and executed a safe off airport landing with no aircraft damage or injuries.
