Flight Crew Human Performance
Descending from 9500 ft into cxu for trip to lal, engine began running very rough and experienced partial power loss. Made precautionary landing in a field 3 mi north of cxu. 25 liters of fuel was in wing tanks, but fuel bowl only was 1/2 full. Traveling with a&P mechanic. Suspect vapor lock during descent in 85 degree WX. Restarted 1 hour later and engine ran fine. Did a full power ground run and checked ok. Received permission from farmer to take off out of field. Flew 3 mi south to cxu and left the aircraft there pending further evaluation. Should have stayed higher on descent to cxu. If, I had planned to arrive over airport at 2000 ft instead of tpa, I would have made the airport with the power loss. Will now arrive over intended landing airports in high key position and spiral down to pattern altitude.

Title: PLT OF Z526 EXPERIENCED PWR LOSS AND LANDED IN A FIELD. ON BOARD A&P DETERMINED CAUSE AS BEING TEMPORARY. FLEW ACFT ON MAINT FERRY TO ARPT FOR FURTHER EVALUATION.
Narrative: DSNDING FROM 9500 FT INTO CXU FOR TRIP TO LAL, ENG BEGAN RUNNING VERY ROUGH AND EXPERIENCED PARTIAL PWR LOSS. MADE PRECAUTIONARY LNDG IN A FIELD 3 MI N OF CXU. 25 LITERS OF FUEL WAS IN WING TANKS, BUT FUEL BOWL ONLY WAS 1/2 FULL. TRAVELING WITH A&P MECH. SUSPECT VAPOR LOCK DURING DSCNT IN 85 DEG WX. RESTARTED 1 HR LATER AND ENG RAN FINE. DID A FULL PWR GND RUN AND CHKED OK. RECEIVED PERMISSION FROM FARMER TO TAKE OFF OUT OF FIELD. FLEW 3 MI S TO CXU AND LEFT THE ACFT THERE PENDING FURTHER EVALUATION. SHOULD HAVE STAYED HIGHER ON DSCNT TO CXU. IF, I HAD PLANNED TO ARRIVE OVER ARPT AT 2000 FT INSTEAD OF TPA, I WOULD HAVE MADE THE ARPT WITH THE PWR LOSS. WILL NOW ARRIVE OVER INTENDED LNDG ARPTS IN HIGH KEY POS AND SPIRAL DOWN TO PATTERN ALT.
