Narrative:

Left carthage, il, about XXXX. WX cold, visibility 2500-3000' AGL and 1.5 mi. Heading 045 degrees to galesburg. Reached roseville 30 NM. Flew into snow, visibility poor, turned south for 25 NM. WX cleared--no snow. Turned east and ran into snow, visibility closing in. Started to look for an opening in the clouds to set down. Found an opening in the clouds at route 136 and 41. Made 5 passes on a field and then set the plane down with no problems. Landing relatively smooth--no damage to aircraft or myself. Used slow flight due to turbulence. Had maps with information, but with turbulence rather hard to use. Even though the WX had deteriorated, I remained rather cool and tried to use good judgement. The next morning, I towed the plane to a bean field and took off. I was very fortunate that everything came out ok. To prevent this type of flight from ever happening again, I won't underestimate the WX conditions, even if the flight time is 1/2 hour. When I took off, ceiling unlimited, visibility 10 NM. File a complete flight plan regardless of distance and complete WX report every time you fly. In doing this, there would be no problem or reason to set down due to bad WX closing in rather fast. There would also be a record with FSS or FAA on WX briefings. According to FAA in springfield, il, there were several aircraft that had problems that evening. Mechanical problems are another issue.

Narrative: LEFT CARTHAGE, IL, ABOUT XXXX. WX COLD, VISIBILITY 2500-3000' AGL AND 1.5 MI. HDG 045 DEGS TO GALESBURG. REACHED ROSEVILLE 30 NM. FLEW INTO SNOW, VISIBILITY POOR, TURNED S FOR 25 NM. WX CLRED--NO SNOW. TURNED E AND RAN INTO SNOW, VISIBILITY CLOSING IN. STARTED TO LOOK FOR AN OPENING IN THE CLOUDS TO SET DOWN. FOUND AN OPENING IN THE CLOUDS AT ROUTE 136 AND 41. MADE 5 PASSES ON A FIELD AND THEN SET THE PLANE DOWN WITH NO PROBS. LNDG RELATIVELY SMOOTH--NO DAMAGE TO ACFT OR MYSELF. USED SLOW FLT DUE TO TURB. HAD MAPS WITH INFO, BUT WITH TURB RATHER HARD TO USE. EVEN THOUGH THE WX HAD DETERIORATED, I REMAINED RATHER COOL AND TRIED TO USE GOOD JUDGEMENT. THE NEXT MORNING, I TOWED THE PLANE TO A BEAN FIELD AND TOOK OFF. I WAS VERY FORTUNATE THAT EVERYTHING CAME OUT OK. TO PREVENT THIS TYPE OF FLT FROM EVER HAPPENING AGAIN, I WON'T UNDERESTIMATE THE WX CONDITIONS, EVEN IF THE FLT TIME IS 1/2 HR. WHEN I TOOK OFF, CEILING UNLIMITED, VISIBILITY 10 NM. FILE A COMPLETE FLT PLAN REGARDLESS OF DISTANCE AND COMPLETE WX RPT EVERY TIME YOU FLY. IN DOING THIS, THERE WOULD BE NO PROB OR REASON TO SET DOWN DUE TO BAD WX CLOSING IN RATHER FAST. THERE WOULD ALSO BE A RECORD WITH FSS OR FAA ON WX BRIEFINGS. ACCORDING TO FAA IN SPRINGFIELD, IL, THERE WERE SEVERAL ACFT THAT HAD PROBS THAT EVENING. MECHANICAL PROBS ARE ANOTHER ISSUE.
