Narrative:

WX at takeoff was 800 ft scattered; 1900 ft broken 3 mi visibility. Radar showed light precipitation. About 200 ft in the air after takeoff; heavy rain started. Immediate decision was made to stay in traffic pattern and land. On downwind; visibility dropped to 1/4 mi and ceiling dropped to 500 ft AGL. Airport and ground visual were lost. Could not land in current conditions and now in solid IMC with 0 visibility. Decision was made to climb to try and regain visibility. Stopped at 6500 ft due to moderate turbulence which was increasing. Called 121.5 and gave mayday stating VFR pilot in IMC conditions need vectors to nearest airport. No reply to mayday. Switched to 122.0 and repeated mayday. No reply. Tried navigating to home airport but couldn't hold a heading and keep the wings level. Next decision was to descend. Set up for GPS approach and contacted CTAF. Unicom came on and advised visibility was improving on ground. Followed GPS approach and broke clear of clouds with visual of runway. Landed plane without incident.

Title: PA32 PILOT ENCOUNTERS HEAVY RAIN SHORTLY AFTER TKOF AND IS UNABLE TO MAINTAIN VFR CONDITIONS. AFTER ATTEMPTING TO GET ON TOP IN VAIN; PILOT IS ABLE TO FLY GPS APPROACH TO VFR CONDITIONS AND LAND.

Narrative: WX AT TKOF WAS 800 FT SCATTERED; 1900 FT BROKEN 3 MI VISIBILITY. RADAR SHOWED LIGHT PRECIPITATION. ABOUT 200 FT IN THE AIR AFTER TKOF; HVY RAIN STARTED. IMMEDIATE DECISION WAS MADE TO STAY IN TFC PATTERN AND LAND. ON DOWNWIND; VISIBILITY DROPPED TO 1/4 MI AND CEILING DROPPED TO 500 FT AGL. ARPT AND GND VISUAL WERE LOST. COULD NOT LAND IN CURRENT CONDITIONS AND NOW IN SOLID IMC WITH 0 VISIBILITY. DECISION WAS MADE TO CLB TO TRY AND REGAIN VISIBILITY. STOPPED AT 6500 FT DUE TO MODERATE TURB WHICH WAS INCREASING. CALLED 121.5 AND GAVE MAYDAY STATING VFR PLT IN IMC CONDITIONS NEED VECTORS TO NEAREST ARPT. NO REPLY TO MAYDAY. SWITCHED TO 122.0 AND REPEATED MAYDAY. NO REPLY. TRIED NAVING TO HOME ARPT BUT COULDN'T HOLD A HDG AND KEEP THE WINGS LEVEL. NEXT DECISION WAS TO DSND. SET UP FOR GPS APCH AND CONTACTED CTAF. UNICOM CAME ON AND ADVISED VISIBILITY WAS IMPROVING ON GND. FOLLOWED GPS APCH AND BROKE CLR OF CLOUDS WITH VISUAL OF RWY. LANDED PLANE WITHOUT INCIDENT.
