AN SMA LOST HIS FORMATION IN LOW CLOUDS AND LANDED WITHOUT PERMISSION AT A CTLED ARPT.

Narrative

WHILE AT NECEPAH ARPT WE GASSED OUR AIRPLANES AND HAD LUNCH. AFTER LUNCH WE WENT BACK TO THE ARPT AND CHKED WX. ACCORDING TO THE RPT THAT DAY; THE ARPTS S OF US WERE RPTING IMPROVING CONDITIONS. A CORPORATE PLANE THAT FLEW IN ALSO RPTED CONDITIONS IMPROVING S. WE WERE HEADED FOR BROADHEAD; WI. ON THE WAY; CEILING STARTED COMING DOWN SOME BUT VISIBILITY WASN'T BAD. JUST ABOVE MADISON THE CEILING REALLY DROPPED AND THE VISIBILITY WENT WAY DOWN. I WAS WATCHING THE PLANE IN FRONT OF ME AND IT DISAPPEARED. I COULDN'T SEE THE PLANE I WAS FOLLOWING TURN AROUND. WHEN VISIBILITY WENT DOWN; I WAS CONCENTRATING ON THE PLANE IN FRONT OF ME AND LOST MY PLACE ON THE MAP. NEXT THING I SAW WAS AN ARPT TO MY R. I KNEW FROM THE SIZE OF THE ARPT IT HAD TO BE CTLED. RATHER THAN TURN AROUND AND TRY TO FLY THROUGH THIS WX; I CHOSE TO LAND. I DIDN'T BOTHER TO CIRCLE THE TWR FOR FEAR I WOULD FLY IN FRONT OF TFC. NOT SEEING ANY TFC MOVING; I ELECTED TO MAKE AM EMER LNDG. I LANDED ON RWY 22 ON THE APCH APRON SLIGHTLY DOWNWIND; TURNED OFF INTO THE GRASS AND TAXIED TO AN FBO AND TIED THE AIRPLANE WHERE; AFTER A COUPLE OF MINS; I WAS GREETED BY MANY VEHICLES. FROM NOW ON I PLAN TO NOT FLY IN A GROUP IN MINIMAL CONDITIONS. SO I WILL BE DOING MY OWN NAV; AND WILL BE GIVING EXTRA CONSIDERATION ABOUT EVEN FLYING IN SUCH CONDITIONS.
