SMA PLT ENCOUNTERS ICE ON IFR FLT PLAN. WHEN CLRED FOR LOWER; PLT IS TOLD HE WILL BE TOO LOW FOR RADAR COVERAGE. CTLR ISSUES A HDG WHICH DIRECTS HIM TOWARD A SMALL ARPT NEAR THE AIRWAY. AS HE DSNDS HE IS IN AND OUT OF CLOUDS BUT HAS SOME GND CONTACT AND BREAKS OUT ABOVE THE FIELD AND LANDS.

Narrative

ON AN IFR FLT PLAN FROM CGF TO FWA AT 4000 FT WE BEGAN TO PICK UP ICE. THERE WERE RPTS OF ICE AT 8000-10000 FT SO IT SEEMED WE SHOULD DSND. THE ICE FORECAST WAS WELL ABOVE OUR PLANNED FLT ALT AS WELL. WE ASKED FOR LOWER AND WERE CLRED FOR 3000 FT. ABOUT 40 MI FROM FWA WE BEGAN TO PICK UP ICE AGAIN. AGAIN WE ASKED FOR A LOWER ALT -- HOPING TO BREAK OUT SO WE COULD JUST LAND. THE CTLR GAVE US 2400 FT BUT SAID WE WOULD NO LONGER BE ON HIS SCOPE. A FEW MINS LATER HE ASKED ABOUT THE ICE. WE WERE IN AND OUT OF THE BOTTOMS; MORE IN THAN OUT. WE TOLD THE CTLR THE ICE WAS STILL THERE. WE HAD NOTICED ON THE ENRTE CHART THAT THERE WAS A SMALL ARPT JUST OFF THE AIRWAY. WHEN THE CTLR CLRED US TO 2400 FT; HE GAVE US A 10 DEG L TURN; WHICH SEEMED LIKE IT SHOULD PUT US OVER THE ARPT. IN FACT; THAT WAS WHAT HE HAD IN MIND. WHEN WE INFORMED HIM OF THE PERSISTENT ICE; HE SAID IF WE HAPPENED TO SEE THE ARPT; WE COULD LAND THERE; BUT HE COULDN'T GIVE US A CLRNC TO IT. AS WE GOT CLOSER; THE CTLR GAVE US SEVERAL HDGS TO PUT US OVER THE ARPT. WE WERE BREAKING IN AND OUT OF THE CLOUDS; OCCASIONALLY SEEING THE TWR BELOW US. WE BROKE OUT OF THE CLOUDS DIRECTLY OVER THE ARPT AND LANDED SAFELY. WE HAD PICKED UP ABOUT 1/8 - 1/4 INCH OF MIXED ICE. WE WOULD LIKE TO THANK THE CTLR FOR HELP IN WHAT COULD HAVE BEEN A MUCH WORSE SIT.
