BE10 LANDS BELOW MINIMUMS AT LNS.

Narrative

THE FLT ORIGINATED AT THE CHESTERFIELD COUNTY ARPT IN A KING AIR B100; PROCEEDED OVER THE RICHMOND ARPT TO PICK UP PAX AND ON TO LANCASTER. LEAVING THE RICHMOND ARPT; THE WX IN LANCASTER WAS 100 FT OVCST AND 1/4 MI VISIBILITY AND FOG. THE FORECAST IN THE LANCASTER AREA WAS EXPECTED TO IMPROVE ABOVE MINIMUMS BY THE TIME I REACHED THERE AN HR LATER. ALSO; BOTH BALTIMORE AND HARRISONBURG WERE ABOVE MINIMUMS AND COULD BE USED AS AN ALTERNATE. WHEN I WAS WITHIN 50 MI OF LNS; I TRIED TO PICK UP THE ATIS RPT; BUT DUE TO SOME FEEDBACK ON THE FREQ; I WAS ONLY ABLE TO UNDERSTAND 8 MI VISIBILITY AND THE WINDS; WHICH WERE NOW 6 KTS. AT ABOUT THE SAME TIME I WAS HANDED OVER TO HARRISONBURG APCH. ON THE FIRST CONTACT; I ASKED IF EVERYONE WAS MAKING IT INTO LANCASTER THAT MORNING. THE CTLR TOLD ME THAT A LEAR 31 WAS 3 MI OUT ON THE ILS AND A KING AIR 90 WAS LINING UP BEHIND HIM; AND THEY WERE THE FIRST TO TRY. I STARTED TO RECEIVE VECTORS FOR THE ILS 8 INTO LNS; AND BEGAN SETTING UP THE ACFT FOR THE APCH. AFTER A FEW MINS THE LEAR 31 HAD LANDED AND SAID THAT HE BROKE OUT AT MINIMUMS. THE KING AIR BEHIND HIM ALSO BROKE OUT AT MINIMUMS. BY THIS TIME I WAS ON THE LOC ABOUT 1 MI FROM THE FAF. I WAS THEN HANDED OVER TO THE TWR AND CLRED TO LAND. AT 200 FT AGL I PICKED UP THE RABBIT LIGHTS; AND CONTINUED WITH THE APCH. THEN AT 150 FT AGL I PICKED UP THE RWY LIGHTS AND LANDED. ONCE I WAS CLR OF THE RWY I GAVE THE SAME PIREP AS THE OTHER ACFT STATING THAT THE WX WAS 1/2 MI VISIBILITY AND 200 FT OVCST. THE GND CTLR THEN TOLD ME THAT THE ATIS WAS SAYING 1/8 MI VISIBILITY AND OBSCURED. APPARENTLY THE '8' I HEARD ON THE RADIO WAS ACTUALLY 1/8; AND THAT ACCORDING TO PART 135 REGS I SHOULD HAVE NEVER STARTED THE APCH BECAUSE OF THE WX. I FEEL THE LNDG WAS LEGAL BUT THAT THE APCH SHOULD NOT HAVE BEEN STATED. I FEEL THAT THE CONTRIBUTING FACTORS TO THIS WERE THE GARBLED ATIS FREQ; AND THE FACT THAT I DID NOT FOLLOW UP WITH THE CTLRS TO GET THE FULL WX BRIEFING. ALSO; HEARING THE OTHER PLANES LAND AHEAD OF ME; SOMEHOW GAVE ME THE CONFIDENCE TO CONTINUE THE APCH. UPON RETURNING TO RICHMOND; I CALLED OUR LCL FAA REPRESENTATIVE AND EXPLAINED THE INCIDENT. WE DISCUSSED THE APCH AND LNDG COMING TO THE SAME CONCLUSION AS ABOVE. IN THE FUTURE I WILL ALWAYS MAKE SURE I HAVE A COMPLETE WX PICTURE BEFORE ATTEMPTING AN APCH.
