Narrative:
Contributing factor: lack of basic aeronautical knowledge and common sense by pilot/crew of small aircraft, aircraft Y. VFR flight in IMC conditions. In solid cloud moderate turbulence, heavy snow, moderate mixed icing. Reporting pilot: pilot of military small transport, aircraft X on IFR clearance, IFR in solid IMC conditions, cleared to descend from 11000 ft to 9000 ft and then 9000 ft to 4000 ft. Received several advisories about VFR traffic small aircraft X at 8500 ft. We were solid IMC on the entire descent, not between layers, in moderate mixed icing. New york approach (132.25) advised the small aircraft X was 3 mi and reaffirmed the pilot stated he was VFR at 8500 ft on V308. An light transport, aircraft Z, also questioned the controller about VFR traffic at 8500 ft. There is no issue with air traffic. The problem is with the small aircraft pilot that does not know cloud clearance and visibility requirements for VFR flight in controled airspace. When I called the sardi sector controller (ZBW 132.30) and he also had stated that other pilot complained about VFR traffic at 8500 ft. Time and location of incident apr/sat/93, late am, about 35 mi southwest of hampton VOR. Note: the break in the descent at 9000 ft was because of the 'VFR' target at 8500 ft!

Title: A MIL SMT PLT RPTS THAT AN SMA WAS VFR IN HARD IMC WITH ICING AND TURB.
Narrative: CONTRIBUTING FACTOR: LACK OF BASIC AERO KNOWLEDGE AND COMMON SENSE BY PLT/CREW OF SMA, ACFT Y. VFR FLT IN IMC CONDITIONS. IN SOLID CLOUD MODERATE TURB, HVY SNOW, MODERATE MIXED ICING. RPTING PLT: PLT OF MIL SMT, ACFT X ON IFR CLRNC, IFR IN SOLID IMC CONDITIONS, CLRED TO DSND FROM 11000 FT TO 9000 FT AND THEN 9000 FT TO 4000 FT. RECEIVED SEVERAL ADVISORIES ABOUT VFR TFC SMA X AT 8500 FT. WE WERE SOLID IMC ON THE ENTIRE DSCNT, NOT BTWN LAYERS, IN MODERATE MIXED ICING. NEW YORK APCH (132.25) ADVISED THE SMA X WAS 3 MI AND REAFFIRMED THE PLT STATED HE WAS VFR AT 8500 FT ON V308. AN LTT, ACFT Z, ALSO QUESTIONED THE CTLR ABOUT VFR TFC AT 8500 FT. THERE IS NO ISSUE WITH AIR TFC. THE PROB IS WITH THE SMA PLT THAT DOES NOT KNOW CLOUD CLRNC AND VISIBILITY REQUIREMENTS FOR VFR FLT IN CTLED AIRSPACE. WHEN I CALLED THE SARDI SECTOR CTLR (ZBW 132.30) AND HE ALSO HAD STATED THAT OTHER PLT COMPLAINED ABOUT VFR TFC AT 8500 FT. TIME AND LOCATION OF INCIDENT APR/SAT/93, LATE AM, ABOUT 35 MI SW OF HAMPTON VOR. NOTE: THE BREAK IN THE DSCNT AT 9000 FT WAS BECAUSE OF THE 'VFR' TARGET AT 8500 FT!
