Narrative:

On an evening flight from ack to bed, we may have flown into conditions that may have been considered to be 'flight conditions of known or potential icing.' the aircraft, a cessna 182RG, is not certified for flight into conditions of known icing. Both pilots were commercial pilots with instrument ratings (in currency) with 320 plus hours total time each and are familiar with flying in the greater boston and massachusetts area. The training flight departed bed at XA30 local in VFR conditions. The ceiling to avck en route was 6000 ft with 10 mi visibility. En route to ack we encountered light snow showers at the filed altitude of 5000 ft. Other aircraft also reported similar conditions. There were no reported PIREPS for icing conditions in the area and en route to ack. The flight terminated at ack at approximately XB30. En route, the aircraft was continuously checked for any icing or snow accumulation, in which there was none. Outside air temperature was 20 degrees F. At approximately XC30 we received a thorough WX briefing. The WX at the time was ack 15 broken 6 KTS, wind 6 degrees at 6 KTS, light snow showers. Bed was 100 ft overcast 10 KTS, wind 12 degrees 10 KTS. Cloud layers reported at 15-35 broken and from 40-60 broken clear above. A band of snow showers was west of bed northeast of burlington, vt, to the keane, vt, area moving southeast. Both instrument flight plans were filed in my name whereas I was not PIC during both flts. The air temperature at ack was 25 degrees F and the aircraft was covered lightly with some light puffy snow (it was not wet). There were light snow showers at ack at the time of departure. We decided to takeoff after cleaning the aircraft and receiving our IFR clearance. No snow or ice was on the aircraft. En route to bed we were in and out of the clouds at flight altitude of 4000 ft MSL. The WX was scattered clouds at 3000 ft to 6000 ft MSL and a layer above at approximately 10000 ft MSL and we encountered light snow showers. ATC requested flight conditions, several times. Visibility improved to 10 plus NM as we got closer to bed and again no ice or snow accumulated on the aircraft. We believe the snow flurries were 'flaky' due to the fact that the humidity was low and the air (and aircraft surfaces) were very cold. The flight terminated at bed at approximately XD30 in visual conditions.

Title: ENRTE WX FORECAST WITH POSSIBLE ICING.

Narrative: ON AN EVENING FLT FROM ACK TO BED, WE MAY HAVE FLOWN INTO CONDITIONS THAT MAY HAVE BEEN CONSIDERED TO BE 'FLT CONDITIONS OF KNOWN OR POTENTIAL ICING.' THE ACFT, A CESSNA 182RG, IS NOT CERTIFIED FOR FLT INTO CONDITIONS OF KNOWN ICING. BOTH PLTS WERE COMMERCIAL PLTS WITH INST RATINGS (IN CURRENCY) WITH 320 PLUS HRS TOTAL TIME EACH AND ARE FAMILIAR WITH FLYING IN THE GREATER BOSTON AND MASSACHUSETTS AREA. THE TRAINING FLT DEPARTED BED AT XA30 LCL IN VFR CONDITIONS. THE CEILING TO AVCK ENRTE WAS 6000 FT WITH 10 MI VISIBILITY. ENRTE TO ACK WE ENCOUNTERED LIGHT SNOW SHOWERS AT THE FILED ALT OF 5000 FT. OTHER ACFT ALSO RPTED SIMILAR CONDITIONS. THERE WERE NO RPTED PIREPS FOR ICING CONDITIONS IN THE AREA AND ENRTE TO ACK. THE FLT TERMINATED AT ACK AT APPROX XB30. ENRTE, THE ACFT WAS CONTINUOUSLY CHKED FOR ANY ICING OR SNOW ACCUMULATION, IN WHICH THERE WAS NONE. OUTSIDE AIR TEMP WAS 20 DEGS F. AT APPROX XC30 WE RECEIVED A THOROUGH WX BRIEFING. THE WX AT THE TIME WAS ACK 15 BROKEN 6 KTS, WIND 6 DEGS AT 6 KTS, LIGHT SNOW SHOWERS. BED WAS 100 FT OVCST 10 KTS, WIND 12 DEGS 10 KTS. CLOUD LAYERS RPTED AT 15-35 BROKEN AND FROM 40-60 BROKEN CLR ABOVE. A BAND OF SNOW SHOWERS WAS W OF BED NE OF BURLINGTON, VT, TO THE KEANE, VT, AREA MOVING SE. BOTH INST FLT PLANS WERE FILED IN MY NAME WHEREAS I WAS NOT PIC DURING BOTH FLTS. THE AIR TEMP AT ACK WAS 25 DEGS F AND THE ACFT WAS COVERED LIGHTLY WITH SOME LIGHT PUFFY SNOW (IT WAS NOT WET). THERE WERE LIGHT SNOW SHOWERS AT ACK AT THE TIME OF DEP. WE DECIDED TO TKOF AFTER CLEANING THE ACFT AND RECEIVING OUR IFR CLRNC. NO SNOW OR ICE WAS ON THE ACFT. ENRTE TO BED WE WERE IN AND OUT OF THE CLOUDS AT FLT ALT OF 4000 FT MSL. THE WX WAS SCATTERED CLOUDS AT 3000 FT TO 6000 FT MSL AND A LAYER ABOVE AT APPROX 10000 FT MSL AND WE ENCOUNTERED LIGHT SNOW SHOWERS. ATC REQUESTED FLT CONDITIONS, SEVERAL TIMES. VISIBILITY IMPROVED TO 10 PLUS NM AS WE GOT CLOSER TO BED AND AGAIN NO ICE OR SNOW ACCUMULATED ON THE ACFT. WE BELIEVE THE SNOW FLURRIES WERE 'FLAKY' DUE TO THE FACT THAT THE HUMIDITY WAS LOW AND THE AIR (AND ACFT SURFACES) WERE VERY COLD. THE FLT TERMINATED AT BED AT APPROX XD30 IN VISUAL CONDITIONS.
