BEFORE TAKEOFF, THE PLT RCVD A WX BRIEFING FOR THE PROPOSED ROUTE OF FLT. THIS INCLUDED INFO ABOUT THE FREEZING LVL (FORECAST AT 5000 FT) & A PRECAUTION FOR MODERATE ICING CONDS. THE BRIEFING DID NOT INCLUDE SIGMET LIMA 1 INFO ABOUT MODERATE TO SEVERE ICING CONDS, BUT THE SIGMENT WAS NOT VALID FOR THE PLT'S PROPOSED ROUTE OF FLT. HOWEVER, THE PLT RCVD CLNC FOR AN AMENDED ROUTE OF FLT, WHICH WENT THRU THE EDGE OF AN AREA DEFINED BY SIGMET LIMA 1. SHORTLY AFTER LEVELING AT 11,000', THE PLT RPRTD THE ACFT WAS IN ICING CONDS & WOULD NOT MAINTAIN ALTITUDE.

THE ACFT WAS NOT EQUIPPED FOR FLT IN KNOWN ICING CONDS.
