Narrative:

Due to icing, I was flying, with permission, around clouds. I thought I was cleared to 16000 ft. Then I heard 'I need you at 13000 ft for traffic.' I must have been at 13500 ft. I began to descend. I had the traffic in sight. He then cleared me for FL220. Later he called me and said I broke minimums. I was circling to climb earlier to avoid icing. The controller should have told me to circle where I was. But there was no conflict anyway with traffic since I could see it anyway. Did the first controller in atlanta not tell the second one about the icing problem? Had I begun to build ice, I would have turned around immediately. Winter flying, without anti-ice is tough enough. We need the controller's help.

Title: THE PVT PLT OF A LANCAIR IVP CLBED ABOVE HIS ASSIGNED ALT WHILE MANEUVERING TO AVOID CLOUDS AND ICING.

Narrative: DUE TO ICING, I WAS FLYING, WITH PERMISSION, AROUND CLOUDS. I THOUGHT I WAS CLRED TO 16000 FT. THEN I HEARD 'I NEED YOU AT 13000 FT FOR TFC.' I MUST HAVE BEEN AT 13500 FT. I BEGAN TO DSND. I HAD THE TFC IN SIGHT. HE THEN CLRED ME FOR FL220. LATER HE CALLED ME AND SAID I BROKE MINIMUMS. I WAS CIRCLING TO CLB EARLIER TO AVOID ICING. THE CTLR SHOULD HAVE TOLD ME TO CIRCLE WHERE I WAS. BUT THERE WAS NO CONFLICT ANYWAY WITH TFC SINCE I COULD SEE IT ANYWAY. DID THE FIRST CTLR IN ATLANTA NOT TELL THE SECOND ONE ABOUT THE ICING PROB? HAD I BEGUN TO BUILD ICE, I WOULD HAVE TURNED AROUND IMMEDIATELY. WINTER FLYING, WITHOUT ANTI-ICE IS TOUGH ENOUGH. WE NEED THE CTLR'S HELP.
