IFR M20 PLT AT 16000 FT ENCOUNTERED WX; BECAME DISORIENTED; CHANGED HDG AND ALT; ENCOUNTERED ICING AND DECLARED AN EMER.

Narrative

I WAS ON AN IFR FLT PLAN. I WAS ASSIGNED 16000 FT BY ATC. THERE WERE NO CLOUDS NEARBY BUT I DID SEE THAT THE MOUNTAIN TOPS WERE OBSCURED TO THE W OF MY LOCATION. I WAS EXPERIENCING VERY STRONG HEADWINDS. I HAD MADE THE TURN TO DIRECT AND COULD SEE THAT I WOULD BE STARTING TO ENTER THE CLOUDS SHORTLY. I AM A NEW INST PLT AND I WAS A LITTLE NERVOUS AS THIS WOULD BE MY FIRST REAL ACTUAL FLT IN IMC. JUST PRIOR TO THE VOR; I STARTED TO EXPERIENCE WHAT I THOUGHT WAS A MOUNTAIN WAVE. THE NOSE OF THE ACFT WAS PITCHING UP TO ALMOST VERT AND MY GND SPD HAD DROPPED TO AN INDICATED 30 KIAS ON THE GPS. I TRIED TO PUSH THE NOSE OVER AND I STARTED TO ENTER THE CLOUD. THIS ALSO WAS HAPPENING AT ABOUT THE SAME TIME AS THE COURSE CHANGE WAS GIVEN TO ME TO GO DIRECT TO NEXT VOR. I WAS TRYING TO CHANGE COURSE AND CHANGE THE GPS WHEN I GOT TURNED AROUND IN THE CLOUD. I STARTED A STEEP DSCNT AND LOST ABOUT 2000 FT BEFORE I WAS ABLE TO STABILIZE THE PLANE. ATC WAS TRYING TO CONTACT ME AND I JUST HAD TIME TO TELL THEM THAT I WAS DISORIENTED. THEY ASKED IF I WANTED TO DECLARE AN EMER AND I SAID YES. I WAS JUST STARTING TO GET THINGS UNDER CTL AGAIN AND I WAS HANDED OFF TO ANOTHER CTLR. I WAS TRYING TO CALL THE NEXT CTLR BUT WAS NOT ABLE TO MAKE RADIO CONTACT. I HAD BEEN CLRED TO CLB TO 17000 FT SO I COULD GET OUT OF THE CLOUD BY THE PREVIOUS CTLR. I WAS TRYING TO CLB AND CALL THE NEW CTLR WHEN THE ENG STARTED TO RUN ROUGH. I STARTED TO LOSE PWR AND STARTED TO DSND AGAIN (CARB ICING; I PULLED ON THE CARB HEAT AND IT FINALLY STARTED TO RUN OK AGAIN). I WAS ALSO STARTING TO PICK UP ICE ON THE WINDSCREEN AND THE LEADING EDGES OF THE CTL SURFACES. I STILL WAS NOT ABLE TO CONTACT THE CTLR; SO I SWITCHED BACK TO THE LAST CTLR I WAS TALKING TO. I WAS ABLE TO TALK TO HIM AND TOLD HIM ABOUT THE NEW PROBS. HE ASKED WHAT I WANTED TO DO. I TOLD HIM THAT I NEEDED TO GET DOWN OUT OF THE ICE. I WAS NOT ABLE TO CLB AND I WAS IN AN AREA WHERE THE MEA WAS 16000 FT MSL AND I COULD BARELY MAINTAIN 14000 FT. WITH THE HELP OF 2 ACR PLTS; THE CTLR WAS ABLE TO GET ME HEADED TOWARD ZZZ WHERE IT WAS CLR. THE RADIO COVERAGE IN THIS AREA (AT THE ALTS I WAS AT) IS REALLY BAD AND WITHOUT THE HELP OF THE AIRLINES RELAYING THE VECTORS; I WOULD HAVE HAD A MUCH HARDER TIME GETTING OUT OF THE SITUATION I WAS IN. BY THE TIME I WAS HANDED OFF TO APCH; I WAS ABLE TO GET A LOWER ALT AND THE ICE STARTED COMING OFF. THERE WAS ABOUT 2-3 INCHES OF ICE ON THE LEADING EDGE OF THE WINGS. BY THE TIME I WAS CLRED TO LAND; THE ICE WAS GONE AND I HAD CALMED DOWN A LITTLE; HOWEVER; I WAS STILL CONCENTRATING SO HARD ABOUT FLYING THAT I FORGOT TO GET THE RADIO FREQS FOR THE ARPT OUT. I LANDED A LITTLE LONG AND THE TWR CTLR HAD ME TURN OFF AND THEN SWITCH TO GND BUT HE ONLY TOLD ME .7. I STOPPED AFTER XING THE HOLD SHORT LINES ON THE RAMP'S SIDE OF THE LINE TO LOOK UP THE RIGHT GND FREQ. BY THE TIME I GOT THAT INTO THE RADIO; A COMMUTER AIRLINER WAS SITTING BEHIND ME AND THE GND CTLR WAS YELLING OVER THE RADIO FOR ME TO MOVE. I GOT PARKED ON THE RAMP AND I WAS TOLD TO CALL CENTER AND SPEAK TO SUPVR. I CALLED AND SPOKE TO THE SUPVR AND THANKED HIM AND THE CTLRS FOR GETTING ME OUT OF A BAD SITUATION. THE CTR CTLRS WERE VERY HELPFUL AND PROFESSIONAL. THE ARPT PERSONNEL I DEALT WITH WERE A DIFFERENT STORY; EXCEPT FOR THE CTLR WORKING APCH (HE WAS VERY HELPFUL AND TRIED HIS BEST TO GET ME RELAXED AND GET THE ICE OFF BEFORE I TRIED TO LAND). THE ARPT CTLRS SEEM AS IF EVERYTHING GOING ON AT THE ARPT WAS A PROB FOR THEM AND WERE CONSTANTLY YELLING AND MAKING RUDE REMARKS ON THE RADIO NOT JUST TO ME BUT TO JUST ABOUT EVERYONE THERE.
