TAILWHEEL ACFT FLIPPED OVER ON ITS BACK AFTER LNDG.

Narrative

TAXIING FROM THE N RWY AT TOK JUNCTION; AK; I TRIED TO TURN R TO BACK TAXI DOWN RWY 7; BUT DIDN'T MAKE THE TURN BECAUSE OF ICE. AFTER TAKING OFF AT XA10 UTC; I STARTED FOLLOWING THE AK HWY SE OUT OF TOK JUNCTION AND STARTED A SLOW CLB. I OPENED MY FLT PLAN WITH NORTHWAY FSS 1 MI SE OF TOK JUNCTION. THE VISIBILITY WAS 1 MI AND AT 2500 FT I STARTED TO LOSE SIGHT OF THE ROAD AND STILL HADN'T COME OUT OF THE FOG (ABOUT 1000 FT AGL). AT THIS POINT I NOTICED ICE ON THE WINDSHIELD; WHICH I HADN'T NOTICED BEFORE BECAUSE OF THE FOG. I IMMEDIATELY TURNED AROUND AND FOLLOWED THE ROAD BACK TO TOK JUNCTION. I NOTIFIED NORTHWAY FSS 2 OR 3 MI SE OF TOK THAT I WAS RETURNING AND THEY CLOSED MY FLT PLAN. I FLEW A L DOWNWIND FOR RWY 7 ALONG THE AK HWY (ABOUT 1/2 MI FROM RWY) AT 2100 FT MSL (500 FT AGL); AND COMPLETED THE PRELNDG CHKLIST. ABEAM THE END OF THE RWY I SLOWED TO THE TOP OF THE WHITE ARC (77 MPH). I PUT IN FULL FLAPS ON BASE AND KEPT MY SPD AT THE TOP OF THE WHITE ARC UNTIL I WAS A COUPLE HUNDRED FT FROM THE RWY THRESHOLD. AT THAT POINT I BEGAN REDUCING PWR AND FLARING FOR THE LNDG. AT THE END OF THE RWY THE THROTTLE WAS FULLY CLOSED. I FLOATED ABOUT 300 FT DOWN THE RWY AND TOUCHED DOWN ON THE MAIN WHEELS FIRST. I WAS LOOKING THROUGH A FEW INCHES OF CLR WINDSHIELD BTWN THE ICE AND VERT WINDSHIELD FRAME DURING APCH AND LNDG. THE TOUCHDOWN WAS FAIRLY SOFT; BUT THE TAIL CAME DOWN AND I BEGAN PORPOISING. I BOUNCED ABOUT 4 TIMES AND TRIED TO CORRECT WITH THE ELEVATOR. AFTER ABOUT 4 BOUNCES I RAISED THE FLAPS AND THE BOUNCING SETTLED OUT. ABOUT 2 SECONDS AFTER I STOPPED BOUNCING; I BEGAN TO SLIDE TO THE R. I APPLIED L RUDDER AND SLOWLY INCREASED IT; BUT WE SLID OFF INTO DEEP SNOW AND FLIPPED OVER. THE PLANE WAS GOING STRAIGHT WHEN IT SLID OFF (NOT SIDEWAYS). SPECIFIC THINGS THAT I SHOULD HAVE DONE WERE TO OPEN THE DOOR INFLT; REACH AROUND AND SCRAPE THE ICE OFF THE WINDSHIELD; MAKE A WIDER BASE THAN 1/2 MI; AND RAISE THE FLAPS IMMEDIATELY AFTER TOUCHDOWN. THE PLANE WANTS TO FLAT (OR BOUNCE) IF THE FLAPS ARE LEFT DOWN. MY BIGGEST MISTAKE; I THINK; WAS NOT GOING AROUND AFTER THE FIRST BOUNCE. CONTRIBUTING FACTORS WERE MY LACK OF RECENT EXPERIENCE. I HAD ONLY FLOWN ABOUT 15 HRS IN THE PAST 3 MONTHS; AND ONLY 5 TKOFS/LNDGS IN A TAILWHEEL. I WAS ALSO RUSHING BECAUSE DAYLIGHT WAS CRITICAL TO MAKE IT TO WHITEHORSE; CANADA; AND FOR SOME REASON I DIDN'T GET OUT OF MY RUSH MODE AFTER TURNING AROUND. I HAD VERY LITTLE EXPERIENCE WITH ICING; HAVING PICKED UP LIGHT RIME ONCE BEFORE; WHICH DISAPPEARED AFTER CLBING. THIS ICE WAS THICKER; ALTHOUGH NOT CLR ICE. THE TEMP ON THE SURFACE WAS MINUS 18 DEGS F; SO I DIDN'T WATCH CLOSELY FOR ICE. ON BASE; THE THOUGHT WENT THROUGH MY MIND THAT I SHOULD TRY TO GET THE ICE OFF THE WINDSHIELD; BUT I DECIDED THAT I COULD HANDLE THE LNDG BY LOOKING OUT THE SIDE.
