A C172 PLT; ON APCH TO PNS; DID NOT FOLLOW CHARTED MISSED APCH PROCS.

Narrative

AT ABOUT THE TIME I WANTED TO RETURN TO PNS; THERE WERE 10 ACFT FOR THE ILS. I WAS TOLD TO WAIT; THEN I WAS TURNED N FOR THE APCH. I WAS VECTORED 10 MI TO THE N OF PNS; WHERE IT WAS CLR; BUT I HEARD ATC AND OTHER PLTS TALK ABOUT THE CEILING DECREASING -- 500 FT; 300 FT; THEN 200 FT. MIST HAD QUICKLY DEVELOPED OVER PNS FIELD. I WAS CLRED FOR THE ILS RWY 17 APCH; AND TOLD TO SLOW. I SLOWED FROM 90 KTS TO 70 KTS. I WAS TOLD I WOULD BE CLRED TO LAND; AFTER THE ACFT AHEAD LANDED. THE TWR DIRECTED THE ACFT AHEAD TO TURN AT THE NEXT TXWY; THEN IT BECAME APPARENT HE HADN'T LANDED. I FOUND MYSELF AT THE MIDDLE MARKER; AND THE TWR TOLD ME TO GO AROUND. I APPLIED PWR; CLEANED UP THE FLAPS. I NEVER GOT OUT OF IMC. CLBED TO 600 FT; THEN MADE A CLBING L TURN. I HAD TURNED FROM A HDG OF 165 DEGS TO ALMOST 030 DEGS; WHEN THE TWR TOLD ME TO FLY RWY HDG. I RESPONDED THAT I WAS TURNING AS PUBLISHED; AND THE TWR TOLD ME FLY HDG 090 DEGS; CLB TO 1700 FT AND CONTACT THE APCH CTLR; WHICH I DID. JUST THEN; I REALIZED THAT THE PUBLISHED MISSED APCH IS A CLBING R TURN; TO NUN VOR! (I HAD TURNED L.) THE CTLR BROUGHT ME AROUND AGAIN; AND I MADE THE APCH IN THE MIST; 200 FT CEILING; 1/2 MI VISIBILITY; BUT NO ACFT TRYING TO LAND JUST AHEAD OF ME. FACTORS: 1) PNS IS MY HOME ARPT. I'VE FLOWN THE ILS RWY 17 APCH HUNDREDS OF TIMES. I HAD HIGH CONFIDENCE THAT I KNEW THE APCH. 2) WHEN DOING PRACTICE APCHS; THE GAR INSTRUCTIONS ARE MORE OFTEN FOR A CLBING L TURN; SO WHEN I WAS TOLD TO DO A GAR; I IMMEDIATELY THOUGHT OF A CLBING L TURN. 3) WHEN I WAS BEING VECTORED; I WAS THINKING IT WOULD BE A QUICK EASY ILS; WITH CLOUDS FROM 1700 FT TO 800 FT OR 700 FT. I WASN'T MENTALLY PREPARED FOR THE SUDDEN CEILING DROP TO 200 FT. WHEN I HEARD ABOUT THIS; I WAS ON THE LOC AND BUSY LINING UP THE AIRPLANE. 4) MOST OF MY ATTN WAS FLYING THE AIRPLANE ON THE LOC AND GS TO THE MINIMUMS. WHAT ATTN I HAD LEFT WAS TRYING TO FIGURE IF THE AIRPLANE AHEAD WOULD BE OFF THE RWY BY THE TIME I TOUCHED DOWN. 5) ATC WAS TRYING TO GET SEVERAL AIRPLANES IN; SO SPACING ON THE ILS WAS TIGHTER THAN USUAL. CORRECTIVE ACTIONS: 1) ALWAYS EXPECT AND MENTALLY PREPARE FOR SUDDEN WORSENING OF WX AND RAPIDLY CHANGING TFC SITS. 2) MAKE SURE I READ TO MYSELF THE MISSED APCH PROCS EACH TIME -- ESPECIALLY IF I'M FAMILIAR WITH THE APCH. (THAT IS; STUDY EVERYTHING ON A FAMILIAR APCH AS I WOULD ON AN UNFAMILIAR APCH).
