SINGLE PLT 'VFR' IN 'IMC.

Narrative

THE EVENT THAT OCCURRED WAS THE RAPID DEGRADATION OF THE WX FROM GOOD VFR TO IMC. THE TEMP AND DEWPOINT WERE BOTH 10/10; AND I SHOULD HAVE DELAYED THE FLT TO SEE IF THE VFR WOULD HOLD OUT. SINCE IT WAS A LCL VFR FLT; I DID NOT RECEIVE A THOROUGH BRIEFING; WHICH WAS AN ERROR IN JUDGEMENT ON MY PART. I SIMPLY WENT BY MY ARPT'S METAR. THE FIRST 20 MINS OF THE FLT WAS GOOD VFR. I FLEW W; AND FOLLOWED I-95. PHL CLRED ME PAST THEIR ARPT; AND ONCE I PASSED RWY 35; I SAW SCATTERED; BROKEN CLOUDS A FW MI AHEAD (1400 FT). I ASKED PHL TO CLR ME TO THE N; WHICH WAS APPROVED; THEN I NOTICED SCATTERED TO BROKEN CLOUDS BELOW ME TO THE N; SO I ASKED PHL TO CLR ME TOWARDS THE E; AND BACK TO PNE. IT WAS APPROVED. I STAYED AT 12000 FT; ABOVE THE CLOUDS; AND COULDN'T SEE THE ARPT. I STAYED ON RWY HEADING; 060 DEGS; AND TOLD PNE I COULDN'T SEE THE ARPT. PNE SAID THEY WOULD CALL PHL APCH; IF I WANTED TO SHOOT ILS RWY 24. SINCE THE ACFT WAS INST CERTIFIED; AND I WAS (CURRENT) ON INSTS; I ACCEPTED THE OFFER. I SHOT THE APCH TO ABOUT 80 FT OVER MINIMUMS; AND MISSED. PNE GAVE 270 DEGS AND 2000 FT AND SWITCHED ME TO PHL. PHL HAD ME HOLD AT PNE VOR. PHL SAID IF WE COULD KEEP HOLDING FOR A FEW MINS; THEY COULD VECTOR US FOR ILS RWY 17; THAT THEY WERE 900 FT BROKEN. I ACCEPTED THE OFFER; AND CONTINUED TO HOLD. ONCE ON THE VECTOR; I HAD THE LOC TUNED IN FOR RWY 17. I INTERCEPTED AT ABOUT 16 NM FROM PHL AT 4000 FT. I WAS SWITCHED TO TWR A FEW MI OUTSIDE THE MARKER. TWR ASKED IF I HAD THE PLATE; AND I TOLD THEM I DID NOT. THEY READ ME THE MINIMUMS; AND MISSED; AND I READ IT BACK. I BROKE OUT JUST UNDER 900 FT; LANDED AND TAXIED TO THE GA TERMINAL.
