A PVT PLT FLYING A C152 AT BDR RPTS FAILING TO HOLD SHORT OF AN ACTIVE RWY AFTER BECOMING CONFUSED ABOUT HIS TAXI CLRNC.

Narrative

AFTER TOUCHING DOWN AT BDR; THE TWR TOLD ME TO STAY ON HIS FREQ AND TURN L ONTO TXWY H. I THEN TOLD HIM THAT I WOULD LIKE TO RETURN TO THE ACTIVE FOR TKOF. HE THEN INSTRUCTED ME TO TURN FROM TXWY H TO TXWY A TO RETURN TO RWY 29. AFTER TURNING ONTO TXWY A; I BEGAN TO PREPARE FOR TKOF. IT MUST BE POINTED OUT THAT I WAS NOT FAMILIAR WITH THIS ARPT. CONFUSED ABOUT WHERE I SHOULD BE; I CAME TO A FULL STOP; AND WAS ABOUT TO CONTACT THE TWR FOR CLRER INSTRUCTIONS. AT THAT POINT; THE TWR INSTRUCTED AN ACFT ON FINAL TO GO AROUND. HE THEN INFORMED ME THAT I WAS BEYOND THE TXWY THRESHOLD. LOOKING BACK; ONLY THEN DID I SEE THE YELLOW HOLD LINES; A FULL FUSELAGE-LENGTH BACK. I IMMEDIATELY STATED THAT I WOULD TAXI BACK BEYOND THE LINES PROMPTLY. (I ALSO MUST POINT OUT THAT THESE HOLD LINES CONSISTED OF OLD; FADED PAINT UPON HIGHLY WEATHERED ASPHALT; IE; VERY EASY TO MISS.) THE TWR THEN INSTRUCTED ME TO HOLD MY POS; COPY THE TWR PHONE NUMBER; CALL THE TWR WHEN I REACHED MY DEST; AND CLRED ME FOR TKOF. LATER; WHEN I CALLED THE TWR; THE CTLR TOLD ME THAT I HAD COMMITTED A RWY INCURSION AND THAT HE INTENDED TO RPT ME TO THE FAA. AT THIS POINT I ALSO MUST POINT OUT THAT AT THE TIME OF THE INCIDENT; ALTHOUGH I WAS BEYOND THE THRESHOLD MARKINGS AND CONSIDERED IN THE RWY AREA; AT NO TIME WAS I ACTUALLY ON THE RWY ITSELF. THE PLANE ON FINAL WAS NOT IN DANGER OF COLLISION; AND COULD EASILY HAVE LANDED WITHOUT INCIDENT. ON THE PHONE; THE CTLR ACTUALLY APOLOGIZED TO ME; STATING THAT HE WAS COMPELLED TO TAKE ACTION BECAUSE OF STRINGENT ENFORCEMENT FROM ABOVE AND THAT HE FEARED FOR HIS JOB. IN OTHER WORDS; HIS ACTION WAS BASED PURELY ON PROTOCOL; NOT BECAUSE OF AN EMER OR HAZARDOUS SIT. THE OTHER ACFT WAS FLYING VFR IN VMC; PRACTICING TOUCH-AND-GOES. I BELIEVE THAT SEVERAL FACTORS CONTRIBUTED TO THIS INCIDENT. FIRST WAS THAT I WAS NOT FAMILIAR WITH THE ARPT LAYOUT. AS FOR SIGNS; I CANNOT REMEMBER THEM. USUALLY FOR THRESHOLDS; I LOOK FOR PAINTED LINES FIRST; THEN SIGNS SECONDARY; IE; TAIL/ILS HOLD; DISPLACED RWY THRESHOLDS; ETC. I CANNOT RECALL IF THERE WERE SIGNS OR NOT. FINALLY; COMS WAS A FACTOR. I DID NOT UNDERSTAND IF 'TAXI TO RWY 29' MEANT ENTERING RWY 29 FOR A 'BACK TAXI' OR NOT. CALLING FOR A REPEAT OF INSTRUCTIONS AND/OR A PROGRESSIVE TAXI WAS PRUDENT; AND I HAD INTENDED TO DO SO. HOWEVER; I BELIEVED AT THAT MOMENT THAT I WAS STILL ON A TXWY -- NOT THE RWY AREA. ONE LAST REASON WHY I HADN'T COMMUNICATED SOONER WAS THAT THERE WAS NO GND CTL. THE TWR WAS CTLING EVERYTHING AND I WAS WAITING FOR A BREAK IN COMS WITH OTHER ACFT. I HAD NO INTENTION OF ENTERING WHAT I BELIEVED WAS THE RWY WITHOUT CONCISE CLRNC FROM THE TWR.
