PLT OF A SMA SEL MAKES INADVERTENT TKOF ON TXWY.

Narrative

WHAT REALLY CAUSED PROB WAS LACK OF ATTN BY GND CTL TO TAXIING ACFT. IF I MADE THE ALLEGED TKOF ON TXWY ALPHA SERVING RWY 17L; IT WAS DUE TO THE ABSENCE OF PROPER SEQUENTIAL TAXIING INSTRUCTIONS FROM GND CTL. TO BE INFORMED OF AN ALLEGED TKOF SOME APPROX 14 DAYS LATER BY PHONE CALL SEEMS UNUSUAL. I DO NOT BELIEVE I WAS INFORMED AT THE TIME OF ACTION. I BELIEVE GND CTL; TWR AND DEP CTL WERE ALL THE SAME VOICE. FOR SAFETY EVALUATION; BASED ON MY MEMORY AND GND CTL RADIO INSTRUCTION TO PLTS; I WAS THE ONLY ACFT ACTIVE ON THE GND IN THE ARPT ENVIRONMENT. I DO CARE TO HELP GND CTL CLARIFY INSTRUCTIONS TO TAXIING PLTS; FOR MY OWN SAFETY AND OTHERS. I SHOULD HAVE BEEN STOPPED VIA GND RADAR OBSERVATION OR VISUAL OBSERVATION WHEN ANY IMPROPER TURN WAS MADE. IT WOULD HELP ME WITH MY SEE AND AVOID RESPONSIBILITY. GND CTL WAS NOTIFIED WITH ADIS ALERT SAID THE RWY AREA WAS UNDER CONSTRUCTION WITH A 1000 FT DISPLACED THRESHOLD. GND CTL SAID I HAD 2600 FT OF RWY; WHICH I CHKED AS SUFFICIENT WITH AMBIENT TEMP OF 85 DEG F. IT IS NOT UNCOMMON FOR CIVILIAN ACFT TO TKOF AND LAND ON GRASS OR TXWYS WHEN THERE IS RWY CONSTRUCTION; OR CONSTRUCTION IN THE AREA. TXWY TKOF AND LNDG HAVE BEEN OCCURRING IN BOULDER AND LONGMONT THE LAST 3 YRS. SPECIFICALLY; MY CLRED FOR TKOF INSTRUCTIONS DID NOT INCLUDE XING A TXWY AND AT AN IDENTIFIED INTXN WITH NUMBER OR LETTER (AT ECHO; ETC); OR WITH SOME OTHER GND POS IDENT; WHICH COULD EASILY HAVE BEEN ABSENT DUE TO CONSTRUCTION. I AM NOT AWARE OF ANY FAA REG THAT REQUIRES A PLT TO KEEP A LOGBOOK. I WAS NOT CARRYING ANY PAX IN LINCOLN; AND ON A VFR FLT. VIA GND CTL INSTRUCTIONS; I; AS PLT; WAS DOING RUN-UP ON AN OFF RAMP AND CLRED FROM THE POINT OF RUN-UP TO TKOF; WITH 2600 FT OF RWY; WHICH DID NOT HELP ME CLARIFY MY GND POS. IN THE CTL CABIN I HAD THE MINIMUM (TEXTURAL) NOAA ARPT DIAGRAM. THERE WERE NO RWY SIGN LOCATION IDENT MARKERS. I WOULD BE GLAD TO BE HELPFUL WITH YOUR INVESTIGATION AND MEET WITH AN FAA INSPECTOR IN OUR AREA. IF REMEDIAL ACTION IS DEEMED NECESSARY; AFTER FULL INVESTIGATION OF CULPABILITY; ADDITIONAL EDUCATION SHOULD BE NO PROB. I WILL NEED PARTICULARS.
