Narrative:

After receiving clearance and taxi instructions (taxiway K/B to taxiway B3 for runway 27R departure) I inadvertently turned right onto the overrun for runway 27C. After making the turn, I noticed the chevrons and immediately called ground control to clarify and ask for further instructions. I was told to make a 180 degree turn. I followed the instructions, got on the proper txwys. On the continued taxi, I was asked to call the tower when reaching destination. I called from the airplane while still on the ground. The person in charge returned my call later to tell me that what happened would be recorded only as to what happened. There was never a separation issue (as to other traffic) and I did not actually taxi onto an active runway, only the displaced threshold. We also discussed how poorly marked the displaced threshold is. There has been and is ongoing construction in this area of sfb. Many taxi areas are poorly painted or not painted at all. I believe this needs to be addressed with sfb airport authority/authorized.

Title: BE40 RPTR RWY INCURSION SFB. RPTR CITES CONSTRUCTION ZONES WITH POORLY MARKED, POORLY SIGNED TAXI ROUTING AND OR INSTRUCTIONS.

Narrative: AFTER RECEIVING CLRNC AND TAXI INSTRUCTIONS (TXWY K/B TO TXWY B3 FOR RWY 27R DEP) I INADVERTENTLY TURNED R ONTO THE OVERRUN FOR RWY 27C. AFTER MAKING THE TURN, I NOTICED THE CHEVRONS AND IMMEDIATELY CALLED GND CTL TO CLARIFY AND ASK FOR FURTHER INSTRUCTIONS. I WAS TOLD TO MAKE A 180 DEG TURN. I FOLLOWED THE INSTRUCTIONS, GOT ON THE PROPER TXWYS. ON THE CONTINUED TAXI, I WAS ASKED TO CALL THE TWR WHEN REACHING DEST. I CALLED FROM THE AIRPLANE WHILE STILL ON THE GND. THE PERSON IN CHARGE RETURNED MY CALL LATER TO TELL ME THAT WHAT HAPPENED WOULD BE RECORDED ONLY AS TO WHAT HAPPENED. THERE WAS NEVER A SEPARATION ISSUE (AS TO OTHER TFC) AND I DID NOT ACTUALLY TAXI ONTO AN ACTIVE RWY, ONLY THE DISPLACED THRESHOLD. WE ALSO DISCUSSED HOW POORLY MARKED THE DISPLACED THRESHOLD IS. THERE HAS BEEN AND IS ONGOING CONSTRUCTION IN THIS AREA OF SFB. MANY TAXI AREAS ARE POORLY PAINTED OR NOT PAINTED AT ALL. I BELIEVE THIS NEEDS TO BE ADDRESSED WITH SFB ARPT AUTH.
