PA30 TAXIING FOR DEP AT TNN CROSSED RWY WITHOUT ATC CLRNC.

Narrative

I WAS PREPARING FOR A SHORT LCL FLT AT MY HOME ARPT; TTN. I HAD COMPLETED THE PREFLT AND WAS DOING SOME CLEAN UP CHORES IN THE AIRPLANE WHEN ANOTHER PLT CAME OVER TO LOOK AT MY AIRPLANE AND SAY HELLO. AFTER A SHORT CONVERSATION; I FINISHED MY CHORES; STARTED THE ENGS AND CALLED FOR TAXI CLRNC. AS I STARTED TO MOVE; A SLIGHT LURCH NOTIFIED ME THAT I HAD NOT UNTIED THE R WING. I SHUT DOWN; UNTIED IT AND PROCEEDED TO TAXI; I WAS MOST ANNOYED WITH MYSELF; AS ALTHOUGH THIS IS NOT A MAJOR ERROR; IN 40 YRS OF FLYING I HAD NOT MADE THIS MISTAKE BEFORE. I DON'T LIKE MAKING MISTAKES. I WAS CLRED TO RWY 6. I KNOW THE ARPT VERY WELL. RWYS 24 AND 34 ARE THE MORE FREQUENT DEP RWY AND ARE CLOSER TO MY TIE DOWN SPOT. I HEARD RWY 6; ACKNOWLEDGED RWY 6; AND WAS THINKING RWY 6; BUT MY FEET TOOK ME TOWARDS RWY 34. IN THE PROCESS; I CROSSED THE DEP END OF RWY 6. AS I DID; I SAW AN ACFT AT THE APCH END OF RWY 6 AND IMMEDIATELY MY MIND; WHICH WAS STILL THINKING ABOUT THE UNTIED R WING; REALIZED MY ERROR. THE TWR DID NOT NOTICE MY ERROR. I CALLED GND CTL AND TOLD THEM OF THE ERROR AND CONTINUED TO TAXI TO THE APCH END OF RWY 6. LESSON #1: FOR ME; ALWAYS CONCENTRATE ON THE TASK AT HAND NO MATTER HOW EASY AND FAMILIAR AND NO MATTER WHAT OTHER DISTRACTIONS ARE COMPETING FOR ATTN. LESSON #2: FOR ME; EVEN AT FAMILIAR CTLED FIELDS; ALWAYS LOOK CAREFULLY BOTH WAYS DOWN INTXNS BEFORE YOU ENTER THEM. I WAS ON THE RWY BEFORE I SAW THE OTHER ACFT AT THE FAR END. LESSON #3: FOR THE TWR; EVEN THE ACFT YOU KNOW AND HANDLE ON A DAILY BASIS CAN MAKE A MISTAKE SO BE VIGILANT.
