A B58 COMMERCIAL ATX PLT CROSSES RWY 32R; THE ACTIVE RWY; FOR A DEP ON RWY 32L; THE CLOSED RWY; AT OMA; NE.

Narrative

WHILE PARKED AT THE FBO; I STARTED THE ENGS AND LISTENED TO ATIS; THEN CALLED FOR MY IFR CLRNC. I WAS CLRED TO TAXI TO RWY 32R. I DIDN'T WRITE DOWN WHICH RWY THAT I WAS CLRED TO TAXI TO; AND I THOUGHT RWY 32R WAS CLOSED. IN FACT; RWY 32L WAS THE CLOSED RWY; AS RPTED IN THE ATIS BROADCAST; WHICH I ALSO NEGLECTED TO WRITE DOWN. THEREFORE; I PROCEEDED TO TAXI TO RWY 32L; THINKING THAT WAS THE OPEN RWY. IN ORDER TO GET TO RWY 32L; I HAD TO CROSS RWY 32R; WHICH I THOUGHT I WAS CLRED TO DO. AFTER XING RWY 32R; THE CTLR INFORMED ME OF MY MISTAKE; AND CLRED ME FOR A 180 DEG TURN BACK TO RWY 32R. I THINK THE MAIN FACTORS THAT CONTRIBUTED TO THIS INCIDENT WERE: NOT WRITING DOWN THE ATIS BROADCAST WHEN I LISTENED TO IT; NOT CLARIFYING MY TAXI INSTRUCTIONS BEFORE I CROSSED THE ACTIVE RWY -- EVEN THOUGH I DID HAVE A SMALL DOUBT IN MY MIND AS TO WHICH RWY WAS CLOSED; AND THE FACT THAT I WAS TIRED. I WAS WELL WITHIN MY DUTY TIME LIMITS; AND ACTUALLY DUTY TIME WAS NOT A FACTOR IN THIS FLT BECAUSE I HAD JUST DROPPED OFF THE PAX AND WAS EMPTY; THEREFORE; IT WAS A PART 91 LEG. BUT THE FACT REMAINS THAT I WAS TIRED AND FATIGUED. IT WAS XA00 AND I BEGAN MY DAY THE PREVIOUS MORNING AT AG00. EVEN THOUGH I DIDN'T START FLYING OR START MY DUTY DAY UNTIL 6 HRS LATER; I WAS TIRED AND THEREFORE LESS ATTENTIVE TO DETAIL. IN THE FUTURE; I WILL CONSIDER THIS LIMITATION MORE SERIOUSLY.
