UNAUTHORIZED RWY ENTRY XING OP.

Narrative

WHILE TAXIING OUT TO RWY 1; I ASKED FO TO START #1 ENG PER COMPANY PROC. DURING THE START SEQUENCE THE STEERING PERFORMANCE WAS DECAYING AND I INADVERTENTLY REACHED DOWN FOR THE HYD PUMP OVERRIDE. I WAS STEERING 'MOSTLY STRAIGHT' AND REALIZED THE PUMP WAS NOT AVAILABLE. BUT IN THAT MOMENT OR 2 I HAD PASSED THE HOLD LINE AND WAS ON THE RWY. I GLANCED L ON FINAL AND FINISHED XING THE RWY FIGURING THAT OFF THE RWY WAS BETTER THAN ON. PER COMPANY PROC; THE FO WAS 'INSIDE' DURING THE START. THE INCURSION WAS COMPLETELY MY RESPONSIBILITY. HUMAN PERFORMANCE CONSIDERATIONS: MY SLEEP WAS INTERRUPTED BY TELEPHONE LATE NIGHT PRIOR. RPT WAS EARLY HR. FURTHER; DURING PAST 8 MONTHS I HAD 8 HRS SLEEP EVERY NIGHT AND PAST 2 WKS SINCE RETURN TO DUTY I WAS AVERAGING 5-6 HRS PER NIGHT. THIS SERIES OF FLTS HAD MECHANICAL INTERRUPTIONS EACH LEG; PUTTING US XA15 LATE AT TIME OF INCURSION. HAVING FLOWN THIS PLANE SINCE 1985; WITH THE CAVEAT OF NO PWR DISRUPTION ALLOWED TO AHRS/EFIS. THE NEW COMPANY PROC OF STARTING ENG DURING TAXI IS STILL DISTRACTING TO ME WHEN THE TUBES BLANK AND FLASH DURING SAID START. I MUST EMPHASIZE THAT THE FO PERFORMED EXACTLY TO COMPANY PROC AT ALL TIMES AND I STRAYED ACROSS THE HOLD LINE ON MY OWN. I MUST ADD; HOWEVER; I MISS HIS EYES AND AID DURING THESE STARTS.
