Narrative:

While taxiing out to the runway for the last leg (a 10 min reposition flight) of a near maximum duty day, the controller issued instructions to 'taxi to runway 9L.' I asked if he had any preference for the route and he did not respond. I went about normal PNF duties of completing checklists, etc, while the other pilot taxied the aircraft. The route to the runway end requires the aircraft to cross the active runway (9L) once before turning west to continue to the end. While looking down at the checklist items, I failed to notice the PF crossing the hold short line of runway 9L at the midpoint of the runway in time to stop the aircraft. The controller immediately brought this to our attention. Fortunately, no conflict occurred as traffic was virtually non existent at AB00 am. Factors were the long duty day which extended into the wee hours of the morning and the nature of the trip, which was an unplanned emergency departure that started with a page that was unexpected. Furthermore, I relied too heavily on the PF probably because he is also a captain, equally experienced, and a strong pilot. Talking to him afterward, he was unclr as to why he was wrong since the controller had not issued a 'hold short' instruction. In relating my experience to other pilots, I've been surprised to hear about 50% of them would have done the same thing. However, all admit that they probably would not have done so during a busy traffic period. In conclusion, I think the fact that pilots are permitted to cross all runways except the active in a taxi clearance is well understood. However, in a situation where the pilots are tired and no traffic exists, we sometimes get complacent and fail to xchk each other. I certainly did and regret it terribly. As a new captain, I'm frustrated that I allowed it to happen but will not forget it and thus, hopefully will avoid such occurrences in the future.

Title: CHARTER JET CREW TAXIES OVER THE HOLD LINE OF THE ACTIVE RWY 9L AT PBI AND MAKES A RWY INCURSION A FACT. THE CREW HAD BEEN CLRED TO TAXI TO RWY 9L AND HAD TO CROSS THAT RWY TO GET TO THE TKOF END AFTER A W TAXI.

Narrative: WHILE TAXIING OUT TO THE RWY FOR THE LAST LEG (A 10 MIN REPOSITION FLT) OF A NEAR MAX DUTY DAY, THE CTLR ISSUED INSTRUCTIONS TO 'TAXI TO RWY 9L.' I ASKED IF HE HAD ANY PREFERENCE FOR THE RTE AND HE DID NOT RESPOND. I WENT ABOUT NORMAL PNF DUTIES OF COMPLETING CHKLISTS, ETC, WHILE THE OTHER PLT TAXIED THE ACFT. THE RTE TO THE RWY END REQUIRES THE ACFT TO CROSS THE ACTIVE RWY (9L) ONCE BEFORE TURNING W TO CONTINUE TO THE END. WHILE LOOKING DOWN AT THE CHKLIST ITEMS, I FAILED TO NOTICE THE PF XING THE HOLD SHORT LINE OF RWY 9L AT THE MIDPOINT OF THE RWY IN TIME TO STOP THE ACFT. THE CTLR IMMEDIATELY BROUGHT THIS TO OUR ATTN. FORTUNATELY, NO CONFLICT OCCURRED AS TFC WAS VIRTUALLY NON EXISTENT AT AB00 AM. FACTORS WERE THE LONG DUTY DAY WHICH EXTENDED INTO THE WEE HRS OF THE MORNING AND THE NATURE OF THE TRIP, WHICH WAS AN UNPLANNED EMER DEP THAT STARTED WITH A PAGE THAT WAS UNEXPECTED. FURTHERMORE, I RELIED TOO HEAVILY ON THE PF PROBABLY BECAUSE HE IS ALSO A CAPT, EQUALLY EXPERIENCED, AND A STRONG PLT. TALKING TO HIM AFTERWARD, HE WAS UNCLR AS TO WHY HE WAS WRONG SINCE THE CTLR HAD NOT ISSUED A 'HOLD SHORT' INSTRUCTION. IN RELATING MY EXPERIENCE TO OTHER PLTS, I'VE BEEN SURPRISED TO HEAR ABOUT 50% OF THEM WOULD HAVE DONE THE SAME THING. HOWEVER, ALL ADMIT THAT THEY PROBABLY WOULD NOT HAVE DONE SO DURING A BUSY TFC PERIOD. IN CONCLUSION, I THINK THE FACT THAT PLTS ARE PERMITTED TO CROSS ALL RWYS EXCEPT THE ACTIVE IN A TAXI CLRNC IS WELL UNDERSTOOD. HOWEVER, IN A SIT WHERE THE PLTS ARE TIRED AND NO TFC EXISTS, WE SOMETIMES GET COMPLACENT AND FAIL TO XCHK EACH OTHER. I CERTAINLY DID AND REGRET IT TERRIBLY. AS A NEW CAPT, I'M FRUSTRATED THAT I ALLOWED IT TO HAPPEN BUT WILL NOT FORGET IT AND THUS, HOPEFULLY WILL AVOID SUCH OCCURRENCES IN THE FUTURE.
