Narrative:

We were leaving hou, pushed back for a short taxi to runway 12R, as we started taxiing and doing our checklists, ground asked if we were ready to go. Even though we would be no problem being set to go by the time we got to the runway. Ground cleared us to cross runway 12L and hold short runway 12R. The copilot was finishing the checklists and making sure the flight attendants were settled. I was concentrating on making sure I got to runway 12R and not runway 17, and got into the mind-set we were going to be cleared for takeoff right away. As we approached the hold short line, I assumed we had been cleared into position and hold. At the hold short line I asked the copilot to check for landing traffic and confirm with tower we were position and hold. He was just getting off the interphone with the flight attendants, and had to wait for a tower transmission, but when he asked tower to confirm position and hold, tower told us we were only cleared to hold short. Unfortunately, in anticipation I had started rolling, and had crept across the hold short line. We informed tower, and he instructed an aircraft to go around. After which we were cleared for takeoff. 2 things that greatly contributed to this event were hurrying and fatigue. Although short taxies are a part of the business, with the fatigue we both felt, we should have been more aware of our limitations, and that fatigue lessens our capabilities. In this case going slower, doublechking our information, not making assumptions, and making sure both pilots are in the loop to xchk each other would have been more prudent. Supplemental information from acn 529712: we were taxiing from the terminal ramp at hou to runway 12R -- a very short and busy taxi that crosses 2 runways. At the hold line for runway 12L, we were instructed to contact tower. Tower was contacted and we were instructed to cross runway 12L and runway 17 and hold short of runway 12R. We taxied to runway 12R and crossed over the hold line by about 4 ft. I notified tower immediately that we had crossed the hold line. There was an air carrier DC9 on a 2 mi final to runway 12R and they were instructed to go around. Contributing factors: short taxi with engine start, taxi and takeoff checklists to be completed in short time. Flight attendant, informing crew through interphone that cabin was ready for takeoff. This was done at a very busy time for the cockpit crew. Factors affecting the quality of human performance: the captain and I were very tired. Our trip was legal to fly, however, the hours were very hard to get used to with sleep patterns. The first day we got to our hotel at XA00. The final day had us getting up at XC15. By the 4TH and final day of this trip we were both extremely tired from these irregular hours. Lack of adequate sleep definitely had a large role in this occurrence.

Title: AN ACR CREW MAKES THE CASE THAT FATIGUE GENERATED BY SCHEDULING OF A MULTI-DAY TRIP IS A BIG CONTRIBUTOR TO A RWY INCURSION THAT RESULTED IN A GAR BY ANOTHER ACR.

Narrative: WE WERE LEAVING HOU, PUSHED BACK FOR A SHORT TAXI TO RWY 12R, AS WE STARTED TAXIING AND DOING OUR CHKLISTS, GND ASKED IF WE WERE READY TO GO. EVEN THOUGH WE WOULD BE NO PROB BEING SET TO GO BY THE TIME WE GOT TO THE RWY. GND CLRED US TO CROSS RWY 12L AND HOLD SHORT RWY 12R. THE COPLT WAS FINISHING THE CHKLISTS AND MAKING SURE THE FLT ATTENDANTS WERE SETTLED. I WAS CONCENTRATING ON MAKING SURE I GOT TO RWY 12R AND NOT RWY 17, AND GOT INTO THE MIND-SET WE WERE GOING TO BE CLRED FOR TKOF RIGHT AWAY. AS WE APCHED THE HOLD SHORT LINE, I ASSUMED WE HAD BEEN CLRED INTO POS AND HOLD. AT THE HOLD SHORT LINE I ASKED THE COPLT TO CHK FOR LNDG TFC AND CONFIRM WITH TWR WE WERE POS AND HOLD. HE WAS JUST GETTING OFF THE INTERPHONE WITH THE FLT ATTENDANTS, AND HAD TO WAIT FOR A TWR XMISSION, BUT WHEN HE ASKED TWR TO CONFIRM POS AND HOLD, TWR TOLD US WE WERE ONLY CLRED TO HOLD SHORT. UNFORTUNATELY, IN ANTICIPATION I HAD STARTED ROLLING, AND HAD CREPT ACROSS THE HOLD SHORT LINE. WE INFORMED TWR, AND HE INSTRUCTED AN ACFT TO GO AROUND. AFTER WHICH WE WERE CLRED FOR TKOF. 2 THINGS THAT GREATLY CONTRIBUTED TO THIS EVENT WERE HURRYING AND FATIGUE. ALTHOUGH SHORT TAXIES ARE A PART OF THE BUSINESS, WITH THE FATIGUE WE BOTH FELT, WE SHOULD HAVE BEEN MORE AWARE OF OUR LIMITATIONS, AND THAT FATIGUE LESSENS OUR CAPABILITIES. IN THIS CASE GOING SLOWER, DOUBLECHKING OUR INFO, NOT MAKING ASSUMPTIONS, AND MAKING SURE BOTH PLTS ARE IN THE LOOP TO XCHK EACH OTHER WOULD HAVE BEEN MORE PRUDENT. SUPPLEMENTAL INFO FROM ACN 529712: WE WERE TAXIING FROM THE TERMINAL RAMP AT HOU TO RWY 12R -- A VERY SHORT AND BUSY TAXI THAT CROSSES 2 RWYS. AT THE HOLD LINE FOR RWY 12L, WE WERE INSTRUCTED TO CONTACT TWR. TWR WAS CONTACTED AND WE WERE INSTRUCTED TO CROSS RWY 12L AND RWY 17 AND HOLD SHORT OF RWY 12R. WE TAXIED TO RWY 12R AND CROSSED OVER THE HOLD LINE BY ABOUT 4 FT. I NOTIFIED TWR IMMEDIATELY THAT WE HAD CROSSED THE HOLD LINE. THERE WAS AN ACR DC9 ON A 2 MI FINAL TO RWY 12R AND THEY WERE INSTRUCTED TO GO AROUND. CONTRIBUTING FACTORS: SHORT TAXI WITH ENG START, TAXI AND TKOF CHKLISTS TO BE COMPLETED IN SHORT TIME. FLT ATTENDANT, INFORMING CREW THROUGH INTERPHONE THAT CABIN WAS READY FOR TKOF. THIS WAS DONE AT A VERY BUSY TIME FOR THE COCKPIT CREW. FACTORS AFFECTING THE QUALITY OF HUMAN PERFORMANCE: THE CAPT AND I WERE VERY TIRED. OUR TRIP WAS LEGAL TO FLY, HOWEVER, THE HRS WERE VERY HARD TO GET USED TO WITH SLEEP PATTERNS. THE FIRST DAY WE GOT TO OUR HOTEL AT XA00. THE FINAL DAY HAD US GETTING UP AT XC15. BY THE 4TH AND FINAL DAY OF THIS TRIP WE WERE BOTH EXTREMELY TIRED FROM THESE IRREGULAR HRS. LACK OF ADEQUATE SLEEP DEFINITELY HAD A LARGE ROLE IN THIS OCCURRENCE.
