Narrative:

Aircraft was cleared to taxi from east ramp to runway 23L. Aircraft was instructed to 'taxi to runway 23L via east ramp and runway 27R; hold short 23L.' copilot taxied north on east ramp; E1; onto runway 27R and past hold short lines on runway 27R. Copilot was instructed by PIC to stop. Copilot did not see hold short lines on runway 27R. I think the biggest contributing factor was the unusual placement of the hold short lines on runway 27R. I never saw hold short lines on a runway before and apparently didn't see these. Unfortunately the captain was heads down running a checklist at the worst possible time. We won't make this mistake again. A learjet on final was asked to sidestep to runway 23R. As far as I know there was not a traffic conflict between our 2 planes. Supplemental information from acn 800933: the contributing factors were me not having my head outside while we were in motion. The PF thought it was a bit confusing as to where he had to hold short for runway 23L. From now on I will have my head outside anytime we are in motion while on the ground. I'm not sure how the runway to runway hold short markings could be improved; but it is a bit different from taxiway to runway markings. Since the majority of taxiing to runways is done on a taxiway I can see how it can be a bit confusing when taxiing to a runway from a runway.

Title: A CL605 FLT CREW TAXIED ACROSS THE HOLD SHORT LINE FOR 23L AT YIP IN PART BECAUSE IT IS LOCATED ON RWY 27R.

Narrative: ACFT WAS CLRED TO TAXI FROM E RAMP TO RWY 23L. ACFT WAS INSTRUCTED TO 'TAXI TO RWY 23L VIA E RAMP AND RWY 27R; HOLD SHORT 23L.' COPLT TAXIED N ON E RAMP; E1; ONTO RWY 27R AND PAST HOLD SHORT LINES ON RWY 27R. COPLT WAS INSTRUCTED BY PIC TO STOP. COPLT DID NOT SEE HOLD SHORT LINES ON RWY 27R. I THINK THE BIGGEST CONTRIBUTING FACTOR WAS THE UNUSUAL PLACEMENT OF THE HOLD SHORT LINES ON RWY 27R. I NEVER SAW HOLD SHORT LINES ON A RWY BEFORE AND APPARENTLY DIDN'T SEE THESE. UNFORTUNATELY THE CAPT WAS HEADS DOWN RUNNING A CHKLIST AT THE WORST POSSIBLE TIME. WE WON'T MAKE THIS MISTAKE AGAIN. A LEARJET ON FINAL WAS ASKED TO SIDESTEP TO RWY 23R. AS FAR AS I KNOW THERE WAS NOT A TFC CONFLICT BTWN OUR 2 PLANES. SUPPLEMENTAL INFO FROM ACN 800933: THE CONTRIBUTING FACTORS WERE ME NOT HAVING MY HEAD OUTSIDE WHILE WE WERE IN MOTION. THE PF THOUGHT IT WAS A BIT CONFUSING AS TO WHERE HE HAD TO HOLD SHORT FOR RWY 23L. FROM NOW ON I WILL HAVE MY HEAD OUTSIDE ANYTIME WE ARE IN MOTION WHILE ON THE GND. I'M NOT SURE HOW THE RWY TO RWY HOLD SHORT MARKINGS COULD BE IMPROVED; BUT IT IS A BIT DIFFERENT FROM TXWY TO RWY MARKINGS. SINCE THE MAJORITY OF TAXIING TO RWYS IS DONE ON A TXWY I CAN SEE HOW IT CAN BE A BIT CONFUSING WHEN TAXIING TO A RWY FROM A RWY.
