Narrative:

We were cleared to taxi to runway 36. We entered taxiway D at D1 which is the parallel taxiway to the approach end of runway 6. There was a lot of radio chatter with rertes for a commuter holding for takeoff at runway 6. As we were taxiing, the commuter went over to tower and was taxiing into position on runway 6. The ground controller told us to hold short of runway 6. We should have held short of runway 6 at taxiway M. But what we did was cross runway 36 and proceed to and hold short of runway 6 where the tower told us that we had proceeded to the wrong runway. What we should have done is taxi [southwest] on taxiway D to join taxiway M. In our original clearance, we were cleared to runway 36, so therefore, we would have crossed runway 6 on taxiway M to proceed to the departure end of runway 36 to hold and contact the tower for a takeoff clearance. The PF said that he thought we were cleared to taxi to runway 6 for departure. The PNF for whatever reason mistook the clearance to hold short of runway 6 for departure on runway 6. Probably because the commuter was departing on runway 6. There was no conflict with the departing aircraft. Looking back what happened was a breakdown in CRM. We neglected to both physically look at the airport diagram to discuss the appropriate runway and the txwys to be used to get there. Another thing is that it was an airport that we had been to before and were just slack. In the future, I will take more time to look and discuss the airport diagram. Also, if any confusion, verify with ATC if you both did not understand what was given.

Title: TAXI TO WRONG RWY BY DA20 FLT CREW AT GRB.

Narrative: WE WERE CLRED TO TAXI TO RWY 36. WE ENTERED TXWY D AT D1 WHICH IS THE PARALLEL TXWY TO THE APCH END OF RWY 6. THERE WAS A LOT OF RADIO CHATTER WITH RERTES FOR A COMMUTER HOLDING FOR TKOF AT RWY 6. AS WE WERE TAXIING, THE COMMUTER WENT OVER TO TWR AND WAS TAXIING INTO POS ON RWY 6. THE GND CTLR TOLD US TO HOLD SHORT OF RWY 6. WE SHOULD HAVE HELD SHORT OF RWY 6 AT TXWY M. BUT WHAT WE DID WAS CROSS RWY 36 AND PROCEED TO AND HOLD SHORT OF RWY 6 WHERE THE TWR TOLD US THAT WE HAD PROCEEDED TO THE WRONG RWY. WHAT WE SHOULD HAVE DONE IS TAXI [SW] ON TXWY D TO JOIN TXWY M. IN OUR ORIGINAL CLRNC, WE WERE CLRED TO RWY 36, SO THEREFORE, WE WOULD HAVE CROSSED RWY 6 ON TXWY M TO PROCEED TO THE DEP END OF RWY 36 TO HOLD AND CONTACT THE TWR FOR A TKOF CLRNC. THE PF SAID THAT HE THOUGHT WE WERE CLRED TO TAXI TO RWY 6 FOR DEP. THE PNF FOR WHATEVER REASON MISTOOK THE CLRNC TO HOLD SHORT OF RWY 6 FOR DEP ON RWY 6. PROBABLY BECAUSE THE COMMUTER WAS DEPARTING ON RWY 6. THERE WAS NO CONFLICT WITH THE DEPARTING ACFT. LOOKING BACK WHAT HAPPENED WAS A BREAKDOWN IN CRM. WE NEGLECTED TO BOTH PHYSICALLY LOOK AT THE ARPT DIAGRAM TO DISCUSS THE APPROPRIATE RWY AND THE TXWYS TO BE USED TO GET THERE. ANOTHER THING IS THAT IT WAS AN ARPT THAT WE HAD BEEN TO BEFORE AND WERE JUST SLACK. IN THE FUTURE, I WILL TAKE MORE TIME TO LOOK AND DISCUSS THE ARPT DIAGRAM. ALSO, IF ANY CONFUSION, VERIFY WITH ATC IF YOU BOTH DID NOT UNDERSTAND WHAT WAS GIVEN.
