Narrative:

Aircraft was originally cleared to land on runway 18R. Due to disabled aircraft on runway, landing clearance was reissued, and we were cleared to sidestep to runway 18L and cleared to land. After landing tower cleared us to taxi to our ramp. We asked tower if we could turn right onto runway 9/27, then use taxiway C, and taxiway J to taxiway. Captain turned right on taxiway C, then turned left on taxiway north. Captain thought he was on taxiway J. Aircraft came to a stop at the end of taxiway north. That's when captain realized he was on wrong taxiway. Tower then cleared us to turn left onto runway 9/27, taxi back to taxiway C, go to taxiway B, turn left, then take taxiway west. Upon entering runway 9/27, captain began a faster than normal taxi speed. I (first officer) told captain not to miss taxiway C, that it was coming up and prior to runway 18L. After I looked up from taxiway airport diagram, captain had already passed taxiway C, and was crossing runway 18L. Captain was obviously disoriented as to his position and that of taxiway C. Aircraft crossed runway 18L without clearance, tower then gave a progressive to the ramp. Captain should not have taxied as fast as he was, and when he realized that he was disoriented with relation to his position on ground, he should have stopped aircraft immediately. Also, he could have used his crew member's instructions, but elected to disregard them. In any event a runway incursion did take place upon runway 18L from the intersection of runway 9/27 at tpa airport. No loss of separation ever occurred.

Title: CREW TAXIING LGT CARGOLINER GOT CONFUSED AND CROSSED ACTIVE RWY 18L WITHOUT CLRNC. RWY INCURSION.

Narrative: ACFT WAS ORIGINALLY CLRED TO LAND ON RWY 18R. DUE TO DISABLED ACFT ON RWY, LNDG CLRNC WAS REISSUED, AND WE WERE CLRED TO SIDESTEP TO RWY 18L AND CLRED TO LAND. AFTER LNDG TWR CLRED US TO TAXI TO OUR RAMP. WE ASKED TWR IF WE COULD TURN R ONTO RWY 9/27, THEN USE TXWY C, AND TXWY J TO TXWY. CAPT TURNED R ON TXWY C, THEN TURNED L ON TXWY N. CAPT THOUGHT HE WAS ON TXWY J. ACFT CAME TO A STOP AT THE END OF TXWY N. THAT'S WHEN CAPT REALIZED HE WAS ON WRONG TXWY. TWR THEN CLRED US TO TURN L ONTO RWY 9/27, TAXI BACK TO TXWY C, GO TO TXWY B, TURN L, THEN TAKE TXWY W. UPON ENTERING RWY 9/27, CAPT BEGAN A FASTER THAN NORMAL TAXI SPD. I (FO) TOLD CAPT NOT TO MISS TXWY C, THAT IT WAS COMING UP AND PRIOR TO RWY 18L. AFTER I LOOKED UP FROM TXWY ARPT DIAGRAM, CAPT HAD ALREADY PASSED TXWY C, AND WAS XING RWY 18L. CAPT WAS OBVIOUSLY DISORIENTED AS TO HIS POS AND THAT OF TXWY C. ACFT CROSSED RWY 18L WITHOUT CLRNC, TWR THEN GAVE A PROGRESSIVE TO THE RAMP. CAPT SHOULD NOT HAVE TAXIED AS FAST AS HE WAS, AND WHEN HE REALIZED THAT HE WAS DISORIENTED WITH RELATION TO HIS POS ON GND, HE SHOULD HAVE STOPPED ACFT IMMEDIATELY. ALSO, HE COULD HAVE USED HIS CREW MEMBER'S INSTRUCTIONS, BUT ELECTED TO DISREGARD THEM. IN ANY EVENT A RWY INCURSION DID TAKE PLACE UPON RWY 18L FROM THE INTXN OF RWY 9/27 AT TPA ARPT. NO LOSS OF SEPARATION EVER OCCURRED.
