Narrative:

There was a very short taxi to the active runway. As a crew of 2, we were busy trying to run checklists and review departure procedures. I taxied the aircraft slowly to allow for time to complete all the required items. Ground gave us clearance to taxi to 'runway 35L via taxiway a.' the distance from runway 35L to our starting point is less than 1500 ft. Needless to say, we were busy. We stopped short of the runway and while holding short, I reviewed the SID. At the same time, ATC (tower now) advised company aircraft to 'cross runway 35C, aircraft is holding in position.' I was not absolutely clear as to if that was our aircraft. The first officer read back the instructions as 'cross runway 35L.' I released the brakes and saw that an MD80 was in position, holding with his lights off. As we began to roll forward, ATC responded 'that was for air carrier XXX.' we were air carrier xxy. I immediately applied heavy braking. The aircraft had already crossed well past the hold line. We were protruding about 1/3 of the way onto the runway. I looked to make sure the MD80 was holding and made a decision to proceed expeditiously across the runway. Looking back, I should have paid more attention to other aircraft and my own with less distrs. I should have just stopped and advised ATC of our situation. Being rushed and anticipating a clearance to cross the runway seemed to make it clear in my mind and my first officer's mind that the call to cross was for us. So I didn't question what he heard.

Title: DURING SHORT TAXI FROM TERMINAL TO RWY, AN SA227 CREW MISTAKE A COMPANY CALL SIGN AS THEIR OWN AND BEGIN TO TAXI ACROSS THE RWY AT DFW.

Narrative: THERE WAS A VERY SHORT TAXI TO THE ACTIVE RWY. AS A CREW OF 2, WE WERE BUSY TRYING TO RUN CHKLISTS AND REVIEW DEP PROCS. I TAXIED THE ACFT SLOWLY TO ALLOW FOR TIME TO COMPLETE ALL THE REQUIRED ITEMS. GND GAVE US CLRNC TO TAXI TO 'RWY 35L VIA TXWY A.' THE DISTANCE FROM RWY 35L TO OUR STARTING POINT IS LESS THAN 1500 FT. NEEDLESS TO SAY, WE WERE BUSY. WE STOPPED SHORT OF THE RWY AND WHILE HOLDING SHORT, I REVIEWED THE SID. AT THE SAME TIME, ATC (TWR NOW) ADVISED COMPANY ACFT TO 'CROSS RWY 35C, ACFT IS HOLDING IN POS.' I WAS NOT ABSOLUTELY CLR AS TO IF THAT WAS OUR ACFT. THE FO READ BACK THE INSTRUCTIONS AS 'CROSS RWY 35L.' I RELEASED THE BRAKES AND SAW THAT AN MD80 WAS IN POS, HOLDING WITH HIS LIGHTS OFF. AS WE BEGAN TO ROLL FORWARD, ATC RESPONDED 'THAT WAS FOR ACR XXX.' WE WERE ACR XXY. I IMMEDIATELY APPLIED HVY BRAKING. THE ACFT HAD ALREADY CROSSED WELL PAST THE HOLD LINE. WE WERE PROTRUDING ABOUT 1/3 OF THE WAY ONTO THE RWY. I LOOKED TO MAKE SURE THE MD80 WAS HOLDING AND MADE A DECISION TO PROCEED EXPEDITIOUSLY ACROSS THE RWY. LOOKING BACK, I SHOULD HAVE PAID MORE ATTN TO OTHER ACFT AND MY OWN WITH LESS DISTRS. I SHOULD HAVE JUST STOPPED AND ADVISED ATC OF OUR SIT. BEING RUSHED AND ANTICIPATING A CLRNC TO CROSS THE RWY SEEMED TO MAKE IT CLR IN MY MIND AND MY FO'S MIND THAT THE CALL TO CROSS WAS FOR US. SO I DIDN'T QUESTION WHAT HE HEARD.
