Narrative:

It was my first officer's leg flying and we landed on runway 28R in sfo. She steered towards the highspd taxiway and I was just getting ready to take the flight controls, as the tower told us to hold short of runway 28L. I acknowledged the hold short transmission and took control over the aircraft. Slowing down, I thought we were cleared to cross and asked my first officer to confirm that. She said, 'yes' we are cleared to cross. Looking back, I saw air carrier Y also crossing further down on runway 28L. As we crossed runway 28L, an airplane went around. I was told to call the tower supervisor. I did so and explained to him what happened. Supplemental information from acn #564881: the captain apparently had forgotten her readback to the tower. When I looked up, we were crossing the runway, I then quickly tuned in ground control and called them. They asked us to taxi in and contact them after parking. I believe if the xfer of controls been accomplished earlier, there would have been less confusion in the cockpit.

Title: E-120 CREW HAD A RWY INCURSION ON RWY 28L AT SFO AFTER THE CAPT DID NOT REMEMBER WHETHER SHE HAD BEEN CLRED TO CROSS OR NOT.

Narrative: IT WAS MY FO'S LEG FLYING AND WE LANDED ON RWY 28R IN SFO. SHE STEERED TOWARDS THE HIGHSPD TXWY AND I WAS JUST GETTING READY TO TAKE THE FLT CTLS, AS THE TWR TOLD US TO HOLD SHORT OF RWY 28L. I ACKNOWLEDGED THE HOLD SHORT XMISSION AND TOOK CTL OVER THE ACFT. SLOWING DOWN, I THOUGHT WE WERE CLRED TO CROSS AND ASKED MY FO TO CONFIRM THAT. SHE SAID, 'YES' WE ARE CLRED TO CROSS. LOOKING BACK, I SAW ACR Y ALSO XING FURTHER DOWN ON RWY 28L. AS WE CROSSED RWY 28L, AN AIRPLANE WENT AROUND. I WAS TOLD TO CALL THE TWR SUPVR. I DID SO AND EXPLAINED TO HIM WHAT HAPPENED. SUPPLEMENTAL INFO FROM ACN #564881: THE CAPT APPARENTLY HAD FORGOTTEN HER READBACK TO THE TWR. WHEN I LOOKED UP, WE WERE XING THE RWY, I THEN QUICKLY TUNED IN GND CTL AND CALLED THEM. THEY ASKED US TO TAXI IN AND CONTACT THEM AFTER PARKING. I BELIEVE IF THE XFER OF CTLS BEEN ACCOMPLISHED EARLIER, THERE WOULD HAVE BEEN LESS CONFUSION IN THE COCKPIT.
