AN ACR ACFT GOES AROUND WHEN RWY 27 AT BOS IS NOT CLRED FOR LNDG. A B757 WAS HOLDING SHORT OF RWY 4R ON RWY 27.

Narrative

DURING VISUAL APCH TO RWY 27; TWR (119.1) CLRED OUR FLT TO LAND. ACFT WAS SLOWED TO ALLOW FOR EXIT AT TXWY E. I XFERRED CTL TO CAPT. HE ROLLED PAST TXWY E AND STOPPED SHORT OF RWY 4R/22L. THE CAPT APPEARED TO STEER ONTO RWY 4R. I TOLD HIM A RWY SHOULDN'T BE USED AS TXWY UNLESS ATC CLRED US FOR A TURN ONTO THAT RWY. HE STOPPED SHORT OF RWY 4R/22L AND I INQUIRED OF TWR WHETHER RWY 4R/22L WAS AVAILABLE. A SECOND INQUIRY BROUGHT THE FIRST COM FROM TWR I HAD HEARD SINCE BEING IN THE AIR. WE WERE CLRED TO EXIT AT TXWY W; HOLD SHORT OF RWY 4L; CONTACT TWR ON 128.8. ONCE CLRED ACROSS RWY 4L AND SWITCHED TO GND ON 121.9 WE WERE ASKED TO PHONE THE TWR. THE CAPT SPOKE TO THE TWR TWICE AND TOLD ME THE ACFT BEHIND US WENT AROUND WHICH CAUSED SOME CONFUSION. MY CAPT SAID THE MATTER WAS RESOLVED AND NO FURTHER ACTION WAS REQUIRED. I NEVER SPOKE WITH THE TWR ABOUT THIS. ATIS LAND AND HOLD SHORT INFO MAY HAVE CONTRIBUTED TO THIS SIT BECAUSE IT WAS CLR THE CAPT DIDN'T WANT TO TAXI ACROSS RWY 4R/22L WHILE WE WERE ON RWY 27 AND WE HAD NOT HEARD ANY INSTRUCTIONS REGARDING CLRING THE RWY UNTIL MY SECOND INQUIRY.
