TWO ACR MLG'S NEARLY COLLIDED ON THE GND WHEN CTLR FAILED TO ADVISE EITHER ACFT OF PERTINENT TRAFFIC.

Narrative

AFTER LNDG RWY 28L SFO INTL ARPT ON MON OF MAY 1988 THE TWR CTLR SAID AND I QUOTE 'MLG X CLRED TO THE GATE VIA L TURN ON THE OUTER R TURN HOTEL; STAY WITH ME.' I COMPLIED WITH THE CLRNC AND IN MY R TURN AT HOTEL TXWY I SAW THE BRIGHTEST NOSE GEAR TAXI LIGHT I EVER SAW THROUGH MY F/O WINDOW. I IMMEDIATELY APPLIED FULL BRAKE PRESSURE STOPPING THE ACFT IMMEDIATELY. AFTER MLG Y WHICH APPARENTLY WAS TO MY R REAR ON THE INNER TXWY WENT VERY CLOSELY BY ME; I REGAINED MY COMPOSURE AND ASKED THE TWR CTLR WHY I WAS NOT ADVISED OF MLG Y. HIS RESPONSE WAS; 'SORRY ABOUT THAT MLG X; MY MISTAKE.' A COUPLE OF OTHER EXCHANGES WERE MADE AND WE TAXIED TO THE GATE. ON ARR AT THE GATE I CALLED THE TWR AND THE CTLR WHO GAVE ME THE TAXI CLRNC ANSWERED THE TELEPHONE AND WHEN I IDENTIFIED MYSELF HE SAID OOPS; LET ME PICK UP AN UNRECORDED PHONE. I TOLD HIM HE DIDN'T HAVE TO ON MY ACCOUNT. HE THEN APOLOGIZED AND SAID HE HAD JUST TAKEN OVER HIS POS AND WAS UNAWARE OF MLG Y ON THE INNER TXWY. I FEEL THIS WAS TOO SERIOUS OF AN INFRACTION TO GO UNREPORTED TO YOU. I DO NOT UNDERSTAND WHY AT AN ARPT LIKE SFO WITH 4 ACTIVE RWYS A TWR OPERATOR WOULD ALSO BE DIRECTING GND TFC.
