Narrative:

In 5/91, we experienced a near miss between 300 and 200' AGL while in the process of landing at sfo. We were air carrier X flight from pit, an medium large transport X, and the other aircraft was air carrier Y flight from lax, also an medium large transport Y. We were cleared for the quiet bridge approach. We clearly had the airport in sight. We were assigned a speed of 170 KTS, which was reduced to 160 KTS just prior to bridge. Approach pointed out our traffic to follow was a heavy, and our landing 'partner' an medium large transport Y for the left. Approach said that our speed was to pair us up with parallel traffic. I offset slightly to the east of the localizer to avoid the heavy transport wake turbulence, and also to give us plenty of clearance with the parallel traffic. We were abeam the other inside of brijj. The wind was 280/23 at 4000'. At about 300', we were still slightly displaced to the right of the localizer, feeling a little crowded by the medium large transport Y jet, but still in a comfortable place to land. I said to the captain, 'he's going above G/south.' he then made a move to line up with the 28R. I turned more to the right to avoid him. The captain then said on the radio, 'tower, confirm the landing runway for air carrier Y.' the response was, 'for 28L.' at about 200' the air carrier Y aircraft added power, pulled up, and banked sharply to the left. He managed to land west/O incident on the left. We were able to maintain G/south the whole time, but we were displaced to the right of the localizer. The contributing factors were: 1) the air carrier Y pilots somehow missed their clearance to the left runway way back at menlo. 2) since the pilots were based in chicago, perhaps they weren't used to the normal occurrence of parallel traffic on the tipp toe/quiet bridge approachs. The localizer for 28L (108.5) was notamed out, so he may have talked himself into a 28R landing by tuning in 111.7--initially just for G/south, but then tracking the localizer.

Title: CLOSE PROX 2 ACR MG ACFT ON VISUAL BRIGG APCH TO SFO AT NIGHT.

Narrative: IN 5/91, WE EXPERIENCED A NEAR MISS BTWN 300 AND 200' AGL WHILE IN THE PROCESS OF LNDG AT SFO. WE WERE ACR X FLT FROM PIT, AN MLG X, AND THE OTHER ACFT WAS ACR Y FLT FROM LAX, ALSO AN MLG Y. WE WERE CLRED FOR THE QUIET BRIDGE APCH. WE CLEARLY HAD THE ARPT IN SIGHT. WE WERE ASSIGNED A SPD OF 170 KTS, WHICH WAS REDUCED TO 160 KTS JUST PRIOR TO BRIDGE. APCH POINTED OUT OUR TFC TO FOLLOW WAS A HEAVY, AND OUR LNDG 'PARTNER' AN MLG Y FOR THE LEFT. APCH SAID THAT OUR SPD WAS TO PAIR US UP WITH PARALLEL TFC. I OFFSET SLIGHTLY TO THE E OF THE LOC TO AVOID THE HVT WAKE TURB, AND ALSO TO GIVE US PLENTY OF CLRNC WITH THE PARALLEL TFC. WE WERE ABEAM THE OTHER INSIDE OF BRIJJ. THE WIND WAS 280/23 AT 4000'. AT ABOUT 300', WE WERE STILL SLIGHTLY DISPLACED TO THE RIGHT OF THE LOC, FEELING A LITTLE CROWDED BY THE MLG Y JET, BUT STILL IN A COMFORTABLE PLACE TO LAND. I SAID TO THE CAPT, 'HE'S GOING ABOVE G/S.' HE THEN MADE A MOVE TO LINE UP WITH THE 28R. I TURNED MORE TO THE RIGHT TO AVOID HIM. THE CAPT THEN SAID ON THE RADIO, 'TWR, CONFIRM THE LNDG RWY FOR ACR Y.' THE RESPONSE WAS, 'FOR 28L.' AT ABOUT 200' THE ACR Y ACFT ADDED PWR, PULLED UP, AND BANKED SHARPLY TO THE LEFT. HE MANAGED TO LAND W/O INCIDENT ON THE LEFT. WE WERE ABLE TO MAINTAIN G/S THE WHOLE TIME, BUT WE WERE DISPLACED TO THE RIGHT OF THE LOC. THE CONTRIBUTING FACTORS WERE: 1) THE ACR Y PLTS SOMEHOW MISSED THEIR CLRNC TO THE LEFT RWY WAY BACK AT MENLO. 2) SINCE THE PLTS WERE BASED IN CHICAGO, PERHAPS THEY WEREN'T USED TO THE NORMAL OCCURRENCE OF PARALLEL TFC ON THE TIPP TOE/QUIET BRIDGE APCHS. THE LOC FOR 28L (108.5) WAS NOTAMED OUT, SO HE MAY HAVE TALKED HIMSELF INTO A 28R LNDG BY TUNING IN 111.7--INITIALLY JUST FOR G/S, BUT THEN TRACKING THE LOC.
