Narrative:

Upon clearing runway 29 (south side, air carrier runway) south ground control was contacted. We were cleared to taxi on parallel, left turn (north) on taxiway B, contact north ground (121.9) holding short of B1. Upon contacting north ground, we were cleared to taxi to and hold short of runway 27L. Due to a slight curve, I held about 30 ft short of the hold short point. After a 3-4 min delay, I was cleared to cross runway 27L, hold short of runway 27R. My eventual destination was ramp area by hangar, nearly 1 mi away. Runways 27L and 27R are closely separated parallel runways. Prior to crossing runway 27L, both first officer and I checked the final approach area. A C150 was rolling out on runway 27L, a mooney was on short final to runway 27R and another C150 was noted on left base behind the mooney. As I taxied past the hold line, I saw cessna in a turn to final. About halfway across runway 27L, it was obvious to me that cessna was definitely on a short final and lined up with runway 27L. I expedited taxi as fast as a 230000 pound aircraft could be expedited. Some 30- 40 seconds later, while holding short of runway 27R, I looked behind my left window and saw the C150 climbing out straight ahead on his go around. As we were on ground control and not tower frequency, I don't know if cessna initiated go around on his own accord or was instructed to do so by tower. I believe that this conflict arose either by miscoord between ground and tower, or the cessna may have lined up with the wrong runway, or was cleared to land on the wrong runway. Having flown into lax several times (which also has closely spaced parallel runways) I am aware of the importance of xchking actual traffic with ATC crossing clrncs. This becomes more critical with 'position and hold clrncs,' when your back is turned to landing traffic. In that case, at least I'd be on tower frequency and able to monitor landing traffic clrncs, I suggest that aircraft taxiing north of taxiway B be controled by north tower frequency until across both parallel runways and then be handed over to ground control.

Title: FLC OF A CARGO DC8 WAS CLRED ACROSS PARALLEL RWY IN FRONT OF A C150 ON SHORT FINAL. THE CAPT OF THE DC8 EXPEDITED TAXI ACROSS THE RWY, BUT LATER NOTICED THAT THE C150 HAD MADE A GAR.

Narrative: UPON CLRING RWY 29 (S SIDE, ACR RWY) S GND CTL WAS CONTACTED. WE WERE CLRED TO TAXI ON PARALLEL, L TURN (N) ON TXWY B, CONTACT N GND (121.9) HOLDING SHORT OF B1. UPON CONTACTING N GND, WE WERE CLRED TO TAXI TO AND HOLD SHORT OF RWY 27L. DUE TO A SLIGHT CURVE, I HELD ABOUT 30 FT SHORT OF THE HOLD SHORT POINT. AFTER A 3-4 MIN DELAY, I WAS CLRED TO CROSS RWY 27L, HOLD SHORT OF RWY 27R. MY EVENTUAL DEST WAS RAMP AREA BY HANGAR, NEARLY 1 MI AWAY. RWYS 27L AND 27R ARE CLOSELY SEPARATED PARALLEL RWYS. PRIOR TO XING RWY 27L, BOTH FO AND I CHKED THE FINAL APCH AREA. A C150 WAS ROLLING OUT ON RWY 27L, A MOONEY WAS ON SHORT FINAL TO RWY 27R AND ANOTHER C150 WAS NOTED ON L BASE BEHIND THE MOONEY. AS I TAXIED PAST THE HOLD LINE, I SAW CESSNA IN A TURN TO FINAL. ABOUT HALFWAY ACROSS RWY 27L, IT WAS OBVIOUS TO ME THAT CESSNA WAS DEFINITELY ON A SHORT FINAL AND LINED UP WITH RWY 27L. I EXPEDITED TAXI AS FAST AS A 230000 LB ACFT COULD BE EXPEDITED. SOME 30- 40 SECONDS LATER, WHILE HOLDING SHORT OF RWY 27R, I LOOKED BEHIND MY L WINDOW AND SAW THE C150 CLBING OUT STRAIGHT AHEAD ON HIS GAR. AS WE WERE ON GND CTL AND NOT TWR FREQ, I DON'T KNOW IF CESSNA INITIATED GAR ON HIS OWN ACCORD OR WAS INSTRUCTED TO DO SO BY TWR. I BELIEVE THAT THIS CONFLICT AROSE EITHER BY MISCOORD BTWN GND AND TWR, OR THE CESSNA MAY HAVE LINED UP WITH THE WRONG RWY, OR WAS CLRED TO LAND ON THE WRONG RWY. HAVING FLOWN INTO LAX SEVERAL TIMES (WHICH ALSO HAS CLOSELY SPACED PARALLEL RWYS) I AM AWARE OF THE IMPORTANCE OF XCHKING ACTUAL TFC WITH ATC XING CLRNCS. THIS BECOMES MORE CRITICAL WITH 'POS AND HOLD CLRNCS,' WHEN YOUR BACK IS TURNED TO LNDG TFC. IN THAT CASE, AT LEAST I'D BE ON TWR FREQ AND ABLE TO MONITOR LNDG TFC CLRNCS, I SUGGEST THAT ACFT TAXIING N OF TXWY B BE CTLED BY N TWR FREQ UNTIL ACROSS BOTH PARALLEL RWYS AND THEN BE HANDED OVER TO GND CTL.
