Narrative:

At lax the first officer and I briefed the ILS runway 25L approach and I flew that approach as published. During the approach, the controllers changed our airspeed several times to slower and slower speeds then faster again -- all due to an aircraft that had been put in front of us. Just prior to switching us over to the lax tower frequency, the controller thanked us for all our help with the aircraft separation ahead of us. Upon landing, ramp told us to contact socal. We called them on the phone and they said we may have been low over fuelr intersection. He was not sure if anything would come of it or if this was this an in-house item. I always try to fly every approach as published and correctly. Supplemental information from acn 450779: at approach control's request, airspeed was adjusted several times for spacing purposes. Approach mode was selected at the feather and the approach was completed. At handoff to tower, socal thanked us for our help. I acknowledged, and tower was contacted. After landing, ramp informed us that socal wanted to talk to us. The captain called upon arrival and was told that a possible altitude deviation occurred at fuelr. Not so, according to our instrumentation. We had received a TA just after turning inbound. The target didn't display an altitude or trend. I believe it was directly below us. The TA resolved itself and I never saw the target. On final, I pointed out to the captain an airplane on a parallel approach that appeared to be low. I checked our altitude thinking we might be high. All step-down altitudes were right on and the localizer and GS checked with raw data -- were also right on.

Title: ACR CREW QUESTIONED AFTER LNDG ABOUT BEING LOW OVER FUELR.

Narrative: AT LAX THE FO AND I BRIEFED THE ILS RWY 25L APCH AND I FLEW THAT APCH AS PUBLISHED. DURING THE APCH, THE CTLRS CHANGED OUR AIRSPD SEVERAL TIMES TO SLOWER AND SLOWER SPDS THEN FASTER AGAIN -- ALL DUE TO AN ACFT THAT HAD BEEN PUT IN FRONT OF US. JUST PRIOR TO SWITCHING US OVER TO THE LAX TWR FREQ, THE CTLR THANKED US FOR ALL OUR HELP WITH THE ACFT SEPARATION AHEAD OF US. UPON LNDG, RAMP TOLD US TO CONTACT SOCAL. WE CALLED THEM ON THE PHONE AND THEY SAID WE MAY HAVE BEEN LOW OVER FUELR INTXN. HE WAS NOT SURE IF ANYTHING WOULD COME OF IT OR IF THIS WAS THIS AN IN-HOUSE ITEM. I ALWAYS TRY TO FLY EVERY APCH AS PUBLISHED AND CORRECTLY. SUPPLEMENTAL INFO FROM ACN 450779: AT APCH CTL'S REQUEST, AIRSPD WAS ADJUSTED SEVERAL TIMES FOR SPACING PURPOSES. APCH MODE WAS SELECTED AT THE FEATHER AND THE APCH WAS COMPLETED. AT HDOF TO TWR, SOCAL THANKED US FOR OUR HELP. I ACKNOWLEDGED, AND TWR WAS CONTACTED. AFTER LNDG, RAMP INFORMED US THAT SOCAL WANTED TO TALK TO US. THE CAPT CALLED UPON ARR AND WAS TOLD THAT A POSSIBLE ALTDEV OCCURRED AT FUELR. NOT SO, ACCORDING TO OUR INSTRUMENTATION. WE HAD RECEIVED A TA JUST AFTER TURNING INBOUND. THE TARGET DIDN'T DISPLAY AN ALT OR TREND. I BELIEVE IT WAS DIRECTLY BELOW US. THE TA RESOLVED ITSELF AND I NEVER SAW THE TARGET. ON FINAL, I POINTED OUT TO THE CAPT AN AIRPLANE ON A PARALLEL APCH THAT APPEARED TO BE LOW. I CHKED OUR ALT THINKING WE MIGHT BE HIGH. ALL STEP-DOWN ALTS WERE RIGHT ON AND THE LOC AND GS CHKED WITH RAW DATA -- WERE ALSO RIGHT ON.
