Narrative:
Civet 2 arrival lax, LNAV/VNAV in use. Received at least 4 speed adjustments on arrival. Last speed assigned was 250 KTS. Below 10000 ft VNAV slows to 240 KTS to avoid overspd. Selected flaps to 1 degree and EICAS displayed 'trailing edge flap disagreement' with no flap movement. Began the abnormal checklist and when preparing to advise ATC of speed reduction, we were given frequency change. Next frequency very congested and while working on the problem, I failed to advise approach control of speed, controller very cooperative and made flaps 20 degree landing per checklist. Called ATC watch supervisor. Supplemental information from acn 388643: I requested flaps 1 degree and EICAS displayed 'trailing edge disagreement.' we then followed our procedures for problem. We started slowing to 200 KTS. We were going to advise ATC as soon as possible, but frequency was congested. Then received frequency change. We told next controller of slowing and problem. We extended flaps using alternate procedures. Landing normal with 20 degrees flaps. Ground control gave phone number to contact watch supervisor on approach control.

Title: A B757-200 FLYING THE CIVET STAR INTO LAX, HAS AN EICAS MESSAGE THAT THE TRAILING EDGE FLAPS ARE NOT EXTENDING. FLC SLOWS ACFT TO ACCOMMODATE THE FLAP EXTENSION AND CHANGE OF SPD IS NOT ANNOUNCED TO TRACON.
Narrative: CIVET 2 ARR LAX, LNAV/VNAV IN USE. RECEIVED AT LEAST 4 SPD ADJUSTMENTS ON ARR. LAST SPD ASSIGNED WAS 250 KTS. BELOW 10000 FT VNAV SLOWS TO 240 KTS TO AVOID OVERSPD. SELECTED FLAPS TO 1 DEG AND EICAS DISPLAYED 'TRAILING EDGE FLAP DISAGREEMENT' WITH NO FLAP MOVEMENT. BEGAN THE ABNORMAL CHKLIST AND WHEN PREPARING TO ADVISE ATC OF SPD REDUCTION, WE WERE GIVEN FREQ CHANGE. NEXT FREQ VERY CONGESTED AND WHILE WORKING ON THE PROB, I FAILED TO ADVISE APCH CTL OF SPD, CTLR VERY COOPERATIVE AND MADE FLAPS 20 DEG LNDG PER CHKLIST. CALLED ATC WATCH SUPVR. SUPPLEMENTAL INFO FROM ACN 388643: I REQUESTED FLAPS 1 DEG AND EICAS DISPLAYED 'TRAILING EDGE DISAGREEMENT.' WE THEN FOLLOWED OUR PROCS FOR PROB. WE STARTED SLOWING TO 200 KTS. WE WERE GOING TO ADVISE ATC ASAP, BUT FREQ WAS CONGESTED. THEN RECEIVED FREQ CHANGE. WE TOLD NEXT CTLR OF SLOWING AND PROB. WE EXTENDED FLAPS USING ALTERNATE PROCS. LNDG NORMAL WITH 20 DEGS FLAPS. GND CTL GAVE PHONE NUMBER TO CONTACT WATCH SUPVR ON APCH CTL.
