Narrative:

We were flying the blue ridge 3 arrival to dfw airport (the captain was flying). Approaching the hamak fix, at 11000 ft, 250 KTS, regional approach issued an advisory for traffic at our 2 oþclock position climbing from below. There were numerous targets registering on the TCASII, several of which were visible at or above our altitude. We were VMC at 11000 ft just above a cloud deck which was hiding the called traffic. Very shortly after the ATC TA, our TCASII issued an aural warning, þmonitor vertical spdþ, followed by þclb, clbþ. The first officer spotted the traffic at our 3-4 oþclock position, passing beneath us. Shortly thereafter the TCASII announced, þclr of conflictþ. The controller then issued instructions for a turn to 170 degrees and further descent. A few moments later, the controller queried us about our speed which was still 250 KTS. The controller pointed out that the STAR required 210 KTS at hamak and a turn to a 170 degree heading. The first officer acknowledged and we immediately slowed to 210 KTS. There was no further discussion with the controller and we began receiving vectors to the final approach course. The approach and landing were uneventful. As so, I was distracted from monitoring the STAR by my duties at the panel as well as helping the maintain outside vigilance. The ctlrþs TA coupled with the TCASII warning diverted everyoneþs attention outside the cockpit at a time when the STAR required specific actions. This resulted in the failure to slow to 210 KTS by hamak and failure to accomplish the turn to 170 degrees prior to the ctlrþs instruction. Supplemental information from acn 199894: a copy of this STAR chart is being submitted with this narrative as it is in my mind extremely cluttered. Not the proximity of the 250 KTS printed just above the word hamak. Another old ingredient in this incident was similar call signs. There both air carrier xþs and air carrier yþs 1234 flts on the approach frequency. We were advised of this when the frequency was tuned.

Title: HDG TRACK SPD DEV FROM APCH PROC STAR THERE WERE TCASII RA IS CITED AS FLC DISTR TFC WATCH.

Narrative: WE WERE FLYING THE BLUE RIDGE 3 ARR TO DFW ARPT (THE CAPT WAS FLYING). APCHING THE HAMAK FIX, AT 11000 FT, 250 KTS, REGIONAL APCH ISSUED AN ADVISORY FOR TFC AT OUR 2 OþCLOCK POS CLBING FROM BELOW. THERE WERE NUMEROUS TARGETS REGISTERING ON THE TCASII, SEVERAL OF WHICH WERE VISIBLE AT OR ABOVE OUR ALT. WE WERE VMC AT 11000 FT JUST ABOVE A CLOUD DECK WHICH WAS HIDING THE CALLED TFC. VERY SHORTLY AFTER THE ATC TA, OUR TCASII ISSUED AN AURAL WARNING, þMONITOR VERTICAL SPDþ, FOLLOWED BY þCLB, CLBþ. THE FO SPOTTED THE TFC AT OUR 3-4 OþCLOCK POS, PASSING BENEATH US. SHORTLY THEREAFTER THE TCASII ANNOUNCED, þCLR OF CONFLICTþ. THE CTLR THEN ISSUED INSTRUCTIONS FOR A TURN TO 170 DEGS AND FURTHER DSCNT. A FEW MOMENTS LATER, THE CTLR QUERIED US ABOUT OUR SPD WHICH WAS STILL 250 KTS. THE CTLR POINTED OUT THAT THE STAR REQUIRED 210 KTS AT HAMAK AND A TURN TO A 170 DEG HDG. THE FO ACKNOWLEDGED AND WE IMMEDIATELY SLOWED TO 210 KTS. THERE WAS NO FURTHER DISCUSSION WITH THE CTLR AND WE BEGAN RECEIVING VECTORS TO THE FINAL APCH COURSE. THE APCH AND LNDG WERE UNEVENTFUL. AS SO, I WAS DISTRACTED FROM MONITORING THE STAR BY MY DUTIES AT THE PANEL AS WELL AS HELPING THE MAINTAIN OUTSIDE VIGILANCE. THE CTLRþS TA COUPLED WITH THE TCASII WARNING DIVERTED EVERYONEþS ATTN OUTSIDE THE COCKPIT AT A TIME WHEN THE STAR REQUIRED SPECIFIC ACTIONS. THIS RESULTED IN THE FAILURE TO SLOW TO 210 KTS BY HAMAK AND FAILURE TO ACCOMPLISH THE TURN TO 170 DEGS PRIOR TO THE CTLRþS INSTRUCTION. SUPPLEMENTAL INFO FROM ACN 199894: A COPY OF THIS STAR CHART IS BEING SUBMITTED WITH THIS NARRATIVE AS IT IS IN MY MIND EXTREMELY CLUTTERED. NOT THE PROX OF THE 250 KTS PRINTED JUST ABOVE THE WORD HAMAK. ANOTHER OLD INGREDIENT IN THIS INCIDENT WAS SIMILAR CALL SIGNS. THERE BOTH ACR XþS AND ACR YþS 1234 FLTS ON THE APCH FREQ. WE WERE ADVISED OF THIS WHEN THE FREQ WAS TUNED.
