FLT CREW OF LGT DSND WITHOUT CLRNC ON BUNTR ARR TO PHX.

Narrative

FLT OPERATING TO PHX. PRIOR CLRNC WAS 'CLRED DIRECT ZUNI MAINTAIN FL310.' WE WERE GIVEN FREQ CHANGE (ZAB) 132.9. NEXT CTLR SAID CLRED 'DIRECT SLIDER INTXN' (BUNTR1). WE LOADED BUNTR 1 ARR IN FMS. WE WERE ASKED TO MAINTAIN BEST FORWARD SPD AND CROSS SLIDER INTXN AT FL290. JUST PRIOR TO SLIDER INTXN CTLR SAID 'CLRED DIRECT SLIDER; AFTER SLIDER CLRED DIRECT HOMRR INTXN; RESUME BUNTR 1 ARR.' HOMRR INTXN HAS AN 'EXPECT TO CROSS AT 12000 FT 250 KTS' NOTE. WE PROGRAMMED THAT RESTR IN THE FMS. WE HAD BEEN FLYING THIS ARR ALL WK AND WERE ALWAYS GIVEN THE 12000 FT 250 KTS RESTR AT HOMRR. PASSING SLIDER INTXN WE WERE 'HIGH' ON THE PROFILE TO MAKE THE PLANNED 12000 FT 250 KTS; ESPECIALLY SINCE WE WERE TOLD TO MAINTAIN MAX FORWARD SPD! THE AIRPLANE STARTED ITS DSCNT (FROM FL290). PASSING FL270 ZAB SAID 'ACR X SAY ALT.' WE REPLIED PASSING FL270 FOR 1-2 THOUSAND. CTLR SAID 'WHO GAVE YOU CLRNC TO DSND?' I REPLIED WE WERE CLRED VIA THE STAR. BOTH THE CAPT AND I REALIZED OUR MISTAKE AT THAT TIME. CTLR SAID 'LEVEL OFF AT FL240; I'LL HAVE LOWER FOR YOU SHORTLY.' WE ASKED IF THERE WAS A PROB. CTLR REPLIED NO; BUT THERE COULD HAVE BEEN. CTLR SAID ABQ IS WORKING ON GETTING THE WORDING CHANGED ON THE BUNTR 1 ARR. CTLR SAID THIS HAPPENS A LOT. FLYING THIS ARR ALL WK AND GETTING THE SAME CLRNC CAUSED US TO GET COMPLACENT.
