ARTCC RADAR CTLR INTERVENTION - THE FLC WAS NOT GOING TO MAKE THEIR XING RESTR SO THE CTLR GAVE THEM A NEW ROUTING AND ALT AND BROUGHT THEM BACK ONTO COURSE IN GOOD SHAPE FOR THE APCH.

Narrative

CROWE 6 ARR; SLC-LAS; I WAS FLYING THE ACFT ON THE MILFORD ROUTING WHEN WE WERE GIVEN DIRECTIONS TO INTERCEPT THE RWY 25L LOC AND CROSS CROWE AT 10000 FT MSL. SHORTLY PRIOR TO THIS; I HAD ENTERED CROWE INTO OUR FMC AND SET UP FOR A DSCNT OF 320 KTS TO SLOW TO 250 KTS BY CROWE. SINCE WE HAD BEEN GIVEN AN INTERCEPT FOR THE LOC (NO DME) OUR OTHER NAV AID WAS SET UP FOR THAT. AFTER SWITCHING FROM MILFORD VOR TO GOFFS; I NOTICED THAT INITIALLY WE WERE NOT RECEIVING ANY DME. IT WAS DURING THIS TIME THAT OUR ONLY GUIDANCE FOR OUR INITIAL DSCNT WAS COMING FROM OUR FMC WITH CROWE SET IN. LATER EXAMINATIONS SHOWED THAT THE COORDINATES FOR CROWE HAD BEEN INCORRECTLY INSERTED INTO THE FMC; GIVING AN INCORRECT START DSCNT POINT. BECAUSE THE LOC FREQ CONTAINS NO DME AND WE WERE NOT RECEIVING DME FROM GOFFS AT THE TIME; OUR ONLY REF FOR DSCNT WAS FROM OUR FMC; WHICH AS IT TURNS OUT WAS INCORRECT. TO COMPOUND MATTERS; WE BEGAN TO ENCOUNTER CONTINUOUS LIGHT TO MODERATE TURB. ONCE WE STARTED OUR DSCNT; OUR RATE WAS RESTRICTED FURTHER DUE TO THE TURB. SOON THEREAFTER ZLA CALLED AND ASKED IF WE WERE GOING TO MAKE CROWE AT 10000 FT. THEY OBVIOUSLY KNEW WE WEREN'T AND TURNED US OUT OF THE ARR AT FL230 APPROX 8 NM FROM CROWE. AFTER A STEPPED DOWN DSCNT; WE REJOINED THE ARR INTO LAS. WE DID CONTACT THE DUTY SUPVR AT LOS ANGELES TO APOLOGIZE AND HE STATED THAT THIS WAS A VERY COMMON OCCURRENCE AND THAT WE COULD BE ASSURED THAT THEY HAD NO ATTN OF FILING ANY ACTIONS. ALTHOUGH WE WERE RELIEVED THAT WE WEREN'T IN TROUBLE; THE FACT THAT HE SAID THIS THING WAS A COMMON OCCURRENCE LEADS ME TO BELIEVE THAT PERHAPS IF DME WERE ASSOCIATED WITH THE LOC THAT THIS COULD HAVE BEEN AVOIDED ALL TOGETHER.
