A COURSE DEV ON THE SKEBR RNAV 2 ARR TO LAS; NV.

Narrative

DEV FROM PUBLISHED ARR PROC. THE SKEBR RNAV 2 ARR WAS PROGRAMMED INTO THE FMC WHILE AT THE GATE IN LAX. RWY 25L WAS ENTERED WHILE AIRBORNE; AFTER PASSING MISEN; AND FIXES VERIFIED ON THE LEGS PAGE. AFTER PASSING SKEBR; ATC ISSUED A HDG OF 340 DEGS; AND I LOOKED DOWN AT THE BOX TO SEE THE AIRPLANE FLYING SKEBR DIRECT SHAND. IT HAD DROPPED KEPEC; IPUMY; POVOC; AND KIMME. ATC STATED THAT THERE WAS NOT A PROB; BUT ASKED WHERE WE WERE HEADED AFTER SKEBR. HE INFORMED US THAT 8 OTHER COMPANY ACFT HAD DONE THE SAME THING THAT SAME DAY; AND ASKED ME TO CALL TRACON UPON ARR. ON THE PHONE WITH THE LAS TRACON SUPVR; I WAS TOLD THAT WE WERE NUMBER 9 IN A STRING OF COMPANY DEVS THAT DAY ALONE. NO OTHER CARRIERS HAVE HAD THE PROB. THE SUPVR HAD SPOKEN WITH SEVERAL OF OUR CAPTS THAT DAY AND FELT THAT THE PROB OCCURRED WHEN THE FMC WAS PROGRAMMED WITH THE ARR RWY WHILE AIRBORNE. IF PROGRAMMED ON THE GND BEFORE DEP; THE BOX DID NOT DROP ANY FIXES. NO PLT'S DISCRETION WERE FILED; BUT I WAS ASKED TO PASS THE INFO ON TO THE COMPANY. ALTHOUGH I SEEM TO REMEMBER CONFIRMING THE FIXES AFTER I PROGRAMMED IN THE ARR RWY; APPARENTLY I DID NOT.
