Narrative:

On skebr arrival into las, at skebr aircraft was noted turning right on approximately 040 degree heading rather than a hard left turn to kepec. Before we could get kepec manually entered into FMC, controller noted our course deviation and gave us vectors for remainder of arrival (captain was flying). Recreating circumstances, I discovered that waypoints between skebr and shand on skebr arrival had not been placed into FMC. Further investigation showed note on flight release that I had missed in san diego stating that skebr and idale arrival rtes in FMC were missing these points. In retrospect, I realize now that after selecting runway 25L as the runway, I closed up shand to the top of its page without going to previous page to verify which waypoint it was following. I also missed the note at the bottom of the release which would have alerted us to the problem. Note was somewhat 'hidden' in that it followed the note on runway 25L arrs which has been on releases for a long time -- making it easy to think it's the same note I've seen a thousand times. I'll be making sure I read those more thoroughly in the future. We also could have helped ourselves by immediately asking for vectors from the controller when we saw we had missed the turn rather than wasting time trying to enter the missing point. Having the FMC on the approach plate would have been helpful as well to at least get us turning in the correct direction.

Title: A COURSE DEV ON THE SKEBR RNAV 2 ARR TO LAS, NV, QUICKLY CORRECTED BY ATC.

Narrative: ON SKEBR ARR INTO LAS, AT SKEBR ACFT WAS NOTED TURNING R ON APPROX 040 DEG HDG RATHER THAN A HARD L TURN TO KEPEC. BEFORE WE COULD GET KEPEC MANUALLY ENTERED INTO FMC, CTLR NOTED OUR COURSE DEV AND GAVE US VECTORS FOR REMAINDER OF ARR (CAPT WAS FLYING). RECREATING CIRCUMSTANCES, I DISCOVERED THAT WAYPOINTS BTWN SKEBR AND SHAND ON SKEBR ARR HAD NOT BEEN PLACED INTO FMC. FURTHER INVESTIGATION SHOWED NOTE ON FLT RELEASE THAT I HAD MISSED IN SAN DIEGO STATING THAT SKEBR AND IDALE ARR RTES IN FMC WERE MISSING THESE POINTS. IN RETROSPECT, I REALIZE NOW THAT AFTER SELECTING RWY 25L AS THE RWY, I CLOSED UP SHAND TO THE TOP OF ITS PAGE WITHOUT GOING TO PREVIOUS PAGE TO VERIFY WHICH WAYPOINT IT WAS FOLLOWING. I ALSO MISSED THE NOTE AT THE BOTTOM OF THE RELEASE WHICH WOULD HAVE ALERTED US TO THE PROB. NOTE WAS SOMEWHAT 'HIDDEN' IN THAT IT FOLLOWED THE NOTE ON RWY 25L ARRS WHICH HAS BEEN ON RELEASES FOR A LONG TIME -- MAKING IT EASY TO THINK IT'S THE SAME NOTE I'VE SEEN A THOUSAND TIMES. I'LL BE MAKING SURE I READ THOSE MORE THOROUGHLY IN THE FUTURE. WE ALSO COULD HAVE HELPED OURSELVES BY IMMEDIATELY ASKING FOR VECTORS FROM THE CTLR WHEN WE SAW WE HAD MISSED THE TURN RATHER THAN WASTING TIME TRYING TO ENTER THE MISSING POINT. HAVING THE FMC ON THE APCH PLATE WOULD HAVE BEEN HELPFUL AS WELL TO AT LEAST GET US TURNING IN THE CORRECT DIRECTION.
