FLC FLIES 300 FT LOW OVER FUELR INTXN AT LAX.

Narrative

WE WERE CLRED FOR THE CIVET 1 ARR TO LAX. ATIS SAID RWY 25L GS UNUSABLE BEYOND 10 MI. APCH CTL THEN CLRED US FOR THE ILS APCH TO RWY 25L AT ARNES INTXN. AS WE CROSSED ARNES INTXN AT 10000 FT THE GS WAS CTRED. I THEN SELECTED APCH MODE ON THE AUTOPLT SINCE I THOUGHT THE GS WAS OK. THE AUTOPLT WAS SMOOTH AND I SAW NO GS FLAGS. APCH CTL INFORMED ME I CROSSED FUELR INTXN AT 7700 FT INSTEAD OF 8000 FT. I WAS BUSY WITH SPD REDUCTIONS AND TFC AND DID NOT THINK ABOUT THE STEPDOWNS ON THE APCH SINCE I WAS CLRED FOR THE ILS RWY 25L APCH AT ARNES INTXN. I BELIEVE A REMINDER FROM THE CTLR WOULD HAVE PREVENTED THIS SINCE THE CLRNC; 'CLRED FOR THE RWY 25L ILS AT ARNES' AND AT ARNES AT 10000 FT BOTH THE LOC AND GS WERE CTRED LED ME TO THINK ALL I HAD TO DO WAS KEEP THE LOC AND GS CTRED; WHICH I DID. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR FELT THAT ANYTIME AN ACFT IS CLRED FOR AN ILS APCH; ALL XING ALTS ARE CLR. FURTHER; HE FELT THE GS HAD A BEND IN IT WHICH TOOK HIM TOO LOW WHICH CAUSED HIM TO INTRUDE ON THE AIRSPACE AT FUELR. RPTR WAS INFORMED THAT THE AIRSPACE BELOW FUELR WOULD ALWAYS BE VIOLATED IF AN ACFT WERE TO BE ON THE GS OF THE ILS. RPTR WAS ASKED THAT IF THE CTLR WERE TO MAKE THE STATEMENT; 'CLRED FOR THE ILS TO RWY 25L; COMPLY WITH ALL ALT RESTRS;' WOULD THAT MAKE HIM MORE ALERT TO COMPLY WITH ALL ALT RESTRS. HE REPLIED THAT IT WOULD RING A BELL AND KEEP HIM AT THE PROPER ALTS ALL THE WAY DOWN THE ILS.
