Narrative:
30 mins out of lax, we had a spoiler failure. This is a primary flight control and requires a reduced flap setting for landing as well as reduced roll control. We declared an emergency after talking with company dispatch and maintenance. We were on the civet arrival into lax, which uses ILS runway 25L localizer for lateral guidance with 4 stepdown fixes on the arrival and another 2 on the ILS runway 25L with vertical GS guidance being used at the FAF. These stepdown fixes are used to give clearance from 2 victor airways passing under the arrival. I know we made all the crossing restrs on the arrival, but am not sure about the 2 on the ILS itself prior to GS interception. We got very busy talking with company, briefing flight attendant, communicating emergency with ATC, and running approach checks. These were contributing factors to not being sure of where we intercepted and tracked GS. I should have asked for delay vectors to ensure that briefing was adequately covered and approach stepdowns noted. I believe I crossed all fixes at appropriate altitude, but I'm filing this NASA report to be sure.

Title: ALT XING RESTRS MISSED WHEN A CARJ PIC ADMITS TO POSSIBLE ALT VIOLATIONS ON THE APCH TO ILS RWY 25L AT LAX, CA.
Narrative: 30 MINS OUT OF LAX, WE HAD A SPOILER FAILURE. THIS IS A PRIMARY FLT CTL AND REQUIRES A REDUCED FLAP SETTING FOR LNDG AS WELL AS REDUCED ROLL CTL. WE DECLARED AN EMER AFTER TALKING WITH COMPANY DISPATCH AND MAINT. WE WERE ON THE CIVET ARR INTO LAX, WHICH USES ILS RWY 25L LOC FOR LATERAL GUIDANCE WITH 4 STEPDOWN FIXES ON THE ARR AND ANOTHER 2 ON THE ILS RWY 25L WITH VERT GS GUIDANCE BEING USED AT THE FAF. THESE STEPDOWN FIXES ARE USED TO GIVE CLRNC FROM 2 VICTOR AIRWAYS PASSING UNDER THE ARR. I KNOW WE MADE ALL THE XING RESTRS ON THE ARR, BUT AM NOT SURE ABOUT THE 2 ON THE ILS ITSELF PRIOR TO GS INTERCEPTION. WE GOT VERY BUSY TALKING WITH COMPANY, BRIEFING FLT ATTENDANT, COMMUNICATING EMER WITH ATC, AND RUNNING APCH CHKS. THESE WERE CONTRIBUTING FACTORS TO NOT BEING SURE OF WHERE WE INTERCEPTED AND TRACKED GS. I SHOULD HAVE ASKED FOR DELAY VECTORS TO ENSURE THAT BRIEFING WAS ADEQUATELY COVERED AND APCH STEPDOWNS NOTED. I BELIEVE I CROSSED ALL FIXES AT APPROPRIATE ALT, BUT I'M FILING THIS NASA RPT TO BE SURE.
