Narrative:
We were just leveling 9000 MSL approaching suzzi on civet 2 profile descent when we hit violent wake turbulence which rolled us to the right past 30 degrees of bank. I told first officer to ease it to the right, checked TCASII and looked visually, saw no apparent traffic. I called ATC, told him deviating right, he said call approach. I switched to approach, told him of deviation and he cleared us for ILS 24R which we were near to intercepting. We then flew a normal ILS 24R to landing. This was the worst wake turbulence I have experienced, and it lasted longer than expected through our turn.

Title: ACR MLG IN WAKE ENCOUNTER PERFORMS A HDG TRACK DEV TO ESCAPE THE WAKE TURB.
Narrative: WE WERE JUST LEVELING 9000 MSL APCHING SUZZI ON CIVET 2 PROFILE DSCNT WHEN WE HIT VIOLENT WAKE TURB WHICH ROLLED US TO THE R PAST 30 DEGS OF BANK. I TOLD FO TO EASE IT TO THE R, CHKED TCASII AND LOOKED VISUALLY, SAW NO APPARENT TFC. I CALLED ATC, TOLD HIM DEVIATING R, HE SAID CALL APCH. I SWITCHED TO APCH, TOLD HIM OF DEV AND HE CLRED US FOR ILS 24R WHICH WE WERE NEAR TO INTERCEPTING. WE THEN FLEW A NORMAL ILS 24R TO LNDG. THIS WAS THE WORST WAKE TURB I HAVE EXPERIENCED, AND IT LASTED LONGER THAN EXPECTED THROUGH OUR TURN.
