CL60 EXPERIENCES WAKE TURB ON KAYOH STAR TO SNA. POSSIBLY FROM B767 DSNDING FOR LGB 12 MI AHEAD.

Narrative

WE WERE 1 MI FROM KAYOH ON THE KAYOH4 ARR INTO SNA; AND APPROX 12 MI BEFORE HAD BEEN GIVEN A 260 DEG HDG AFTER XING KAYOH. THE FO WAS FLYING. JUST PASSING KAYOH AND WE WERE GIVEN A DSCNT TO 6000 FT AND WERE GETTING READY FOR OUR TURN TO 260 DEG HDG AND IMMEDIATELY STARTED TO EXPERIENCE A LIGHT TO MODERATE CHOP FOLLOWED BY A SLIGHT ROLL TO THE R AND L. THE FO WHO WAS FLYING DISCONNECTED THE AUTOPLT AND TRIED TO INITIATE THE TURN TO THE HDG OF 260 DEGS; BUT WAS UNABLE TO INITIATE THE TURN DUE TO THE WAKE TURB AS HE WAS TRYING TO GET THE R TURN STARTED; BUT WE WERE FIGHTING AGAINST A ROLL TO THE L. THE BANK ANGLE VARIED ONCE TO APPROX 30 DEGS. WE LEVELED OUT AT APPROX 7600 FT; THINKING WE WOULD STAY ABOVE THE WAKE TURB; AS WE THOUGHT IT WAS FROM ANOTHER AIRPLANE WE WERE FOLLOWING INTO SNA. THE WINDS AT THE ALT WE WERE AT WERE OUT OF THE NNW AT 3 KTS. AFTER APPROX 10 SECONDS WE WERE OUT OF THE WAKE TURB; AND QUERIED SOCAL APCH AS TO WHAT PLANE WE WERE FOLLOWING AND HOW CLOSE HE WAS; AS WE DID NOT SEE ANOTHER PLANE ON OUR TCAS AT THE 10 MI SCALE. SOCAL RESPONDED THAT THERE WAS A B767 ON THE ARR TO LGB THAT WE HAD BEEN FOLLOWING; BUT HE WAS 12 MI IN FRONT OF US. WE ADVISED HIM THAT WE JUST EXPERIENCED WAKE TURB FROM THE ACFT. SOCAL PROCEEDED TO JUST GIVE US OUR DSCNT CLRNC AGAIN; AND WE RESPONDED THAT WE WOULD WAIT A FEW SECONDS TO ENSURE WE WOULD NOT EXPERIENCE ANY FURTHER WAKE.
