Narrative:

CL60 10 mi in trail to B767. Aircraft (CL60) reported 30 degree bank and autoplt kicked off. CL60 at first thought it was turbulence and requested higher. There were no other complaints of even chop. The controller I was relieving told me about incident and speculated that it might be wake turbulence. About that time the pilot said the same thing and told us about the bank and autoplt (he first said a jolt of turbulence). I decided to report the incident and suggested to the pilot he do the same. It was also reported to my supervisor. I have had many instances of wake turbulence (more like light to moderate chop) reported 10 mi behind heavy aircraft, but this is the first near loss of control.

Title: CL60 ACFT IN CRUISE HIT WAKE TURB FROM B767 10 MI AHEAD. AUTOPLT KICKED OFF AND ACFT BANKED 30 DEGS BEFORE RPTR CAPT COULD MAINTAIN CTL OF THE ACFT.

Narrative: CL60 10 MI IN TRAIL TO B767. ACFT (CL60) RPTED 30 DEG BANK AND AUTOPLT KICKED OFF. CL60 AT FIRST THOUGHT IT WAS TURB AND REQUESTED HIGHER. THERE WERE NO OTHER COMPLAINTS OF EVEN CHOP. THE CTLR I WAS RELIEVING TOLD ME ABOUT INCIDENT AND SPECULATED THAT IT MIGHT BE WAKE TURB. ABOUT THAT TIME THE PLT SAID THE SAME THING AND TOLD US ABOUT THE BANK AND AUTOPLT (HE FIRST SAID A JOLT OF TURB). I DECIDED TO RPT THE INCIDENT AND SUGGESTED TO THE PLT HE DO THE SAME. IT WAS ALSO RPTED TO MY SUPVR. I HAVE HAD MANY INSTANCES OF WAKE TURB (MORE LIKE LIGHT TO MODERATE CHOP) RPTED 10 MI BEHIND HVY ACFT, BUT THIS IS THE FIRST NEAR LOSS OF CTL.
