A CRJ-200 FLT CREW ENCOUNTERED WAKE TURBULENCE FROM A B767 10 MILES AHEAD AND 500 FT ABOVE THEM.

Narrative

MY CREW AND I WERE OPERATING ON J-79. WE LEVELED FOR ABOUT 3-5 MINUTES AT FL310 AND I DID THE CRUISE CHECK. ATC THEN CLEARED US TO FL330. AS WE CLIMBED I NOTICED THE LIGHTS OF AN ACFT AT 12:00 AND OBSERVED HIM 10 MILES AHEAD AT FL330 ON TCAS. AS WE PASSED FL325 THE SHIP ROLLED L; THEN R; EXCEEDING 30 DEGS AND APCHING 45 DEGS BANK. THE FO QUICKLY PUT HIS HANDS ON THE CTLS AND THE AUTOPILOT DISCONNECTED. I NOTICED A R QUARTERING TAILWIND AND COMMANDED A R TURN TO EXIT THE WAKE; WHICH THE FO PERFORMED. I INFORMED ATC OF OUR SITUATION AND REQUESTED TO PARALLEL 5 MILES R OF COURSE. I CHKED WITH THE FLT ATTENDANT; WHO WAS NOT INJURED; DESPITE STRIKING HER HEAD ON THE OVERHEAD BIN. SHE RPTED NO INJURY TO PAX BUT SAID SHE HAD STEPPED AWAY FROM THE GALLEY CART; LEAVING IT OUT IN THE AISLE. AS A PRECAUTION; I MADE AN ANNOUNCEMENT EXPLAINING THE WAKE TURBULENCE AND INCLUDED THAT ANYONE RECEIVING AN INJURY SHOULD RPT IT. (NOBODY RPTED ANY INJURY TO THE CREW.) FURTHER CONVERSATION REVEALED THAT THE PRECEDING ACFT WAS A HEAVY 767. I BELIEVE THAT THIS ENCOUNTER WAS CAUSED BY CLBING ALONG AN AIRWAY CLOSE BEHIND A HEAVY ACFT IN A LIGHT QUARTERING TAILWIND. THIS HIGHLIGHTS THE IMPORTANCE OF THE WAKE TURBULENCE RESEARCH WHICH IS BEING DONE. IN THE FUTURE; I WILL PAY ATTENTION TO AIRPLANES MUCH FURTHER AHEAD.
