Narrative:

While flying the arrival into an international airport; aircraft experienced a momentary airframe buffet followed quickly by a severe left roll and nose down pitch. Aircraft was leveling at 11000 ft per ATC and had slowed to 210 KIAS assigned. Immediate upset recovery was initiated with minimal loss of altitude. Passenger were seated with seat belts fastened. PIC notified ATC of upset and asked if they had any traffic ahead. ATC indicated a B767 was 10 miles ahead. There had been no traffic advisories concerning the heavy aircraft in front of us. Given the precise navigation tracks associated with FMS/GPS operations and rvsm airspace; the potential for wake turbulence upsets is increasing within domestic airspace. It is critical for crews to remain alert for potential conflicts especially in high density arrival areas. Crews are also encouraged to report all upset occurrences so the FAA can continue to track.callback conversation with reporter revealed the following information: the reporter had received upset training provided by his company and found it invaluable during this situation.

Title: THE WAKE OF A B767 IS RPTED TO HAVE CAUSED THE UPSET OF A FALCON 50 FOLLOWING 10 MILES BEHIND.

Narrative: WHILE FLYING THE ARR INTO AN INTERNATIONAL ARPT; ACFT EXPERIENCED A MOMENTARY AIRFRAME BUFFET FOLLOWED QUICKLY BY A SEVERE L ROLL AND NOSE DOWN PITCH. ACFT WAS LEVELING AT 11000 FT PER ATC AND HAD SLOWED TO 210 KIAS ASSIGNED. IMMEDIATE UPSET RECOVERY WAS INITIATED WITH MINIMAL LOSS OF ALTITUDE. PAX WERE SEATED WITH SEAT BELTS FASTENED. PIC NOTIFIED ATC OF UPSET AND ASKED IF THEY HAD ANY TFC AHEAD. ATC INDICATED A B767 WAS 10 MILES AHEAD. THERE HAD BEEN NO TFC ADVISORIES CONCERNING THE HEAVY ACFT IN FRONT OF US. GIVEN THE PRECISE NAV TRACKS ASSOCIATED WITH FMS/GPS OPERATIONS AND RVSM AIRSPACE; THE POTENTIAL FOR WAKE TURBULENCE UPSETS IS INCREASING WITHIN DOMESTIC AIRSPACE. IT IS CRITICAL FOR CREWS TO REMAIN ALERT FOR POTENTIAL CONFLICTS ESPECIALLY IN HIGH DENSITY ARR AREAS. CREWS ARE ALSO ENCOURAGED TO RPT ALL UPSET OCCURRENCES SO THE FAA CAN CONTINUE TO TRACK.CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR HAD RECEIVED UPSET TRAINING PROVIDED BY HIS COMPANY AND FOUND IT INVALUABLE DURING THIS SITUATION.
