Flight Crew Regained Aircraft Control
Procedure; Environment - Non Weather Related
During our climb from FL320 to FL410; we encountered a moderate wake turbulence event which caused us to momentarily lose control of our aircraft. We experienced a sudden roll to the left of approximately 30 degrees; followed by a sudden roll to the right of approximately 70 degrees before regaining control. Our TCAS only identified one target which was located 12 NM at our 12 o'clock position and 1500 feet above us. We queried ATC as to the type of aircraft that was ahead of us and Los Angeles Center identified it as a B767. The winds were indicating 40 kts from a quartering tailwind position. Apparently; the [B767] was in level flight crossing from our right to left. Their wake turbulence had drifted from a position right of our course to one directly in front of us; causing this event. We continued our climb once control was regained and had no further issue. There was no damage to the aircraft and no injuries to passengers or crew aboard.
Gulfstream 100 Captain reported a momentary loss of control in climb at FL320 from a wake turbulence encounter from a B767 crossing in front of them.
