Regional Jet 700 ER/LR (CRJ700)
Flight Crew Air Transport Pilot (ATP)
Deviation - Speed All Types; Inflight Event / Encounter Wake Vortex Encounter
Flight Crew Executed Go Around / Missed Approach; Flight Crew Took Evasive Action
Environment - Non Weather Related
During our approach we were conducting an ILS approach. We were following a heavy 767. The weather was reporting light snow; calm winds; and a visibility of 3 SM. The aircraft preceding the 767 had to use the entire runway to stop and taxi off; which caused tower to send the heavy 767 around. We were about 5 NM behind the heavy 767. When I heard the heavy 767 go around I went ahead and briefed the go around procedure with the CA since I expected there to be a possibility of hitting its wake. The entire approach was stable; and the 1000 ft call was made; to which I responded 'stable.' At about 900 ft AGL we hit the wake from the heavy 767; which caused us to [rock] back and forth; and have wide airspeed variations. I called for a go around since I did not know how much worse it may get. Going around allowed us to power out of the wake and leave it before the situation got any worse. There were no other significant events after the go around.
CRJ-700 First Officer reported executing a go-around on final approach after encountering wake turbulence in trail of a heavy B767 that had executed a go-around as well.
