Narrative:
We had a wake turbulence encounter on the visual approach to runway 17. We were following an airbus at a distance of about 3 miles. Both aircraft were instructed to maintain 160 KTS to 4 mile final. The airbus slowed prematurely; I started to slow and configure for landing. The autopilot was engaged and I noticed that the aircraft began banking left. I disconnected the autopilot and attempted to keep the wings level. The aircraft did not respond to my control inputs and then began an immediate roll to the right stopping at about 50 degrees of bank. Within 5 seconds the aircraft returned to level flight and we executed a go around and eventually landed with no further incident. The close proximity to the airbus we were following combined with the tailwind condition at altitude were the main causes of the event.
