Narrative:

We were on the atl 26R ILS prm approach. We were at 5;000 about 2 NM east of hainz and approximately 4 NM behind a small airbus when we hit significant wake turbulence. The pilatus rumbled then very quickly banked left 30-40 degrees and pitched down five to ten degrees. I quickly disconnected the autopilot; leveled the wings and leveled the pitch. We regained control of the aircraft and continued the approach. We ended up about 100 ft above our assigned altitude but no deviation was noted by ATC. We landed uneventfully; we were not able to notify ATC due to frequency congestion.
