Narrative:
During the approach at knoxville on the ILS runway 23R turning on to the approach we encountered a ground proximity warning. Both pilots pulled up on the yoke and the controller was told of our GPWS. He cleared us to 4000 ft by the time we got the plane to level off we were through 4600 ft. We leveled the aircraft at 4000 ft and tried another approach to knoxville with no GPWS this time. Don't know what caused the GPWS or why.
