Narrative:
On final approach ILS to runway 16 pns, after before landing checklist performed (which verifies flap position), at approximately 600-800' AGL, approximately 146 KTS. Stick shaker activated. Airspeed immediately checked while initiating a go around. First officer was flying the aircraft. We saw that the inbound flaps had returned to up. We trouble-shot the system, elected to return to atl and use long runway because inboard flaps were failed, now in the up position. Made landing in atl with led's and outboard flaps at 30 degrees. Approach and landing uneventful.
