Narrative:

Approximately 1300 ft AGL coupled approach, aircraft rolled right 40 degrees, then nose low 10 degrees. Disconnected autoplts. Use of full opposite deflection regained control of aircraft. Performed abnormal procedures for altitude low altitude warning. Direct low altitude warning landing uneventful. Post-flight printout showed 2 malfunctions. Not exactly sure now which ones, however I recall adirv 2 fail and fcdc 1.
