takata posted the following summary of an A310 LOC.
Date.............ft/mn....Level....Dur....Dist..Type...-> Cause
23.03.1994..12,000..FL310..156s...3 NM..A310...-> Spiral-spin / roll upset
From what I understand, the aircraft departed FL310 cruise altitude into a gentle right-hand turn which then became a high bank roll and dive with the aircraft turning through 180 degrees before making a partial recovery. Control was finally lost at around FL130 and the aircraft did a combo spiral dive and finished up spinning in.
The point I am making is that any number of manoeuvres, controlled or otherwise, could conspire to place the aircraft close to the point that LOC occurred.
