The Cloncurry Incident report states:
"A rapid application of a large amount of right wing down aileron control at speeds in the vicinity of the normal cruising speed could produce torsional loading in the left wing in excess of the design strength of the wing and result in
wing failure consistent with that which occurred in this accident."
So what do we consider to be a "safe" amount of control deflection at speeds above Manouvring Speed?
