We know in one case that the VS mounting lugs failed laterally, all at once, across many layers of composite material, in AA587. This must have taken the structural engineers somewhat by surprise.
Not so.
From the Airbus FCOM Bulletin 815/1
The Rudder should not be used:
- To induce roll
- To counter roll induced by any type of turbulance
Whatever the airborne flight conditions may be, full or nearly full opposite rudder pedal inputs must not be applied. Such inputs can lead to loads higher than the limit, and can result in structural damage or failure
The rudder travel limiter system is not designed to prevent structural damage or failure in the event of such rudder system inputs
