Don't understand this comment. What manoeuvre should the OP look for in the AFM? Steady heading sideslip? Won't be there. But for example, the steady heading sideslip component of a maximum crosswind takeoff or landing would be far more demanding than what the OP is proposing. Perhaps a complete engine failure at maximum altitude and maximum continuous power? That will result in a far more demanding situation than that proposed but it is a manoeuvre for which the aircraft is certificated. There is no procedure in any AFM concerning, say, using full control deflection - if it is required, the pilot does it - staying within the aircraft certification limits. Probably the most important in this case would be Va restrictions but it could be something like a buffet boundary, which won't be a AFM approved procedure.
