Perhaps many of you are not familiar with the American Airlines 587 crash in NY?
Ask uncle Google, but some excerpts from the NTSB follow,
"Based on interviews with the pilot community, what we've learned is that appears that many pilots have not been made aware that full rudder inputs, as I say, under certain conditions can jeopardy the integrity of the vertical fin, and that in some airliner models, rudder deflections can be achieved with relatively small pedal movements and comparatively light forces, and by this, what I mean is that in some aircraft, what you find is that pedal movements of inch and a half, no more, 30 pounds of pressure, which is really not much, can achieve very significant movement of the rudder, and therefore, really do cause concern" TOM HAUTER, NTSB
and,
"The two safety recommendations address the fact that many pilot training programs do not include information about the structural certification requirements for the rudder and vertical stabilizer on transport-category airplanes. Significantly, full rudder inputs even at speeds below the design maneuvering speed, may result in structural loads that exceed certification requirements." -
