The National Transportation Safety Board recommends that the Federal. .Aviation Administration:
Require the manufacturers and operators of transport-category airplanes to. .establish and implement pilot training programs that: (1) explain the. .structural certification requirements for the rudder and vertical stabilizer. .on transport-category airplanes; (2) explain that a full or nearly full. .rudder deflection in one direction followed by a full or nearly full rudder. .deflection in the opposite direction, or certain combinations of sideslip. .angle and opposite rudder deflection can result in potentially dangerous. .loads on the vertical stabilizer, even at speeds below the design. .maneuvering speed; and (3) explain that, on some aircraft, as speed. .increases, the maximum available rudder deflection can be obtained with. .comparatively light pedal forces and small pedal deflections. The FAA should. .also require revisions to airplane and pilot operating manuals that reflect. .and reinforce this information. In addition, the FAA should ensure that this. .training does not compromise the substance or effectiveness of existing. .training regarding proper rudder use, such as during engine failure shortly. .after takeoff or during strong or gusty crosswind takeoffs or landings.. .(A-02-01). .Carefully review all existing and proposed guidance and training provided to. .pilots of transport-category airplanes concerning special maneuvers intended. .to address unusual or emergency situations and, if necessary, require. .modifications to ensure that flight crews are not trained to use the rudder. .in a way that could result in dangerous combinations of sideslip angle and. .rudder position or other flight parameters.
