Years ago there was a problem with inadvertent activation of the rudder trim on 737s because of the switch design. The knob was then changed from the wafer type to a round dial type. After 9/11 most cockpit door entry systems were redesigned and different operators adopted different designs. I am not familiar with ANA's, but I doubt it looks like the rudder trim. It's hard to believe it was a case of which switch was which. Sorry.<br /><br />I believe additional details will surface that will reveal an operator vs design problem. More information, however, is needed to adequately answer the "what, how and why" of this incident.<br /><br />Good article as always!<br /><br />JimJim Blaszczakhttps://www.blogger.com/profile/00096277595889819199noreply@blogger.com
