In researching the TWA 841 roll-over incident, all evidence thus far points to a problem with the rudder. Investigators, however, were following a red herring involving the #7 slat. After all, it was a glaring clue staring them right in the face — a large gaping hole on the right side of the aircraft where the #7 slat used to be. In the video below from the National Geographic channel and the series Mayday, the crashes of United Airlines Flight 585 in Colorado Springs and USAir Flight 427 in Pittsburgh are examined. Also covered is the near roll-over of Eastwind Flight 517. These three incidents all involve rudder hardovers.
Did a rudder hardover cause the TWA 841 upset? I haven’t been able to answer that at this point in my research, and I may never be able to say conclusively that it was a rudder hardover or rudder reversal, but all the clues I’m following are pointing at the rudder. Feel free to add your opinions. I’m open to all input.
