To get rudder reversal
In UsAir 427 I was simply stating what is fact after the actuator jammed it stayed like that for a few seconds before releasing, however reversed, so that the rudder controls had switched - So when the aircraft rolled right the captain immediately took control and applied full left aileron and full left rudder it did not respond and continued to roll as it was jammed right, then when it released he was now applying right rudder even though his foot was on the left pedal - This was probably the most tragic part about that accident.
I only brought that up in a response to a point made by MrSnuggles on page 1, has absolutely nothing to do with 587.
