sorry wiley
I don't buy the misset rudder trim
I have more than 17k hours in 737, I ve never seen this happen
I don't doubt you... if you say so. But I have a few thousand in the 737 also and remember the old rudder trim and the indicator on the -300/-400. I also know the guy who was in the left seat and some of the guys on the investigation. The rudder trim WAS full scale deflected on the LGA crash. And the round knob on the rudder trim replaced the old one with the rectangle.
read the probable cause of the LGA crash here...
ASN Aircraft accident Boeing 737-401 N416US New York-La Guardia Airport, NY (LGA)
Mis-set rudder trim may not have played a part in this DIA crash but I am familiar with the LGA accident..
