Thanks grogmonster.
Pending ‘approval’ of your attachment, I anticipate that it will show that the breakage of one cable in the rudder trim system with simultaneous tension put on another in that system will drive the rudder trim in one direction. I wish others luck in telling us what actually happens to those cables during a crash event.
Even so....
It remains odd that PLM would account for all of the ‘veer left then prang’ incidents, unless:
(1) it’s just the product of random chance (eventually there’ll be a bunch of ‘veer right then prang’ incidents due PLM (or the rudder trim being inadvertently being set, unnoticed, at full right); or
(2) there’s a design characteristic that means PLM usually only results in the left power lever migrating.
Any thoughts on #2?
