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?
shorter cable run run to the left engine, less internal friction on the cable, than compared to right.
thats was a lot of people in the king air community believe.
