Hi gang.
Winter-temps are slowly getting to Norway these days, and I've run into a strange problem: when temps are dropping towards freezing and below, (from approx +5*C) the ailerons are becoming more heavy with lower temps.
Today, it was -5*C so it wasn't far below freezing, but the ailerons where definetely harder to move than the elevator.
They are not "sticky", they are just harder to move.
No problem to move either the ailerons or controlstick, it's just that there's a difference in stickforce when temps are dropping.
It's the same force needed to move the aileron both in the air and on the ground.
I've checked the tightness on the nuts and bolts connecting the ailerons to the wing, and no excess tightness there.
Next step is to disconnect all the linkages from each other and check one by one.
But before I'm starting to remove inspection hatches and cockpit-floors, I'm wondering if any of you have a suggestion as to which part to check first?
It's cold to crawl around on the hangarfloor these days, so it'd be nice to be able to go straight for the faulty part.
So any suggestions anyone?
