I noticed when cold turning the ailerons left or right on the ground with the engine not running I can hear the a aileron cable rubbing in the left wing.
It was in the low 30's the other day and rotating the wheel I could hear a cable rubbing on what sounded like the aluminum skin. When temp is up around 40's there is no audible rubbing.
It was my understanding that when cold the cables will be somewhat looser due to the different coefficient of expansion between aluminum and steel. Wings shrink more than cables. Had my mechanic look at it yesterday when it was in the 40's. We opened opened a panel on the aft portion midway out beyond the strut attach point and he said it measured around 22. Said spec was 30 +- 10 which puts it in range. Told him I wanted to take it in the hanger and have him take a good look.
Can anyone shes a little light in whats going on?
Thanks,
Tom
