Hello,
I own a 1998 Super Decathlon. When either stick is moved left or right to deflect the ailerons, there is a scratching/scraping sound that is coming from the wing box location (directly above the aft seat). Any idea on what this may be and the fix? Thank you in advance.

Check that nothing is rubbing on the interconnect cable above your head.
Also check that the cables are not rubbing on the left and right side covers at the front of each window.
