    Hello,

    During my annual inspection, I have found a little play in the ailerons.
    I have checked the bellcranks and rods.
    However, the play is in the inner bellcranck, close to the fuselage and I have no panel to access.
    Between the first two ribs, there is plywood. Is the bellcranck between ribs 1 and 2 or between 2 and 3?
    Do you have any pics?
    Many thanks for your help

    You will find the idler just outboard of rib #1. If you're lucky a gentle tightening of the pivot bolt will cure the play. Don't tighten it too much as you can damage the bearings if there's no spacer bushing between the inner races.

    Thank you Bill.
    It seems that I do not have any hole in the plywood... :(

    No holes? Somebody had small hands and long skinny arms.

    Mine has an inspection/assembly hole. The one in the photo is an S-2C wing but this part of the wing is not different than the A model.

    That's easy to fix, just put the hole where the photo shows and pretend it was always there........
