Cessna 120-140 Association

Hello All, I am new here and a first time aircraft owner and today found a crack in my aileron hinge on the left inboard side. looking for some options from either replacing it or doing a stop drill. just curious what others have done?

Check out AD47-43-06 and SLN-46, even if they don't specifically apply to your serial number. You can see from the crack that the part is being pulled apart. Stop drilling the crack won't stop that trend. Replacement is the approved repair.

OK thanks now comes the challenge of finding the part.
