The flaps on my plane are connected by way of a hole through the flap tube on each side, allowing a bolt to go through matching holes in the flap-control-arm.
On one side, this hole has become oblong, allowing that flap to move a bit independently of the other one.... These parts are aluminum as best I can tell, and in somewhat close-quarters to wood, glass & foam, so getting them welded is not going to be a viable solution.... I'm assuming 'a hole through the control arm & tube, with an AN bolt through that' is the normal way to do this.... Or is there a bearing-type configuration, or some other common way to deal with wobbling flaps due to wallowed-out holes?
