It's not shown on the hinge cross section but it would seem that a thin countersunk washer bonded (Hysol) to the control surface skins would provide more support for repeated installation and removal of the control surfaces and keep the countersunk holes in the skins from getting elengated/worn. -Ed Sikora >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> LML homepage: http://www.olsusa.com/Users/Mkaye/maillist.html
