I used Bob Andrews (the Fabric Doctor) aileron and flap hinge bushings on Cathy's Tri-Pacer. Works great. You drill and ream with tools included and insert a stainless steel flanged bushing which should wear a lot better than the aluminum in the hinge blocks and the steel in the aileron and flaps. Here is a web album of pictures showing the STC'd kit and how to install the bushings which are approved on the hinges on the ailerons and flaps and the hinges coming out of the wings.

Piper Aileron/Flap Hinge Bushing Repair Kit STC SA02128LA
This is an STC'd/PMA'd repair kit for worn aileron and flap hinges on just about all the fabric Pipers, shortwings
included. This has been a chronic problem in the past and although any modification or repair to the hinge is
considered a major repair by the FAA, there has never been any approved data to accomplish such. The repair
consists of reaming the hinge slightly oversize to accommodate a bushing. An epoxy adhesive is also used to
insure stability of the bushings. The kit includes Installation instructions, STC approval, Instructions for Continued
Airworthiness, a custom reamer, two part epoxy adhesive, a mixing pad and utensil, 2 new clevis pins and 4
bushings to repair two hinges. Additional bushings are available separately @ $4.00 per bushing if needed. Price
is $139 post paid. Please contact Bob Andrews at 909-621-2859 or

information.
