Does anyone know where to find these service letters? They are omitted from American Champion site. I am interested in SL 415. I am close to having to do this.

Thank you
Joe


American Champion has designed improved wing front strut attach fittings, part number (P/N) 3-1691 and P/N 3-1692, which, when manufactured according to design specifications, will not contain the surface deformities and scratches found on the existing design fittings. After extensive analysis, these fittings have proven to not have the cracking susceptibility of those currently in service. The following presents service information that American Champion has issued that relates to this issue:
* American Champion Service Letter (SL) 408, dated January 24, 1996, and American Champion SL 409, Revision A, dated April 22, 1996, which specify procedures for accessing and inspecting wing front strut attach fittings, part number (P/N) 3-1632-1 and P/N 3-1632-2; and P/N 3-1646L and 3-1646R, respectively.
* American Champion SL 410, dated May 6, 1996, which includes procedures for installing removable inspection hole covers for the wing front strut attach fittings on Model 8KCAB airplanes that have complied with American Champion SL 408;
* American Champion SL 411, dated May 6, 1996, which includes procedures for installing removable inspection hole covers for the wing front strut attach fittings on Model 8KCAB airplanes that have not complied with American Champion SL 408;
* American Champion SL 412, dated May 6, 1996, which specifies procedures for installing removable inspection hole covers for the wing front strut attach fittings on Models 7ECA, 7GCAA, 7GCBC, and 8GCBC airplanes that have complied with American Champion SL 409;
* American Champion SL 413, dated May 6, 1996, which specifies procedures for installing removable inspection hole covers for wing front strut attach fittings on Models 7ECA, 7GCAA, 7GCBC, and 8GCBC airplanes that have not complied with American Champion SL 409.
* American Champion SL 414, Revision A, dated June 25, 1996, which specifies procedures for replacing the wing front strut attach fittings on Model 8KCAB airplanes with improved wing front strut attach fittings, P/N 3-1691, and also includes procedures for inspecting the wing front strut attach fittings on these airplanes; and
* American Champion SL 415, Revision A, dated June 25, 1996, which specifies procedures for replacing the wing front strut attach fittings on Models 8GCBC, 7ECA, 7GCAA, 7GCBC, and 7KCAB airplanes with improved wing front strut attach fittings, P/N 3-1692, and also includes procedures for inspecting the wing front strut attach fittings on these airplanes.

Sully ,
Thanks a bunch. I didn’t have any success finding them anywhere else. I don’t know how you did it. Another angel gets his wings.!

I see that the inspection is required, but where is it specified this inspection is due at 1,000 hrs. I must have missed that somewhere.
