There are numerous references to factory documents that are not part of the drawing set. The most common one seems to be PR-100 and it has information on rigging, fairing tolerences, finishes, bolt torques, riveting, etc. The PPS documents seem to be more specific in the info they provide. I have never seen any of these documents but I am very curious about what they contain. Has anyone here read these documents or, better yet, have copies of any of the documents referenced in the Aviat S-1S drawings?
