Appendix 2 - Example Maintenance & Inspection Checklist
This is an example of how the best practices described in this guide can be used. The checklist format of Appendix 1 was used to develop a special inspection checklist for the wing structure on certain American Champion airplanes. Results of the records research are shown. Manufacturer service letters, applicable ADs, SAIBs, SDRs, and GA alerts (AC 43-16) are listed. It also lists manufacturer, type club, and FAA contact points along with other related technical references.
