I have a lot of avionics service manuals and I am willing to trade schematics diagrams, or some pages, from the manuals for other schematics diagrams from other service manuals that I do not have and probably will need in the future. If you or your avionics tech are looking for a schematic diagram to fix a radio or other avionics on your aircraft you may wish to contact me. I may have exactly what you are looking for. Thank you
