Hi All,
Flying wires all have to meet tensile strength tests, as per AN requirements. This is what the designers go by. Once the pitts and corrosion have been removed and all the nicks dressed out, have the wires tested for tensile strength. If you need the tensile strength specs, let me know. The wires may have enough strength left in them. Some time ago I bought a TravelAir 4000 with a number of old flying wires dating back to the 30's.. None of them made their tensile test specs.
We also manufacture flying wires and tie rods (and AN665 fittings) down here in New Zealand. see www.vintageaero.com for more info or email me at russward@hotmail.com.
cheers, Russ
