You may not know how to tie a safety wire, or you may be convinced you can't do it unless you're an A&P mechanic. Legally speaking, you're on solid ground: The current FAR Part 43 (Appendix A) specifically allows pilots to replace defective safety-wire without apparent limitation (although we urge you not to touch turnbuckles or control-system items without supervision). But you can't just start wiring. The rules say you have to use practices acceptable to the Administrator: The rule is FAR 43.13(a); and the practices are outlined in AC 43.13-1B.

Section Seven of AC 43.13-1B (Safetying) covers all the aspects of general safety wiring practices, including several diagrams of more and more elaborate safety wiring applications. Section Eight (Control Cables and Turnbuckles) contains extensive additional safety wiring practices dedicated to turnbuckles.

AC 43.13-1B provides a wealth of data in so many fields of aviation that it should be considered a "must-have" book for anyone contemplating maintenance at any level. The price from the government is out of sight (unless you download all the PDF files here), but from commercial vendors like Aircraft Spruce & Specialty it's only $18.95 plus shipping.

Aircraft Spruce & Specialty's catalog has a number of other excellent aviation books, as well as information on just about any other area of interest to aircraft owners, including conversion tables. The catalog is free to U.S. residents, and you can order it online. It also is a must-have reference item for any owner/operator.

For most safety wiring you will need a specialized set of pliers and a spool of 0.32-inch stainless-steel safety wire. Fortunately, pliers are not expensive for the more basic models, in the neighborhood of $23. For the automatic, return-type models, plan on a better quality Milbar brand for $52.

For most owner needs the nine-inch model is fine, with six-inch and other specialized models also available for especially hard-to-reach spots. Aircraft Spruce and Specialty has a substantial pliers and wire selection in their catalog -- and at very competitive prices, I might add.The news come from http://www.bossgoo.com/
