SPAR CONVERSION KITS
Are your wing spars made of wood and do they have cracks, heading for failure?
In 1989 Milman Engineering was approched with a request to become the exclusive manufacturer of spar series 7 replacement conversion kits. Through engineering analysis these spars prove to be 73% stronger than wood spars. Several in flight structral failures have been attributed to cracks in the wood spars. We feel, and our coustomers agree, that aluminum spars virtually eliminate the risk of undetected spar cracks.
Our kit comes complete with STC papers, installation instructions, two front and two rear spars predrilled from our master fixture. Including all necessary spacers, drill jig and screws for attaching rib flanges. For an additional fee we offer all aluminum pieces alodined and primed with PPG Ditzler DP-40.
We also offer an optional fully captured leading edge kit, which fastens around the nose of the rib to the back of the main spar at the top and bottom, and is secured by screws.
Our conversion kits are for 7AC through 7GCBC spars.
Before they fail and cause in flight structural failure call for a complete list of prices and avaliablity on our aluminum spar replacements.
