Our Patented Bolt-On ski mounting bracket eliminates the need for welding and aligns perfectly with the aircraft's landing gear. Our innovative ski design is a light weight 100% Carbon Fiber structure using the "Monocoque" construction technique. The Monocoque structure supports the structural load by using the skis exterior structure, as opposed to using an internal frame that is then covered with a non-load-bearing outer skin. By constructing a stronger exterior structure; the heavy internal frames and braces are eliminated. Whether it's an aircraft ski or a high performance aircraft, this construction technique combined with using Aerospace/Aircraft composite materials results in an incredibly strong, light weight product.
