Description
We believe that conventional skidtubes are under-designed for the types of landings most helicopters encounter. Conventional skidtubes are ill-equipped to face the critical loading conditions encountered when landing on uneven ground. Under these conditions, simple round tubes tend to puncture, dent and bend because they cannot maintain their shape. DART Aerospace’s revolutionary patented Round-I-Beam™ technology combines the conventional round tube with the strength of the I-beam made from 6061-T6 aluminum. In DART Aerospace skidtubes, the central I-beam web absorbs most of the impact on landing so the tube maintains its integrity. Even with the addition of a central web, the weight is comparable to that of conventional skidtubes. The Deluxe skidtube comes complete with 1 full-length stainless steel run-on landing wearplate, tow ring, toe step & wedge kit. DART run-on landing wearplate features 1 full-length stainless steel wear bar with more areas of generously overlaid highly wear resistant tungsten carbide as compared to any other available wearplates. The run-on landing wearplate is constructed of stainless steel and features an easy thru-bolt installation that makes installation or replacement quick and easy, eliminates clamps over the skidtube and prevents the wearplate from rotating on the skidtube. The DART Aerospace run-on landing wearplate is LH/RH interchangeable, which reduces spares inventory. The Run-on landing wearplate is installed at the factory, eliminating the need to source from several vendors and the additional costs for separate shipping and on-site installation. The run-on landing wearplate is installed with a corrosion resistant compound between the skidtube and wearplate (no gaskets or sealant required).
*Comes complete with 1 full-length stainless steel run-on landing wearplate, tow ring, toe step, wedge kit & blade. Thru-bolt wearplate installation. Predrilled for compatibility with Aerazur & DART (Apical) Tri-Bag (FAA STC SR00831 [AS350 & AS355]) Floats. Compatible with DART & OEM Crosstubes.
