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. Comes standard with full-length tungsten carbide welded wearplates. Also now available with heavier duty run-on landing wearplates that feature 2 full-length stainless steel wear bars with more areas of generously overlaid highly wear resistant tungsten carbide compared to any other available wearplates.
*Comes with full length stainless steel wearplates & wearpads & blade. Predrilled for compatibility with Air Cruisers and DART (Apical) Tri-Bag (FAA STC SR00831 [AS350 & AS355]) Floats. Compatible with DART and OEM Crosstubes.
