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, rocks, tree roots, and other small objects. 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. DART Aerospace Run-on Landing Wearplates are specifically designed for the harsh use of training and run-on landings. The run-on landing wearplates feature 2 full-length stainless steel wear bars with more areas of generously overlaid highly wear resistant tungsten carbide as compared to any other available wearplates. The run-on landing wearplates are constructed of stainless steel and feature 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 wearplates come in 2 pieces, which are individually replaceable, and the wearplates are LH/RH interchangeable, which reduces spares inventory. Run-on landing wearplates are 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 wearplates are installed with a corrosion resistant compound between the skidtube and wearplate (no gaskets or sealant required). The Float Skidtube for the AW119/AW119MKll is a one-piece integrated design that eliminates the need for any float extensions and is pre-drilled for float compatibility. *Comes complete with saddles, 2 full length stainless steel run-on landing wearplates & 2 wearpads. Pre-drilled for DART (Apical) Tri-Bag Floats. Compatible on OEM Crosstubes. Compatible with OEM ground handling wheels.
