On Dec 3, 2009 Airglas was issued the STC for the GLH-3000 Hydraulic Wheel Ski. The initial STC applies to the following aircraft:
PA-18, PA-12, Cub Crafters CC-18, and the Dakota Super-18.
Husky, Scout, Maule, and Cessna 170 will be added in the future.
The GLH-3000 uses a composite/carbon-fiber construction and weighs in at just 45 lbs per ski. The total surface area of the ski is 1435 sq in giving it 30% more surface area for a weight increase of only 7 pounds over a straight fiberglass ski for a Supercub.
