Quest Aircraft yesterday received approval from the FAA for the Kodiak turboprop single’s ice protection system, meaning the aircraft is now able to fly in known icing conditions. According to the Sandpoint, Idaho-based aircraft manufacturer, the glycol-based TKS system has been installed on three Kodiaks to date. “Since receiving our type certification in 2007, we have continued to work on enhancements and improvements to the Kodiak,” said Quest Aircraft president and CEO Paul Schaller. “Ice protection is an option that many of our customers have been looking forward to having available to them and we are pleased that the system is now certified, especially as we move into the winter flying months.” The CAV Aerospace TKS system “weeps” glycol-based ice protection fluid through precision laser-drilled microscopic holes in titanium leading edges, as well as a dispersion mechanism for propellers. Besides installation as an option on new aircraft, the system can also be retrofitted on any in-service Kodiaks. Quest said the system does not require additional external fittings, such as a cargo pod, and fits directly to the standard airframe. It protects the wing leading edges, vertical tail, horizontal tail, landing gear, struts, propeller and windshield.
