Abstract
The FAA is adopting a new Airworthiness Directive (AD) for all Columbia Aircraft Manufacturing (previously The Lancair Company) Models LC41-550FG and LC42-550FG airplanes equipped with Kelly Aerospace Thermal Systems Supplemental Type Certificate (STC) SA02260CH, Thermawing Deice System (also known as E-Vade). This AD requires you to deactivate the deice system and install a placard in clear view of the pilot. This AD results from problems with the installation of the Kelly Aerospace Thermal Systems Thermawing Deice System following STC SA02260CH. We are issuing this AD to prevent a short circuit condition at the deice heater connector, which could result in damage to the wings and horizontal stabilizer. This damage could lead to reduced structural integrity of the airplane.
