There was some discussion earlier about deice systems- I'm interested in the Therm-X system myself. I ran across an AD for the Columbia aircraft ( 2006-25-08 ) that mandates rendering the system inoperative effective 12/21/06. This is to prevent a short at the connector that can damage the wings and horizontal stabilizer.
There was no mention of this that I could find on the Kelley website. Even though AD's don't apply to Experimentals, I expect the equipment supplied by RDDent is similar. -Bill Wade
