I just received the November 2008 issue of The Aviation Consumer and read the article on deicing. I have a TKS system on a Mooney 262 (a 231 modified firewall forward to 252 specs). From my experience, don’t trust estimates. The original installation cost was estimated at just over $25,000. By the time we were done, it was over $35,000. This kind of price escalation is nothing new to people with experience in aircraft maintenance and upgrades. More important, I was disappointed in what the article failed to disclose about TKS. Your article clearly pointed out the critical deficiencies of Thermawing and pneumatic boots, but failed to state the TKS is ice prevention and is not deice. While most people and even the manufacturer talk about it as a deice system, it will not deice light rime ice nor will it deice clear ice once it has frozen into the pores.
