Cessna 421 Window Replacement

After many years of operational service on windows, eventually they will need to be replaced due to hazing or cracking. Some are even life limited and have to be replaced at a given number of cycles. On this recent project we are replacing the windshield of a Cessna 421 that is kept with us on a regular basis. What I though to be a simple pull and replace gets more involved. This particular airframe is switching from a DC heated windshield to an AC system. I figured that it would be a simple addition of an inverter. Apparently it involves some new switching and wiring as well. Removal of the windshield was further complicated by the requirement of removing all the avioncs from the aircraft. Stick with us to see this project to the finish.
