Manual Reference: Sec 50 Cabin Heat
Brief Description: Sec 50 Cabin Heat

Several items yesterday and today. 1st I replaced the transponder antenna with a blade type. Ed Hayden convinced me that it would be a better choice . I also installed a doubler inside of the tunnel before installing the new antenna. The next objective was to get the tunnel ready so I can close it up prior to installing the panel. I had a leak in an AN fitting in the right brake line where it exits the tunnel to the seat area. Un fortunately I leaked and ran along the spar and the rins. got some degreaser and paper towels and soap and went to work. But 1st I tightened the fitting, was able to turn 3 more 'faces' on the fittin gusing a modified 9/16" wrench (access is tough!). I pumped the brakes several times and it appears the leak is sealed. I ordered some foam rubber insulation several months ago and I wrapped all of the 3/8" fuel lines in the tunnel to insulate them. I don't know if tunnel heat is really the big problem it was protrayed to be, but This should help keep the fuell cooler enroute to the engine. Then I cut and installed the scat tube to the respective forward and aft cabin vents. I also cut and securred more scat tube for the heat muffs. I need another 3 foot piece from the right muff to the valve and I'll be done with this. I'll pick some up tomorrow. Last thing accomplished today was I painted the inside of the baggage door and several of the aft cabin access panels to match the reest of the interior.

Blade style transponder antenna replaced the monopole

Heat ducts run and tunnel ready for closing

Heat muffs (tee to feed both sides) per John Forsling recommendation
