Well, here is my first of what may be many posts asking for a little help. I found this issue yesterday on my 170A where the cabin heat flange where the scat tube attached was corroded and damaged. We don't need cabin heat yet with our 90 degree days
Is the easiest repair to replace the whole piece that is riveted to the firewall, or can you cut off the damaged portion and rivet on a new flange to the current piece? Any suggestions on where to get a replacement part?
Thanks,
Doug
I'm not sure why the picture is upside down...

Re: Cabin Heat Flange Repair
Doug,
Welcome to the forum!
I think the easiest and cheapest repair would be remove the corroded end and attach a 2” flange from Aircraft Spruce. They also sell a 2” flange designed for the Aeronca. Alternatively, I have the whole valve assembly you’re welcome to buy.

Re: Cabin Heat Flange Repair
Doug, Gary has made a good suggestion for your repair. Your own will also work.
The A-model is not known for great cabin heat tho’. Since you’re waaay up NAWTH! ... you might want to look into wearing warm clothes as that heater is mostly famous for warming your left foot. (The later ‘53 models introduced much better cabin heat/ventilation and Richard Pulley (hilltop170) has posted articles here in the forums describing how he converted his A model to B model heat.)

Re: Cabin Heat Flange Repair
I can vouch for the later B-model heater. Even at +5F OAT this past winter, full heat was too much.

Re: Cabin Heat Flange Repair
I finally got around to getting my cabin heat flange repaired. It turned out great and I was thankful for the heat today in NW Illinois.

Getting inside to buck those rivets had to be a challenge. Looks great!

Thanks! We polished the back side of the "foot" on a "L" shaped bucking bar. Took three hands to hold it, but not too bad.
