    Aft fuselage damage done. Paint looks like a perfect match in the shop. Tomorrow I'll roll it outside and see how good it is. Next will be re-installing the root ribs on the cabin and making a windshield. At that point if the wings were on it could be considered airworthy but I have a few more things to finish, Mainly finishing fiberglassing the left wingtip damage, the front upper cowl and painting those. I also have to replace the seals in the engine, but it is getting there.

    I'm very motivated on this project and am in "don't think too hard., Just do it" mode.


    Got more done today.

    Got a windshield made and installed today

    Got the patches on the horizontal stab painted last night

    Installed the tail surfaces for the final time

    Also started the fabric that closes out the fuselage to the root ribs.

    I also installed the tailwheel and redid the springs because I didn't like how the previous owner did them. Once I paint the root rib closeouts the doors will go back on and it will be essentially fixed except for finishing the cowl repair and the engine stuff. Later tonight I'm going to pop the cylinder head off to make sure it is still standard bore and will order the top end kit for the 582.

    Rolled the fuselage outside to clean the shop and also check the paint match in sunlight. Came out very close. Just about perfect. About another week of work and this one will be back in the air.

    Because your ADS-B "out" is using your mode C altitude encoder, and not GPS? The question mark is because I'm only making a partially educated guess. I installed Stratus ESGi transponders in two different planes to meet the Jan 2020 deadline. I remember being surprised that they still needed an altitude encoder, and also that encoders weren't just built into every transponder since the 1980s.

    As an end user of those transponders I can recall that they display pressure altitude if you want (and I did).

    Wrong. ADS-B out transmits both pressure altitude from your encoder AND GPS altitude. https://www.faa.gov/nextgen/equipads...urces/faq/#q36

    Also, encoders aren't built in because some might want to use an encoding altimeter or the altitude source from their EFIS. Both can provide the altitude required for mode C and it will math the altimeter unless something goes wrong.

    John I am very much enjoying your work on this rebuild. Very nice work. What kind of a seal is that between the windshield and the cowling?

    I'm not really sure exactly as the previous owner installed that seal. A little searching on mcmaster carr and it appears it is an edge type wiper seal. I think it is about 3/4" overall width but will get you a close up picture and a measurement next time I'm out there.

    Getting close. Fuselage is pretty much done. Had to pull the engine and de-carbon the pistons and also split the case to replace the crank seals but I got it back together, back on the airplane and fired up that mighty Rotax 582 today. New flaperons coming this week. Once those are on it is ready to go.

    Got the wings back on. I'm now just waiting for new carb jets and I should be ready to get it to the airport for its first flight in many years.
