    1999 ACA 7ECA Citabria “Hamachi”

    The tedious work of rehab on the 4130 steel tubing continues...

    At least there is some visual progress watching the etch prime covering most of the aft section now.

    Ha! Can you imagine how awesome that would be to see Brian chronicle an airplane restoration?

    My photos and write ups aren’t as well thought out. It would be easier if I wasn’t trying to juggle so many as once, but Brian’s forum posting style and mechanical ability to restore stuff is what I aspire to.

    He'd have to retire for sure to have the time to do it!

    I just aspire to getting motivated enough to DO the work, if I can just manage that I am doing well he says with 3 project bikes on the go.....................

    Thanks! I know the bezel is supposed to be black but I kind of like the shiney bit too! Still a ways to go. Need to make two smaller ones and a mag switch. It would be cool if I could find a actual rotary switch i could use for the radio gear. It would have to might small though!

    I've been looking at the pics and a question comes to mind. Is the wood structure just to support the cloth skin or does it also carry some of the flying loads? Or does the metal frame carry all the flying loads?

    The wood just gives the covering shape. It carries some aerodynamic load when the air hits the covering, but the structural loads on the airframe gets its strength from the 4130 steel tubing.

    Some of the experimental STOL planes do away with all the wood and covering on the fuselage to save weight.

    I finished up the new panel for the Citrabria just a few minutes ago. Hope it works for you. Maybe I shouldn't have washed it.......Name:  20190401_143919.jpg

    Beautiful detail on that panel Ken!

    It’s actually nicer than what we had in the Citabria when we picked it up.

    Work continues on the fuselage prep and disassembly.





    Now it’s time to yank the engine off the firewall.

    First drain the oil



    Lay out some tools



    Remove this hose that goes to the cabin



    Fuel line from gascolator to carb



    Now remove the carb heat control cable





    Carb mixture cable next





    Throttle cable







    Silicone is the worst



    Primer line





    Oil temp electrical connection



    Interesting safety wire scheme to keep it in place



    Tachometer cable



    Oil line for the pressure gauge





    Ground and P leads off both magnetos next



    This bundle needs to be separated from the engine mount.





    EGT probe wires



    Disconnect two wires from the alternator



    Two Adel clamps on the sump are removed. They held the alternator and starter wires.



    Disconnect one wire off the starter



    Install the adapter to the prop hub for the engine stand along with a couple AN-6 bolts that are the right length to grip the 1/4” metal of the stand.





    Cherry picker is ready



    Not bad for 45 mins of work

    5 mins later, the airframe and engine are divorced.

    Does the other end of the oil pressure line have a restrictor orifice where it goes into the block?

    Some cars had them to slow the oil loss if the line broke.

    Oh yes, there’s one at the end that goes into the case.

    That’s really important because the line continues through the cabin to the gauge on the panel and will gush oil inside if it ruptures.

    All the pedals and controls have been removed from the fuselage. The instrument panel, firewall, main gear, fuel lines and vents remain.

    We aren’t going to remove the fuel lines and vents, so the next steps will be removing the instrument panel, firewall, and main landing gear.





    I got everything I wanted disassembled off the engine and spend a considerable amount of time cleaning the O-235.

    Engine mount, scat tubing, baffling, etc. removed.



    The baffling is really hammered. I think we will be buying new stuff.

    Definitely will have new scat tubing.

    The engine mount will get sent out to get inspected, painted, and yellow tagged for reuse.

    Here are photos of the engine after a bunch of cleaning which was a PITA. Being a fairly recent remanufacture by Lycoming (2009), it’s in pretty good shape mechanically and cosmetically.

    I will have to check the logs, but I bet the Slick mags are due for overhaul (every 500 hours). Those will be sent out as needed.

    Not applicable for part 91 operations.

    Continental has the same thing but 12 calendar years.

    Our 182D that we just sold had 1100 hours since new...1961! No overhaul on that engine since it came out of the factory and it flies to this day with the new owner.

    It had a top end done in the 1990’s.

    We decided to just repair and repair the baffling instead of buying new.

    Here one of the inter-cylinder baffles being cleaned next to a dirty one. There are a few cracks that need to be stop drilled and some doublers needed on the other pieces of baffling.

    Thanks. My step dad wants to etch prime and paint them. I think we should leave them bare since the paint always chips.

    The really nice ones are Hammertone powdercoat, which stays looking new for years.

    It appears that the head fins are rubbing on them, so any finish would be expected to be damaged by that.

    Yeah, that’s pretty normal. It’s the more visible exposed flat areas that get splatted with bugs at 120 mph which start to degrade cosmetically and look like crap.

    I’m sure he’s gonna want to use his BBQ paint that he loves so much. It actually came out good on the 182D he restored, but it’s just a band aid.

    Or lipstick on a pig...that’s what they say, right?

    A little progress on baffle cleaning and rehab.











    And some glass bead blasting on the fuselage



    Followed up by putting on some etch primer so it won’t rust.



    Still lots to do. The journey continues.

    More baffle business. The rear portion is supposed to be one large piece, not 3. Definitely some work to do there.

    Started putting epoxy compatible with the Poly Fiber process on the fuselage tubing. We chose white.







    Gotta pull the firewall, instrument panel, and main landing gear off next to get the epoxy on everywhere.
