Finding Serial Number for a Aeronca L-3C

[vikingBerserker]

Wurger is spot on. If it has the original engine and it has a serial number, we can use it to cross reference to the Individual Aircraft Record Card to get the aircraft number as well as the MSN.

We do have 2 engines (current one on it is missing parts and the other is a fully assembled one) for this, as well as it's original wooden prop. I sent a email to my professor regard this technique hopefully this will help. as we will be check the engine Monday.

Update:
Hey everyone, good news. Just got the these numbers for the engine currently on the Aeronca.
L12-12-44N (Left Case Half)
L11-29-44N (Right Case Half)

I think I have 1943's IARCs, I'll take a look tonight after work.

 

[vikingBerserker]

Sadly, I do not have the ones needed. Anybody else have 1943's cards?

Here is the one on it, but not sure if they changed it at all or not. Hopefully not.

Unfortunately 41-6645 was not an Aeronca.

I went down the log book alley with the OP. Also provided links to OEM drawings via the Smithsonian. It's a static display aircraft and they are Part 147 students. I could not understand the reticence to jig up and weld a new engine mount under instructor supervision. At my level, we don't weld anymore however, in non-turbine powered GA it's still a viable and needed skill set.

Just in case there was an industry norm, I have read that the early Stinson Voyager series, at least at Model 10 time, had the serial number somehow engraved on the fuselage plate at center on bottom where the landing gear struts bolted together. Is there a similar place on an Aeronca? A long shot, but some place to look.

Here is a breakdown of the production of liaison aircraft for the US Army...No images of the data plate. The serial number was painted on the fuselage side under the windscreen.

There may be a component data plate on a major sub-component (such as a wing or tail-plane) which could point you in the right direction.

Original Aeronca Drawings indicate the data plate was on the baggage compartment sidewall. If anyone is interested the San Diego Air and Space Museum at Gillespie Field is restoring 43-27165. Stop by and visit.
