Has anybody found an Ercoupe donor fuselage for the Chum project. I've got some landing gear and an engine. The wings shouldn't be too hard to find.

I believe I would have to be the test pilot since I don't know many others with more current Aeronca Tri-gear experience. :lol:

Why don't we do the flight test together. I have time in a 7HC. Could do the load test and flight test at the same time! David J./Jasper, GA

Funny I should run across these Chum postings today because about an hour ago I saw a short article about it in one of my ancient aviation magazines.

I didn't remember that it ever existed.

The same mag has an article showing a single seater made by Schweizer using most of the airframe of their popular single place 1-26 glider and powered by an A-65. It is actually a neat looking plane and is called the 1-30.

I noticed the Aeronca Chum threads on the fAA site. Grumps asked about Ercoupe dwg's, they are out there on the Ercoupe website's. "www.ercoupe.info/"

Todd Trainor said that the Chicago FSDO office has loads of Chum and the glider Aeronca made there but as he did not have permission from the type holder they would not let him make copies.

Any idea who holds the type for these? Aeronca still?

Joe,

If Wikipedia is correct there never was a type certificate given the N-numbers that were used, NX39637 and NX83772. Also, I couldn't find any TC # in Juptner's. What if the NAA president got supporting letters from Aeronca, Inc, the Ercoupe club and the EAA to go with NAA's appeal as encouragement for ACA to release the documents to the NAA?

Carl,

That would be what I would do. Lets see if we can get some of the other people interested.

Hey Joe,

Do you mean a jointly signed letter by the NAA and others who would support the idea?

Would feel that it would have to be from Aeronca, then the NAA and so on. Who knows what the Feds would want but as Aeronca made the plane that should suffice to allow the NAA to get copies of the blueprints. We could then scan them at the Aeronca factory on their commercial scanners and be good to go.

There is no type certificate. You guys get the prints--I've got the N number for 83772 and some sheet metal folks. Get someone to donate an Ercoupe and it could be reverse engineered with the prints.

I have a spare C85 laying around. There must be somebody that has access to an Ercoupe.

Univair holds the type certificate.

Aeronca licensed with ERCO to produce the 415.

ERCO is still a functioning company today. They probably have the history of the aircraft (Aeronca-ERCO license) in their archives!

I am going to Connecticut next week where ERCO is located, I will be glad to ask them about the history of the license with Aeronca.

Before anyone spends too much time and money tracking this down, I'll try to set the record straight.

I am in an odd position because at one time I owned the data plates for the prototype Chum. So technically speaking, I am a former 12-AC Chum Owner. I donated the data plates to the NAA two years ago, at the Middletown Fly-in.

The Chum shares no parts with the Ercoupe, other than maybe the landing gear and the fact that it is a low wing made out of aluminum. The NAA has all of the original Chum Drawings. I probably have 100+ hours reviewing them. OK, maybe a little more, I don't have much of a life. At one time, Mr Dart out of New York state was going to sell the drawings as an experimental aircraft. But, it is not as simple as an RV. So there was only a little developement completed on making the plans more user friendly.

If there is anyone that is really serious about trying to re-create a Chum, please contact me. If you have extensive background with tin and complex curves that would be great. I've made a few molds to have some rudder horns cast. But, I need to get a couple more projects done before I really wade into this.

Jim Thompson, along with a bunch of us out here would someday like to see one fly... From the left seat!!!!

Since my goal is to have one of every AERRONCA built, I need to do this as part of my Bucket List. My agreement with Jim Thompson is that when I show up with the plane, I get the data plates back and he gets to go fly it!!!!

PS. Happy Birthday to all of my fellow Marines out there!!!

I wasn't thinking of scratch building the final version of the Chum. I was thinking of using an Ercoupe and replicating the first one 39637. Do some cabin area rework a new cowl and put an oleo on the gear. It would never be an Aeronca but the chances of finding the real ones are slim. Unless, .... some of you old timers are holding out on us.
