“A” Model flat deck

agairmaintenance · Apr 15, 2020

I just bought a PA18A project. Has anyone installed the arched rear deck on an AModel and if so what are the legalities?

DENNY · Apr 15, 2020

Both are on the same type certificate. I have a regular fuselage on a PA18A cub, at best I think logbook says fuselage replaced with new one. HOWEVER!!! It all depends on who is going to sign off the annual!! Very easy to get yourself into a pickle depending on what part of the country and who the IA is. It is not just the little upper baggage stuff that is different, top deck tubes change!! Are you going to do L21 glass?? Where do you live? Have you asked your IA? I would say this would be a great test to see if you are going to have issues down the road with minor vs major modifications.

I didn’t realize that they were both on the same TC. This is my first SC project. I will be the one signing it off. I have considered the L21 glass but haven’t really decided on that yet. I never realized how many different mods/STCs there were to consider. I can see now that there may be as many hours in research as there is actually rebuilding.
Thanks for your input.

But are you going to keep it!!! Send it down the road and it may have problems. I get in contact with Steve pierce if he has the time, One hour on the phone at his shop rate is at least 10-20 times what you pay for it.

This is excellent advice.

Be careful, there are two type certificates. 1A2 and AR-7. I believe that the appropriate one is stamped on the data plate. I do remember working on an AR-7 airplane which had the regular common fuselage. I thought it strange, but chose to ignore that detail. At the time I didn't know whether that was the correct decision or not. A friend owned the airplane, it kept him flying, he later sold it, I never heard from it again. Right or wrong, it is gone now.

We are rebuilding an A model fuselage right now. Installing the Flanagon STC which puts a V structure in the hopper opening and the L21 style glass retaining the flat back rear deck. Here is a thread with some pictures. https://www.supercub.org/forum/showthread.php?45929-PA-18A-parts

Interesting to note that Dakota Cub replacement fuselage is STC’d for the A model but Airframes is not.

There are a number of “A’s” with traditional upper fuselages. The biggest issue you need to resolve paperwork wise is the hopper cover requirement (forget where it is listed, perhaps the flight manual).

Thanks for all the great info. The hopper door was previously removed and a X brace installed in its place but no paperwork. I am going to look at this Flanagan STC.
Thanks!!!

The last one I saw done was on a Field Approval, just referencing the PA-18 drawings. If you want to pull the FAA records, it’s N7067D. It had a restricted certificate, and last fall I issued a standard on it.

Hey Steve make sure you get the Vee in the right direction, saw one rebuild in Montana that had it installed backwards and they didn’t seem to concerned when I mentioned it to them.

Yea, it is hard to tell from the drawing.

I bought my dream plane last September, a 1955 A model... The Flanagan STC is what sold me on the A's... It just looks so unique. All this talk make me want to rebuild sooner rather than later!

md11freighter · Apr 19, 2020

Atlee did the hopper door on my ‘53 A model. If someone wants I’ll try to post the drawings.
I thought he had an STC for it....but there’s so much paperwork on these things I can’t remember.
I do like the way the A models fly.

RaisedByWolves · Apr 19, 2020

Can you post the drawing?

I just bought an 1954 A model and am planning to do the Flanagan STC as well.............good info here.

md11freighter · May 31, 2020

Here's the drawing for my hopper being covered by Atlee.View attachment a model cub paperwork.pdf View attachment hopper cover drawing.pdf

I guess I really am that tech un-savvy. I tried to attach a couple different scans.
If someone wants a copy...PM me your address and I will just mail a copy to you.
