Does anyone have field approval for a J-3 with wood spars and an 0200 engine? Thank you, Julie
Citing the authority spelled out by the Manager, Systems and Flight Test Branch letter dated March 20, 1997 install the 0200, remark the red line on the tach to derate the engine to 90 hp, amend the W&B as required and consider it a minor alteration. He certainly has.
The field approval would be for a J3C65. There is no difference between wood and metal spars. Problem is, you cannot simply use a field approval; you need the original installer or a new field approval.
An existing field-approved 337 can be used to document "accepted data",
whether or not that helps you actually get a new field approval depends on your inspector and/or FSDO.
FWIW I've heard that a field approval dating from before 1956(?) is considered approved data,
and that this can be cited on a 337 which can then be signed off by an IA--
just like an STC.
Does the Univair O-200 STC apply to the PA-11 as well? It wasn't explicit, I know they share the same TCDS, but not all things are the same between them. Anyway I'm looking at a PA-11 project, but sure would like to have a starter; don't need the rest of the electrical system though (generator, lights, etc.)
You are correct in that pre October’56 or’57 (I need to double check the date) is approved data and can be used to modify additional aircraft of the same make and model providing you do it the same way.
I have a note here that it's a 337 prior to 10/1/55. I found several Taylorcrafts that had engine and gross weight changes post WWII that were later covered by STC's.

I have to respectfully disagree with you on this statement. I have never seen an 0200 that puts out what a correctly done 85 stroker does. The stroker puts out 10% to 15% more power. I have seen very few 0200s that will run with a good C90!Who would want to put an o-200 engine on a J-3 anyways, save the hassle, sell the 0-200 and slap on a C-85 stroker with just a logbook entry, lighter weight and puts out almost as much power.
