PA-12 Niagara oil cooler

Hello Everyone,
I believe I've read all the threads regarding installation of a Niagara oil cooler on a PA-12 with the 150 hp O-320 A2B STC.
I have one of these aircraft and want to intall this cooler on my airplane. I've spoken with Niagara and Kenmore.

I believe you have to have a field approval for this installation. i did not see any mention of this in the threads.
The Niagara papework is specifically a direct replacement for the various PA-18 and 19 models with this engine.No 337 required.For the PA-20 and PA-22 requires their STC.

I also spoke with Eric at Kenmore. He concurred.

Unless I am missing something it sounds like a field approval is a must?

Does anyone have any previously approved paper work?

Thanks,
David

I believe the STC comes with the cooler when you order it.

I have the cooler and paperwork from Niagara. Unfortunately it's as I stated above.

Should be a simple field approval since the installation is identical to the PA18, 20 and 22. I know "simple" and "field approval" are contradictory terms. 8)

Roger that. I'll keep you posted.
