well, they are not going to do that, so my reason would be to never lose the info. As far as I am concerned, a note like that should be in every single J-3C-65 out there, unless already approved by Field Approval or STC.

Remember, this is obscure stuff. Without Jim's posting, how would you even know? I bet the O-200 is approved this way, but how would we ever find out? Read every single microfische in okc?

I have made the entry on both my Cubs, even though, unlike others, I would fly a flanged shaft under the Continental letter - no difference. The person who inherits my aircraft might need approved data, and now they have it.

I thought the first flight of the O-200 was in September 1957 (memory - don't hold me to that). If that is indeed the case, there may not be any O-200s mounted on J3s by 337 prior to October 1955.

FAA can't disallow the pre Oct 55 337,s. They were all signed a a representative of the CAA so they are now and will forever be "approved Data".

I think I've done at least one O-200 approval. Still limited to 80hp max continuous though.

True, but that is 90 mph in level flight, so not really much of a limitation.
I didn't explicitly state that in my 337, but I did limit it to 85 hp by instrument panel throttle placard and a taped redline on the tach (2665 rpm).
