RV3A spar mod

Hi guys.
Just seeking some history on what the 'A' meant for say a 1986 build time RV3?
I know it's spare related but not much else. Found one advertised as RV3A
Cheers
 
CN-1 Mod

Attached is an explanation of the CN-1 mod, which qualified the early RV-3 as a RV-3A. Somewhere around 1990 a CN-2 mod came out for the main spar and now both are required for aerobatics.

My RV-3 has the much more invasive CN-2 mod, but the CN-1 mod was never accomplished!

I've been able to grab the CN-2 PDF from romeolima.com but it seems to missing the drawings, I don't suppose you might have those handy?
 
Here's what I have for the CN-2 spar mod for the RV-3. Hope this helps.
