I figured this is a good one to post here, because many of us ordered engines and built RV14's with engine from the same era.
I had a complete mag failure on my one and only mag in the RV-14. It was first caught on the ground, during run-up, and it wasn't vague at all as to there being a problem. Once I tore into it, what I found was pretty unexpected, yet based on the parts Slick was using at the time, I believe many of you will fun into the issue if you have affected mags, and it is absolutely a good one to take care of. I hadn't caught this Service Bulletin until now, so now that I'm aware I want to make sure you know about it too.
Here's a link to the SB:

I did do a write-up with pics and a video on my site that can show you how bad the issue was after only 305 hours. If you're interested in that, go here:

Check your mag serial number and see if you are affected. From what I understand, the copper based part has been used for quite a number of years. The plastic molding/capturing of the part is a more recent issue. So older mags will probably have the copper part, but may not fail as readily. That said, switching to the new Monel part would make it more bulletproof.
One other side note, the 6-cyl slick mags have always been made from Monel, so those would be better already.
