Just received the new AD for Superior cylinders. For those a little more knowledgeable than I:

1. I am assuming that SL32006W-A2 is not the same a SL32006W-A21P or SL32006W-A20P.

My right engine had the part numbers in the log book.

My left engine just says "Superior Milenium"

2. I also assume that none of the affected cylinders would be designated "milenium".

Or should I tear off the panels and check the numbers?
 
I'd start with a Prayer Bryon. A very long prayer.
 
I thought they were for cylinders manufactured in 2005?? Of course I could be very wrong..

These are different part numbers (PN's), each of which has a group of associated serial numbers, some of both groups which are affected by the AD. edit; I do not see a "SL32006W-A2" listed for sale on Superior's website at all, Bryon - I wonder if someone dropped some numbers on your PN??

I have been surprised so many times that the paperwork did not match the ID tags or engraving on various parts such that unless I installed them myself, I would be physically eyeballing the individual parts to verify the numbers. Regardless of what the logs, the work order, the sales invoice, the 8130, the scribbled notes in the maintenance notes, the guy who put them in says - look at the parts.

I also assume that none of the affected cylinders would be designated "milenium"..

?? I don't think the word Millennium appears anywhere on the cylinder (except the rocker cover).... but I believe the Millennium line is indeed the cylinder affected.

Here is AD 2007 04 19:

Be careful with that. I was hit last year by the ECI cylinder AD. I thought I was in the clear because the rocker panel said Lycoming. But that was only for the rocker cover, I indeed had ECI cylinders.

There is a revision of the AD which adds many more cylinder assemblies.
There are part numbers and serial numbers of affected cylinder assemblies to consider.
The associated service information linked from the airworthiness directive shows you how to inspect for the part and serial numbers which should be stamped on the cylinder.
Verify the numbers by actually looking at the cylinders.

Well, that helps. No way for them to be manufactured in 2005 if they were installed in 2003.

Thanks for the links.

Yes. Thanks. Mine were Millennium installed in mid-2006, and we had to wait for them because of a backlog in production. So also, not from 2005 production.
