AD Note

[Sal]

Can somebody explain to me about the AD note pertaining to the spark plug insert on the A-65-8 cylinder.

I'm surprised that with all the Tcraft experts out there nobody has responded to my question about the AD note....sAL

Re: AD Note

A recent check of the AD Notes on faa.gov did not find any listing of any new Teledyne Continental AD Notes on the spark plug inserts. Do you have more info?

Hi Mikeg;
I took a cylinder to a cylinder repair styation in Opa Locka airport to have it re-done. The mechanic told me that he couldn't sign it off because there was an AD note on the cylinder spark plug inserts. I had 2 extra clyinders at home that I bought a few years ago for another engine so i inspected them and sure enough there were no inserts in them. Apparently those cylinders
with the inserts are no longer legal. This is not my saying but the mechanics saying. ..Sal

Re: AD Note

Sal,
I think the old cylinders are still usable. I haven't seen any information that removes them from service.
Most of the C series engines had them originally. The only thing you can buy now have the heli-coil thread inserts. But all of the new cylinders are interchangeable, providing you set them up for the engine application.
If you could find some more information about this condition I would be curious to know about it.

I think your mechanic is full of crap. the only ad listed is on cylinders is on the rocker arm bosses to check for cracks, but does not make them illegal to use. All A series cylinders have spark plug inserts EXCEPT for the SUPERIOR cylinders that can only be used in sets since they have O200 heads on them. Double check the others cylinders you have and make sure you do not have O200 cylinders

Hi Sal,

I think that you got little response because this is posted in the buy & sell section. I nearly never look in here. The daily discussion section probably gets more attention.
