I am not aware of anyone who has actually had the AMOC completed posting information regarding their success/satisfaction etc. It appears that all Group B cylinders are now being replaced with new ones, regardless of whether the aircraft is experimental or not - see Amy Laboda's article in Kitplanes a month or two back on this issue.
I am unwilling to have the AMOC completed on my Group A cylinders when FAA has not approved it. What would I do if the FAA decides to disallow it? For now, I will live with 50 hr inspections. It doesnt take long, and the cowl is off anyway at one time or another over that interval. Others have idnicated they are not comfortable with this and are just sucking it up and purchasing new, but discounted cylinders. Pick your poison.

The issue is the P/N is not AEL65102 and therefore not officially part of the AD, tho it has a cylinder serial number is in the "B" range, it is a titan EXP tapered fin cylinder.
I believe from the Kitplanes article and the AD dated 2009-12-26 that any P/N AEL65102 cylinder whether installed on a certified or experiemental engines are covered by the AD.
Was wondering if there is any feeling on a NON AEL65102 otherwise in range of the AD.
Feels like i'm in limbo.

Since the EXP cylinders are experimental, would the FAA even issue an AD? I would hope they would...

I hope they don't because if they do, then they will start issuing AD's on all Experimental aircraft and that could be a real mixed bag, mostly bad. JMHO

Group A vs Group B
Does anyone out there know what the difference is between the Group A cylinders & Group B?
Why is there going to be AMOC to fix the Group A's but not the Group B's, which have to be removed & never repaired per the AD.

Well, it's been a couple of years since this thread about the bad ECi cylinders was started.
For myself, I had four 'B' cylinders that I returned to ECi to be "reworked". However, I'm not flying yet...but close.
Anyone have any performance reports that they would want to share regarding the ECi Group A /B cylinders?

Well this has nothing to do with the subject of the AD (cylinder heads leaking/popping off the barrel), but with 1450 hours on my Group A's, I have pulled them off for increasing oil consumption, and am going to replace the jugs becasue it is the simplest option.
Way back many years ago, when you'd have a bad cylinder (for any reason), you got it repaired. Cylinders were routinely overhauled, cracks welded, etc. Now the new prices are low enough (about a Grand per jug, "loaded"),that it's sort of like "why fool around"....put a new stud on and fly in peace.

No problems with my group As to date; I plan on flying with them until there is a good reason not to. If anyone has any documentation that there are more failures in Group A than cylinders that are completely outside of the AD, I would like to hear about it
I don't believe the AMOC for Group B was ever approved by the FAA.
