    Annual and Lycoming ECI AD

    Greetings All,

    Well, it is time for the annual on Sport MB-901 as well, and it looks
    like there is a possibility of being affected by this ECI cylinder AD.
    I have not been able to verify the "casting part/serial numbers" as
    yet, but the cylinder assy part numbers, and time frame they were
    installed (10/2000), seem to correlate. I am hoping they are not, of
    course, but planning for the worst. I have some questions for the
    group on how I should proceed, and wondering if anyone else has fallen
    into this AD.

    Here is a little history:
    Engine was O/H by G&N around October 00. ECi cylinders (AEL65102) were
    installed. The plane was then partnered out in 1/5 shares and we (the
    club) flew the plane for about 2 years with no issues with the engine
    (ran beautifully). On our second annual as a club, cylinder number 3
    failed compression. Very strange as I remember flying it up to the IA
    and had no issues with it. This cylinder was returned to G&N and
    replaced under warranty with a yellow tagged Lycoming cylinder. (Never
    did hear why the cylinder failed). So now the plane has 3 ECI's
    (approx 530 hours) and one Lycoming cylinder assy (approx 130 hrs) on
    it.

    If the cylinder casting serial numbers are applicable to this AD, My
    questions for the group are
    1. Should I Go ahead and replace them now (even though I could go
    another year, or two before reaching 800 hrs)? What is the sense of
    urgency here? I now have the plane myself and no longer have 4 others
    to share the $$$ with. I don't want $$$ to be the determining factor,
    but if the change can wait, I could plan the $$ for next year's annual.
    I put about 50 hours or so on it a year so I would not even be close
    to the 800 mark for some time.
    2. Has anybody had to do this yet? Is ECi replacing them? I have gone
    to their website and saw indications of a discount on the new Titan's
    with the returned affected ones. Just wondering if anyone has gone
    through the process yet?
    3. I would be sending back 3 cylinders, If I get the new Titans,
    should I spend the $$ and get the 4th one at the same time. Is there
    any reasons (for or against) having 2 brands on the engine? The plane
    has been running about 2 years with number 3 a Lyc and the rest ECi's.
    Have not had any apparent issues. Any long term effects of this?

    Thanks so much

    Annual and Lycoming ECI AD

    I'd run er as is & assume that FAA knows what they are talking about, in
    regards to ECI jugs good to go to 800 hrs.

    I'd be more concerned about the Lyc jug, but only in regards to 'known'
    history..

    Is it known? (1st, 2nd..run..how many hours on er..) Unknown time is not a
    requirement to use, but knowing would matter to me.

    I'd also try to find out WHY # 3 ECI jug failed, in that it had to be
    replaced. I'd think that there would be a way to find out.
