    Lycomming io-233 or o-233 issues

    Are these engines any good? What issues have they had and have they been resolved? My search on the web has not returned much information.

    Thanks,
    Forrest

    I am told by a flight school operator that the electronic ignition last 100 hrs and then has to go back to Champion for repair consistantly.

    I don't have any experience with this engine. However, based on what Steve said I would wait until the bugs were worked out before committing to using one. Having to send the ignition back every 100 hours is basically limiting you to the home traffic pattern, to say nothing of the inconvenience.

    I am a fan of electronic ignition. It must be totally reliable to be useful. 100 hours is not reliable.

    Further to Steve’s input, I concur the Ignition is unique to this model engine and problematic! .... so unable to change out to something with proven reliability...

    If it is experimental you could install mags or what ever. The one I exampled is an SLSA used in a flight school and Lycoming maintains the ASTM standard and they would have to approve the change if SLSA is retained.

    This engine has been out for several years. Not having the issue resolved by now doesn't look good on lycoming or champion. In my business there would be Managers and Engineers fired for this. I wonder how they are keeping it under the radar? You would think that one would be able to find more information on the web about the proplem.

    Appears to me that anybody that bought this engine has a plane that has the value of one needing a new engine unless they sell it to an uninspecting sole.

    Thanks,
    I'll stay away.

    Regards,
    Forrest

    I have the 233 in my S-7 and have about 275 trouble free hours on it. I chose that engine because Lycoming called me and asked if I would make exhaust systems for it. During the building time they sent me at least 3 new ignition systems and the engine hadn’t been started yet. I really didn’t want to be a tester for Champion so I installed a dual lightspeed setup. It’s been trouble free and a proven system.

    Well, Champion managed to keep their spark plug problems "under the radar" for over 10 years until enough of the aviation forums "outed" them that they were forced to fix the issues... I suspect there just aren't enough airplanes using this engine to have achieved "critical bad PR mass" to raise the attention of Champion management.

    Frankly, at this point, they've sullied their corporate reputation to the point I just avoid anything the company manufactures... It's one of the reasons I now fly a Rotax-powered airplane – it's just not easy to avoid Champion products if you fly Lycoming or Continental engines...

    So what are you planning on putting this engine in?

    “If it is experimental you could install mags or what ever. The one I exampled is an SLSA used in a flight school and Lycoming maintains the ASTM standard and they would have to approve the change if SLSA is retained.”

    Thanks Steve, that is a much better way of explaining it. I was referring to LSA category.

    Experimental. Salon, wanted to know if one should stay away from an slsa with this engine.

    Thanks for the replies!

    Are you going to instruct in it? If not no reason not to convert to ELSA

    We have yo-233 in our Super Legend-first failure at 180hr, replacement from Champion, which we waited for several months to receive, failed 35hr later. 2 mags is not an option as the accessory case only has one hole. Champion comped us a Slick mag (Champion again), added a single Lightspeed. Only about 10 hours on this setup. Working ok so far. Needless to say, this has been very frustrating. Champion management knows ALL about the situation.
