    Rob's comment should be noted by everyone filing for a warranty claim / repair claim or just an engine issue you want to report.
    The CSIR is used to report engine issues if you are not filing a warranty type claim and you won't get a reply back if just reporting an issue.
    The CSIR is REQUESTED when filing a warranty or repair claim with the US service centers. If it is for a claim then you should get some reply from the service center. Either an acceptance or a denial.
    A warranty or repair claim MUST be filed through the Regional Service center like Lockwood, CPS or Leading Edge if you live in the US. I do believe that after some point in time and you haven't heard anything then call the Service Center back and ask for some sort of reply. I haven't found service centers to be good about long term call backs. I think they tend to get lost in the day to day shuffle. So don't be afraid to put a bug in their ear.


    The CSIR is not tech help as Rob pointed out and you need to contact a service center or Rotax IRC for help.




    Side Note**
    Way too many times the CSIR is only half filled out and does neither party any good and will usually be cause for denial of a claim. Fill in all blanks or write not applicable (N/A). If you file a warranty claim or claim for repair help make sure you send in your logbook entries and the reason and or documentation for the claim being reported.
    If you are a person that thinks the 3 line annual inspection logbook entries are good or rarely log anything then you may run into problems. Many times rag-tag logbook entries get equated with the same type engine care. Good logbook documentation is a must for any type of warranty or repair issues not to mention any legal problems with the FAA, insurance companies or court action. The logbook for the most part is the sole document that shows anyone that has never met you what was done or how that engine was cared for. This is how you are judged whether you like it or not.
    As one of the past blog articles title states "Documentation is Everything."

    Jonathan:

    The serial number of my engine is 5646338, and the serial number of my crankcase is 27347. Lockwood Aviation has been very helpful, but told me that they have been informed by Rotax that this issue will not be covered by any warranty. They are however, going to submit a request for some "goodwill warranty" on my behalf.

    I agree that the engine will not be worth much money with the fretted crankcase, but still was interested if anyone has any insight on what engines with this type of issue are worth. Since I haven't got any response to my question with a dollar value, perhaps most people just repair engines with this problem vs replacing them. A repair was going to be approximately $10,000 US, and an overhaul about $14,000 US. A new engine is $17,600 US, so I elected to replace the engine.

    It is disappointing that the engine did not make it to the 1500 hour TBO. It has been maintained meticulously, following every single Rotax requirement to the letter. The fretting issue did not cause any issues with engine performance, and only showed up due to high aluminum in the engine oil analysis. Besides a short-lived minor problem with vibration, the engine ran very well.

    To address Roger's comment about logbook entries, my entries were always extremely detailed and accurate. I do agree with his comment about the importance of logbook entries.

    I'll be sure to post my final results when things are concluded. I should have my new engine installed by the end of next week, but don't know when I will get a final decision from Rotax.

    Hi all

    My engine s/n 5644188 with 800 hours, has also succumb to the dreaded fretted crankcase. I stripped the engine for a crack between cylinders 1 and 3 and discovered the fretting, I wonder if this is related. I am replacing the crankcase with the new style case.

    The fretted case issue seemed to be around 2004 - 2006.
