What is the procedure of doing oil analysis in Rotax 914 engines? Can anyone specify the equipment required to perform this analysis? And has Rotax issued any service instruction or bulletin specifying the allowable limit of metal particles and their sizes and corrective actions in case limits are exceeded?

Also if there is any information about allowable concentrations of metals like copper, aluminum, iron, lead, chromium, nickel etc

    The procedure is to order a sample test kit from the Oil Analysis Laboratory of your choice.
    You return a sample of your Oil to the lab and they return the test results to you.
    Most labs keep a data base of similar engines as a reference baseline and also a historical trend of your specific engine.

    A popular laboratory in the US is Blackstone.  
    There will be other labs closer to you.
    Search Google for Oil Testing Labs Pakistan.

    Send the oil sample to the Wearcheck laboratory and state it for a Rotax aircraft engine.

    They will have all the necessary reference information that is specific to the Rotax.

    I've been using AvLabs for 20 years. They have a huge Rotax database. They test each sample 3 times. They compare that sample with other Rotax engines with the approximate same hours. They send me and the owner the test results. If anything is way out of whack they will call you. Many times samples can be ruined by catching it either at the very beginning of the drain or the very end. The bottom end will always have more heavy contaminates and the top of the drain very light contaminates. Both skew your real results. Avlabs test kit is about $20 and comes with a self sticking mailing label. Catch the sample, fill out the form and drop it in the mailbox.

    Example analysis.
