All - 

I'm new to This site and completed registration recently. I purchased a Homebuilt RANS S-19 with a Rotax 912ULS back in April.It had just flown off its 40 hours (42.5) when I bought it in FL and flew it back to CO.

I have had one oil change at 75 hours and am going to have another tomorrow as I now have just over 100 hours on the plane. Part of what I want my Certified Rotax A&P at KLMO to do is catch up any ASB or SBs. There is only one ASB or SB listed in Rotax Log as being completed.

My SN - 6780858 was purchased in 2013 but had its maiden run this year on March 20, 2019.

i've entered my Serial Number in this website's section for seeing all applicable documents and bulletins but I have checked most of the ones listed and they do not list my Serial Number as applicable.

Is there a good way to find any that I should have done?

Thanks in Advance for any help.

    'Serial number search' actually  isn't able to catch every permutation, it's always better to search by "Date Range".


    6780858 is a 912ULS  produced 22-Nov-2012, and you should check all the "912 ULS" releases published since then.

    To generate a checklist of all potentially applicable service bulletins, go to the SERVICE BULLETINS link (Under SUPPORT/BULLETINS menu) and then click on the button "By Engine Model".

    Select 'ALL Type 912 ULS Engines" from the 'Engine Model' Dropdown, and tick the checkbox  Select Date Range.

    Fill in the blanks 

    From: 11/2012

    To:      09/2019

    then press the Search button.
