Scheduled Maintenance

Thank you very much for the clarification and bringing attention to my lack of revision control.

Edit:  I now see the document you referenced is for the ULS, not iS, engine.  The current iS schedule seems to ask for the maintenance interval in the following field. So, can you please clarify the intended entry for the first blank field?

Sorry, we didn't realize you were talking 912iS!

After looking into this, we found that it is not very clear! We suggest you ignore that section and fill out the checklist in section 05-20-00 Page, 7 OR write up a maintenance release in the log book that covers the information. Essentially, it's duplicate information, and all the maintenance facilities we talked to cross this section out and rely on (issue) maintenance release.

We are going to talk to the Rotax Factory and ask that this section is removed because it makes no sense to duplicate information that a maintenance release covers OR is already filled out in section 05-20-00 Page 7.

Why does it matter? These forms are not official by any means. Its a checklist. The only official log that matters is your aircraft's official engine log, which should contain the proper entries and signatures.

BUTTTTTT,

If you get called on the legal carpet by the FAA or being sued in court having a filled out checklist goes along way in showing your completeness and as they say due diligence. When I did  research project back in 2008 on documentation the FAA and legal experts all agreed. Even writing those 3 liner logbook labels that only says IAW (in accordance with) means you did everything on that checklist and in a legal situation you better be able to prove that because when you write IAW that means you did everything on that checklist and the courts say if you didn't write it you didn't do it. That comes from 30 years of being in court situations and depositions. Since the very first day I became a Rotax and LSA mechanic I have always given a completed Rotax and aircraft fuselage checklist to the customer to put in a binder. It gets filled out and anything I touch, tweak, torque or change gets annotated in the margins. 

The logbook is a legal document, but checklist can be introduced to the FAA and the courts for proof. Plus it helps show trends better, it helps the next owner or mechanic and keeps aircraft value up higher than a guy with poor documentation.

As I always say: Don't strive to be average (way too many of those), strive to be a cut above. It only takes a few minutes longer and it protects you and the owner.

I agree, Roger.  Can you share what you have been inserting in that nebulous blank?
