912uls 2000 hr TBO

in 912 / 914 Technical Questions 13 years ago
I just talked to two guys who took the Rotax heavy maintenance trainin in October. They both said the Rotax instructor kind of pooh-poohed the advertised 2000 hr TBO. He said 800 hrs or somewhat more if you fly regularly over 100 hrs a year is way more realistic. This is a long ways from the stated 2000 hrs! What's up?

    Hi James,

    Whom ever said that is wrong. I would like to hope someone just mis-quoted them. I have lots of friends well over 1000 hrs. My plane is almost 900 hrs. and I have a couple of friends over 3000 hrs. Think of a Rotax more like a motorcycle engine and not like a Lycoming or Continental and you'll see why it last so much longer than the other two or an air cooled only engine. This is another good reason to follow the maint. manual and do what is needed like 100 hr. inspections or following an SB. Do the right thing by your engine and it will last a long time. Rotax has proven this wrong for many many years so why someone might make a comment like that, who knows.

    I agree with Roger, these engines can go on and on if they are maintained the right way. Some of the best things you can do for your engine is regular oil changes, try not to use Avgas, make sure it is not over propped and keep your gearbox serviced.

    I know people who have 3000 hrs and they don't mess with it, they use it and service it when it needs servicing.

    The early engines had teething problems, but a new engine now should easily see 2000hrs.

    Cheers Mark

    Treat these engines with even the minimum maintenance Rotax recommends and you will easily reach 2000 hrs.

    The training course that supposedly gave the negative comments I referred to at the first of this thread was Rainbow Aviation, Brian Carpenter. Since I heard it second hand from an attendee I don't know exactly what was said, only the impression it left on these particular attendees. As far as I can tell, Rainbow is not an official Rotax factory sponsored school, but is a well respected A&P training outfit.

    Having taken the Rainbow Aviation 120hr LSRM-A course myself, and having sent two of my employees through the same course, not one of us has heard the 800 hr limits for the 912 engines from Brian. Perhaps the comments were in reference to the two-stroke engines. Rainbow Aviation is a Rotax Certified Training School for the Service Specialty, and upon completion of the course, an official Rotax I.D. is issued. Rainbow is very conservative, and always says "do what the manual says". Rainbow Aviation is not a A&P training school, but with sufficent experience and the LSRM-A rating, FAA FSDO's are qualifying their LSRM-A's to test for their A&P licenses.
