| Subject: | Spark Plug Replacement on 912 UL Engine |
I am a little confused on the above subject. The Rotax Line Maintenance
Manual Check List, Section 05-20, page 11, sub-section 2.2.13 Spark Plugs,
b) Replacing Spark Plugs shows a foot note 1 at the 100 hour interval (or
annually), which ever comes first. The foot note simply states only
applicable for engine types 912S/ULS/ULSFR. I am confused about these
designations as they would or would not apply to a 912UL. I have a 912UL and
need to know if I am to replace the plugs at 100 hrs (or annually which ever
comes first). What is the replacement interval for a 912UL?

Roger/Paul:
Sorry, I hit a send button by mistake before finishing my message. Here is
the finished one.
My Allegro 2000 is an E-LSA so I don't have your paperwork and approval
problem. However, based on how my Allegro is performing I have not yet
decided that I need the VGs. I do know that they improve performance at the
lower speeds, but how much? The Allegro is such a slick plane and it glides
so well, I'm not sure I would put the VGs on. The choice would seem to me to
be a personal one rather than a "major change in performance". I may be
wrong, and am open to the opinion of others.
In my opinion, based on my experience over the past 3 years with Fantasy Air
Czech Republic), as well as the US Distributor, you will have a very
difficult time getting them to do the testing and paperwork to satisfy the
FAA. In fact I personally would not waste my time! I would rather spend it
flying and enjoying life.

Hi Roger
Interesting. I imagined getting a mod approved would be a difficult process.
In the case of the VGs, I would think Fantasy Air would want their test
pilot to do test flights.
The factory does not have the best reputation for responding to customers
and I doubt they would make the effort to test the VGs.
If Hugh or anyone else is seriously interested, maybe we could get the
factory interested.
When I was in Czech in 2005, I offered to pick up the tab for fuel if they
paid their test pilot for a series of test flights.
Regards
Paul

Hi Hugh,
The manual does state 100 hrs., but in the Rotax classes they would like to see
them changed at 75 hrs. For the price of your hide, the plane and your engine's
health that's cheap. I change all the planes I work on at 75 hrs. and oil at
50 hrs. if no 100LL. If they use mostly 100LL I change it at 25 hrs. If you
change plugs at 75 hrs. that's only about $.30-$.40 cents per hour for all 8
plugs.

Hi Hugh,
My mistake. I thought your Allegro was SLSA. You are right that you can do anything
you want and anybody can work on it.
For the SLSA bunch that needs the approval letter, you do not need them to do any
testing. You sign off on the letter that it still falls within SLSA standards.
There's a special little statement at the bottom of the document that keeps
you honest and it puts any issues in your court not the MFG's. I have 6 of those
letters.
The letter has your name, plane ID serial number , N number, the reason for the
work, what you did, what parts you used and some pictures. Then the statement
at the bottom that the mods will not put you out of the SLSA category. You sign
it and the US Mfg stamps it.
