I'm just thinking out loud on this so take it for what it's worth.
The flaperon skin is epoxied to the foam ribs. There are a lot of ribs as they
are spaced about four inches apart. The top and bottom of the trailing edges
of the skin are epoxied together at the factory and riveted by the builder.
You can drill the rivets out and pop the trailing edge open and see if it has delaminated
from the ribs. It should be fairly easy to pop the trailing edges
apart. Mine were starting to pop apart on their own before I riveted them when
they were new. You may be able to pry it open enough to peek inside at the
ribs too.
Now if you see that some of the ribs need replacing you would most likely need
to figure out a way to repair them in place as replacing them would require taking
the flaperon apart and starting from scratch with it...I think.
You can tell a lot about the condition by just squeezing the skin with your fingers
along each. You can see and feel where they are fairly easily.
If the drain holes were drilled at the trailing edges at each hinge and they were
stored so that any water would drain out the holes they should be okay I would
think.

| Subject: | 912 installation manuals |
We are installing a never-run 912 UL that was made in 1997.
At the time (1997), Rotax published an installation manual that had
values for torques, probe placement etc.
Last year ( 2009), Rotax published a new installation manual covering
all 912s, including the UL, that showed different values than in the
older install manual.
Specifically:
1. The old manual said exhaust flange nut torque 90-170 inch pounds, the
new manual says 177 inch pounds? Which one to use?
2. The old manual said EGT probe placement is 70 mm from the exhaust
flange, the new manual says 100mm. Which one to use?
Should we go with the latest values, or the values in the manual
published at the time the engine was made?
Hope someone can help, thanks,

I'd like to contact Brett Walmsley, who's email address no longer works.
I have a question about his engine installation.

Has anyone put a 912 into service that was in storage for years before
installation? I'd like to hear what you did to prepare it for running
and if you had any problems with it.
Our 912 UL has been waiting for about 10 years to be installed. It looks
good, but we need to know if there are things we need to do before
running it.
Any ideas would be really appreciated.

| Subject: | Re: Flapperon foam repair |
on closer inspection the foam ribs appear OK but it have become unglued from the
skin. No drain holes or pop rivets in the TE. Can it be re-glued and riveted
?

Yes. It can be re-glued with hysol and riveting is done by the builder as part
of the building of the kitfox.
