>>>>>>The military is probably the only customer.<<<<<<
On particular aircraft series sold in the USA I am aware of that uses Type
Certified Rotax engines is the Aeromot Ximango motorglider. (pronounced
"she-mongo") The AMT 100 Ximango uses the 80 hp 912, the AMT 200S Super
Ximango uses the 100 hp 912s, and AMT300 Ximango Shark uses the 115 hp
turbo 914. All three airframes are identical except for the engine.
Ximangos are Type Certified in the USA (and 26 other countries), and most
were built with type certified Rotax 9XX engines in them. I was told by the
owner of Aeromot when I visited the factory last year that the only
exceptions were for about 8-10 of the very earliest versions which were
built with the Limbach VW derivative. Aeromot changed to the Rotax early on
after having severe issues with shock cooling on the Limbach. (cracked
heads, cranks and cylinders). To my knowledge there is one Ximango flying
with a Jabiru 3300 engine (IIRC in Australia) and it is one of the earlier
ones that was originally built with the Limbach.

The type certificated Rotax 912 engines are built on the same assembly line as
the UL engines but there are some very minor differences, other than the paper-trail.
The type certificated 912 F3 engine in the Diamond Katana I've been maintaining
for several years has two springs on the throttle arm of the carbs instead of
just one. It also has aircraft aluminum fuel tubing from the distribution block
to the two carbs instead of of flexible hose. The return line to the tank also
has braided SS tubing but this last bit is an airframe specific item that
may be peculiar to the Diamond. The other fuel line from the firewall to the mechanical
pump is regular flexible hose as is the hose from the mechanical pump
to the distribution block. The coolant hoses appear to be identical but the
oil hoses, instead of being standard push-on type are made-up hoses with special
end fittings, also Diamond specific. The Katana also has an airframe specific
air shroud over the top of the cylinders which ducts air directly from the
cowl inlet to the cylinders.
Although the vast majority of the parts are identical, when I order replacement
parts I must specify Certificated to get the required paperwork that keeps the
Diamond legal. Of course Lockwood gets a higher price for these paper-trail
parts.
