The details of a Europa installation. Instructions I've put together to help install a 3300 engine kit into a Europa.We've ordered the Jabiru 3300 Engine and Firewall-Forward Kit for a Europa classic aircraft.
I've had a lot of requests for information about this engine, so I'll try to include some of what I have garnered from various sources. I have talked to the PFA, the factory, ST aviation, Alan Bowden (first Australian Europa with one) and Bob Harrison (first UK builder with one).
Engine Kit The kit we've ordered includes some of the optional extras, such as the oil cooler (which is not optional in Australia) and the vacuum pump (for our flight instruments). Here is a summary of what the kit contains, a more complete description is also available:
Jabiru 3300 6-cylinder 4-stroke engine with starter & alternator installed. Top and Bottom cowlings for Europa
Classic w. fixings. Europa-specific engine mount and fixing hardware
for the firewall and engine sides. Propeller (wooden 60"x48"
two-blade), 2.5" prop Extension, and fixing
hardware. Spinner and flange (this spinner is
narrower than the original Europa spinner, more in line
with the Jabiru design) and fixing hardware. Hot Air mixer box/Filter box and filter
element, Carby heat muff, scathose, hardware. Oil Cooler kit (which sounds like a
useful addition for Spain!), oil bottle and
fittings/fixings. Battery Box, strap, bracket, cables
& fittings. Fuel hoses and firesleeving,
Throttle/carb heat/choke cables, and so forth. Optional kit with vacuum pump, regulator,
filter, gauge and hoses for vacuum powered instruments. Optional switches and engine instruments
including oil pressure, oil temp, CHT, tacho.Engine These pictures are from the manufacturer's web site, and show the basic engine. It is a six-cylinder, four-stroke, air-cooled, horizontally-opposed, pushrod-actuated, spark-ignition internal combustion engine with most of the components manufactured on CNC machinery. You can see that the engine is very neat and designed with aircraft installation in mind.

The starter is at the top of the back of the engine, but otherwise there is a very little obstructing the pilot's sight line when looking over the nose of the aircraft. The oil dipstick (and crank vent fitting) is near the front on the right-hand side of the block. Every other interface to the aircraft is mounted at the back of the engine - the carburettor, magnetos, fuel pump, vac pump (if used) and alternator.
There is a single pressure-compensating (constant depression) carburettor at the back, which feeds into a small (machined) plenum mounted just below the sump. Tubes then feed each cylinder from there, with intake and exhaust coupling to the lower side of the cylinder heads.
The exhaust collectors are banked, with a single welded assembly collecting exhaust from each side. The tubular expansion exhaust muffler joins the two exhausts, and the outlets are provided, but not fitted.
Installation There are now quite a lot of details available about the installation of this 3300 engine into the Europa. The details I have pulled together here are rather picture intensive, so I've put them on a separate page.
The main series of pictures shows the first Australian and the first UK installation of a 3300 engine. The main headings are:
I I have put it up in pdf format and here it is (139k) - best of luck.
I've also provided the original Word document, if you prefer to download the word 95 version, do that here (91k). If you feel there is something wrong with them, or a better way of doing it, please tell me!
Also note that Jabiru have published helpful details on the Ramair Ducts, Oil Cooler installation, and Throttle cables. This last one doesn't download correctly for me.
