26.6 Powerplant
26.6.1 Fuel tank calibration
a) Put a small quantity of fuel into the tanks.
b) Drain the fuel through the fuel pickup connection.
Any remaining fuel is roughly the unusable fuel, although it will be
affected slightly by the flying attitude.
c) Add measured quantities of fuel into the tanks, marking the side of the tanks at
5 litre intervals, starting from zero at the unusable fuel level.
Allow time for the tank levels to balance before marking each level. This
can take a few minutes.
26.6.2 Propeller pitch
Assemble and fit the propeller following the instructions supplied with the propeller.
Set the propeller pitch to that specified in the HADS for your propeller.
Note that some installations are defined on a max static RPM (5000RPM for
912 and 4850 RPM for 912S installations using the Kiev prop 273 and 283
respectively). This means that once the engine has had its initial run up the
propeller pitch may have to be finely adjusted to accurately achieve this. If the RPM
is a long way out when the prop is set on its recommended starting pitch, then the
RPM guage may not be indicating accurately and may need calibrating with an
optical tachometer (your inspector or local engine service facility should have one).
26.6.3 Engine run-up
Read the engine manual for procedures relating to the first operation of the engine,
and subsequent running-in. Follow all requirements for engine and gearbox oil,
coolant mix etc. .
It may be advisable to tie the aircraft to a solid structure before any engine power
tests, rather than relying on the brakes, particularly on wet grass.
Carburettor balancing on the Rotax engines may be set approximately by comparing
the movements of the throttle levers on the carburettors, however for best results the
balance should be set by a Rotax engineer familiar with vacuum-gauge balancing.
The Engine Installation Checklist will have to be completed with the assistance of
your Inspector.
26.6.4 Throttle Friction
This is adjusted using the two nuts at the port end of the throttle lever torque tube.
Set enough friction by tightening the inboard nut to prevent the throttles from
vibrating open or closed, then lock this setting with the second nut. Do not set any
friction at all on the starboard end of the torque tube.
