Pneumatic system check:
1) Turn on aircraft keyswitch.
2) With changeover switch in the ‘Brake’ position, engage brake by depressing brake
button on control stick, confirm pump and brake operation, and that function is
acceptable. Repeat for left stick where fitted, if necessary release brake pressure by
switching the changeover valve from Brake to Flight and back again.
3) Pressurise to maximum (nominal reading 8bar +/-.5bar on instrument panel
pressure gauge) Change to ‘Flight’ – check for 3-8 sec max to release air from brake
system.
4) In ‘Flight’ position check that trim goes on and off in same direction as button (inc
left stick switch if fitted), and is indicated so on the instrument panel pressure gauge.
The pressure gauge should jump rapidly between 6 and 8bar, indicating the 6bar
pressure limit valve is functioning properly.
5) In ‘Flight’ position, stick forward. Depress pre rotator activation button on stick.
Ensure cylinder engages by viewing bendix gear rising in the rotor head, and when
the stick is pulled back it disengages.
6) Stick to front, release pre rotator and confirm that pump stops
7) In ‘Brake’ position, put 3 bar pressure on and ensure pre rotator does not function.
Two bar or more pressure may be needed in the system whilst switching to Brake to
enable the changeover valve to function
8) Press the ‘Interlock release button’ and ensure that pre rotator functions (bendix
moves) with brake engaged.
9) Press roll left, and then roll right trim buttons. Ensure the indicator on the
instrument panel moves in the same direction (to the right with right trim, left with left
trim), and the stick is pulled into the same direction. Centre trim indicator, which must
return the stick to the middle (ie the stick requires a small force to push for roll left or
roll right).
11) Engage rotor brake to maximum pressure, and leave the system pressurised.
Monitor for 1 hour minimum, and overnight if possible, for leaks, and address as
necessary. Turn off the keyswitch before leaving the aircraft.
Instrument panel function test.
NOTE! The aircraft core functions (eg fuel pumps and engine gauges) have a protection
system, such that if the alternator is unable to provide sufficient energy for all aircraft
operations, then non essential functions will shut down! This may mean that when the
aircraft is turned on the available voltage may be too low to allow these functions to work,
so the aircraft may have to be started up first, or charger lead connected. These functions
are; Landing lights, strobes, navigation lights, aux socket, seat-heating
1. Aux socket. Aux socket only works if the keyswitch is on, and is limited to
5amps maximum. Centre is positive, outside negative. Can be checked for
polarity with a standard electrical meter, or for function by plugging in
auxiliary equipment such as a GPS and check for the charging function.
2. Engine gauges. Can only really be checked for normal function by starting
the engine and monitoring the gauge response. If a gauge is suspect, see
the instrument panel section for checks.
3. Fuel gauge. Ensure gauge level indication is comparable to the fuel tank
4. Low fuel warning lamp. Function can be checked by disconnecting the cable
to the sensor. The lamp will come on. Remember to reconnect.
5. Landing lights; turn on and off and check function
6. Navigation and strobe lamps: turn on and off and check function.
