3.4.8. Fuel System Malfunctions
The fuel system has been designed to be as simple to operate as possible. The sump tank
should remain FULL at all times. Should this not be the case then transfer of fuel from the main
fuel tanks has ceased. This situation will be indicated initially by the red “FUEL” warning light
located between the fuel gauges illuminating, indicating that the fuel level in the sump tank has
fallen below its usual operating level. Conrmation of this results in the illumination of the red
LED “SUMP TANK LOW FUEL” warning light showing that the fuel level is continuing to fall.
The fuel warning system is provided with two red warning lights each operating from separate
power supplies to provide a measure of redundancy in the event of a fuel warning system
failure.
The only two likely causes of this problem are:
The fuel supply from the main tanks has been exhausted - This condition will also be
indicated by the fuel contents indicator gauges and the illumination of the amber “CHECK
FUEL” caution lights adjacent to each of those, providing a progressive series of warnings prior
to the illumination of the red lights.
ACTION: Prepare immediately for a precautionary/forced landing as all useable fuel has been
consumed and limited fuel remains in the aircraft from when the rst red warning light illuminates.
Both the fuel lters have become partially or completely blocked - This event would be
signied by illumination of the red “FUEL” and “SUMP TANK LOW FUEL” warning light(s) whilst
the fuel gauges and unlit amber “CHECK FUEL” caution lights indicate that useable fuel remains
in the main tanks and supply lines.
ACTION: Reduce power and immediately prepare for a forced landing. Sufcient fuel
may still be available in the collector tank for 5 to 10 minutes of engine operation,
depending on power setting. Reduce power to conserve available fuel.
3.4.9. Spins
Intentional spins are prohibited in this aircraft. Should an inadvertent spin occur, the following
recovery procedure should be used:
1. Retard the throttle to idle
2. Centralise ailerons
3. Apply and hold full rudder opposite to the direction of rotation
4. Move stick progressively forward far enough to break stall
Hold these control inputs until rotation stops
As rotation stops, centralise rudder and make a positive, smooth recovery from the
resulting dive
