8.11.2 Engine Lubrication System
Filling the Engine Sump. The engine sump should be lled to the operating level with the
lubricating oil specied in paragraph 2.4.4. This may be accomplished by using a suitable funnel
inserted in the oil ller tube located on the top of the engine. An access cover is provided in the
engine cowl for this purpose.
Draining the Sump. The engine sump is drained by removing the lower engine cowl and
removing the sump drain plug (or using the quick drain valve if tted). Ensure that the sump plug
is correctly replaced and lock wired prior to relling the engine with oil.
8.12 WHEEL BRAKE SYSTEM
Brake System. The brake system utilises two foot operated brake cylinders with integral uid
reservoirs. The brakes do not require adjustment of pad clearances. If the brake pads show
signs of excessive wear, they should be replaced.
Park Brake. The park brake is a one way valve incorporated in the Brake system. The park
brake is actuated by raising park brake knob on the centre console and then applying both
foot brakes. To release the brakes, press the park brake knob downwards.
Filling Brake Cylinders. This is accomplished from inside the cockpit by removing the
plug from the top of the cylinders and lling with mineral based hydraulic uid to specication
MIL-H-5606. Ensure that no contaminants are allowed to enter the reservoir, particularly when
removing or replacing the plug.
8.13 LANDING GEAR
Because of its simplicity, the landing gear does not require complicated maintenance. The main
landing gear leg requires no maintenance except for an occasional clean around the fairing to
remove dirt, grime and grass and inspection of the brake hoses. The nose gear requires the leg
to be clean for smooth operation. Bolts and bushes should be inspected regularly and if worn
excessively, replaced.
