8.9 JACKING
The aircraft may be jacked in order to service the landing gear, change wheels/tyres and to
perform other service functions. The procedure for jacking the aircraft is as follows:
a.
Place the main jacks under the jacking points located on the wings just outboard of the
wing strut attachment. Jacking adaptors are required to suit the actual types of jacks
used and to locate the jacks positively during the exercise.
b. Place a suitable fixture through the tail’s tie-down point and jack up from this point.
c. Raise the jacks until the wheels are clear of the ground as required.
CAUTION:
EMPTY WEIGHT LONGITUDINAL CENTRE OF GRAVITY FOR THIS AIRCRAFT
TYPE IS IN THE VICINITY OF THE MAIN JACKING POINTS. THEREFORE,
THE TAIL JACKING POINT MAY BE REQUIRED TO BE HELD DOWN RATHER
THAN LIFTED UP. IF THIS IS THE CASE, TWO COURSES OF ACTION ARE
AVAILABLE. THE TAIL MAYBE HELD DOWN BY THE VENTRAL FIN TIE
DOWN USING ROPE ATTACHED TO THE GROUND OR HEAVY WEIGHT.
ALTERNATIVELY IF USING A LIFTING JACK, WEIGHTS CAN BE PLACED ON
TOP OF THE TAILPLANE NEAR THE ROOT SECTION.
8.10 LEVELLING
The aircraft will be longitudinally level when the two marked level points on the left hand side of
the fuselage are at the same elevation. This can be determined by using a water level.
Alternatively a suitable spirit level may be used over the top surface of the seat attach fittings on
the cabin floor. Both longitudinal and lateral levels may be determined this way.
8.11 FLUID SERVICING
8.11.1 Fuel System
Filling Fuel Tanks Observe all the required precautions for handling fuel and filling tanks.
Ensure that the aircraft is bonded to Earth using the earthing point provided just behind the front
door step on either side of the aircraft. Additionally prior to opening the fuel cap the earth strap
on the refuelling nozzle should be attached to the earthing point adjacent to the tank filler neck.
Fill the tank to within 25 mm of the top of the tank. Once refuelling has been completed, turn on
the master switch and note the fuel gauge readings as a check.
Fuel Draining/Sampling Five quick drain fuel drain fittings are provided in the GA8-TC 320 fuel
system. There is one for each main fuel tank located on the lower rear inboard corner of the tank
and three on the lower right hand side of the fuselage below the front door to drain the sump
tank and strainer bowls. Fuel should be drained/sampled from all of these points before the first
flight of the day and after each subsequent refuelling.
Draining Fuel System The complete fuel system may be drained by the using the five fuel
drain points.
