JACKING

GENERAL

Three jacking points, when equipped with jacking pads,

are used to lift the aircraft. The forward point "A"

is located forward of the nose landing gear. The points

"B" and "B" are located outboard of the engine pylon.

A safety jack positioned at the rear of the aircraft

prevents the aircraft from tipping up.

LIMITATIONS

The open air jacking operation is limited if the wind

velocity exceeds permissible values which depend on

aircraft gross weight and center of gravity position.

In any condition, the aircraft must be pointing upwind.

PRECAUTIONS

The three jacks have to be operated together. The

aircraft has to be lifted so that the landing gear can

be operated in the "Landing gear shock absorbers

deflated, flat tyres" configuration.

As soon as the jacking operation is finished, position

the safety jack as a tail stanchion.

JACKING POINTS

Jacking pads have to be used under the jacking points

to spread the loads.

LEVELLING

To ensure that excessive side loads are not placed on

the jacks and on the aircraft structure, a quick

levelling check must be carried out during the jacking

operation.

The aircraft attitude monitor is located in the

Refuel/Defuel control panel recess.

The "D4" position corresponds to a longitudinal angleof 0

oand a lateral angle of 0

o.
