2.1 Ground Handling
2.2 Towing the aircraft
Moving the aircraft by hand is done by using the wing struts and landing gear struts as push
points. Since there is no tow bar applicable at the nose gear, you have to press down and hold on the left
side of fuselage adjacent to the fin to raise the nose wheel off the ground. With the nose wheel clear of
ground, the aircraft can be turned by pivoting it about the main wheels.
2.3 Hoisting
The aircraft may be lifted by points designed for this purpose - the aircraft rear section may be
lifted by hand by use of the grip rail on the left side of the fuselage, or by the underside of the rear
fuselage lattice-work, preferably by use of tube gussets if possible, so that the fuselage part being lifted
can be supported with a soft pad on the lattice-work tubes of the fuselage, or on a stand under the tail-
wheel landing gear. The aircraft must be chocked on all wheel to prevent any undesirable movement.
Load relief of landing gear one side. To relieve the load on one side of the landing gear, lift that side of
the aircraft by the wing strut attachments points to the required height. This method cannot be applied for
a long-term aircraft supporting, it may be used for a momentary, short-term lifting of the aircraft only.
When jacking the whole of the aircraft firstly make ready a block padded on one side with a soft material.
We will use this block to support transversely the front part of the fuselage and, using two jacks, jack the
aircraft fuselage up to the required height. Furthermore, prepare a fixing stand to be located underneath
the aircraft, thus assuring stable support and positioning for the whole aircraft. To jack-up the aircraft, you
can also use special jacking stands designed for large aircraft if the size and frame configurations are
appropriate.
2.4 Jacking
Refer to paragraph 2.3. The aircraft does not feature further jacking points except for changing
main wheels. Doing so requires one person to lift the aircraft by pushing up at the points where the struts
connect to the wing, while a second person has to put a jack beneath the main wheel axle. A piece of
foam must be inserted between the jack and the wheel axle so that no damage will occur to the paint.
2.5 Parking
Parking precautions depend principally on local conditions. As a general precaution, apply the
parking brake or chock the wheels and lock the controls. It is often found a safe precaution to tie down the
aircraft as outlined in paragraph 2.6. if a hangar is not available even in weather not deemed a threat to
the aircraft. Weather conditions often change rapidly and many aircraft have been saved by the use of tie
downs.
2.6 Tie-down
When parking the aircraft in the open, point the aircraft into wind if possible. Secure control
surfaces by using suitable locks or clamps and set brakes.
After completing this procedure, proceed to tie the aircraft down as follows:
Tie ropes to the wing tie-down fittings (strut-wing attachment point). Secure the opposite ends of
ropes to the ground anchors.
Secure a tie-down rope (no chains or cables) to the exposed propeller shaft (between the cowling
and the spinnner) and secure the opposite end of the rope to a ground anchor.
Caution
Do not apply the parking brakes during cold weather (when accumulated moisture
may freeze the brakes) or when brakes
are overheated.
