The size and weight of these jigs and fixtures shall be so that they fit the established means of transportation and so as to ensure a secure fastening during shipment. As additional protection, it is recommended to cover the outer areas with polyethylene sheet (in case of sea shipments, this requirements becomes mandatory).
CAUTION: During shipment, secure the control surfaces against free or accidental movement; at the same time, secure in position those parts of the control systems that, by free motion might damage the airframe.
14.4. Lifting of airplane
Level of certification needed: Owner
For loading-unloading or assembly-disassembly work on the airplane or landing gear, it is necessary to lift the airplane partially or completely.
a) Complete lifting of assembled airplane 
Use 4 pieces of string or textile belt with an ultimate resistance of at least 400 daN and a length of about 4 m each (or two pieces of 8 m each). Working procedure:
1.
 Dismount the wing-to-fuselage fairing;

2.
 Tie the lifting strings to the wing-to-fuselage joint fittings, at frames no. 1 and no. 2;


3.
 Tie the strings to the hoisting device, located above the cockpit, so that the taut belts are of approximately equal length;

4.
 Slightly lift the airplane from the hoisting device, until the belts are taut, and check the assembly: secure ties, symmetrical tension, approximate horizontal position of airplane;

5.
 Lift the airplane, and, carefully handling it, move it to its new location, or lay it on supports. Put resting supports in the tail skid area and in frame no. 1 area.

6.
 Untie the straps and secure the airplane against displacements. Reinstall the fairing, if applicable.


CAUTION:
1.
 Minimum lifting force of hoisting device: 1 500 daN.

2.
 While the airplane is lifted, do not stay under the airplane, unless it rests on supports.


3. The resting supports must be fitted with soft protection elements (sponge, felt, rubber pad etc.), so as to avoid local structural damages.

b) Partial lifting of airplane
The partial lifting of the airplane is necessary in case of work on the nose gear or on one of the main gears.
 Working procedure:
a)  For work on nose gear:
1.  
Brake the main wheels by means of the parking brake, and set chocks at the main wheels;

2.  
Prepare a supporting jig for the cockpit frame no. 1, so that the airplane supported by it has the nose wheel lifted off the ground. 

3.  
A person drags down the false tailwheel until the airplane nose is lifted as much as necessary, and another person places the supporting jig under frame no. 1;
