TECHNICAL DESCRIPTION, OPERATING, MAINTENANCE AND REPAIR MANUAL
2.6 Ground handling
2.6.1 Towing the aeroplane
The aeroplane can be displaced by means of towing the aeroplane at a short distance by
holding the blade. Handle the propeller by holding the blade root – never blade tip. For a
direction motion change push rear part of a fuselage close before a fin down to lift the nose
wheel, than turn the aeroplane into a required direction.
CAUTION
Avoid excessive pressure at the aeroplane control surfaces and
the wing tips. The perpendicular pressure on the surface of the
airframe sandwich shell thin skin layers can produce a creation
of a prints. These prints can weaken a sandwich shell. During
the aeroplane towing handle the propeller by holding the blade
root – never blade tip.
2.6.2 Parking the aeroplane
There is advisable to park the aeroplane inside a hangar or eventually inside other proof
space. During the aeroplane parking can be used a parking brake.
CAUTION
In case of a parking outside a hangar and at long term parking
to cover cockpit canopy by means of a suitable cloth dust-
cover, due to preclusion of the sun effect. The sunbeams
together with the optical action of the cockpit canopy may be
the source of the spot heating, which can create damage of the
cockpit area and the upholstery.
2.6.3 Mooring the aeroplane
The aeroplane is usually moored in case of parking outside a hangar or if need be. By this
reason the aeroplane is equipped with mooring eyes (GL) located ant wing lower surface.
The aeroplane moors to the ground by means of a mooring rope passed through the
mooring eyes.
There is also necessary to moor the nose wheel landing gear, to shut all venting holes ( a
side sliding window ), to block the control stick up e.g. by means of safety harness, to
close and to cover cockpit canopy.
2.6.4 Jacking the aeroplane
Since the empty weight of this aeroplane is relatively low there is easy to lift the aeroplane
without a special equipment. The aeroplane may be lifted by handling the following parts:
1. Push down the rear part of fuselage ( handle the fuselage before the fin ) to lift the
nose wheel and then support the fuselage under the firewall by means of a suitable
support.
2. For a complex check of the retractable undercarriage lift the aeroplane with help of the
holders at places assigned for this purpose. These supported points (SP) are located at
the wing central panel lower surface behind the auxiliary spar and at a firewall ( see
figure ).
