CHAPTER 2 Basic handling
2.1 (DIS) ASSEMBLING OF WINGS
2.2 (DIS) ASSEMBLING OF TAIL SURFACES
Warning:
(Dis) Assemble aircraft always on place with enough space to safely manipulate with the parts or with
whole aircraft.
In case of disassembling aircraft, be sure that you have enough right pads (soft, clean, height
enough) to
protect the wing from damage during storage (on ground for ex.).
During handling (hold/push/pull) aircrafts parts always touch in place of structural
reinforcement like ribs,
wall and beams (shortly in positions of rivets lines).
There’s needed to be at least two men to (dis) assemble wing safely.
Always keep all disassembled parts,
joining materials and others aircrafts items.
Used self-locking nuts replaced with new ones!
Disassembling of wings
− remove the covers inside the pilots cabin (flap control handle, under pilot, around the steering)
− disconnect aileron control rod from the steering joystick
− disconnect and blind fuel hoses from the wing-fuselage connection
− disconnect the pitot-static hoses in left wing connection – first mark the hoses with static
pressure and then disconnect to prevent wrong re-connection . Blind disconnected hoses
to prevent getting dirty inside
− after each re-assembling check proper pitot-static hoses connection and verify function
− disconnect electro-installation connectors from wing to fuselage
− remove self-locking nuts with washers from wing hinges on main and rear beam. (6+6
peaces on main, 2+2 peaces on rear one)
− remove bolts from rear hinges, remove bolts from main hinges except 1+1 in upper
hinges and except 1+1 in lower hinges
− one man holds the end of the wing and second one remove upper and lower bolts (little
up and down movement of wings end is required to release the bolts)
− one man holds the end and second one holds the wing root attachment. Move the wing
slowly out of the fuselage. During moving out, watch carefully the rod ball-ends, hoses,
connectors to avoid their damaging from edges. During moving wing out, automatic
disconnection of flap control happened, so it is better to hold the flap position during that act.
− Put the wing carefully on suitable pad ( watch out for the pitot-static tube under the wing –
had to be lifted)
− Same procedure for opposite wing
Assembling of wings
− Assembling means reverse procedure of disassembling
− During assembling it is required to connect the flap controls properly. For that it is needed
to set 0 positions on control flap handle and 0 positions on flap itself (that means trailing
edge in straight line). With that the flap control will re-connect automatically.
Disassembling horizontal tail surfaces
- remove fiberglass covers from stabilizer
- disconnect connectors for trim control and strobe lights in front cavity
- disconnect elevator control in rear cavity
- remove self-locking nuts, washers and 4 bolts connecting stabilizer together with fin.
- Remove horizontal tail surfaces and put it on suitable pad
Assembling of horizontal tail surfaces
- assembling means reverse operation mentioned above
