Wings disassembly
First of all, drain off the fuel from both wing tanks.
Inside the cockpit, disconnect ailerons pushrods from the control stick and flaps pushrods (in the central
tunnel).
Release and remove the locking nut of the wing pins bolt. Screw the bolt out by approx. 2cm.
If needed, the assistant (holding the wing by the wing tip) can slightly lift the wing to allow the pins to be
pulled out more smoothly.
Beat out the lower pin by the hammer by light tapping on the head of the bolt. Unscrew the bolt and
remove the lower pin. Push out the upper pin with a
help of any metal rod of Ø 18mm
and the hammer.
The assistant still holds the wing by the wingtip and you hold it by the root (the third person can hold the
wing by the trailing edge near its root) to avoid its fall and damage.
After the pins are removed, partially pull the wing out of the fuselage to have the space between the wing
and fuselage and to have enough access to disconnect the equipment. Support the wing at the area of its
root rib with a help of the assistant (or you can support it by your knees) to be able to disconnect the rest
of the equipment. Then disconnect:
- static and dynamic pressure hoses of the Pitot tube (only on the left wing)
Note: Pay attention not to interchange the hoses of the Pitot tube during their next re-assembly.
- quick couplings of fuel hoses
- cable connector of the fuel gauge
- cable connector of the strobes/position lights (if equipped with)
Store the wings on any safe and dry place with stable temperature. Wings need to be properly secured and
prevented from structural and surface damage.
