Objectives of this task:
To final fit the wings to the fuselage. This is a repeat of the Pre-Paint task but because you
have already pre-fitted the wings they can now be fitted into place more easily. This task will
discuss the fitting of one wing at a time.
In our factory we use 3 people for this task, so ask 2 friends over to help you.
Do
not try to do this task with less than 3 people or you risk dropping the wing.
Preparation
Place 2 trestles beside the fuselage and lay
the wings on them.
Fit the bottom of the strut to the lower
fuselage mount and secure with an AN175-
15A bolt inserted from the front and an
AN960-516 washer MS20365-528 nut. Rest
the outboard end of the strut against a saw
stool as shown at right.
Lay the AN4-14A wing attach bolts and
some AN960-416 washers on top of the
fuselage where you can easily reach them.
Fit the wing
One person holds the outboard end of the wing while the other 2 hold the front and back of
the wing root as shown in the photo above.
Carefully walk the wing in to the fuselage, feeding the aileron cables through the fuselage
holes and feeding the fuel lines, stall warning tube and any electrical wiring, and guide the
wing attach lugs on the wing into the aluminium wing attach brackets on the fuselage.
The fit between the wing attach lugs on the wing into the aluminium wing attach brackets will
be tight and it may take some careful positioning of the wing to get them to fit – the outboard
end of the wing may need to be moved forward or backwards to get the correct alignment.
