Wing Re-installation:
1.
Thoroughly clean and lightly lubricate all the wing supports and bolts with grease
before assembly. Also grease the flap root slot.
2.
Have one person hold the wing tip (supporting it on the spar, not the composite tip), a
second person to hold the leading edge wing root and a third person the trailing edge
wing root.
3.
Raise the tip to shoulder height.
4.
The upper wing suspension should now be carefully inserted into its location in the
fuselage. Take care to avoid damage to the pitot plumbing on the port wing half, and
any navigation light wiring. Insert the pin, with its head facing forward and tap it into
place.
5.
Lower the wing tip so that the lower suspension point is aligned; then insert its pin.
6.
At the trailing edge, align the flap operating pin in its slot in the flap end. This is
facilitated by moving a wing tip forward a little.
7.
Install the bolt into its rear wing attachment point, tapping it home gently.
8.
Secure all pins with their safety pins.
9.
Connect the aileron control rod and secure their connections.
10.
Connect the navigation lights and pitot-static hoses.
11.
Attach the wing root fairings.
3.2
Horizontal Tail Unit (HTU)
1.
Remove attachment bolts from the HTU-fuselage composite fairing.
2.
Disconnect the trim tab control cables (or wire where an electric trim tab is
fitted).
3.
Disconnect the elevator control rod.
4.
Remove the safety pins securing the castle nuts on the bolts of the stabilizer rear
supports. Remove the nuts and washers.
5.
Draw the HTU out of the fuselage.
Re-installation is the reverse of the above procedure. Lubricate the attachment points
before re-assembly. Check elevator and trim tab deflections and adjust as necessary.
3.3
Vertical Tail Unit
1.
Disconnect the rudder cables, attaching the ends together to prevent them from
slipping inside the fuselage.
2.
Remove the safety pin from the lower hinge bolt; remove the castle nut and washer.
3.
Repeat this operation for the upper hinge bolt.
3.
Remove the rudder.
Re-assembly is the reverse of the above. If necessary, insert a washer to adjust the lower
hinge clearance. Use tab washers to secure the bolt heads.
4.
Inspections and Scheduled Maintenance
4.1
Pre-Flight Inspection
A pre-flight inspection should be repeated prior to each flight even during the same day.
The pre-flight inspection is a visual check of the aircraft for deformations, surface damage, fuel and
oil system leaks, prop damage, insecure locks, covers and cowlings, vortex generators (VGs) etc.
Any damage or failure should be repaired immediately if airworthiness is affected.
