8.6 Covering the Wings
a) Do not cover the wings until they have been inspected!
See the inspection schedule.
b) Select the odd-one-out from the battens: the trailing edge fitting is flat rather
than forked, lay this one aside for the cabin roof.
c) Select a typical batten and draw around it onto a large sheet of paper, to make
a template for checking the batten profiles later should this be required after
repairs etc.
d) Check the battens and their fittings for any sharp edges which might damage
the coverings.
Smooth the ends with glass paper or similar if necessary.
Polishing the battens with car wax makes them slide in more easily, but
on no account do this for aircraft with Dacron coverings if you intend to
paint or lacquer the aircraft, the reaction will not be a pretty sight!
e) With two people remove the wings from the fuselage.
Remove the lift struts from the wings followed by the fuselage, then
remove the wings from the fuselage and lay them down flat in a very
clean place.
Do not place the wings on concrete as it will scuff the cloth when you
cover the frame.
f) Apply a layer of clear, thin, lightweight self-adhesive plastic film, such as
Fablon, or clear waterproof tape, to the leading and trailing edge tubes and
wing tip tubes where they touch the covering.
Do not skip this step! This prevents vibration from abrading the
anodising, which can then cause unsightly stains visible through the
covering.
To save weight just apply the film where the cloth can touch the tubes.
If desired to increase resistance to corrosion it may be applied to the
whole circumference of every tube, which will protect these difficult to
clean areas.
Do not use thick, heavy tape, such as prop tape or gaffer tape, as this
adds too much weight, is too grippy, and can look horrible!
g) Thicker tape should be applied only to the U-brackets at the wing tips to
prevent chafing of the coverings.
