4.1 Wing
4.1.1 Wing Structure
The wing of CT consists of right and left wings made of carbon and fiberglass composite parts bonded
together with structural epoxy resin. The wing is attached to the fuselage by means of a carry through
structure developed by extensions of both right and left wing spars fixed together by two main bolts in the
cabin.

The wing structure includes the skins (upper and lower), spar, and ribs. The brackets for aileron and flaps
hinges are attached to the ribs along the trailing edge. The aileron control rod runs behind the spar. Two
fuel filler caps are on the upper wing surface. An access panel is located on the lower skin of the wing,
and inspection and maintenance holes are along the trailing edge of the wing.
The upper and lower skins are made of epoxy/carbon fiber and foam core. The spar caps are of
epoxy/carbon fiber and the spar web is of epoxy/glass fiber and foam core. The ribs are made of
epoxy/carbon.
Move the wing tips slightly forward and backward, there should be no play and noise. If there is play or
noise, pull the wings about 20 cm out (see p. 4.1.2) and check if the root rib, especially at the pin area
has no cracks or damages.
If there is not damage but some play between fuselage and wing root rib, washers can be used to
compensate.
