4.7.1.2
Lower surface
The ailerons are to be sealed at the lower surface with 38 mm wide Teflon-
glass fabric tape. The Teflon-glass fabric tape must be glued 10 mm (.4 in.)
wide to the lower wing surface. PVC tape (19mm wide) is glued over the
leading edge of the sealing to protect the sealing from coming loose.
a) Removing the ailerons
To remove the ailerons you have to remove the Teflon-glass fabric tape
first. Peel off carefully so that the tape does not tear and no remains of the
glue remain on the wing surface.
b) Reinstalling the seal
Remove carefully any remains of the glue. Install the aileron in the wing
but don't screw on the control surface horn.
Rotate the wing upper surface up and deflect the aileron to its max.
negative displacement. Use a small brush and apply talcum powder onto the
aileron leading edge. Then deflect the aileron to its max. positive
displacement and remove the talcum powder from wing and aileron
surface.. Clean the gluing areas with Acetone.
Deflect the aileron to its max. negative displacement again and fix in this
position e.g. with tape. Glue the Teflon glass fabric tape to the wing with
10mm overlap.
Press the Teflon-glass fabric tape with a wooden stick into the gap between
aileron and wing and press the fabric tape to the aileron surface.
Then deflect the aileron several times in both directions. If there is still a
noise which sounds like the fabric sticking to the aileron and getting loose
again, you should blow compressed air into the fairing of the control
linkage pushrod to distribute the talcum powder.
Glue a PVC tape (19mm wide) over the leading edge of the seal.
Screw on the control surface horn, securing the bolts with Loctite 243.
Glue the fairing again to the control surface horn with polyester resin.
Apply pressure when gluing to prevent the fairings interfering.
