MAINTENANCE MANUAL EXTRA 330LX
55-00-00 GENERAL
The EXTRA 330LX has a conventional empennage with
stabilizers and moveable control surfaces. The spars consist
of carbon roving caps, carbon fibre webs and PVC foam
cores. The shells of the horizontal and vertical tail are built
of honeycomb sandwich with carbon fibre laminate. Also
buckling is prevented by plywood ribs. On the R/H elevator
half a trim tab is fitted by means of two hinges.
The layer sequences of the horizontal and vertical tail are
shown in figures 1, 3 and 4.
For protection against moisture and UV radiation all com-
posite parts are coated with an unsaturated polyester gel-
coat, a filler and finally with paint.
For repair of composite parts refer to chapter 51.
