6.2.5 SCRATCHES
Scratches on clear plastic surfaces can be removed by hand buffing and polishing using Plastic
Polish available from JABIRU as Part No.: NOVUS#2.
NOTE: Rubbing plastic surface with a dry cloth will build up an electrostatic charge which will
attract dirt particles and may eventually cause scratching of the surface. After applying polish,
dissipate this charge by rubbing surface with a slightly damp chamois. This will also remove
dust particles which have collected while wax is hardening.
6.2.6 CRACKS
When a crack appears, drill a hole at the end of the crack to prevent further spreading. Hole should
be approximately 1/16 inch in diameter, depending on length of crack and thickness of material. A
slightly dull unfluted drill should be used.
6.2.7 REMOVAL
As the windscreen and windows are bonded into the fuselage, it is not possible to remove them
without destroying them. Once windows have been broken out, any screws used in the original
installation should be removed.
6.2.8 INSTALLATION
Ensure all old epoxy resin has been removed from the fuselage sealing strips (around the window
frames).
Check new windscreen for fit. File or grind away any excess material to ensure a close fit. Do not
attempt to cut with any type of saw.
Wet the window frame joggle with raw epoxy resin. Apply a bead of Epoxy & Flock around the outer
edge of the windscreen.
Place windscreen accurately over the sealing strips and locate with one screw top and bottom.
Fit other screws.
Take care not to crack windscreen when installing. DO NOT over tighten screws
– cracking will
result.
