2.

Tools and Equipment

The following tools and equipment are required for the repair of the cockpit transparency:
- High speed grinder
- Drill
- UV light (cold).
3.

Materials

The following materials are required for the repair of the cockpit transparency:
Filler ACRYFIX 192
Masking Tape
Transparency polish (Micro - Gloss Liquid Abrasive)
NOTE: A UV-light (cold) is required to cure ACRYFIX 192.
4.

Fillers

To compensate for the shrinkage of the fillers during the cure process, the filler must be applied proud of
the transparency surface. As this is not possible when repairing a vertical crack in-situ, a strip of masking
tape must be rolled up over the repair while simultaneously applying the filler. This procedure must be
repeated until the filler is proud of the transparency surface.
5.

Temporary Repair to the Canopy Transparency

To prevent further propagation of cracks before a permanent repair is possible, stop-drill the ends of the
crack with a 0.1 in (2.4 mm) diameter hole.
