6. Permanent Repair to the Canopy Transparency
To make a permanent repair, do the following standard procedure:
1. If necessary, remove the canopy for the repair.
Put the canopy on a firm working surface with
the crack horizontal.
2. If the canopy will stay on the aircraft for the
repair, put protective covers over the inside of
the cockpit.
3. Mask the area around the crack on the inner
and outer surfaces of the canopy.
4. Use a high-speed grinder to cut a groove along
the crack on the outer surface of the
transparency.
5. On the outer surface, countersink the
temporary stop-drill holes.
6. On the inner surface, seal-off the stop-drill
holes with masking tape.
7. Apply filler to the groove and stop-drill holes
until the filler is proud of the transparency
surface. Leave the filler to cure.
