FORWARD CANOPY LIP
.....
In order to provide a secure seal at the forward edge of the
canopy frame, a fiberglass lip is fabricated from 4 BID and bonded to
the inside of the upper forward fuselage shell as shown.
.....
Since the forward edge of the canopy frame is curved, when viewed
from above, the lip will also be curved.
.....
To construct the lip, place some gray tape around the canopy frame
cutout on the upper forward fuselage to protect the structure. Next,
laminate 4 BID around the cutout with a minimum width of 2". Multiple
pieces may be used to make the required curvature.
.....
When the piece is cured, remove it and the grey tape, and bond it
to the inside fuselage skin, At least 0.6" must project aft from the
cutout to provide the lip. A 1 BID closeout ply is laminated to cover
the exposed foam edge of the shell lapping onto the lip, and knife
trimmed even with the outside skin of the shell.
