The access holes are cut in the correct places in the fuselage top.
The access covers which have been made from 4 ply’s of bid laid up on the slash mouldings are cut to fit the holes and covered with release tape in preparation for the layups in the inside of the top.
2 ply’s and 2 re-enforcing ply’s are laid up. After cure the panes are removed. The layup is then cut out to leave a flange for attaching the Anchor nuts for the access panes
