Exercise care to prevent the removal of laminate from the fuselage when
cutting and removing the sealant from between the fuselage and window. If
laminate is damaged, it must be repaired prior to installing the window.
If window is being replaced, it will be easier to use a die grinder and a cut-
off disk to cut out the inner portion of the window to gain access to the
bonding flange. The window should be cut as close as possible to the fuse-
lage.
