a. Although it is not necessary, the door may be taken off the airplane. If the door is removed, make
sure it is placed on a surface that will not scratch the painted finish of the door.

a. With the windows compared to each other, grind the new window to the same outlying dimensions
as the old.
b. With the frame thoroughly cleaned align the new window in the frame to ensure a proper fit.
c. Remove the new window and proceed as follows:
1. Apply 3/4 inch wide sealant tape to the contacting exterior surfaces of the window (around the
perimeter of the window that touches the door’s skin).
2. With the tape aligned on the window, apply pressure to force the seal against the window.
3. Remove the protective paper from the tape and set window in place on the door.
4. With a narrow, hand held, rubber roller, apply pressure around the perimeter of the window to
cause a tight seal between the window and skin.
d. Place new retainer into position and secure with 16 screws and washers (AN960-6).
e. Reinstall window retainer clips and trim panels.

perimeter of window. Allow sealant to dry.
