WINDSHIELD.
REMOVAL AND INSTALLATION OF WINDSHIELD. (Refer to Figure 56-1.)
1. Remove the collar from around the bottom of the windshield and the trim strip from between the windshield
halves by removing the attaching screws.
2. Remove the windshield by raising the lower portion of the windshield and carefully pulling it out and down
to release the top and side edges.
A damaged windshield should be saved to provide a pattern for shaping the new
window.
3. Clear old tape and/or sealer off the affected mating surfaces.
4. Cut or grind the new windshield to acquire proper dimensions.
5. Isocrylic sealant as described in Chart 9105 (per PMSC1012-2-2), is used to provide a resiliant seal for the
windows. Proceed as follows:
A. With the protective covering left on, force round bead solvent (PMSC1012-2-2) into the bottom of the
windshield channel starting at the top center and continuing to the lower end of the channel on the side
of the fuselage. After the sealant is firmly and completely seated in the bottom of the channel, remove
the protective paper.
B. Firmly press tape type sealant (PMSC1012-2-6) over the edge of the windshield that runs from the top
center down to the side of the aircraft. Equal width of tape should be on each surface of the
windshield. Remove the protective tape.
6. Insert each windshield into its fuselage channel. The excess sealant will "squeeze-out— but should not be
trimmed away immediately.
7. Insert each windshield into its fuselage channel allowing clearance between the two windshields for
expansion.
8. Firmly apply sealant tape to the surfaces of the windshield retaining trim strips and then remove protective
paper.
9. Install trim strips.
10. A tool made of acrylic sheet with a wedged end (.25 inch thick and 1.5 inch wide) should be used to trim
away excess sealant.
