(2) Installation - Windshield (See Figure 56-103) and (See Figure 56-104)
Windshield sealant is intended to provide a seal between the windshield and fuselage and to
prevent the leakage of air through the airframe structure. Window sealant is used in the installa-
tion of all windows in the aircraft.
Isopropyl alcohol, kerosene, white alptha naptha, mineral spirits, and cotton are acceptable for
cleaning acrylic windows. Residue left behind by the “Spraylat” protective coating may be
removed by soaking the area with isopropyl alcohol and rubbing with an alcohol soaked soft
flannel cloth. Residue left behind by the adhesive backed paper covering can also be removed
by the above method. If, however, the paper covering has been stored on the windshield for an
extended period of time, soak paper with kerosene and keep it wet for several hours. Remove
any remaining adhesive by using a mixture of equal parts of kerosene and isopropyl alcohol.
Soak a soft flannel cloth with this mixture and rub the windshield with the cloth. The windshield
should be cleaned after this procedure with a dish washing liquid and plenty of water.
WARNING:
Never use organic solvents such as Methyl Ethyl Ketone (MEK), acetone, or
lacquer thinner. Do not use jewelry cleaner or paper towels to remove any
contaminates. Never use ice scrapers on acrylic windows. Do not store any
window outdoors while the protective covering is still on the window. The
covering will become very difficult, if not impossible, to remove without
damaging the windshield.
CAUTION: It is very important to keep the windshield well supported at all times. Warm tem-
peratures are not required during these operations; however, acrylic will take
much more abuse at 80 degrees than at 30 degrees.
Note: Before final installation, always inspect the windshield for imperfections. Use care
to prevent staining or scratching the windshield.
