PPG Aerospace to Redesign Windshields for Boeing
Next-Generation 737 Airplanes
August 14, 2009
Spirit AeroSystems has contracted PPG Industries' aerospace transparencies
business to redesign the laminated glass windshields for Boeing's
Next-Generation 737 planes.
The windshields are being redesigned at Boeing's request to accommodate
airframe improvements, according to a statement released by PPG.
To meet Boeing specifications, the redesigned windshields will be
slightly smaller than the current versions and include an inboard
plastic anti-spall liner to prevent broken glass from entering the
flight deck during a bird-strike event, according to Art Scott,
PPG Aerospace global sales director for commercial original-equipment
"Boeing has asked for an alternate approach to bird-strike
performance for the windshields that works structurally with the
737 airframe," Scott says. "Adding an anti-spall liner
to the windshields for Next-Generation 737 airplanes enables Boeing
to keep the structural airframe design while incorporating newer
PPG will be the sole source of the redesigned windshields for production
and aftermarket applications, according to yesterday's statement.
Scott said PPG expects certification of the new-design windshields
in the second quarter 2010. The windshields will be designed and
manufactured at PPG's Huntsville, Ala., facility for delivery to
Wichita, Kan., where Spirit makes the fuselage for Boeing.
