ATA 56 – Windshield Surface Seal Update
All
PPG, the supplier of the aircraft cockpit windshields, has reformulated the Surface Seal® Gen II coating to the Surface Seal® Gen III. The purpose of the coating is to provide improved water shedding performance during precipitation conditions. The formulation change was introduced because of PPG’s commitment to providing environmentally sustainable products and evolving regulation while not reducing the water shedding performance.
On June 1, 2020, the existing Surface Seal® Gen II coating will become obsolete. After this date PPG will provide only the new Surface Seal® Gen III coating whether it be for spare windshields or PPG kits used for refurbishing the coating. Any stock of spare windshields and existing Surface Seal® Gen II kits can continue to be used until the supplies are exhausted. If after June 1 you place an order with Textron for the existing Surface Seal® Gen II kit the new Surface Seal® Gen III kit will be provided instead.
The Aircraft Maintenance Manual (AMM) is being revised to address the change, but this communiqué provides the necessary information before the revision will be available. SEE ENTIRE COMMUNIQUE for specific information at www.txtavsupport.com.
