Aircraft Transparencies

Our air carrier customers have seen the value in our transparencies in cost savings, reliability, and industry-leading warranty. These  windows  are rebuilt  under a tightly controlled  repair  specification  and  are  tagged  with  a  standard  Dual  Release  FAA 8130-3 to document their airworthiness.

Since 1987, Pacific Aero Tech has been at the forefront of analyzing the common failures necessitating the early removal of cockpit windows. In 2011, we put this knowledge and experience to work by investing heavily in the capital equipment, technology and people to broaden our capability to include the full rebuild of transparencies. The fleets and positions we targeted were directly influenced by those that seemed to have the highest failure rates; namely the 737, 757, 767 and 777 fleets. Now after nearly a decade of rebuilding the transparencies, we have surpassed our 2,000th window shipment. Importantly, we have incorporated small tweaks in the repair to address the common failures in the OEM windows.
