The U.S. Air Force has historically rejected the notion of using repaired windowswindshields WWS. With increasing pressure to reduce fleet operating costs and based on the favorable experience that commercial fleets have had, interest in using repaired WWS is receiving greater attention. To ensure that repaired WWS are safe and that they provide similar benefits for the Air Force, a program of evaluation and testing was undertaken to compare new and repaired CKC-135 WWS. Optical and electrical properties, pressure integrity, and bird impact resistance of repaired and new WWS have been evaluated. The bird impact test results are the first data that the Air Force has collected for CKC-135 WWS. The functional testing indicated that repaired WWS are not equal to new WWS the new WWS outperform the repaired WWS. In terms of removal for cause criteria and absolute performance requirements, however, the repaired WWS appear to be good enough. Concerning costs, the direct costs for repair of the WWS in this program ranged from 65-75 of new WWS cost, suggesting that money can be saved.
