The high cost of replacement of helicopter transparencies is of serious concern to the U.S. Army. A recent study of 412 windshield replacement actions revealed that the average replacement occurred every 307 flying hours. As a result of this concern, the Army contracted for a systematic study of the design, test, and acceptance criteria for helicopter transparent structures to improve the overall reliability and maintainability of these transparencies. Data were collected and analyzed; existing criteria were evaluated for effectiveness and relative importance for different classes of helicopters; and recommendations have been made for detailed design objectives, testing, and acceptance criteria. The data collection on which these recommendations were based include both objective and subjective data. Extensive interviews with operational and maintenance personnel provide a broad 'real-world' basis for evaluation of the statistical tabulations of transparency replacement actions. (Author)
