Recognizing that corrosion reduces productivity and equipment availability and ultimately costs s24 billion annually, the Navy seeks a "pro-active," comprehensive aircraft and engine preservation program. Significant advances in preservation technology are occurring - Navy preservation techniques need upgrading. This project will provide the basis for a sound, state-of-the-art aviation and engine preservation program . It will identify the technologies, equipment and practices to satisfy current and future preservation requirements in an efficient and effective manner. Background information, preservation environment requirements, comparative programs, state-of-the-art techniques and equipment, programmatic data and recommendations will form the basis for a comprehensive program to meet evolving Navy requirements. This project will develop the knowledge and data essential for cost-effective and efficient approaches to Navy' preservation requirements. The project will further outline a program that addresses the preservation considerations that must be accommodated and present a road map for Navy aircraft and engine preservation program development.
