Army helicopter nonrotating flight control system specifications, standards, and design handbooks were reviewed for areas in which improvements could be made to requirements affecting system and mission reliability and maintainability. R and M requirements were essentially missing from all documents reviewed, and therefore specific requirements were added for reliability, maintainability, and supporting workmanship, qualification, and production acceptance. Special emphasis was directed toward requiring those distributional material properties, failure and maintenance time data, and analytical methods which permit Design for Reliability Probabilistic Design and Maintainability directly into components and thus into the flight control system.
