An Approach to Maintainability and Ground Checkout of Aerospace Electrical Power Systems

Present aerospace electrical systems have not been designed for maximum maintainability, and no really effective maintainability program has yet been established in the industry. A definition of maintainability requirements for aircraft electrical systems and examples of recent efforts to reduce the maintainability cost of present electrical systems are given. Probable future designs are discussed and recommendations are given to establish a total maintainability program. It is suggested that each aircraft user establish a maintainability program, and actively participate in the writing of future procurement specifications.
