FOREWORD

The purpose of this handbook is to provide Army design engineers with guidelines to assist them in incorporating maintainability into Army materiel early in research and development. Information collected from maintenance records provides practical examples-good and bad-that illustrate the design principles that result in maximum maintainability. The designer can use these principles to build maintainability into materiel and thereby contribute substantially to solving the Army's maintenance problem.

Chapter 1 is an introduction to the principle of maintainability, its importance, and methods of achieving it. The following LO chapters-simplification, standatdization and interchangeability, accessability, modularization, identification and labeling, testability and diagnostic techniques, preventive maintenance, human factors, and environmental factors-describe in detail their role in achieving the maintainability principle.

This handbook was developed under the auspices of the Army Materiel Command's Engineering Design Handbook Program, under the direction of the US Army Management Training Activity* The handbook was prepared under the direction of and edited by the Research Triangle Institute under Contract No. DAAG-34-73-C-005 1.
