Maintainability Standards & Handbooks

MIL-STD-470B Maintainability Program Requirements for Systems and Equipment

This document includes application requirements, tailorable maintainability program tasks, and an appendix with an application matrix and guidance and rationale for task selection. The topics covered are program surveillance and control, design and analysis, modeling, allocations, predictions, failure mode and effects analysis, and maintainability design criteria. Each task item includes a purpose, task description, and details to be specified. Software maintainability is not covered by this document.

MIL-STD-471A Maintainability Verification/Demonstration/Evaluation

This document provides procedures and test methods for verification, demonstration, and evaluation of qualitative and quantitative maintainability requirements. It also provides for qualitative assessment of various integrated logistic support factors related to and impacting the achievement of maintainability parameters and item downtime, e.g. technical manuals, personnel, tools and test equipment, maintenance concepts and provisioning.

MIL-HDBK-472 Maintainability Prediction

This document is to familiarize project managers and design engineers with maintainability prediction procedures. It provides the analytic foundation and application details of five prediction methods. Each procedure details applicability, point of application, basic parameters of measure, information required correlation, and cautionary notes. The highlights of each maintainability prediction procedure are presented in a clear and intelligible manner and include useful supplementary information applicable to specific procedures. Maintainability Prediction Procedures I and III are applicable solely to electronic systems and equipments. Procedures II and IV can be used for all systems and equipments. In applying Procedure II to non-electronic equipments the appropriate task times must be estimated. Procedure V can be used to predict maintainability parameters of avionics, ground and shipboard electronics at the organizational, intermediate and depot levels of maintenance.

DOD-HDBK-791 Maintainability Design Techniques

This handbook supplies information on incorporating maintainability into Army materiel design. It defines maintainability and discusses its importance, quantitative measurement, and incorporation into the design process. Other subjects discussed in detail cover simplification, standardization and interchangeability, accessibility, modularization, identification and labeling, testability and diagnostic techniques, preventive maintenance, human factors, and environmental factors as they relate to maintainability.

MIL-STD-1591 On Aircraft, Fault Diagnosis, Subsystems, Analysis/Synthesis of

This document establishes uniform criteria for conducting trade studies to determine the optimal design for an on-aircraft fault diagnosis/isolation system. This document is applicable where a selection can be made between such alternatives as central computer controlled on-board centrally polled built-in test equipment (BITE), decentralized BITE, detached Aerospace Ground Equipment (AGE), etc., or combinations of the preceding. The fault diagnosis/isolation systems of interest are those used to diagnose/isolate faults at the flight line (organizational) level of maintenance. This document also provides a cost model and a maintainability labor power model.

MIL-STD-1843 Reliability-Centered Maintenance for Aircraft, Engines and Equipment

This document, which is based on the Airline/Manufacturer Maintenance Program Planning Document MSG-3, outlines the procedures for developing preventive maintenance requirements through the use of Reliability-Centered Maintenance Analysis (RCMA) for Air Force aircraft and engine systems, aircraft and engine structures and equipment, including peculiar and common Support Equipment (SE) Communications and Electronics (C-E) equipment, vehicles, weapons and other similar equipment items.

MIL-STD-2084 Maintainability of Avionic & Electronic Systems and Equipment

This document covers the common maintainability design requirements to be used in military specifications for avionic and electronic systems and equipment.

MIL-STD-2165A Testability Programs for Electronic Systems & Equipment

This document is intended to prescribe a systematic approach for establishing and conducting a testability program. It describes a uniform approach to testability program planning, establishment of diagnostic concepts and testability (including BIT) requirements, testability and test design and assessment, and requirements for conducting testability program reviews. Relevant tasks in this document are to be applied during the conceptual phase, demonstration and validation phases, full-scale development phase and production phase of the acquisition process.

DOD-STD-1701 Hardware Diagnostic Test System Requirements

This document establishes the general procedures, terms and conditions governing the preparation and completion of a hardware diagnostic test system.

MIL-STD-2173 Reliability-Centered Maintenance Requirements for Naval Aircraft, Weapons Systems and Support Equipment

This document is used to provide procedures for a Reliability-Centered Maintenance analysis for naval aircraft, weapons systems, and support equipment. This document is used during development of new systems and equipment, and by analysts and auditors within the Naval Air Systems Command for determining preventive maintenance requirements and developing age exploration requirements. The document can also be used to update the initial reliability-centered maintenance analysis and analyze newly discovered failure modes.

MIL-STD-001591A Subsystem Analysis/Synthesis of Command, Control & Communication (C3) System Component Fault Diagnosis

This document establishes uniform criteria for conducting trade studies to determine the optimal design for command, control and communication system and component fault diagnosis/isolation subsystems, These types of systems are referred to as Fault Identification & Test Subsystems (FITS). FITS include the hardware and/or software necessary for the detection and isolation of failures.
