| Title |
| Guide to Life Usage Monitoring and Parts Management for Aircraft Gas Turbine Engines |
| Scope |
| The effectiveness of Engine Life Usage Monitoring and Parts Management systems is largely determined by the aircraft-specific requirements. This document addresses the following areas: safety, life-limiting criteria, life usage algorithm development, data acquisition and management, parts life tracking, design feedback, and cost effectiveness.<p>It primarily examines the requirements and techniques currently in use, and considers the potential impact of new technolog to the following areas: parts classification and control requirements, failure causes of life-limited parts, engine life prediction and usage measurement techniques, method validation, parts life usage data management, lessons learned, and life usage tracking benefits.<p>SAE ARP1587 provides general guidance on the design consideration and objectives of monitoring systems for aircraft gas turbine engines. A major function of these Engine Monitoring Systems is to monitor the usage of life-limited parts in order to maximize available life and to enhance aircraft safety.<p>The purpose of this document is to review the current approaches to Engine Life Usage Monitoring and Parts Management. The document also serves to provide a summary of the many varied requirements of aircraft turbine engine life usage monitoring and parts management and a description of the means by which these requirements can be achieved more effectively through the use of engine monitoring systems. |
