Review of Engine Maintenance Concepts Applied to Wide Body Jets

In the early design stages of the advanced technology high-bypass-ratio engines, it became evident that maintainability considerations and more effective maintenance concepts would be necessary to achieve higher reliability and more economically successful powerplants. This paper reviews the major design considerations from a maintainability standpoint. It describes the concepts developed specifically to provide more effective maintenance for the wide-body jets. It discusses the effectiveness of these programs, and provides an insight into new philosophies and trends envisioned by the Federal Aviation Administration for future maintenance management programs.
