Economic and Safety Aspects of Prolonging Engine Life

Abstract

It's been nearly 20 years since the introduction of commercial jet powered aircraft. The powerplants which made these aircraft possible have proven to be extremely reliable. “Prolonging Engine Service Life” became a natural economic objective of the airlines, and the initial practice of overhauling engines at specified intervals gradually evolved into the current on‐condition maintenance concept designed to minimise operating costs. While these practices and extensive parts repair activities resulted in major economies, the resultant extended operation of hardware has in many cases caused more frequent engine removals and often ultimately more extensive parts replacement. In addition, engine fuel consumption has been compromised to varying degrees.
