Decision diagram approach to “on condition” philosophies

Abstract

Very often it is not possible to recognise deterioration of failure resistance in complex devices while they are installed on the aircraft and out on the airline. In such cases operational failures may occur. The failures do not all occur at the same age, however, because the resistance to failure and the environmental stress of two pieces of nominally identical equipment are not the same.
