Report of further work into the study of the dissemination of information relating to the reliability of aircraft and their equipment

This report describes the work that has been carried out during the six months extension to the first ARB Research Fellowship. Information has been produced which is intended to be of use to reliability, design and development engineers, in the following areas: i) A document has been written which contains statistics relating to the unscheduled removal rates of some 250 components fitted to twelve commercial transport aircraft types. Some analysis of reliability trends, has also been performed. ii) A reference document has been produced which summarises ten source documents relating to component reliability information, and gives some of their users' comments. iii) A study has been performed to examine the role of independent overhaulers in the reliability information chain. Problem areas are described, together with suggestions for improvements. Starting in 1946 as the College of Aeronautics, the Cranfield Institute of Technology was granted university status in 1969. In 1993 it changed its name to Cranfield University.
