Abstract : The purpose of this paper is to examine the application of small crack propagation data to the design of aircraft structures. No deliberate attempt is made to cover peculiarities of engine construction. It is intended to generate a questioning attitude within the audience to exactly how small crack data will be applied and to what benefit. It is not the intention to provide the answers! Indeed the questions asked may not be thought by some of you to be those most in need of answers. So be it. Any debate which results can only be healthy for research and design.
