Primarily for general aviation discussion, but other aviation topics are also welcome.
zlhglp wrote:Mike Busch's Manifesto on aircraft maintenance gives the example of a British statistician (Waddington) who studied the problem and instigated the change. Probably applied to US aircraft also.

A very interesting book, that.

I think @zlhglp has correctly identified the story you heard, @Paul_Sengupta. The Chapter on Waddington's work is available on the relevant Amazon UK page, via the "Look Inside" function. Here's a link - click on the book cover image, and go to Chapter 1.
