'Bridging the gap between system safety theory and practice, this book provides a clear, comprehensive, field-tested framework to assist aviation safety professionals with investigating, analyzing, and assessing the impact of human error in aviation accidents and incidents. A 'must-read' for all interested in causal factor analysis!' Dr. James T. LuxhAj, Rutgers University, USA '...it is the training in human error analysis using HFACS that has enabled our Naval Flight Surgeons to serve as the human factors experts...' Captain James R. Fraser, M.D., Command Surgeon, Naval Safety Center, Norfolk, Virginia. 'This book is essential reading for all safety professionals, investigators and analysts. Time tested results of aircraft mishap analysis reveal that 80% of all mishaps have human factors as a significant contributing causal factor. These diverse factors have been identified but until now have been difficult to classify in a simple schema that could be used by operators, investigators or human error professionals. This sentinel work, that Dr's Wiegmann and Shappell have generated based upon Reason's model for human error, now provides an elegant tool for not only analysis and classification of the disparate data elements but also provides a frame work to build our intervention strategies around.' Captain Nicholas Webster, MD, MPH, Aeromedical Safety Professional '...the book should be required reading for any journalist expected to cover air accidents. ...it contains a wealth of insight and it will be a useful addition to the bookshelf of anyone with an interest in aviation safety. ' Navigation News Jan 04 'This is a seriously informative and provocative text which deserves a wide readership among all aviation safety professionals and concerned individuals and organisations in the military forces and general travelling public.'
