The chapter "A Human Error Approach to Aviation Accident Analysis" in the book "A Human Error Approach to Aviation Accident Analysis: The Human Factors Analysis and Classification System" by Douglas A. Wiegmann and Scott A. Shappell discusses the increasing role of human error in aviation accidents as aircraft have become more reliable. The authors highlight that while mechanical and environmental factors have contributed to a significant reduction in accidents, human error remains a critical issue. They argue that traditional accident investigation methods, which are primarily engineering-focused, have not been as effective in addressing human error. In contrast, the Human Factors Analysis and Classification System (HFACS) is presented as a comprehensive framework that bridges the gap between theory and practice, helping to improve the quality and quantity of information gathered during accident investigations. The chapter also includes case studies and examples to illustrate how HFACS can be applied to real-world aviation accidents, emphasizing its utility in identifying and addressing human causal factors.The chapter "A Human Error Approach to Aviation Accident Analysis" in the book "A Human Error Approach to Aviation Accident Analysis: The Human Factors Analysis and Classification System" by Douglas A.
