The Dirty Dozen of Human Factors (alternatively known as Dirty Dozen in Aviation or, simply, the Dirty Dozen; hereinafter, the Dozen) is the twelve most common maintenance-related human factors that are responsible for the most of incidents and accidents in aviation. The Dozen was initially developed by Transport Canada.
Definitions
According to the FAA AC 120-72,
- Dirty Dozen. The twelve most common maintenance-related causes of errors. These twelve causes are: (a) lack of communication, (b) complacency. (c) lack of knowledge, (d) distraction, (e) lack of teamwork, (f) fatigue, (g) lack of resources, (h) pressure, (i) lack of assertiveness, (j) stress, (k) lack of awareness, (l) norms.
In maintenance
According to the FAA AMT Handbook,
- Due to a large number of maintenance-related aviation accidents and incidents that occurred in the late 1980s and early 1990s, Transport Canada identified twelve human factors that degrade people's ability to perform effectively and safely, which could lead to maintenance errors. These twelve factors, known as the "dirty dozen," were eventually adopted by the aviation industry as a straight forward means to discuss human error in maintenance. It is important to know the dirty dozen, how to recognize their symptoms, and most importantly, know how to avoid or contain errors produced by the dirty dozen. Understanding the interaction between organizational, work group, and individual factors that may lead to errors and accidents, aircraft maintenance technicians can learn to prevent or manage them proactively in the future.
Components
These twelve causes are: (a) lack of communication, (b) complacency. (c) lack of knowledge, (d) distraction, (e) lack of teamwork, (f) fatigue, (g) lack of resources, (h) pressure, (i) lack of assertiveness, (j) stress, (k) lack of awareness, (l) norms.
