Tēnā koe,

Today’s English Tips will discuss “The Dirty Dozen”, which refers to twelve common human error preconditions that can lead to accidents or incidents. Developed by Gordon Dupont in 1993, it has become a cornerstone of Human Factors in Maintenance training courses worldwide.

The Dirty Dozen includes:

  • lack of communication
  • distraction
  • lack of resources
  • stress, complacency
  • lack of teamwork
  • pressure
  • lack of awareness
  • lack of knowledge
  • fatigue
  • lack of assertiveness
  • norms. 

Understanding these elements is crucial to prevent accidents or incidents in various businesses, organizations, and workplaces.

To reduce the possibility of human error causing problems, there are countermeasures designed for each element on the Dirty Dozen list.

It is vital to focus attention and resources on reducing and capturing human error to ensure safety in all areas of the aviation industry, not just aircraft maintenance.
