Why it is a regulatory topic
Human factors are part of Part-66 basic knowledge (module 9) and of the initial and continuation training required for Part-145 organisation staff.
The Dirty Dozen
A list of twelve contributing factors to error, widely used in maintenance human factors training:
- Lack of communication
- Complacency
- Lack of knowledge
- Distraction
- Lack of teamwork
- Fatigue
- Lack of resources
- Pressure
- Lack of assertiveness
- Stress
- Lack of awareness
- Norms (non-compliant practices that became habit)
Useful reflexes
- Work from current maintenance data, never from memory.
- Stop and report when in doubt, interrupted or fatigued.
- Use the organisation's occurrence reporting system.
