CHAPTER 1 · EASA Module 9.1
General
Why human factors matter in aviation maintenance - how human error, latent conditions, and Murphy's Law can influence aircraft safety and how technicians can manage the risk.
CHAPTER 2 · EASA Module 9.2
Human Performance and Limitations
The physical and mental capabilities that shape maintenance performance - vision, hearing, information processing, attention, memory, and the challenges of restricted access.
CHAPTER 3 · EASA Module 9.3
Social Psychology
How individual responsibility, team behaviour and organisational culture affect maintenance decisions, motivation, communication and safety leadership.
CHAPTER 4 · EASA Module 9.4
Factors Affecting Performance
The conditions that can raise or reduce human performance in maintenance - health, stress, time pressure, workload, fatigue, shift work, alcohol, medication and drugs.
CHAPTER 5 · EASA Module 9.5
Physical Environment
How the maintenance workplace affects people - noise and fumes, chemicals and solvents, illumination, climate, temperature, motion, vibration and safety culture.
CHAPTER 6 · EASA Module 9.6
Tasks
How to plan and perform maintenance tasks safely by managing resources, physical work, repetitive tasks, visual inspection and complex systems.
CHAPTER 7 · EASA Module 9.7
Communication
The communication methods that keep maintenance work coordinated - speech, documents, non-verbal cues, team communication, shift handovers, work logging and dissemination of information.
CHAPTER 8 · EASA Module 9.8
Human Error
Why maintenance errors occur, how error models explain them, how errors can remain latent, and how reporting, checking and error-management strategies reduce their consequences.
CHAPTER 9 · EASA Module 9.9
Hazards in the Workplace
How to recognise, assess and control workplace hazards in aviation maintenance, and how to prepare for emergencies when hazards cannot be completely removed.
