About this module
EASA Part 66 Module 9 deals with the human side of maintenance safety: vision and hearing limits, memory, fatigue and shift work, stress and pressure, team communication and shift handover, the classic error models (Murphy's law, the SHELL model, the dirty dozen) and workplace hazards from noise to confined spaces.
It is short and non-technical, but the phrasing of the questions can be subtle — the difference between an error and a violation, or what 'positive measures' means. Practising real question wording is the quickest preparation, and our explanations point at the exact concept each question is probing.
