Part-66 Module 9 study plan
Part-66 Module 9 · Give each week a clear focus.
8 weeks · About 7 hours per week
Hazards in the Workplace & General
Define hazard, risk and risk assessment and distinguish between the three in writing
Classify workplace hazards into physical, chemical, biological, ergonomic and psychosocial groups with two aviation-maintenance examples for each
Identify the recurring maintenance workplace hazards: noise, fuel and solvent vapours, hydraulic fluid, composite dust, moving machinery, electrical supply and work at height
Describe the purpose and typical stages of a hazard-reporting and safety-management process
Map the nine Module 9 domains and their weightings against your own current confidence
Your checkpoint
One-page hazard classification table with at least 20 original examples, plus a self-marked 15-question quiz on 9.9 and 9.1 scored at 80% or above
Human Performance and Limitations & Human Error
Explain the human information processing chain (perception, attention, memory, decision, response) and redraw the diagram from memory
Describe the limits of vision, hearing, memory capacity and attention span, and state how each degrades under workload
Define human error and distinguish slips, lapses, mistakes and violations using maintenance-specific examples
Map each element of the Dirty Dozen to the domain it belongs to and give one countermeasure per element
Your checkpoint
An error-taxonomy sheet containing three original maintenance scenarios for each error type, each classified with a written justification
Social Psychology & Communication
Explain how group norms, roles, peer pressure and 'everyone signs it off' culture influence individual maintenance decisions
Describe assertiveness, conflict resolution and the responsibilities of the team leader or supervisor
Identify barriers to verbal, written and non-verbal communication and predict the maintenance consequence of each
Describe correct communication protocols for logbook entries, task cards, verbal handover and read-back
Your checkpoint
A written model shift-handover transcript plus a critique identifying five communication failures in a deliberately flawed version and the correction for each
Factors Affecting Performance & Tasks
Explain how fitness, fatigue, stress, alcohol and drugs, and motivation affect performance, and state the countermeasure for each
Describe circadian-rhythm effects and quantify the error risk of night-shift and early-start working patterns
Decompose a typical maintenance task into ordered steps and flag the steps where error is most likely
Explain how task complexity, time pressure and repetitive work change error probability
Your checkpoint
A from-memory task analysis of a component replacement listing every step in sequence and marking the five highest-error-risk steps with reasons
Physical Environment
Describe the effects of noise and vibration on hearing and on task performance, and state the protective measures
Explain how temperature, humidity, air quality and lighting alter performance and error rate
Explain how work at height, confined spaces and moving machinery change the way a task is carried out
Describe the effect of illumination and glare on visual inspection tasks
Your checkpoint
A physical-environment risk table covering 10 scenarios, each with hazard, effect on performance and control measure
Hazards in the Workplace & Human Error & Human Performance and Limitations & General & Social Psychology & Communication & Factors Affecting Performance & Tasks & Physical Environment
Rank your own confidence in all nine domains and identify the two weakest
Re-work every question missed in the week-4 practice paper without notes until all are correct
Condense 30 key definitions and lists into a spaced-repetition flashcard set and run three sessions
Complete a 40-question mixed paper spanning all nine domains
Your checkpoint
A personal confidence ranking table across the nine domains plus a 40-question mixed paper scored at 80% or above
Hazards in the Workplace & Human Error & Human Performance and Limitations & Factors Affecting Performance & Physical Environment & Social Psychology & Communication & Tasks & General
Sit a full-length timed mock examination under strict exam conditions
Tag every incorrect answer to its domain and identify the repeating failure pattern
Re-study the two lowest-scoring domains with focused notes and a fresh question set
Compile a one-page sheet of the traps and distractors you personally fall for
Your checkpoint
A completed full-length mock scored at 85% or above, with an error-tagging spreadsheet showing domain, cause and corrective action per miss
Hazards in the Workplace & Human Error & Human Performance and Limitations & Factors Affecting Performance & Physical Environment & Social Psychology & Communication & Tasks & General
Re-sit a second full-length mock and compare the score against week 7
Recite from memory the Dirty Dozen, the error-type taxonomy, the hazard classes and the communication barriers in under ten minutes
Review the error-traps sheet and the flashcard set one final time
Plan sleep, travel and fatigue management for exam day
Your checkpoint
A second full-length mock scored at 90% or above plus a one-page exam-day readiness checklist
Milestones
Week 2: Explain the information-processing chain and the Dirty Dozen aloud, unaided, in under five minutes; if any element is missed, re-drill before starting week 3
Week 4: Score 75% or above on a 30-question paper drawn from 9.1, 9.2, 9.8 and 9.9, with every miss logged by domain
Week 6: Score 80% or above on the 40-question mixed paper and confirm that no domain ranks below 'moderate confidence' on the self-ranking table
Week 7: Score 85% or above on a full-length timed mock, with no single domain below 70%
Week 8: Score 90% or above on the final full-length mock and complete the exam-day checklist
