Module 6 Materials and Hardware
Ferrous and non-ferrous materials, composites, corrosion, fasteners, pipes, bearings, transmissions and control cables.
How to prepare for UK Part-66 basic-knowledge examinations
Fix the intended A, B1, B2, B2L, B3, L or C route; use the regulatory module matrix and knowledge levels; then rehearse the exact MCQ and essay components that apply to each selected module.
Core concepts
Concept 1
Material properties, heat treatment, fatigue and corrosion determine serviceability and the permitted repair process.
Exam cue: Identify material and specification before selecting a process or replacement.
Concept 2
Fasteners, locking devices, bearings, gears, cables, pipes and unions must be identified, installed and inspected to the approved standard.
Exam cue: Use the approved torque, locking, orientation and inspection criteria.
Concept 3
Composite structure requires material-specific damage detection, environmental control and repair methods.
Exam cue: Treat hidden damage and corrosion extent as an engineering assessment problem.
Risk pitfalls and guardrails
Substituting a visually similar fastener.
Guardrail: Do not mix Category A, B1, B2/B2L, B3 or Category L module variants, or treat the aggregate 601-item study allocation as an official CAA examination total.
Removing corrosion without checking remaining thickness or approved limits.
Guardrail: Do not mix Category A, B1, B2/B2L, B3 or Category L module variants, or treat the aggregate 601-item study allocation as an official CAA examination total.
Using metal-structure repair assumptions on composites.
Guardrail: Do not mix Category A, B1, B2/B2L, B3 or Category L module variants, or treat the aggregate 601-item study allocation as an official CAA examination total.
Memory anchors
Identify
Confirm material, part and specification before work.
Corrosion
Find the type, cause, extent and approved treatment.
Fastener
Correct part, fit, torque and locking are all required.
Bearing
Inspect condition, lubrication, fit and security.
Composite
Control contamination, temperature, lay-up and cure using approved data.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
Knowledge Check (after reading)
Short check-up to confirm understanding of this module.
