Core concepts
Concept 1
Maintenance practice combines safe working, correct tools and calibration, drawings, standards, inspection and disciplined use of approved data.
Exam cue: Stop when the task, data, tooling or competence is unclear.
Concept 2
Aircraft handling, storage, weighing, jacking, towing, cleaning and environmental protection require aircraft-specific procedures and risk controls.
Exam cue: Record the actual work, measurements, parts and independent inspections required.
Concept 3
The Module 7 examination includes two essays as well as MCQs; each essay is a separate 20-minute assessment against key points.
Exam cue: Structure an essay around the complete safe maintenance process, not disconnected keywords.
