Aircraft Maintenance Course

Lesson 1 • Safety Management Systems in Maintenance

Introduces SMS principles, hazard identification, and risk assessment as applied to maintenance operations. Builds the safety reasoning skills used throughout the course.

Lesson 2 • Aviation Regulatory Framework Overview

Covers the hierarchy of aviation authorities, airworthiness directives, and maintenance regulations. Anchors all subsequent technical work in a compliance-first mindset.

Lesson 3 • Human Factors in Aircraft Maintenance

Examines the Dirty Dozen error model, fatigue effects, and communication breakdowns that cause maintenance incidents. Provides the human-performance lens applied across all practical tasks.

Lesson 1 • Airframe Construction Principles

Covers monocoque, semi-monocoque, and truss structures along with primary load paths. Understanding construction type determines correct inspection and repair approaches.

Lesson 2 • Aircraft Electrical System Basics

Introduces DC and AC bus architecture, circuit protection, and wiring standards. Electrical fundamentals underpin avionics, lighting, and power-system maintenance tasks.

Lesson 3 • Fuel System Architecture

Covers tank types, fuel transfer, venting, and quantity indication. Fuel system knowledge is prerequisite to engine maintenance and fire-safety procedures.

Lesson 4 • Hydraulic and Pneumatic System Overview

Explains hydraulic fluid properties, actuator types, and pneumatic bleed-air applications. These systems power landing gear, brakes, and flight controls covered in later chapters.

Lesson 1 • Aviation Materials and Handling

Covers aluminium alloys, composites, titanium, and approved sealants with storage and handling requirements. Material compatibility prevents corrosion and structural degradation.

Lesson 2 • Precision Measuring Instruments

Teaches use of micrometers, calipers, dial indicators, and bore gauges to aviation tolerances. Measurement accuracy is critical for determining component serviceability.

Lesson 3 • Foreign Object Damage Prevention

Establishes FOD walk procedures, tool accountability, and controlled-area protocols. FOD prevention is a non-negotiable safety practice applied in every maintenance task.

Lesson 4 • Hand Tools and Torque Application

Covers wrench types, screwdrivers, pliers, and torque wrench calibration and use. Proper torque application prevents fastener failure and structural damage.

Lesson 1 • Corrosion Identification and Classification

Classifies corrosion types, rates, and severity levels using manufacturer and regulatory criteria. Correct classification determines whether repair or replacement is required.

Lesson 2 • Scheduled Inspection Programs

Explains phase, letter-check, and on-condition inspection intervals and task card execution. Scheduled programmes ensure systematic coverage of all aircraft zones and systems.

Lesson 3 • Visual Inspection Fundamentals

Teaches systematic visual inspection patterns, lighting techniques, and defect recognition criteria. Visual inspection is the most frequent and foundational maintenance activity.

Lesson 4 • Ultrasonic and Eddy Current Inspection

Introduces pulse-echo ultrasonics and eddy current probe techniques for subsurface flaw detection. These methods are essential for thick structures and hidden corrosion.

Lesson 1 • Sheet Metal Layout and Cutting

Covers bend allowance calculation, layout scribing, and shear and nibbler cutting techniques. Accurate layout prevents material waste and ensures correct part geometry.

Lesson 2 • Structural Repair Manual Interpretation

Teaches navigation of structural repair manuals, damage limits, and allowable repair boundaries. SRM compliance is mandatory before any structural repair begins.

Lesson 3 • Corrosion Treatment and Prevention

Covers mechanical removal, chemical treatment, and protective coating application for corrosion control. Treatment must restore base material and prevent recurrence.

Lesson 4 • Riveting Techniques and Inspection

Trains driven and blind rivet installation, spacing, edge distance, and shop head inspection. Correct riveting restores structural load transfer across repaired panels.

Lesson 1 • Engine Fuel and Induction Systems

Teaches carburetor, fuel injection, and FADEC fuel metering systems and their maintenance. Fuel system faults directly affect engine power output and reliability.

Lesson 2 • Engine Lubrication and Cooling Systems

Covers wet-sump and dry-sump oil systems, oil analysis, and cooling fin and cowling airflow management. Lubrication and cooling failures are leading causes of engine damage.

Lesson 3 • Turbine Engine Fundamentals

Explains compressor, combustion, turbine, and exhaust sections and thermodynamic cycle. Turbine knowledge is prerequisite to borescope inspection and hot-section maintenance.

Lesson 4 • Engine Performance Testing and Troubleshooting

Covers ground run procedures, power checks, and systematic fault isolation using engine parameters. Performance testing validates maintenance actions before return to service.

Lesson 1 • Wiring Diagram Interpretation

Teaches schematic symbols, wire numbering, and tracing circuits through aircraft wiring diagrams. Diagram proficiency is the entry skill for all electrical troubleshooting tasks.

Lesson 2 • Communication and Navigation System Checks

Explains VHF radio, transponder, VOR, ILS, and GPS operational checks and antenna inspection. These checks confirm system accuracy required for instrument flight operations.

Lesson 3 • Electrical Test Equipment and Techniques

Covers multimeter, oscilloscope, and dedicated avionics test set operation for fault isolation. Correct instrument use prevents damage to sensitive avionics components.

Lesson 4 • Wire Repair and Connector Maintenance

Trains splicing, terminal crimping, connector pin insertion, and potting compound application. Proper wire repair prevents intermittent faults and arc-fault hazards.

Lesson 1 • Functional and Operational Testing

Covers system operational checks, rigging verification, and flight control travel measurement after maintenance. Functional testing confirms that maintenance actions achieved the intended result.

Lesson 2 • Post-Maintenance Test Flight Coordination

Covers maintenance test flight request, crew briefing, and in-flight parameter recording requirements. Test flight coordination ensures pilots and maintainers share the same fault-verification objectives.

Lesson 3 • Minimum Equipment List and Deferral Management

Teaches MEL item identification, deferral category intervals, and placard and logbook entry requirements. MEL management keeps aircraft in revenue service within approved airworthiness limits.

Lesson 4 • Maintenance Release Authority and Sign-Off

Explains certifying staff authority, authorised release certificate completion, and dual-inspection requirements. Release authority is a legal responsibility with direct airworthiness consequences.
