Drone Maintenance Technician Course

Lesson 1 • Personal Protective Equipment

Defines required PPE for electrical, mechanical, and chemical tasks. Directly reduces injury risk in all subsequent lab sessions.

Lesson 2 • Workshop Organisation and FOD Control

Teaches 5S methodology and foreign object debris prevention in a maintenance environment. Reduces errors and rework caused by disorganised workspaces.

Lesson 3 • Tool and Equipment Safety

Establishes correct use of hand tools, soldering irons, and power equipment. Ensures learners handle tools safely before performing repairs.

Lesson 4 • Electrical Safety Fundamentals

Covers lockout/tagout procedures, safe battery handling, and arc-flash awareness. Prevents electrical incidents during disassembly and bench testing.

Lesson 1 • Flight Control and Sensor Overview

Introduces flight controllers, IMUs, GPS modules, and barometers. Sets the context for avionics diagnostics covered in later chapters.

Lesson 2 • Power Systems and Energy Storage

Covers battery chemistry, capacity ratings, and power distribution boards. Establishes safe energy-handling practices used in every subsequent lab activity.

Lesson 3 • Drone Types and Configurations

Covers fixed-wing, multirotor, and hybrid platforms with their structural differences. Provides the classification framework used throughout the course.

Lesson 4 • Core Airframe Components

Identifies frames, arms, landing gear, and mounting systems. Connects physical structure to load distribution and maintenance access points.

Lesson 1 • Hand Tools for Drone Maintenance

Covers hex drivers, nut drivers, spanner wrenches, and precision screwdrivers specific to drone hardware. Correct tool selection prevents fastener and component damage.

Lesson 2 • Maintenance Records and Logbooks

Establishes procedures for logging inspections, repairs, and component life cycles. Accurate records support airworthiness compliance and fleet management.

Lesson 3 • Soldering and Rework Equipment

Covers soldering stations, hot-air rework tools, and desoldering equipment. Builds the soldering skills applied in motor, ESC, and wiring repairs.

Lesson 4 • Technical Documentation and Schematics

Teaches interpretation of wiring diagrams, exploded-view drawings, and manufacturer service manuals. Documentation literacy is essential for accurate fault diagnosis.

Lesson 1 • Composite and Plastic Frame Repair

Teaches epoxy patching, carbon fibre layup repair, and plastic welding techniques. Restores structural integrity while maintaining weight targets.

Lesson 2 • Landing Gear and Mount Servicing

Covers inspection, adjustment, and replacement of landing gear legs, dampers, and payload mounts. Proper servicing protects sensors and payloads on landing.

Lesson 3 • Fastener and Hardware Management

Addresses thread-locking compounds, fastener grades, and replacement standards for drone hardware. Correct fastener management prevents in-flight structural failures.

Lesson 4 • Pre-Flight and Post-Flight Inspections

Defines structured inspection checklists for airframe, propulsion, and avionics. Systematic inspection habits prevent in-flight failures.

Lesson 1 • Brushless Motor Inspection and Testing

Covers bearing inspection, winding resistance measurement, and no-load current testing. Identifies motor faults before they cause in-flight failures.

Lesson 2 • ESC Inspection and Configuration

Addresses ESC heat damage, solder joint inspection, and firmware configuration. Correct ESC setup ensures smooth motor control and prevents thermal failures.

Lesson 3 • Propeller Inspection and Balancing

Covers crack detection, tip erosion assessment, and static balancing of propellers. Balanced propellers reduce vibration and extend motor bearing life.

Lesson 4 • Motor Disassembly and Cleaning

Teaches safe motor disassembly, bearing replacement, and cleaning procedures. Extends motor service life and restores rated performance.

Lesson 1 • Power Distribution System Service

Covers PDB inspection, voltage regulator testing, and BEC output verification. Stable power distribution prevents avionics brownouts and resets in flight.

Lesson 2 • Communication and Telemetry Systems

Covers RC receiver binding, telemetry link testing, and antenna inspection. Reliable communication links are essential for safe remote operation.

Lesson 3 • Wiring Harness Inspection and Repair

Covers continuity testing, insulation damage detection, and wire repair techniques. Reliable wiring is the foundation of all avionics and propulsion function.

Lesson 4 • Battery System Maintenance

Teaches cell balance checking, capacity testing, and connector replacement for flight batteries. Proper battery maintenance directly affects flight time and safety.

Lesson 1 • Payload Interface and Power Wiring

Addresses payload connector standards, power filtering, and data interface wiring. Correct payload wiring prevents interference with flight control systems.

Lesson 2 • Sensor Calibration and Verification

Covers end-to-end sensor calibration workflows and output verification against known references. Calibrated sensors ensure mission data meets accuracy requirements.

Lesson 3 • LiDAR and Ultrasonic Sensor Service

Covers window cleaning, alignment verification, and output signal testing for ranging sensors. Accurate ranging sensors are critical for terrain-following and obstacle avoidance.

Lesson 4 • Gimbal Calibration and Tuning

Teaches IMU calibration, PID tuning, and horizon levelling for stabilised gimbals. Proper tuning eliminates jello effect and horizon drift in footage.

Lesson 1 • Intermittent and Environmental Faults

Addresses moisture ingress, thermal cycling damage, and vibration-induced connector failures. Environmental faults require specialised detection and repair strategies.

Lesson 2 • Multi-System Fault Scenarios

Presents complex fault cases involving simultaneous propulsion, electrical, and avionics issues. Develops the diagnostic reasoning needed for real-world maintenance challenges.

Lesson 3 • Post-Repair Verification and Test Flight

Defines bench test sequences, ground run procedures, and supervised test flight protocols. Verification confirms that repairs are complete and the drone is airworthy.

Lesson 4 • Flight Log Analysis for Fault Finding

Covers extraction, visualisation, and interpretation of onboard flight logs. Log data reveals intermittent faults invisible during bench testing.
