Maintenance: Your Responsibility as Pilot
CASR 107 require pilots ensure drone dalam airworthy condition before every flight. This means regular maintenance, systematic inspections, dan proper record-keeping are not optional - they're legal requirements.
Legal Maintenance Requirements
CASR 107 Airworthiness
- Pre-Flight Inspection: Pilot must inspect drone before every flight. See pre-flight checklist.
- Airworthy Condition: Drone must be dalam condition untuk safe flight.
- Maintenance Records: Commercial operators must maintain maintenance logs.
- Pilot Responsibility: Pilot in command responsible untuk airworthiness, cannot delegate.
Maintenance Schedule
Daily Maintenance (Before Every Flight)
- Visual inspection of frame, propellers, motors
- Battery voltage check
- Firmware status verification
- GPS dan sensor calibration check
- Control surface test
Weekly Maintenance (For Regular Users)
- Deep Cleaning: Remove dust, debris dari motors, vents.
- Propeller Inspection: Detailed inspection untuk micro-cracks, warping.
- Motor Bearing Check: Spin motors, listen untuk grinding, roughness.
- Gimbal Calibration: Recalibrate gimbal untuk ensure smooth operation.
- Battery Cycle: Full charge-discharge cycle untuk maintain battery health.
Monthly Maintenance
- Firmware Updates: Check dan install firmware updates.
- Compass Calibration: Full compass calibration.
- IMU Calibration: Recalibrate IMU sensors.
- Screw Tightness: Check all screws, tighten as needed (vibration cause loosening).
- Battery Storage Check: Verify all batteries at proper storage voltage.
Annual Maintenance
- Professional Inspection: Consider professional inspection untuk commercial drones.
- Motor Replacement: Replace motors after 200-300 flight hours.
- ESC Check: Test Electronic Speed Controllers untuk proper function.
- Complete Overhaul: Full disassembly, cleaning, inspection untuk high-use drones.
Component-Specific Maintenance
Propellers
- Inspection: Check before every flight untuk cracks, chips, warping.
- Replacement: Replace immediately jika any damage found.
- Lifespan: Replace after 50-100 flight hours even jika no visible damage (material fatigue).
- Balance: Unbalanced propellers cause vibration, reduce flight time, damage motors.
Motors
- Bearing Wear: Listen untuk grinding sounds (indicate bearing wear).
- Cleaning: Remove dust, debris monthly (prevent overheating).
- Temperature: Motors should not be excessively hot after flight (>70°C indicates problem).
- Replacement: Replace after 200-300 hours atau when bearing wear detected.
Batteries
- Voltage Check: Check cell voltages before every flight.
- Physical Inspection: Check untuk swelling, damage before every use.
- Cycle Tracking: Log charge cycles, retire after 200-300 cycles.
- Storage: Store at 3.8V per cell when not in use. See battery safety.
Gimbal & Camera
- Calibration: Recalibrate monthly atau after hard landing.
- Lens Cleaning: Clean lens weekly (dust affect image quality).
- Gimbal Ribbon Cable: Inspect untuk wear (common failure point).
- Shock Absorption: Check rubber dampeners untuk wear, cracking.
Maintenance Records
Required Documentation
Commercial operators must maintain:
- Flight Logs: Date, time, location, duration of each flight.
- Maintenance Log: All maintenance performed, parts replaced.
- Inspection Records: Pre-flight inspections, periodic inspections.
- Battery Records: Charge cycles, voltage readings, retirement dates.
- Incident Reports: Any crashes, malfunctions, near-misses.
Record Retention
- Minimum Period: Retain records untuk minimum 2 years.
- Digital Records: Use apps (Airdata, DJI FlightHub) untuk automated logging.
- Backup: Keep backup copies (cloud storage recommended).
- Audit Trail: Records may be requested during incident investigation atau regulatory audit.
Preventive Maintenance
Environmental Protection
- Storage: Store dalam cool, dry place. Avoid extreme temperatures.
- Transport: Use proper case untuk transport (prevent damage).
- Moisture Protection: Use silica gel packs dalam storage case.
- Dust Protection: Clean after flying dalam dusty environments.
Operational Practices
- Gentle Flying: Avoid aggressive maneuvers (reduce wear on motors, ESCs).
- Proper Landing: Land gently (hard landings damage gimbal, frame).
- Battery Management: Never deep discharge batteries (reduce lifespan).
- Weather Limits: Respect weather limits (flying dalam bad weather cause damage). See weather assessment.
Troubleshooting Common Issues
Vibration
- Causes: Damaged propellers, unbalanced motors, loose screws.
- Diagnosis: Check propellers first (most common cause).
- Fix: Replace propellers, tighten screws, balance motors.
Reduced Flight Time
- Causes: Battery degradation, motor wear, propeller damage.
- Diagnosis: Check battery voltage sag, motor temperature.
- Fix: Replace batteries, clean/replace motors, replace propellers.
GPS Issues
- Causes: Compass interference, IMU drift, firmware issues.
- Diagnosis: Check compass calibration, IMU status.
- Fix: Recalibrate compass, recalibrate IMU, update firmware.
Professional Maintenance Services
When to Seek Professional Help
- Motor replacement (requires soldering, calibration)
- ESC replacement atau repair
- Flight controller issues
- Gimbal repair (delicate components)
- Crash damage assessment
Choosing Service Provider
- Authorized Service: Use manufacturer-authorized service centers untuk warranty work.
- Experience: Verify technician experience dengan your drone model.
- Turnaround Time: Ask about typical repair times.
- Warranty: Ensure repairs covered by warranty.
Kesimpulan
Regular maintenance adalah investment dalam safety dan equipment longevity. Develop systematic maintenance routine, keep detailed records, dan address issues promptly. Well-maintained drone is safe drone - dan saves money long-term by preventing major failures.
