General Questions for All Pilots

1. What maintenance checks should I perform before every flight?
Always inspect your drone for physical damage, loose components, and battery issues before flying. Verify propellers are undamaged and securely attached, ensure firmware is up to date, and confirm sensors are clean and functional. Regular pre-flight checks are essential to prevent in-flight malfunctions.

Safety Reminder: Conducting a thorough pre-flight inspection reduces the risk of crashes or regulatory violations.

---

2. Does EASA require drones to undergo periodic inspections?
Yes, EASA requires drones to be maintained and inspected according to manufacturer guidelines to ensure airworthiness and safe operation. Operators must follow maintenance schedules specified in the drone manual and keep records of all inspections and repairs performed (Reg 2019/947 Art. 4).

---

3. How do I document maintenance and inspections for compliance?
Maintain a logbook or digital record for your drone. Include details of each inspection, repairs performed, software updates, and battery health checks. These records should be easily accessible in case of an audit or incident (Reg 2019/947 Art. 4).

---

4. What happens if I fail to maintain my drone properly?
Failure to maintain your drone as per manufacturer guidelines could result in unsafe flight conditions, legal penalties, or invalidation of your operational permissions. Regular maintenance is both a safety and compliance requirement (Reg 2019/947 Art. 4).

Questions for Beginners

5. How do I know if my drone needs repairs? Check for common issues such as:

• ▸
  Cracks or damage to the frame or propellers
• ▸
  Unusual noises during flight
• ▸
  Reduced battery performance
• ▸
  Malfunctioning sensors or GPS

If you notice any of these issues, refrain from flying until repairs are completed. Always consult the manufacturer’s manual for troubleshooting and repair guidance.

---

6. Can I repair my drone myself, or should I use a professional service?
Minor repairs, such as replacing propellers or cleaning sensors, can often be done by the operator. For more complex issues, such as motor or circuit board damage, use a certified repair service to ensure compliance with EASA safety standards (Reg 2019/947 Art. 4).

Questions for Active Pilots

7. How do I maintain my drone’s batteries for longer life?

• ▸
  Store batteries in a cool, dry place.
• ▸
  Avoid overcharging or fully discharging them.
• ▸
  Check for swelling or damage regularly.
• ▸
  Follow manufacturer instructions for charging and storage.

Proper battery maintenance ensures safe flights and avoids mid-air power failures.

---

8. What if my drone experiences a malfunction during flight?
Immediately execute emergency procedures, such as returning to the home point or landing safely. Afterward, inspect the drone thoroughly, identify the cause of the malfunction, and perform necessary repairs before flying again. Always report incidents to authorities if required (Reg 2019/947 Art. 19).

Questions for Professional Operators

9. Do commercial drones require additional maintenance procedures? Yes, commercial drones often require more rigorous inspections and adherence to detailed maintenance schedules outlined in the manufacturer's instructions. Operators must ensure compliance with specific regulations for commercial operations (Reg 2019/947 Art. 6).

---

10. How do I prepare for an EASA compliance audit related to drone maintenance? Ensure your maintenance records are complete, accurate, and accessible. Include details such as:

• ▸
  Dates of inspections and repairs
• ▸
  Firmware updates
• ▸
  Battery health logs
• ▸
  Evidence of adherence to manufacturer instructions

A well-maintained log demonstrates your commitment to safety and compliance (Reg 2019/947 Art. 4).

---

Advanced Questions

11. What are the maintenance requirements for drones operating in the “specific” category? Drones in the “specific” category must follow manufacturer-prescribed maintenance and inspection protocols. Operators may also need to implement additional procedures based on the risk assessment submitted for operational authorization (Reg 2019/947 Art. 5).

---

12. How do I ensure compliance when flying near airports or critical infrastructure?

• ▸
  Perform thorough pre-flight inspections to ensure drone reliability.
• ▸
  Verify the drone's GPS and sensors function correctly for precise navigation.
• ▸
  Maintain detailed maintenance records to demonstrate airworthiness during authorization requests (Reg 2019/947 Art. 15).

---

Critical Safety and Legal Compliance Questions

13. What are the consequences of flying a poorly maintained drone? Flying a drone with unresolved maintenance issues can result in:

• ▸
  Loss of control or crashes
• ▸
  Regulatory penalties
• ▸
  Revocation of operational permissions
• ▸
  Potential harm to people or property

Prioritize regular inspections and repairs to avoid these risks (Reg 2019/947 Art. 4).

---

14. Can I use third-party parts for repairs?
Third-party parts may be used if they meet manufacturer specifications and do not compromise safety or airworthiness. However, using uncertified parts could invalidate your operational permissions or insurance coverage (Reg 2019/947 Art. 4).

---

15. How often should I update my drone firmware?
Update firmware as soon as new versions are released by the manufacturer. Firmware updates often include critical improvements for safety, performance, and compliance with changing regulations.
