Maintenance & Preflight Inspection

Part 107 requires the remote pilot in command to ensure the small UAS is in a condition for safe operation before every flight. This is a legal duty — not a suggestion. If the aircraft is not airworthy, it cannot legally fly.

• "Condition for safe operation" means the aircraft is free of defects that could affect safe flight.
• This includes physical condition, firmware status, battery health, and configuration.
• The FAA can ask: 'How did you determine the aircraft was safe to fly?' Have an answer.
• If you discover a defect during inspection, document it and ground the aircraft until resolved.
