I’ve been involved in aerial sports for quite a few years and every aircraft that I’ve had anything to do with – powered or unpowered - requires scheduled maintenance to ensure that it will keep flying. What about drones? Do we keep flying them until they drop out of the sky? Is there a recommended maintenance schedule? If so, who does it? I know the stakes are not as high as for passenger carrying aircraft, but the consequences of even a single engine failure are catastrophic – i.e. total loss of aircraft – and high possibility of damage to persons or property.
