FAA 107 Commercial Drone Pilot Practice Exam

Regular inspections and upkeep according to manufacturer specifications is essential for maintaining a small Unmanned Aircraft System (UAS). This approach ensures that the UAS operates safely and efficiently, as it addresses potential wear and tear that can occur with routine use. Following the manufacturer's guidelines is crucial because these specifications are crafted based on extensive testing and expert knowledge about the specific UAS model, ensuring that any maintenance procedures are appropriate and effective.

Engaging in regular inspections helps in identifying issues before they become significant problems, thereby enhancing safety and reliability. This proactive strategy not only extends the life of the drone but also helps in complying with regulatory requirements that often stipulate regular maintenance schedules.

Other options, such as performing periodic complete overhauls only or only conducting maintenance when problems arise, would result in neglecting routine issues that could compromise safety and functionality. Daily cleaning and oiling of all moving parts, while important in specific contexts, is not generally required for all UAS and may not even apply to models that do not have moving parts needing such frequent maintenance. Adhering to manufacturer specifications provides a balanced approach to keeping the small UAS in optimal working condition.
