FAA 107 Commercial Drone Pilot Practice Exam

What source of information should be consulted first for maintenance of a small UAS?

1. Other pilots' experiences

2. Manufacturer guidance

3. Online forums

4. FAA regulations

The correct answer is: Manufacturer guidance

When maintaining a small Unmanned Aircraft System (UAS), the first and most authoritative source of information to consult is the manufacturer guidance. This is because the manufacturer provides specific instructions tailored to their product, including maintenance schedules, procedures, required tools, and safety considerations. Following this guidance ensures that the UAS operates as intended and helps in preventing mechanical failures that could arise from improper maintenance. Manufacturer guidance is created with the technical specifications of the aircraft in mind, allowing pilots to adhere to recommended practices designed to preserve the integrity and performance of their equipment. Meanwhile, relying on other source options like pilots' experiences, online forums, or FAA regulations may provide useful insights but typically lack the specificity and reliability of direct manufacturer documentation. Thus, starting with the manufacturer’s guidance ensures the first point of reference is accurate and directly applicable to the UAS being maintained.
