Final answer:
A Remote Pilot in Command must report a UAS accident to the FAA within 10 calendar days of the operation that led to injury or property damage.
Step-by-step explanation:
The question pertains to the timeframe within which a Remote Pilot in Command (Remote PIC) must report an Unmanned Aircraft System (UAS) accident to the Federal Aviation Administration (FAA). According to FAA guidelines,
in the case of an accident involving a UAS, the Remote PIC is required to report to the FAA within 10 calendar days of the operation that led to the injury or property damage.
This reporting ensures that the agency is informed of serious incidents involving UAS operations, similar to how the Food and Drug Administration (FDA) requires reports of adverse drug experiences after New Drug Application (NDA) approval.
It's important to note that this reporting requirement is specific to UAS accidents and is a regulatory obligation for Remote PICs under FAA rules.
