Final answer:
When an sUAS manufacturer doesn't provide scheduled maintenance information, the operator should create their own maintenance protocol to ensure safety and proper functioning of the aircraft.
Step-by-step explanation:
If the manufacturer of an sUAS (small Unmanned Aircraft System) does not provide information about scheduled maintenance, the appropriate action for the operator to take is to establish a scheduled maintenance protocol. This involves the operator creating their own maintenance schedule based on general industry standards, usage frequency, and the operational environment of the sUAS. It is vital to ensure that all components are regularly checked and maintained to reduce the risk of malfunctions or failures that could compromise safety during flight operations.
