What does the term "RFI" stand for in aviation maintenance?

In aviation maintenance, the term "RFI" stands for "Ready For Issue." This designation indicates that an item, component, or system has been completed and is prepared to be put into operational use, whether that's for flight or ground operations. It signifies that all necessary maintenance, checks, and inspections have been performed, ensuring that the item meets all standards for safety and functionality before being issued or deployed.

The other terms listed, while similar, do not accurately represent what "RFI" stands for in this context. "Ready For Inspection" might suggest that an item is awaiting evaluation or review, but it doesn't convey the readiness status for operational use. "Routine Flight Inspection" refers to regular assessments conducted on aircraft to ensure ongoing airworthiness, which is distinct from the RFI status. Thus, "Ready For Issue" correctly encapsulates the intent of RFI in aviation maintenance, focusing on the operational readiness of items or equipment.
