Which of the following scenarios requires immediate notification to the FAA?

Immediate notification to the FAA is required in the event of a flight crew member illness because it directly impacts flight safety. The FAA has regulations in place to ensure that flight crews are fit for duty and able to operate an aircraft safely. If a crew member becomes ill, it is critical that the FAA is informed so that necessary measures can be taken, such as substituting crew members or altering flight operations to comply with safety standards.

Scheduled maintenance procedures, while important, are typically planned and do not require immediate notification unless they pose a safety risk. Pre-flight inspection issues may require attention and could lead to a delay or adjustment in operations, but unless they are critical and affect safety or airworthiness directly, they do not necessitate immediate FAA notification. Routine flight delays are a normal part of aviation operations and do not usually require any notification to the FAA unless they extend significantly or impact air traffic control operations.

In contrast, the scenario involving crew member illness highlights the need for swift communication with regulatory authorities to maintain safety protocols, ensuring that all operational procedures are adhered to without compromise.
