What are the main types of maintenance conducted on the F/A-18 E/F?

The correct choice identifies the main types of maintenance as preventive and corrective maintenance. Preventive maintenance is essential as it involves regular checks and actions taken to prevent failures. This type of maintenance ensures that the F/A-18 E/F remains operational and safe, reducing the likelihood of issues that could arise from wear and tear or neglect.

Corrective maintenance comes into play when a malfunction occurs, addressing and repairing the specific failure once it has been detected. This reactive approach is critical for maintaining aircraft functionality and safety, allowing for timely fixes to issues that could impact flight operations.

While routine and emergency maintenance could seem plausible, they represent operational paradigms rather than the primary maintenance categories. Scheduled and unscheduled maintenance also relate, but they typically refer more to when maintenance is planned rather than the nature of the work itself. Advanced and basic maintenance do not accurately categorize the primary maintenance types for the F/A-18 E/F. Thus, the distinction between preventive and corrective maintenance provides a clear framework for understanding the overall maintenance strategy for this aircraft.
