Which types of inspections are included in the supplemental inspection area?

The correct answer highlights the specific types of inspections included in the supplemental inspection area, which are special, acceptance, and time replacement item inspections.

Special inspections are performed to evaluate the aircraft’s condition, particularly after any major changes that could affect its structural integrity or systems functionality. Acceptance inspections ensure that new or repaired items are functioning properly and meet the required standards before being put into service. Time replacement item inspections focus on components that need to be replaced or serviced after a specific time or usage to maintain safety and operational standards.

The other options refer to different inspection types that do not fall strictly within the supplemental inspection area. Routine and emergency inspections are more general and focus on day-to-day operational readiness, while pre-flight and post-flight inspections are routine checks performed before and after flights to ensure safety and functionality. Structural and system inspections, while critical for aircraft maintenance, are broader categories that encompass both periodic maintenance and checks beyond the defined supplemental area.
