What is the only spot that does not get inspected on a daily or turnaround?

The area under the tires is indeed the only spot that typically does not require a daily or turnaround inspection on an aircraft. While general protocols call for thorough inspections of various critical components to ensure safety and operational readiness, the area directly under the tires is not a focus for routine inspections.

Inspections focus on areas that are more likely to show signs of wear, damage, or maintenance needs, such as the fuselage, wings, and cockpit. These areas are crucial for structural integrity and functionality and can reveal issues related to hydraulic systems, electronics, or potential blockages.

The space under the wings and fuselage is significant because it often harbors critical systems, including fuel lines and electrical wiring, which need ongoing checks. The cockpit area is similarly vital, as it houses essential instruments and controls that affect the aircraft's operation. As a result, while all areas of the aircraft are important for overall inspections, under the tires is generally less likely to present immediate issues that would necessitate daily or turnaround inspections.
