Operator inspection checks often find normal ___________ items whereas maintenance inspection checks often find deeper level issues.

Operator inspection checks typically focus on routine and visible aspects of the unmanned aircraft system (UAS) to ensure it is functioning correctly and safely for immediate operation. Items checked during these inspections generally relate to the regular wear-and-tear that occurs during standard use, such as checking for obvious signs of damage, proper functioning of basic components, and ensuring that essential systems are operational.

In contrast, maintenance inspections delve deeper into the aircraft's condition. These comprehensive checks are often scheduled at specific intervals and aim to identify underlying issues that may not be evident during routine operator checks. They explore the UAS on a more technical level, looking for issues that could affect long-term performance and safety, such as potential mechanical failures or system malfunctions that arise from extensive use.

This understanding highlights why wear-and-tear items are primarily associated with operator inspections, aligning with the nature of what these inspections are designed to discover.
