True or False: After removing the Hi-Lok, it's necessary to inspect the hole with a small hole gauge and micrometer.

After the removal of a Hi-Lok, inspecting the hole with a small hole gauge and a micrometer is essential to ensure the integrity of the structure and the proper fit for any replacement fasteners. This inspection process helps identify any potential damage, wear, or deformation that might have occurred during the fastener's installation or removal.

Using a small hole gauge allows the mechanic to check the diameter of the hole accurately, while the micrometer provides precise measurements to confirm that the hole meets the required specifications. Proper inspection is crucial as it addresses potential issues that could compromise the structural integrity and safety of the aerospace component.

In the case of selection "Depends on the size," and "Only if there's damage," while there may be varying practices based on specific situations or procedures, a thorough inspection after fastener removal is generally a best practice regardless of these conditions. The other option, "False," would imply that no inspection is necessary, which could lead to overlooking critical maintenance steps that ensure the aircraft's safety and performance.
