What markings on an item provides proof that a functional check was done?

The identification of a functional check on an item is crucial for ensuring its reliability and operability. The base maintenance inspector's stamp or signature serves as official documentation that a qualified personnel has completed the necessary assessments and verified that the item meets operational standards. This gives confidence to users or personnel that the equipment can be relied upon for use.

The base maintenance inspector is typically responsible for conducting thorough inspections and certifications on items after maintenance checks. By affixing their stamp or signature, they confirm the completion and validity of the functional check, indicating that the item has been evaluated by someone with appropriate authority and expertise.

Other markings, such as those from a base supply inspector or maintenance point of contact, while valuable for different purposes, do not specifically indicate that a functional check was performed. These might relate more to inspections of supply items or general maintenance communications rather than the explicit verification of operational readiness. The statement "Functional Check Performed" may suggest a functional check has occurred, but it lacks the authoritative backing of a qualified inspector's endorsement, which is provided through the maintenance inspector's markings.
