Testing/verification after maintenance ensures the work done actually restores the system to its required functioning and that there is documented evidence showing it meets safety and performance standards. This step involves checking that the component interfaces, controls, and performance are within spec, and recording the results in the maintenance log so there is traceability for audits and ongoing airworthiness. In short, it confirms the fix works as intended and provides legal and regulatory proof that the task was completed correctly. It isn’t about delaying the task, determining licensing, or repainting components, which cover unrelated areas.
