Who grants release for service after maintenance meets TO 00-20-1 requirements?

• A. Technician.
• B. Supervisor.
• C. Quality Assurance.
• D. Maintenance dispatcher.

Answer: (C)

Release for service after maintenance is granted by Quality Assurance because this function provides the independent verification that the work was completed correctly, per TO 00-20-1 procedures, and that all documentation, tests, and safety checks are in place before the aircraft or equipment is returned to operational status. QA reviews the maintenance records, confirms all required steps were followed, verifies any open items are resolved, and signs off to authorize the service release. Technicians perform the work, supervisors oversee the process, and dispatch handles timing and movement, but the formal authorization to return to service rests with Quality Assurance to ensure objective compliance and safety.
