A planned temporary shutdown of a system for routine inspection, testing, and maintenance, conducted under constant attendance of qualified personnel and with the ability to restore service quickly, should be considered which type of deficiency or impairment?

• A. Emergency impairment
• B. Non-Critical deficiency
• C. Pre planned Impairment
• D. This is not an impairment

Answer: (D)

Planned maintenance performed under clear controls is considered a normal, controlled activity rather than an impairment. The key idea is that the shutdown is scheduled, monitored by qualified personnel, and designed to allow quick restoration of service. Because safety is actively managed, the downtime does not represent a degrading deficiency in the system’s ability to operate—it’s a deliberate, temporary interruption intended to prevent future issues. In this context, it isn’t classified as an impairment.
