If a leak exists in the primary servo and no action is taken, which component is lost?

• A. Backup Pump
• B. Hydraulic Reservoir
• C. Engine Oil
• D. Electrical Power

Answer: (A)

When a helicopter’s flight-control system relies on hydraulics, a primary servo is a hydraulic actuator that moves a control surface under pressure, with a backup pump providing pressure if the main path becomes unavailable. If there’s a leak in the primary servo and no action is taken, hydraulic fluid is lost from that circuit, and pressure cannot be maintained. The backup pump is the component that would be lost because it is the source of hydraulic power that would need to take over, but the ongoing leak causes fluid depletion and pressure collapse in the system. The hydraulic reservoir simply stores fluid and isn’t inherently lost by a servo leak, engine oil is a separate fluid, and electrical power isn’t directly the casualty of a hydraulic leak in the primary servo.
