Unserviceability

Unserviceability refers to the state or condition where a machine, device, component, or system is unable to perform its intended function or to meet specified operational requirements. This can arise from various factors, including mechanical failure, damage, wear and tear, lack of maintenance, improper operation, or design flaws. The term encompasses situations where the item is broken, malfunctioning, or otherwise rendered unusable, hindering its intended use and potentially causing operational disruptions or safety concerns. The assessment of unserviceability often involves determining the extent of the impairment and identifying the underlying cause to facilitate repair or replacement. The degree of unserviceability can range from minor impairment to complete failure.

Unserviceability meaning with examples

• The aircraft's engine exhibited significant unserviceability after experiencing a bird strike during takeoff. The resulting damage to the turbine blades meant that the engine could not generate sufficient thrust for sustained flight, forcing the pilot to abort the flight and return to the airport for repair.
• Due to the extreme wear and tear on the equipment after sustained heavy use in the desert, the robotic exploration rover's navigation system was declared to be in a state of unserviceability. The damaged sensors made the rover's navigation systems unreliable, disrupting plans for deep space operations.
• The vehicle's suspension system demonstrated clear unserviceability. The constant jarring vibrations experienced by the driver and the instability in its ride characteristics suggested a severe failure in the spring components, causing an immediate safety threat to the occupants.
• The failure of the server due to a power surge resulted in the immediate unserviceability of the entire network. Access to critical information and applications was lost until the servers could be repaired and brought back online.
• After a thorough inspection, it was determined that the crane's structural components showed signs of extensive corrosion, leading to its unserviceability. The corrosion compromised the crane's ability to lift and secure heavy loads safely, demanding immediate retirement.
