serviceable

Serviceable is an adjective that describes something capable of being used or kept in service. It implies that an item can perform its intended function without requiring replacement, often after repair or refurbishment, rather than being new or in pristine condition. The term focuses on operability and usefulness rather than novelty.

In maintenance and reliability contexts, a serviceable part is one that can be repaired or restored to usable condition. A component may be deemed unserviceable if it cannot be repaired economically, is excessively worn, or fails safety checks. Serviceability is also used as a broader concept referring to how easily a system can be maintained, repaired, or kept operational, including factors such as accessibility, spare parts availability, and maintenance procedures.

Industry usage, particularly in aviation, maritime, and heavy equipment, commonly distinguishes serviceable from unserviceable items. Components that meet inspection and certification requirements are tagged serviceable and can be issued for use. Items that fail inspections are marked unserviceable and scheduled for repair, overhaul, or disposal. Serviceability records help manage inventory, predict downtime, and assess readiness and safety.

In everyday language, calling an object serviceable simply means it is usable and safe to operate, not necessarily new. The term is widely used in engineering, procurement, and maintenance workflows to signal that something can continue to function with appropriate care. The opposite is unserviceable or beyond economical repair.
