Performed Description
Organizational On the product at the customer’s operational or product site
Normally is limited to periodic performance checks, visual inspections, cleaning, limited servicing, adjustments, and removal and replacement of some components (i.e., constituent module, part, item, etc., of the product). Repair of removed components is normally not made at this level. Instead, the failed component is replaced with a spare. The removed component is then sent to the next level of maintenance (usually intermediate) for repair. Diagnostics, accessibility, and ease of removal and replacement are very important and should be key design considerations. At this level, the primary goals are keeping the product in a serviceable condition and rapidly restoring the product to an operable condition after failure using low-to-moderate skilled personnel.
