Component codes

A component code identifies an assembly, subassembly, or item that someone can do maintenance work on. Component codes are in multiple applications, including work orders, purchase orders, and job plans.

You can organize component codes into hierarchies, in which parent component codes have one or more child component codes. Child components can also have their own child components. To create component code hierarchies, you specify parent and child component codes in the Component Codes (Tr) application.

To view component code hierarchies, click Open Drilldown in the Component Codes (Tr) application or on the Detail menu of a Component Code, ATA Code, or Belongs To field. In the Component Codes Drilldown window, you can browse the hierarchy and select a component code for the field.

Component codes can be associated with position codes. For example, some brake assembly components are specific to either the left or right of the aircraft.

You can delete a component code only if no active records reference the code. A component code can be referenced as the parent of another component code, or referenced by other records such as work orders and purchase orders.
