Create discard requirements for life-limited parts

You create discard requirements for LLPs to make sure they are discarded upon expiration. After the component has been destroyed (rendered permanently unrepairable), a certificate of destruction is issued for the LLP, after which its status is set to SCRAP in Maintenix.

To create a requirement to discard LLPs, do the following:

  1. On the Requirement Search page, click Create Requirement.
  2. On the Create Requirement page, provide the required information. Note the following:
    • In the Requirement Type area, select Config Slot.

      It is recommended using Config Slot requirements rather than Part Number requirements because Maintenix cannot include part number requirements in the aircraft's maintenance program.

    • In the Classification area, select Class to be DISCARD (Discard).
    • In the Scheduling Details area, verify that the Recurring check box is not selected.
    • In the Scheduling Details area, select Manufactured Date from the Schedule From: list.
    • In the Planning Details area, make sure the On Condition check box is not selected.
    • In the Planning Details area, make sure the Must Be Removed is selected as Off Parent or Off Wing.
  3. Click OK
    You must now add a scheduling rule to this requirement.
  4. On the details page for the requirement, click the Scheduling tab.
  5. Click Add Scheduling Rule .
  6. On the Add Scheduling Rule page, provide the required information. Note the following:
    • Usage Parm: Select CYCLES (Cycles) or HOURS (Flying Hours).
    • Threshold: Enter the value for life limit of the part. For example, if the LLP is set to expire after 15000 cycles, enter 15000.
    • Deviation (Qty): Enter 0.
    • Sched to Plan Low: Enter 0.
    • Sched to Plan High: Enter 0.
  7. Click OK.
    Note: A discard requirement is not used to remove the inventory item from an assembly, therefore a replacement requirement must also be defined against the configuration slot. This replacement requirement will then be automatically created by Maintenix to uninstall the LLP component, so that the discard requirement can be completed.
