Additional information for completing the LORA effort.
1. The first step in the process is to develop a LORA candidate list; initial candidate list shall all include repairable item/components, a copy of this list shall be provided to the government.
1. The initial candidate list shall include all repairable item/components, when analyzed if they are determined not to be viable LORA candidates. These components will be annotated as not applicable (N/A).
1. Levels of Maintenance – For the purpose of this effort the following levels shall be used Field Maintenance (DS), Sustainment Maintenance (DEPOT and Contractor).
1. Remove/Replace and Repair Time - The current commercial repair/replace times will be used. If times are not available, times shall be estimated using MIL-HDBK-470A.
1. Failure Rates – The current commercial failure rates will be used for the initial/baseline results. The failure rates shall be increased as stated elsewhere in this attachment.
1. Unknown DATA - Elements that do not have current or know data shall use historical data for that item/component or a like item/component; data shall be either commercial or military.
1. Special Tools – All individual Special Tools needed for repair tasks shall be added under Support Equipment. Support Equipment shall be incorporated in each evaluation.
1. All data shall be entered in COMPASS and be as complete as possible, this is to ensure that the evaluations are correct as possible.
