About this file
This document contains an attachment providing guidance for completing a Level of Repair Analysis (LORA) as well as details of a solicitation for Type I Family of All-Terrain Cranes. The attachment outlines the LORA candidate list development process and specifies data elements required for input into the COMPASS model. It defines levels of maintenance and provides directions for determining repair times, failure rates, and incorporating special tools and support equipment evaluations. A non-economic evaluation, economic evaluation, and sensitivity and trend analyses adjusting MTBF, operating hours, and MTTR values plus maintenance policies are to be completed.
The solicitation seeks proposals for 265 Type I Family of All-Terrain Cranes, three first article test units, ancillary services, and logistics data development. The requirement is for commercial items with minor military modifications. The contract type will be firm-fixed-price for a six-year period including three base and three option years. Proposals are due by March 17, 2021 for this competitive solicitation issued by the Department of the Army Materiel Command TACOM Life Cycle Management Command.

LEVEL OF REPAIR ANALYSIS (LORA)
1. COMPASS. COMPASS is the Army approved system-level LORA model. This program is available to all U.S. Government offices and their contractors working under a current contract. The Contractor may obtain the COMPASS software at: https://www.logsa.army.mil/#/lec/compass
Software training on is available to the contractor. The Contractor may schedule training by contacting:
The Technical Support Branch: usarmy.redstone.LDAC.mbx.tsb-smartdesk@mail.mil

LEVEL OF REPAIR ANALYSIS (LORA)
a. The first step in the process is to develop a LORA candidate list; initial candidate list shall include all repairable items/components. A copy of this list shall be provided to the government.
b. The initial candidate list shall include all repairable items/components. If the repairable items/components are determined not to be viable LORA candidates when analyzed, these items/components shall be annotated as not applicable (N/A).
c. Levels of Maintenance – For the purpose of this effort the following levels shall be used: Field
Maintenance (DS), Sustainment Maintenance (DEPOT and Contractor).
d. Remove/Replace and Repair Time - The current commercial repair/replace times shall be used. If times are not available, times shall be estimated using MIL-HDBK-470A.
e. Failure Rates – The current commercial failure rates shall be used for the initial/baseline results.
The failure rates shall be increased as stated elsewhere in this attachment.
f. Unknown DATA - Elements that do not have current or known data shall use historical data for that item/component or a like item/component; data shall be either commercial or military.
g. Special Tools – All individual Special Tools needed for repair tasks shall be added under Support Equipment. Support Equipment shall be incorporated in each evaluation.
h. All data shall be entered in COMPASS and be as complete as possible, this is to ensure that the evaluations are as accurate as possible.
3. Evaluations to be completed for this effort
a. Non-Economic Evaluation
b. Economic Evaluation
c. Sensitivity and Trend Analysis – The Parameters that are to be adjusted for these analyses are:
Mean Time Between Failure (MTBF) - shall be +/- 30 percent
Operating Hours – Shall be +/- 50 percent
Mean Time To Repair (MTTR) – shall be +/- 30 percent
For all Evaluations listed above the contractor shall provide a Front End Analysis (FEA) and Maintenance Policy for each evaluation completed.
