The Consolidated Automated Support System (CASS) is a computerized Automatic Test Equipment (ATE) system that is currently being fielded by the Department of the Navy. Over the next several years, CASS will replace many existing ATE systems and help the Navy standardize test and training procedures. The Director of the Navy's Air Warfare Division (N88) and the Support Equipment Office (PMA-260) asked CNA to review the Navy's current plans for CASS implementation within the fleet. Among other things, these plans call for the phased integration of CASS into carrier Aircraft Intermediate Maintenance Departments (AIMDs). This paper is part of our workload assessment of these plans for carrier AIMDs. Our sponsors wanted answers to two questions: (1) how many (total) CASS stations do carrier AIMDs need?; and (2) more specifically, how many of each type of CASS do they need? In a previous analysis, we explored these questions for CASS support of existing weapons systems only. In this paper, we expand on that analysis by including CASS support of emerging weapons systems as well.

In a previous research, we showed how the Navy can cut the cost of carrier Aviation Consolidated Allowance Lists (AVCALs) by as much as 26 percent without cutting readiness by implementing Readiness-Based Sparing (RBS). The RBS method of selecting inventory allowances is different from the current Demand-Based Sparing (DBS) method in that it links supply resources to aircraft readiness at least cost. Our earlier RBS work prompted the Navy to conduct an at-sea test of an RBS AVCAL on USS AMERICA. The Navy asked us to perform the analysis and report the results. In this memorandum, we analyze how well AMERICA's new RBS AVCAL supported the airwing during its 1993-94 deployment and report our findings. We summarize the results of our analysis and the aviation support lessons we learned. We discuss how RBS AVCALs fit into the Integrated Logistics Support (ILS) system, present our analysis approach, and describe our analysis of mission capable rates, maintenance operations, and cannibalization actions.

The main objective of this study is to develop the cost-versus-readiness relationship for alternative aviation supply inventories (called AVCALs). This analysis will help the Navy develop future inventory policy by answering questions like: (1) what are the alternative supply support options and (2) what is th e expected loss in readiness when supply support costs are reduced.
