AIR 1939 addresses communication of LCC data between equipment suppliers, aircraft engine producers, aircraft manufacturers, and users, as illustrated in Figure 1. The LCC data categories addressed include: research, development, test and evaluation (RDT&E); acquisition (initial procurement and investment); and operating and support (O&S) costs. While input and output formats are suggested, calculation procedures and cost methodology are specifically excluded since many LCC models preferred by the industry are company sensitive or proprietary (Figure 1). The relationship of LCC input data to program phase is described. Ground rules and assumptions are addressed. A glossary of LCC terms is provided. The LCC impact of propulsion systems on other aircraft systems is considered. This document was specifically developed for military propulsion system cost analysis.

SAE TA-HB-0007-1A is an integral part of the following suite of documents, which are meant to be used together: SAE TA-STD-0017A, Product Support Analysis, SAE GEIA-STD-0007C, Logistics Product Data, SAE GEIA-HB-0007B, Logistics Product Data Handbook, and SAE TA-HB-0007-1A. MIL-HDBK-502A, Product Support Analysis provides additional guidance and instruction applicable to United States DoD programs. SAE TA-STD-0017A Product Support Analysis is a standard which prescribes a set of analysis activities for designing support and supporting the design of a product. MIL-HDBK-502A provides DoD users with implementation guidance for SAE TA-STD-0017A. The results of the analysis are Logistics Product Data. SAE GEIA-HB-0007B is a companion handbook to SAE GEIA-STD-0007C.
