Description / Abstract:

This SAE Aerospace Recommended Practice (ARP) 4294 is directed at life cycle cost (LCC) analysis of aerospace propulsion systems and supplements AIR1939.

Specific topics addressed by ARP4294 are listed below:

a. Propulsion system LCC element structure.

b. Information exchange and relationships with:

(1) Aircraft manufacturer

(2) Equipment suppliers

(3) Customer

c. The relationship of the LCC element structure to work breakdown structures.

d. The relationship between LCC analysis and other related disciplines (e.g., technical (performance analysis, weight control, component lives), reliability, availability and maintainability (RAM), integrated logistic support (ILS), production and finance)

e. Classification of the accuracy and applicability of LCC assessments.

Purpose: ARP4294 supplements the general guidelines of AIR1939 and complements ARP4293 by providing specific data formats and data transfer procedures to increase the effectiveness of LCC evaluations. ARP4294 promotes the consistency and understanding of information exchanged at the interfaces between customers, aircraft manufacturers, engine producers, and equipment suppliers. It clarifies the relationships between LCC and related disciplines. In support of the free flow of LCC information between customers, manufacturers, and equipment suppliers, ARP4294 provides classifications governing the applicability of LCC analyses.
