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:

1. a Propulsion system LCC element structure.
2. b Information exchange and relationships with:
   1. (1) Aircraft manufacturer
   2. (2) Equipment suppliers
   3. (3) Customer
3. c The relationship of the LCC element structure to work breakdown structures.
4. 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).
5. e Classification of the accuracy and applicability of LCC assessments.
