The SAE Guide to APU health management establishes the foundation for developing a successful APU health management program at any aircraft or APU operator, such as an airline, an OEM, an equipment supplier, or a military transport unit. This guide identifies the best practices for using an APU health management program to improve dispatch reliability and to satisfy Extended Operations (ETOPS) availability requirements.
Rationale: This guide was developed to assist Auxiliary Power Unit (APU) operators in identifying the key steps in establishing and
maintaining a successful APU health management program that meets both the economic and the technical requirements
of their business. This guide was developed for all APU operators or life-cycle owners, such as commercial operators,
Original Equipment Manufacturers (OEM), equipment suppliers, and military transport units.
