Description / Abstract:
This SAE Aerospace Information Report (AIR) covers the
generation of used phosphate ester aviation hydraulic fluid
(AS1241) that is deemed waste because it does not meet in-service
limits for use in aircraft. This document also lists the relevant
United States Environmental Protection Agency (U.S. EPA)
regulations on used hydraulic fluid that are in force at the time
of this report's publication. Regulations of other countries as
well as those for states and municipalities should be consulted
prior to initiating any of the waste disposal recommendations
listed here.
Purpose
The purpose of this document is to instruct the users of AS1241
hydraulic fluid on appropriate actions for minimizing the
generation of waste hydraulic fluid, thereby allowing for longer
service life of the fluid and reducing operating costs associated
with the handling and disposal of waste fluid.
