This recommended practice establishes the requirements for lubricating oil filters for general aviation reciprocating engine applications with lubricating oil systems normally operating in a pressure range of 50 - 100 psig.
This SAE Aerospace Information Report (AIR) discusses the sources of Copper in aviation jet fuels, the impact of Copper on thermal stability of jet fuels and the resultant impact on turbine engine performance, and potential methods for measurement and reduction of the catalytic activity of Copper contamination in jet fuels. This document is an information report and does not provide recommendations or stipulate limits for Copper concentrations in jet fuels.
This document establishes standard gland dimensions for low pressure static radial O-ring seal applications and provides recommendations for modifying these glands in special applications. No provisions are made in this document for anti-extrusion devices.
This SAE Aerospace Recommended Practice (ARP) addresses the characteristics required for the definition, development, and acquisition of a satisfactory airframe mounted accessory gearbox (AMAG).

This document establishes requirements, test procedures, and acceptance criteria for the fire testing of fluid handling components and materials used in aircraft fluid systems. It is applicable to fluid handling components other than those prescribed by AS1055 (e.g., hoses, tube assemblies, coils, and fittings). It also is applicable to materials, wiring, and components such as reservoirs, valves, gearboxes, pumps, filter assemblies, accumulators, fluid-cooled electrical/electronic components, in-flight fluid system instrumentation, hydromechanical controls, actuators, heat exchangers, and manifolds. These components may be used in fuel, lubrication, hydraulic, or pneumatic systems.
This specification covers the general design, testing, and safety requirements for aircraft tank mounted fuel booster pumps used for engine fuel feed, transfer, and jettison.
This metric SAE Aerospace Information Report (AIR) details a ball-on-cylinder (BOC) test device and specifies a method of rating the relative lubricity of aviation turbine fuel samples. The BOC produces a wear scar on a stationary steel ball by forcing it with a fixed load against a fuel wetted steel test ring in a controlled atmosphere. The test ring is rotated at a fixed speed so its surface is wetted by a momentary exposure to the fluid under test. The size of the wear scar is a measure of the test fluid lubricity and provides a basis for predicting friction or wear problems.

This ARP is intended as a guide toward a standard practice, but may be subject to frequent change reflecting experience and technical advances. Use of this AIR is not recommended where flexibility of revision is impractical. Anyone interested in current information on BOC developments and technology should contact the Coordinating Research Council (CRC) Aviation Group on Aviation Fuel Lubricity.
This procedure is intended to apply to all engine or airframe mounted fuel pumps and controls when required by the applicable specification. The procedure recommends a recirculation system similar to ARP492 to control the fuel properties affecting the fluid and its ability to "release" fuel vapors and dissolved air and have these "re-entrained or dissolved" during the fluid recovery process back to the tank and the original starting conditions.
