This ARP provides recommended practice on the considerations and methodology to demonstrate acceptable performance of the Engine components / fuel system, and APU, whilst operating throughout the flight cycle / engine duty for continuous operation with iced fuel and short duration operation with a snowshower resulting from release of accreted ice from fuel washed surfaces, where no anti-icing additives are present (e.g. Fuel System Icing Inhibitor FSII or alternative). Two scenarios must be considered when demonstrating the capability of Engine components / fuel system, and APU to operate with fuel borne ice to satisfy certification regulations applications in support of FAA Part 23 and Part 25, CFR Part 33, and corresponding EASA CS-E regulations, and equivalent Military application requirements.

This SAE Standard is intended for all sizes of fuel filters, so a variety of test stands may be required depending upon flow rate.

The importance of adequate component procurement specifications to the success of a hardware development program cannot be overemphasized. Specifications which are too stringent can be as detrimental as specifications which are too lax. Performance specifications must not only identify all of the component requirements, but they must also include sufficient quality assurance provisions so that compliance can be verified. It should be understood that in almost every case specifications for components will ultimately become part of a BINDING, WRITTEN CONTRACT (PO). The purpose of this document is to describe types of specifications, provide guidance for the preparation of fluid component specifications, and identify documents commonly referenced in fluid component specifications.
