This SAE Aerospace Information Report (AIR) has been prepared to assist those who are concerned with the removal, inspection, and disposition of magnesium and aluminum wheels which may have been subjected to excessive temperatures.

This SAE Aerospace Standard (AS) defines the configuration of aircraft wheel inflation valve assemblies, including required tolerances, materials, and appropriate finishes.

This SAE Aerospace Information Report (AIR) documents general technical data associated with many of the wheels used in the Air Force.

This SAE Aerospace Standard (AS) sets forth the minimum quality required for aircraft wheel and brake castings. Its use will establish minimum acceptable requirements for internal structure and surface conditions and is predicated on the use of a casting factor for the ultimate load of more than 1.51 through 2.00. When casting factors of 1.25 through 1.50 are used, visual, penetrant, and radiographic or other approved equivalent nondestructive inspection methods shall all be required on each production casting. Where specific parts, or areas of parts, require a quality level exceeding that described by this document, the requirements shall be established by negotiation between the purchaser and vendor.

This standard sets forth the minimum quality required for aircraft wheel and brake castings. Its use will establish minimum acceptable requirements for internal structure and surface conditions and is predicated on the use of a casting factor for the ultimate load of 1.51 (minimum) to 2.00 (maximum). When casting factors of 1.25 minimum to 1.50 maximum are used, visual, penetrant, and radiographic or other approved equivalent non-destructive inspection methods shall all be required on each production casting. Where specific parts or areas require a quality level exceeding that described by this standard, the requirements shall be established by negotiation between the purchaser and vendor.

This SAE Aerospace Recommended Practice (ARP) specifies the minimum design and qualification test recommendations for aircraft wheel overpressurization release devices used with tubeless aircraft tires to protect from possible explosive failure of the contained inflation chamber due to overinflation. Devices of this type provide a means, but not the only means, for showing compliance to Subsection 25.731(d) of Part 25 of Title 14 of the Code of Federal Regulations. Devices of this type will not protect against flash fire explosive conditions within the inflation chamber which may occur due to extremely overheated brakes or spontaneous combustion caused by a foreign substance within the inflation chamber. To help protect against this condition, nitrogen (N2) or other inert gas should be used for inflation.

This SAE Aerospace Recommended Practice (ARP) defines recommended substantiation procedures and associated reviewing and approval processes to confirm that proposed changes do not compromise the demonstrated safety, performance, and airplane compatibility of the originally certified commercial and military aircraft. Successful demonstration also includes confirmation that no adverse failure modes are introduced. These procedures apply to modifications made by the original component or assembly supplier as well as certification of an alternate supplier.
