To recommend supplementary design criteria to enhance the endurance, reliability, and dependability of transport aircraft wheels and brakes.

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.

The focus of this SAE Aerospace Standard (AS) is the integration of thermally actuated pressure release devices, hereafter referred to as fuse plugs, with the wheel and brake assembly. It does not address the manufacturing, quality or acceptance test requirements pertaining to the production of these fuse plugs. It establishes minimum design, installation, qualification, and operational requirements for fuse plugs which are used only in tubeless tire type aircraft braked wheels. Fuse plugs are designed to completely release the contained inflation pressure from a tubeless tire and wheel assembly when brake generated heat causes the tire or wheel to exceed a safe temperature level. The objective is to prevent tire or wheel rupture due to brake generated heat that could cause an unsafe condition for personnel or the aircraft.

The scope of the test method is to provide stakeholders including fluid manufacturers, brake manufacturers, aircraft constructors, aircraft operators and airworthiness authorities with a relative assessment of the effect of deicing chemicals on carbon oxidation. This simple test is only designed to assess the relative effects of runway deicing chemicals by measuring mass change of contaminated and bare carbon samples tested under the same conditions. It is not possible to set a general acceptance threshold oxidation limit based on this test method because carbon brake stack oxidation is a function of heat sink design and the operating envirnoment.

This standard establishes minimum design, installation, qualification, and operational requirements for thermally actuated, pressure release devices for use only in tubeless tire type aircraft wheels. These devices are designed to completely release the contained air pressure from a tubeless tire and wheel assembly when absorbed and/or brake generated heat causes the tire or wheel to exceed a safe pressure/temperature/load operating level. The objective is to prevent tire or wheel rupture from brake generated heat which could cause serious personnel injuries or serious aircraft operational hazards.

This technical report documents three surveys to determine realistic vibration requirements for skid control systems specifications and obtain updated vibration information for locations in aircraft where skid control system components are mounted.

This technical report documents three surveys to determine realistic vibration requirements for skid control systems specifications and obtain updated vibration information for locations in aircraft where skid control system components are mounted.

This specification covers minimum requirements for skid control equipment for use on all types and models of civil aircraft. It shall be the responsibility of the applicant (See Paragraph 5.1) to determine the compatibility of these requirements with the applicable aircraft and to specify requirements in excess of these minimums as necessary.

This SAE Aerospace Recommended Practice (ARP) defines recommended planning and substantiation procedures and associated reviewing and approval processes to confirm that proposed changes do not compromise the demonstrated safety of the originally certified aircraft, and performance and aircraft compatibility are appropriately addressed in aircraft documentation. Successful demonstration also requires that failure modes be identified and mitigation provided for each. These procedures apply to modifications made by the original component or assembly supplier as well as approval of an alternate supplier.

This SAE Aerospace Recommended Practice (ARP) specifies the minimum design and test recommendations for aircraft tubeless tire and wheel overpressurization release devices to protect from possible explosive failure of the contained air chamber due to overinflation. This device will not protect against flash fire explosive conditions within the air chamber which may occur due to extremely overheated brakes. To protect against this condition, nitrogen or other inert gas should be used for inflation.

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.
