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 inflation pressure from a tubeless tire and wheel assembly when brake generated heat causes the assembly to exceed a safe temperature operating level. The objective is to prevent tire or wheel rupture due to brake generated heat which could cause serious personnel injuries or serious aircraft operational hazards.

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 test is 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.

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 standard 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 to determine the compatibility of these requirements with the application aircraft and to specify requirements in excess of these minimums as necessary.

This SAE Aerospace Information Report (AIR) describes available technology and current aerospace industry practices used for the selection, testing, lubrication, and sealing of single row tapered roller bearings to reduce bearing damage as a problem in the aircraft industry.

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) 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.

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 document was requested by the FAA to provide a technical update of TSO-C26d to address Electric Brake Actuation, standardize with TSO-C135a and address any remaining concerns with the current technical requirements in AIR5381.
