Carbon Brake Contamination and Oxidation

2016-04-12
CURRENT
AIR5490A
This document provides information on contamination and its effects on brakes having carbon-carbon composite friction materials (carbon). Carbon is hygroscopic and porous, and therefore readily absorbs liquids and contaminants. Some of the contaminants can impact intended performance of the brake. This document is intended to raise awareness of the effects of carbon brake contamination and provide information on industry practices for its prevention. Although not addressed in this report, contaminants can cause problems with other landing system components including tires.

Disposition of Damaged Wheels Involved in Accidents/Incidents

2005-05-20
CURRENT
ARP5600
This SAE Aerospace Recommended Practice (ARP) establishes a procedure for disposition of aircraft wheels that have been involved in accidents/incidents or have been exposed to overheat conditions or overload conditions from loss of adjacent tire pressure (paired wheels) or wheel tie bolts.

WIP
ARP6812
This SAE Aerospace Recommended Practice (ARP) covers the functional, design, construction, and test requirements for Brake Temperature Monitoring Systems (BTMS), and sometimes referred to as Brake Temperature Indication Systems (BTIS). The BTMS is limited to aircraft where a dispatch indication and brake temperature indication is required. The scope of this BTMS equipment shall be limited to the 1) brake temperature sensor or indicator, 2) temperature reference measurement, if required, and 3) processing and communication of brake temperature. This recommended practice will not address cockpit ergonomics and aircraft operating procedures.

Test Method for Catalytic Carbon Brake Disk Oxidation

2013-12-04
WIP
AS6289
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.

Minimum Performance Requirements for Transport Airplane Wheel and Brake Assemblies Using Electric Power Actuation

2012-07-11
CURRENT
AS5663A
In lieu of TSO-C135, this SAE Aerospace Standard (AS) prescribes the minimum performance standards for wheels, brakes, and wheel and brake assemblies using electric power actuation for transport category (14 CFR Part 25) airplanes. Testing is limited to that necessary to establish minimum performance related to strength, robustness, stopping capability, and energy absorption to ensure measurable, repeatable industry accepted standards for these aspects of wheel and brake performance. The test parameters associated with electric braking actuation are defined around the state of the technology at this time, typically comprised of an Electro-Mechanical Actuator (EMA) controlled by a control system delivering electric power and effecting motor control.

Test Method for Catalytic Carbon Brake Disk Oxidation

AIR5567B
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.

HISTORICAL
ARP5381
This Minimum Performance Document defines the testing required for wheels, brakes, and wheel and brake assemblies to be used on civil aircraft certified under 14 Code of Federal Regulations (CFR) Part 23, 27, and 29. Compliance with this document is recommended to assure that the equipment supplied will meet the intended design function when installed on aircraft. Compliance with this document does not constitute authorization for installation on an aircraft. The combined recommendations of this document provide an acceptable practice, but not the only practice, for obtaining authorization to apply TSO markings on the equipment.
