Full title and description

SAE ARP1493C — Wheel and Hydraulically Actuated Brake Design and Test Requirements for Military Aircraft. This recommended practice defines design, performance and test requirements for military aircraft wheels and hydraulically actuated brake equipment, addressing equipment characteristics, test methods and qualification criteria used in procurement and design validation.

Abstract

ARP1493C (stabilized November 1, 2013) provides recommended practices for the design and testing of wheels and hydraulically actuated braking systems used on military aircraft. The document covers equipment-level requirements, performance and environmental testing, and criteria for demonstrating structural and functional integrity of wheel and brake assemblies under operational and test conditions. It is intended to support consistent procurement, design verification, and qualification of wheel and brake hardware for military fixed‑wing aircraft.

Scope

This recommended practice covers military aircraft wheel and hydraulically actuated brake equipment. It sets out requirements and recommended test procedures for design, performance, and qualification of wheel and brake assemblies used on military fixed‑wing aircraft, including structural and functional testing under representative loads and environmental conditions. The ARP is intended for use in design, verification and procurement of wheel and brake hardware.

Key topics and requirements

• Design criteria for wheels and brake assemblies, including materials and structural considerations.
• Performance requirements for hydraulically actuated brake systems (stopping capability, fade, recovery).
• Test methods and procedures for functional, structural and endurance testing of wheels and brakes.
• Environmental conditioning and qualification tests (temperature, corrosion, contamination, shock/vibration).
• Acceptance and inspection criteria for assemblies and components.
• Interface and installation considerations between wheel/brake hardware and aircraft hydraulic systems.
• Documentation and test-reporting requirements to demonstrate compliance with the ARP.

Typical use and users

ARP1493C is typically used by aerospace design engineers, test engineers, qualification and certification teams, procurement/specification authors for military programs, component manufacturers (wheels, brake assemblies, linings, hydraulic components), and maintenance/overhaul organizations that perform acceptance testing or set maintenance inspection criteria. It is used to harmonize design expectations and test demonstrations between OEMs, subcontractors and military customers.

Related standards

ARP1493C is the 2013 revision of the ARP1493 series; previous versions include ARP1493B (2008) and ARP1493A (2007), with the original ARP1493 issued in 1979. Other related SAE and aerospace standards addressing landing gear, brake linings, tire/wheel interfaces, and hydraulic system components may be used in conjunction with ARP1493C for complete system specification and qualification.
