Forgings, Steel, For Aircraft/Aerospace Equipment

2019-10-21
WIP
AMS6400A

This specification establishes requirements for steel forgings of any shape or form from which finished parts are to be made (See 8.2, 8.3, & 8.4). This specification covers steel forgings suitable for use in the construction of aircraft/aerospace equipment

Metallic Whiskers

2019-10-17
CURRENT
AIR4129A
This AIR presents an abbreviated review of the metallurgical phenomena known as whiskers. It is not all encompassing; rather, it is intended to introduce the design engineer to the technical issues of metallic whiskers, their formation, and the potentially dangerous problems they can cause.

Aluminum Alloy, Extrusions 1.0Mg - 0.60Si - 0.30Cu - 0.20Cr (6061-T6511) Solution Heat Treated, Stress Relieved by Stretching, Straightened, and Precipitation Heat Treated

2019-10-17
CURRENT
AMS4173G
This specification covers an aluminum alloy in the form of extruded bars, rods, wire, profiles, and tubing. These extrusions have been used typically for parts requiring moderate strength and where distortion during machining must be minimized, but usage is not limited to such applications.
Standard

Minimum General Standards for Oxygen Systems

2019-10-16
WIP
AS861C
This standard covers all types of oxygen breathing equipment used in non-military aircraft. It is intended that this standard supplement the requirements of the detail specification or drawings of specific components or assemblies, e.g., regulators, masks, cylinders, etc. Where a conflict exists between this and detail specifications, detail specifications shall take precedence.

Nickel Alloy, Corrosion and Heat-Resistant, Bars, Forgings, and Rings, 72Ni - 15.5Cr - 0.95Cb - 2.5Ti - 0.70Al - 7.0Fe, Consumable Electrode or Vacuum Induction Melted, 1800 °F (982 °C) Solution Heat Treated, Precipitation Hardenable

2019-10-16
CURRENT
AMS5671H
This specification covers a corrosion and heat-resistant nickel alloy in the form of bars up to 4.00 inches (101.6 mm) exclusive in nominal diameter or thickness, forgings 4.00 inches (101.6 mm) exclusive in nominal thickness, flash welded rings up to 4.00 inches (101.6 mm) exclusive in nominal radial thickness, and stock of any size for forging or flash welded rings (see 8.6).

Aerospace-Solenoid Valve, Hydraulic, Three Way, Two Position, Direct Acting

2019-10-10
WIP
ARP4945B
This SAE Aerospace Recommended Practice (ARP) is intended as a guide to aid in the specifying and testing of direct acting three way, two position, single and multiple coil, normally open and normally closed solenoid valves used for the pilot actuation of hydraulic control systems and the control of hydraulic components. The information presented should be useful in standardizing terminology, in specifying requirements and performance parameters, and in defining test methods. The recommendations do not restrict or attempt to define the internal design features of solenoid valves. Standard mechanical, electrical and fluid porting interfaces are recommended to provide commonalty, interchangeability, design flexibility and to be more affordable. In general, this recommended practice is directed toward solenoid valves for use in military and commercial flight control and hydraulic actuation systems.

Service Damage Limits for Aircraft Hydraulic Tubing

2019-10-09
WIP
AIR1388C
This SAE Aerospace Information Report (AIR) is intended to assist in evaluating the serviceability of damaged hydraulic tubing lines. The performance requirements are outlined to which the defect sample were tested. Test methods and data are described and summarized. Permissible defect limits are listed for 6061-T6 aluminum return lines, 3000 psi hydraulic tubing of 21Cr-6Ni-9Mn SS, 304 1/8 hard, corrosion resistant steel (CRES), as well as 3Al-2.5V CWRS and 3Al-2.5V annealed, seamless titanium tubing. All dimensions are in inches unless otherwise noted.

Protective Coatings for Fasteners

2019-10-07
CURRENT
J1648_201910
This SAE Information Report is provided as an advisory guide. Careful discretion as to application is recommended. The content has been presented as accurately as possible, but responsiblity for its application lies with the user. It covers finishes applied to fasteners and related topics, corrosion resistance, lubricity, electrical grounding, ultraviolet light, and embrittlement. Table 1 lists these coatings and their properties so that finish selection can be reasonably made in accordance with known and anticipated fastener assembly applications. Application of protective coatings will affect fastener dimensions. This is especially critical for the thread fit of mating parts because the pitch diameter increases by four times the coating thickness. Explanation is covered in Section 5.
