ARP4754B Clarification Notice to address typographical errors and clarify portions of the document to facilitate usage of the newly released ARP4754B.

The document describes typical processes with examples on how to manage reliability assessment hardware and software used on structural health monitoring systems, and for structure health management solutions. It addresses reliability assessment guidelines from design phase, manufacturing, assemblies, installation, considering installation and environmental conditions. Link between Quality system and reliability assessment is developed

This document will provide topics and possible content for industry to use in setting up training programs for personnel involved in deployment of SHM systems. The two primary parts of the training are: installation and usage.

Update of when to implement a specific strain rate into tensile testing.

This specification covers a precipitation hardenable, corrosion- and heat-resistant nickel alloy in the form of seamless tubing 0.125 inch (3.18 mm) and over in nominal OD and 0.015 inch (0.38 mm) and over in nominal wall thickness.

This specification covers aircraft-quality, low-alloy steel in the form of round, seamless tubing.

This document covers the recommended practice for determining the acceptability of the dendrite arm spacing (DAS) of D357-T6 aluminum alloy castings required to have tensile strength not lower than 50 ksi (345 MPa).

This document defines a recommended practice for addressing metal additive manufacturing (AM) machine requalification for all fusion-based metal AM machines. In general, this applies to powder bed fusion (PBF) and wire- or powder-fed directed energy deposition (DED) technologies. Plasma, electron beam, or lasers are applicable energy source(s).

This SAE Aerospace Recommended Practice (ARP) defines the performance criteria and validation for tire circumferential movement on the rim, in the laboratory, by a static test, as well as a performance assessment in service. This document is applicable to braked wheel positions using both bias ply and radial aircraft tires.

This document covers all metal, self-locking wrenching nuts, plate nuts, shank nuts, and gang channel nuts made from a corrosion and heat resistant steel of the type identified under the Unified Numbering System as UNS S66286 and of 160 ksi tensile strength at room temperature, with maximum test temperature of parts at 1200 °F.

This procurement specification covers aircraft quality self-locking nuts for wrenching (hex, spline) and anchor (plate, gang channel, shank) types of nuts made from a corrosion and heat-resistant nickel-base alloy of the type identified under the Unified Numbering System as UNS N07001. Tension height nuts having overall length of threaded portion not less than 1.2 times the nominal thread diameter have 1210 MPa minimum tensile strength at room temperature. Shear height nuts having shorter threaded portion have 1100 MPa minimum tensile strength at room temperature. Maximum test temperature of parts is 730 °C.

This specification covers a magnesium alloy in the form of sheet and plate from 0.016 to 3.000 inches (0.41 to 76.20 mm), inclusive, in thickness (see 8.5).

This specification covers a magnesium alloy in the form of extruded bars, rods, wire, tubing, and profiles up to 40 square inches (258 cm2) in cross-sectional area (solids) and up to 8.5 inches (216 mm) OD by 1.188 inches (30.18 mm) wall thickness (tubing) (see 8.5).

This AS provides the minimum performance requirements for the following types of inflatable emergency evacuation devices (hereinafter referred to as device[s]): 1 Type I - Inflatable Slide: A device suitable for assisting occupants in descending from a floor-level airplane exit or from an airplane wing to the ground. A Type I off-wing slide is a device that does not include a ramp. 2 Type II - Inflatable Slide/Raft: A device suitable for assisting occupants in descending from a floor-level airplane exit or an airplane wing to the ground that is also designed to be used as a life raft. A Type II off-wing slide/raft is a device that does not include a ramp. 3 Type III - Inflatable Exit Ramp: A device suitable for assisting occupants in descending from certain overwing exits to an airplane wing. 4 Type IV - Inflatable Ramp/Slide: A device suitable for assisting occupants from an overwing exit or airplane wing to the ground.

This specification covers a corrosion-resistant steel in the form of bars, wire, forgings, and forging stock.

This specification covers unalloyed copper in the form of sheet, strip, and plate at least 0.015 inch (0.38 mm) in nominal thickness.
