This specification covers bolts and screws made from a corrosion and heat resistant, martensitic iron base alloy of the type identified under the Unified Numbering System as UNS S17400. The following specification designations and their properties are covered: AS7474: 140 ksi minimum ultimate tensile strength at room temperature, 100 ksi stress corrosion test, 72 ksi to 7.2 ksi tension-tension fatigue AS7474-1: 140 ksi minimum ultimate tensile strength at room temperature, 100 ksi stress corrosion test, 88 ksi minimum ultimate shear strength at room temperature
This SAE Aerospace Recommended Practice (ARP) describes recommended sampling conditions, instrumentation, and procedures for the measurement of non-volatile particle number and mass concentrations from the exhaust of aircraft gas turbine engines. Procedures are included to estimate sampling system loss performance. This ARP is not intended for in-flight testing, nor does it apply to engines operating in the afterburning mode. This ARP is intended as a guide toward standard practice and is subject to change to keep pace with experience and technical advances.
This document provides recommended best practice methods and processes for the in-service inspection, evaluation and cleaning of all physical contact (PC) fiber optic interconnect components (termini, alignment sleeves and connectors), test equipment and test leads for maintainers qualified to the approved aerospace fiber optic training courses developed in accordance with ARP5602 or ARINC807. This document also provides a decision-making disposition flowchart to determine whether the fiber optic components are acceptable for operation. For definitions of individual component parts refer to ARP5061.
This SAE Aerospace Information Report (AIR) presents historical information and background data related to hydrant valves and couplers used in worldwide ground refueling of commercial aircraft (hereafter generically referred to as hydrant devices). Military hydrant devices are not included since their mission requirements demand approaches that may differ.
This SAE Aerospace Standard (AS) covers helical coil locking screw thread inserts made from formed wire in which the inner surface of the coil, after assembly, provides threads of standard Unified 60 degrees form as specified on the assembly drawing. This document also covers the performance requirements of the locking feature of the insert which will retain United ANSI B1.1 (UN Profile) or AS8879 (UNJ Profile) external threaded parts.
To establish external dimensions for shafts requiring shallow grooves and internal dimensions for mating locking devices when used with parts dimensionally equivalent to Bearing Retaining Spanner Nuts, MS172236 thru MS172270.
This SAE Aerospace Standard (AS) covers helical coil stud locking screw thread inserts made from formed wire in which the inner surface of the coil, after assembly provides threads of standard Unified 60° form as specified on the assembly drawing. This standard also covers the performance requirements of the locking feature of the insert which will retain Unified ANSI B1.1 (UN Profile) or AS8879 (UNJ Profile) external threaded parts.
To establish the performance requirements of helical coil stud locking screw thread inserts.
