This document addresses AS8879 thread inspection issues relating to selection, usage and capability of gages. It addresses the selection of calibrated measurement gages, the need for defined quality metrics, the methodology of determining the appropriate guardband factors, and the minimum inspection requirements for single element pitch diameter gages. Users of this document shall apply the information described herein for the evaluation of the capability of their measurements based on the measurement consumer risk. It involves the analysis of the measurement (product) distribution and biases of both the product and measurement system distributions. It protects the consumer from the worst case distribution results. A whitepaper has been developed to provide supporting documentation and the rationale used in the development of this standard. This whitepaper will be published by the SAE as an Aerospace Information Report (AIR6553).
This specification establishes the procedure for installing self-locking, floating, attached retention element (A.R.E.) nut assemblies and defines the necessary hole preparation.
This SAE Aerospace Standard (AS) provides minimum design, hole preparation, installation and removal requirements for AS3272, AS3273, MA3274, and MA3275 serrated shank self-locking clinch nuts. This standard is applicable when specified on engineering drawings or in procurement documents.
This SAE Metric Aerospace Standard (MA) provides minimum design, installation, and removal requirements for MA3520 and MA3521 thin wall inserts and is applicable when specified on engineering drawings or in procurement documents.
This standard establishes the basic triangular profile for the MJB thread form, the design profiles, standard pitches, tolerance classes, formulae for tolerances and dimensions, tolerance tables, and a system of designations. Because of the specialized application for buttress threads, no preferred diameter-pitch series have been established for this standard and each application will require use of the thread formulae for dimensions and related tolerances given herein for deriving the thread dimensional requirements.
Orientation of the engine, engine axis and coordinate system referred to herein shall be the conventional terminology used in all references to aircraft gas turbine engines.

This paper was prepared to support supersession of MIL-S-8879C with Screw Thread Conformity Task Force selected industry standard AS8879C, published by the Society of Automotive Engineers (SAE). Other documentation changes will be covered by separate papers. Separate papers are anticipated for thread gaging issues, and thread gage calibration procedures. The STC-TF decided that the thread design standard needed to be completed before thread gage definition could be addressed. Thread gage definition has to be known before calibration procedures can be addressed.
This standard provides a method of applying surface roughness, waviness and lay control. The data included herein also covers the method of applying surface roughness symbols and related designations to drawings and specifications of parts when applicable. This standard is based on the Arithmetical Average (AA) method of instrumentation. Data compiled are based on current manufacturing practices. It also includes a summary of data published in the latest issue of the American Standards Association publication ASA B46.1.
This standard provides a method for the application of surface finish control primarily to aircraft engine and propeller parts. Recommendations for a Surface Roughness Standard are contained in A.S.A. publication B46 and this S.A.E. Aeronautical Standard contains a summary of information therein plus other information which has been compiled from current manufacturing practice.
