CURRENT
AS6173A
This standard covers design requirements, performance requirements, and methods of procurement for tools and associated accessories used to cut aerospace vehicle electrical wire and cable. Aerospace vehicle electrical wire has stranded conductors with protective plating and specialized insulation. Poor quality wire cutting can compromise the performance of wiring.

Evaluation of Gas Turbine Engine Lubricant Compatibility with Elastomer Slabs - Long Duration Test

2018-12-10
CURRENT
ARP6917
This test method provides procedures for exposing specimens of elastomer material (slab form) representative to those used in gas turbine engines to aviation lubricants under extended duration and engine relevant thermal conditions. For AS5780 requirements the time is at least 1800 hours and temperatures are 100 °C to 160 °C. Positive volume change is an indication of specimen swell and subsequent negative volume change is an indication of specimen deterioration, both properties are important in the evaluation of the compatibility of the lubricant with elastomers used in the construction of the gas turbine.

A Process for Utilizing Aerospace Propulsion Health Management Systems for Maintenance Credit

2018-12-06
CURRENT
ARP5987
The process detailed within this document is generic and can be applied to commercial and military applications. It applies to the entire end-to-end health management system throughout its lifecycle, covering on-board and on-ground elements. The practical application of this standardized process is detailed in the form of a checklist. The on-board element described here are the source of the data acquisition used for off-board analysis. The on-board aspects relating to safety of flight, pilot notification, etc., are addressed by the other SAE Committees standards and documents. This document does not prescribe hardware or software assurance levels, nor does it answer the question “how much mitigation and evidence are enough”. The criticality level and mitigation method will be determined between the ‘Applicant’ and the regulator.

Electronic Engine Control Specifications and Standards

2018-12-05
CURRENT
AIR4250C
This report lists documents that aid and govern the design, development, certification, and utilization of aerospace electronic engine control systems. The report lists the military and industry specifications and standards that are commonly used in electronic engine control system design. Also included are Airworthiness Authority documents and requirements associated with certification. However, these lists are not necessarily complete. The specifications and standards section has been divided into two parts: a master list, and a categorized list that provides a functional breakdown and cross reference of these documents. For specifications and standards, the issue available during the latest revision to this document is listed. Details of current revisions for many documents are available in the Department of Defense Index of Specifications and Standards (DODISS). It should be noted that not all of these documents are referenced or even recognized by all certification authorities.
