Specification for Aero and Aero-Derived Gas Turbine Engine Lubricants

2018-03-04
CURRENT
AS5780D
This specification defines basic physical, chemical, and performance limits for 5 cSt grades of gas turbine engine lubricating oils used in aero and aero-derived marine and industrial applications, along with standard test methods and requirements for laboratories performing them. It also defines the quality control requirements to assure batch conformance and materials traceability, and the procedures to manage and communicate changes in oil formulation and brand. This specification invokes the Performance Review Institute (PRI) product qualification process. Requests for submittal information may be made to the PRI at the address in Appendix D Section D.2, referencing this specification. Products qualified to this specification are listed on a Qualified Products List (QPL) managed by the PRI. Additional tests and evaluations may be required by individual equipment builders before an oil is approved for use in their equipment.

Technical Guidelines for Aerospace and High Performance Electronic Systems Containing Lead-free Solder and Finishes

2018-03-01
WIP
GEIAHB0005_2A
This document is intended for use as technical guidance by Aerospace system suppliers, e.g., Aerospace system Original Equipment Manufacturers (OEMs) and Aerospace system maintenance facilities, in developing and implementing designs and processes to assure the continued performance, quality, reliability, safety, airworthiness, configuration control, affordability, maintainability, and supportability of high performance aerospace systems (subsequently referred to as AHP) both during and after the transition to Pb-Free electronics. This document is intended for application to aerospace products; however, it may also be applied, at the discretion of the user, to other products with similar characteristics, e.g., low-volume, rugged use environments, high reliability, long lifetime, and reparability. If other industries wish to use this document, they may substitute the name of their industry for the word "Aerospace" in this document.

Landing Gear Safety Criticap Processes

2018-02-28
WIP
AIR6813
There are a number of safety critical processes that are common to landing gear systems. A safety critical process (CSP) is a landing gearmaintenance manufacturing, repair or overhaul process which if ommitted or preformed incorrectly will cause failure of a safety citical item (CSI) in operation. A CSI is a landing gear item whose failure or omission will cause more than $1M in damage, serious injury or death. This AIR will define methods and modes of failure for CSPs based on experience.

Information on Hard Landings

2018-02-27
WIP
AIR5938A

This document provides information on the current practices used by commercial and military operators in regards to hard landings (or overload events designated as hard landings). Since detailed information on inspections would be aircraft specific, this AIR provides only a general framework. Detailed information and procedures are available in the maintenance manuals for specific aircraft.

Because hard landings potentially affect the entire aircraft, guidelines are listed here for non-landing gear areas. But, the primary focus of the document is the landing gear and related systems. The document may be considered to be applicable to all types of aircraft.

This document does NOT provide recommended practices for hard landing inspections, nor does it provide recommendations on the disposition of damaged equipment. Refer to ARP 4915 and ARP 5600.

WIP
ARP7976
This Aerospace Recommended Practice provides the considerations appropriate for Engine Lubrication System Oil Tank sizing, and provides means to confirm the oil volume held within the Oil Tank is adequate for satisfactory Lubrication System performance. Two scenarios should be considered when demonstrating that the Oil Tank capacity and oil volume held within the Oil Tank are adequate, sea level engine testing and in-flight operation, when demonstrating the capability of Lubrication System to operate in support of FAA Part 23 and Part 25, CFR Part 33, and corresponding EASA CS-E regulations, and equivalent Military application requirements.

Recommended Practice for Reliability Physics Analysis of Electronic Equipment, Modules and Components

2018-02-26
WIP
J3168
This Recommended Practice describes a standard process for Reliability Physics Analysis (RPA1) for Electrical, Electronic, and Electromechanical (EEE) equipment, modules, and components used in the Automotive, Aerospace, Defense and other High-Performance (AADHP) industries The AADHP industries are characterized by long lifetimes, rugged operating environments, and stringent safety and reliability requirements. It is critical to address these requirements by 1. Assembling the best available information, technical capability, and other resources; 2. Developing consensus among the industry stakeholders on the best way to address the issues; 3. Incorporating the results in consensus industry standards that are available to all. This proposed document is a result of that approach.
