FZG Test Review
2017-02-28
WIP
AIR6919
Over the past several years the FZG A/8.3/90 test method has been used to evaluate current qualified aviation lubricants. The results of the effort have been summarized in this document as a historical reference to document the findings made from the committee.

Evaluation of Corrosiveness and Oxidation Stability of Aviation Lubricant
2020-08-28
WIP
ARP6839
This test method describes a standardized process to evaluate the an aviation lubricant’s resistance to oxidation and corrosion-based degradation and to evaluate the fluid’s tendency to corrode various metals. Fluids are evaluated under a low-moisture atmosphere at a variety of times and temperatures.

Stability of Aircraft Greases
1995-05-01
CURRENT
AIR41
The purpose of this information report is to summarize and document data regarding possible alternatives to the use of cadmium plating on hardware typical of the aerospace hose and fitting industry. To document and provide access to information obtained by an industry survey.

Cockpit Information Required for Helicopter Turbine Engine Operation and Maintenance
2022-03-29
WIP
AIR1963B
This SAE Aerospace Information Report (AIR) identifies Propulsion EngineerÕs recommendations for the instrumentation that is required for the safe operation and maintenance of turbine engines as installed in helicopters. It should be used as a guide for cockpit layout, as well as a reference for maintenance considerations throughout the propulsion area. Propulsion instruments should receive attention early in the design phase of the helicopter. Maintenance and diagnostics recorders are not considered within the scope of this document. (See ARP1587, "Aircraft Gas Turbine Engine Monitoring System Guide".)

Corrosion Preventative Characteristics of Aircraft Greases
1995-05-01
CURRENT
AIR40
The objective of this work was to develop a relatively simple screening or bench test, or a combination of such tests, which would evaluate aircraft greases in respect to corrosion protection under the operating conditions described above.
Standard

Contamination Studies of Aircraft Greases
1995-05-01
CURRENT
AIR42
Certain techniques involved in determining the dirt or abrasive content of aircraft greases are considered inadequate. It is desirable to develop a method of analysis which will definitely identify the quantity, size, and degree of abrasiveness of foreign substances in lubricating greases.
Standard

Low Temperature Torque Test for Aircraft Greases
1995-05-01
CURRENT
AIR43
The objective of this investigation was to develop a test method for measuring the resistance to rotation of a ball bearing, caused by the grease in that bearing, as a function of temperature. Low temperatures were of particular interest, and it was desired that the test results be expressed in terms which could be used in mechanism design by proper correction for bearing size, etc. It was also desired that the method be capable of measuring 'break away' as well as the running torque of a bearing filled with grease.
Standard

Load Support Characteristics of Aircraft Greases
1995-05-01
CURRENT
AIR44
The objective of this work was to develop a relatively simple bench test or performance test, or a combination of tests, which would be valid for evaluating greases in respect to load support characteristics, when the greases were used in journal bearings or in actuator-type mechanisms.
