Scope
This SAE Aerospace Information Report (AIR) establishes guidance for the specification of formulated lubricant properties which contribute to the lubricating function in bearings, gears, clutches, and seals of aviation propulsion and drive systems.
Rationale
Since issuance of AIR5433B, it was discovered that the thermal conductivity for the oils listed in Table 8 were in error. After review in the E-34C Lubricating Characteristics Subcommittee, these issues have been resolved in this revision.

* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
