Scope
This SAE Aerospace Information Report (AIR) describes the performance of platings and coatings for landing gear that potentially provide environmental compliance benefits versus the current baseline processes. The hazardous systems addressed in this version of the document include cadmium plating, chromated primers, and high VOC (volatile organic compounds) topcoats.
Available data are presented for various standard tests in order to compare the replacement candidates. Conclusions are made as to the best performer(s) for each test section presented. These conclusions are not to be regarded as recommendations for or against any of the candidates.
The AIR applies to landing gear structures and mechanisms for all types of civil and military aircraft. The potential replacements apply to both original equipment manufacturer (OEM) hardware and overhaul of in-service landing gears.
Rationale
This document has been reaffirmed to comply with the SAE 5-Year Review policy.

Issuing Committee
A-5 Aerospace Landing Gear Systems Committee
The A-5 Committee addresses all facets of aerospace landing gears: design, maintenance and in-service experience. It publishes Aerospace Information Reports (AIR), Aerospace Recommended Practices (ARP) and Aerospace Standards (AS) for use throughout the industry. These documents provide current design information, recommended design practices and design standards for landing gear systems. A-5 also provides a forum for presentations on current technology and technical interchanges needed by each engineer to stay abreast of a fast moving field.
A-5 is comprised of three subcommittees: Wheels & Brakes (A-5A), Landing Gear, Struts and Couplings (A-5B) and Tires (A-5C). A-5 is an assemblage of top landing gear engineers from throughout the industry and the world including customers and commercial users. The committees form and modify the various specifications and standards for both military and commercial applications. Benefits from committee participation are knowledge, customer responses and first-hand input into tomorrow's specifications.Reference
* 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.
