This SAE Aerospace Information Report (AIR) describes the performance of plating’s 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.
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.
This report provides information regarding environmentally compliant processes for landing gear applications. This document will require periodic review in order to stay up to date with latest environmental regulations.This revision updates Sources of Data, SAE Publications, ASTM Publications and US Government
Publications sections to reflect current references. The Replacement for Cadmium section has been updated, Primer and Topcoat section has been combined, and Replacement of Chrome Plating section has been added to reflect the latest industry replacement processes.
