Effects of Extremely Cold Temperature on Landing Gear Operation
2022-03-29
CURRENT
AIR6411
This SAE Aerospace Information Report (AIR) provides information on landing gear operation in cold temperature environments. It covers all operational aspects during ground handling, takeoff, and landing. It includes effects on tires, brakes, shock struts, seals, and actuators.

Environmentally Compliant Processes for Landing Gear
2022-09-08
CURRENT
AIR5479B
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.

AIR5479A
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.

GLAND DESIGN: SCRAPER, LANDING GEAR, INSTALLATION
1994-04-01
HISTORICAL
AS4052
This SAE Aerospace Standard (AS) covers an alternate gland design for the installation of scraper/wiper rings in the lower end of landing gear shock struts for the purpose of contaminant exclusion. The defined scraper gland covered by this document, as shown in Table 1, is a variant of MIL-G-5514, the accepted gland standard for MS28775. Piston diameters, gland internal diameters, and the groove sidewall angles and surface finish are defined by MIL-G-5514, but the gland outer retaining wall diameter is changed. AS4088 is similar to this document, but was developed by SAE A-6 for flight control and general purpose cylinders. It differs from this document primarily by the clearance between the rod (piston) and outer gland wall. Since landing gears are more susceptible to dirt contamination, the additional clearance provides a larger path to allow excessive dirt accumulation to exit the gland.

Inflator Assembly and Gage Elements, Pneumatic Pressure, Remote Control, Direct Reading
2018-04-09
CURRENT
AS85352A
This specification covers a direct reading, remote control, pneumatic pressure inflator assembly, for use on aircraft tires and struts having pneumatic pressure requirements up to 600 psi. It includes pressure relief provisions to provide for safe inflation. Also included are dual chuck stem gages for measuring tire pressure.

Landing Area/Landing Gear Compatibility - A Brief History of SAE/Corps of Engineers Cooperation
2014-12-01
CURRENT
AIR4243A
This document discusses the work done by the U.S. Army Corps of Engineers and the Waterways Experiment Station (WES) in support of SAE A-5 Committee activity on Aerospace Landing Gear Systems. It is an example of how seemingly unrelated disciplines can be combined effectively for the eventual benefit of the overall aircraft system, where that system includes the total airfield environment in which the aircraft must operate. In summary, this AIR documents the history of aircraft flotation analysis as it involves WES and the SAE.

Landing Gear (Engine Off) Taxi System
2021-02-03
CURRENT
AIR6246
This SAE Aerospace Information Report (AIR) will review new landing gear (engine off) taxi system technologies currently being developed by various companies and describe the basic design concepts and potential benefits and issues. This AIR will identify the associated systems that could be affected by this new technology. The document will review basic design and operational requirements, failure modes and identify system certification requirements that may need to be addressed. The technology is evolving as this paper is being written and the data present is currently up to date as of 2015.
