This SAE Aerospace Information Report (AIR) discusses past and present approaches for monitoring the landing gear structure and shock absorber (servicing), opportunities for corrosion detection, methods for transient overload detection, techniques for measuring the forces seen by the landing gear structure, and methods for determining the fatigue state of the landing gear structure. Landing gear tire condition and tire pressure monitoring are detailed in ARP6225, AIR4830, and ARP6137, respectively. Aircraft Brake Temperature Monitoring Systems (BTMS) are detailed in AS1145.
Rationale
This report provides engineering reference data, historical information, and educational material useful to the technical community regarding Structural Health Monitoring (SHM) systems for landing gear. The report is being updated to ensure the latest information on SHM technology is available to the technical community. This document will require periodic review in order to stay up to date with latest developments in SHM technologies.
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.
* 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.

Search Tips: Search Operators:AND, OR, NOT; Wild Cards; Using Quotes
SAE MOBILUS® Search Tips
Please note: All terms not contained within quotes, will be evaluated using the OR operator. This means that your search results will contain all results that contain ANY of the entered terms.
AND, OR, NOT
SAE MOBILUS supports the use of the AND, OR and NOT BOOLEAN operators ONLY function with the Advanced Search.
Wild Cards
Using the asterisk, ( * ) allows you to search for a partial word. For example, entering a keyword search of aero* will search for any word beginning with aero.
Using the question mark, ( ? ) allows you to search for a word with a single character wildcard. For example, searching for t?re would match both tire and tyre
Using Quotes
Words in double quotes " " are treated as a phrase. Conducting a search for "heat model" will return all results in which the exact phrase "heat model" is found, while "heat modeling" would NOT be included.
A term combined with a phrase will be joined with an OR operator.
Searching for Standards
When searching for a standard please use the entire Document Number assigned, which includes the abbreviation. A space can be used, or omitted between the abbreviation and number.
