This SAE Aerospace Information Report (AIR) discusses past and present approaches for monitoring the landing gear structure and shock absorber, 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. This AIR covers the landing gear structure and shock absorber. It does not include the landing gear systems or landing gear wheels, tires and brakes. Landing gear tire condition and pressure monitoring are detailed in AIR4830 and ARP6137, respectively.
Rationale: This SAE Aerospace Information Report (AIR) has been written to provide a review of the state-of-the-art of landing gear structural health monitoring. The document is intended to augment the work of the SAE G-11SHM by extending the airframe structural health monitoring concept to the particulars of the landing gear. The purpose of this AIR is to objectively discuss and summarize historic as well as current state-of-the-art landing gear structural health monitoring technologies.
