ARP4912C
This SAE Aerospace Recommended Practice (ARP) provides recommendations on cavity design, the installation of elastomer type spare seals in these cavities, and information surrounding elastomer material properties after contact with typical shock absorber hydraulic fluid(s) or grease. This ARP is primarily concerned with the use of spare seals on shock absorbers where only a single dynamic seal is fitted and in contact with the slider/shock absorber piston at any one time. These shock absorbers typically have a spare (dynamic) seal gland located on the outer diameter of the lower seal carrier. This spare seal gland is intended to house a spare elastomer contact seal. Split Polytetrafluoroethylene (PTFE) backup rings can also be installed in the spare seal cavity. During operation, if the fitted dynamic shock absorber standard seal begins to fail/leak, then the aircraft can be jacked up, allowing the lower gland nut of the shock absorber to be dropped down.

AIR6168A
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.

ARP5283B
The purpose of this specification is to provide airplane operators and tow vehicle manufacturers with: a. General design and operating requirements pertinent to test and evaluation of towbarless tow vehicles. Specific design requirements are provided in ARP4852 and ARP4853. b. Test and evaluation requirements. The results of these test evaluations will determine if the loads induced by the tow vehicle will exceed the design loads of the nose gear, or are within the aircraft manufacturer’s limits so that they do not affect the certified safe limit of the nose gear. The results of these test evaluations will also determine if a stability problem may occur during pushback and/or maintenance towing operations with the tested airplane/tow vehicle combination. This document specifies general test requirements and a test evaluation procedure for towbarless tow vehicles (TLTV) intended for pushback and maintenance towing only.

J2995_201703
This recommended practice will specify a standard duty cycle and set of conditions for component-level durability testing. The "duty cycle" refers to a set of loading conditions (e.g. torque or pressure and cycling count), and the 'test conditions" refers to environmental conditions such as temperature, humidity, and part conditioning from prior exposure (e.g. heat aging).

ARP6950
This SAE Aerospace Recommended Practice (ARP) provides guidance and interpretation on how to apply the objectives and activities in ARP4754A, “Guidelines for Development of Civil Aircraft and Systems”, to propulsion systems with electronic engine control. As the ARP4754A was developed and written more generally at the aircraft level, guidance will be provided to allocate ARP4754A objectives and activities to each side of the aircraft/engine interface. Using this guidance, certification applicants (aircraft and engine manufacturers) will be able to make proposals to coordinate their activities with their respective authority based on this allocation with the objective of distributing efficiently the compliance demonstration efforts between engine and aircraft certification and of avoiding unnecessary duplication of work.

This handbook provides "how to" guidance to industry and government for the reliability Activities and Methods contained in ANSI/GEIA-STD-0009 for developing reliable products and systems, successfully demonstrating them during test and evaluation, and sustaining them throughout the system/product life cycle. ANSI/GEIA-STD-0009 requires the developers and customer/users working as a team to plan and implement a reliability program that provides systems/products that satisfy the user's requirements and expectations using a systems engineering approach. The four Objectives of ANSI/GEIA-STD-0009 are listed below: Objective 1: Understand Customer/User Requirements and constraints. The team (developer, customer, and user), includes the Activities necessary to ensure that the user's requirements and product needs are fully understood and defined, so that a comprehensive design specification and Reliability Program Plan are generated. Objective 2: Design and redesign for reliability.
