Full Description

This SAE Aerospace Recommended Practice (ARP) is intended to provide guidance on verifying the integrity of inflation pressure sealing systems of aircraft wheel/tire assemblies.

Aircraft wheel/tire assemblies can maintain inflation integrity only if the entire sealing system, consisting of the tire, wheel, inflation valve, over pressure relief devices, pressure monitoring systems , valve caps, gauges, fuse plugs, O-rings, seal glands and interfaces/boundaries between these components, successfully contains the tire inflation gas.

This document is to be used as a guide for sealing system validation when new design concepts not proven in service are being employed. It may also be used for evaluating alternate design approaches, material changes and trouble shooting service problems. The design of the sealing system and the need for verification testing are left to the discretion of the wheel manufacturer, and the cognizant wheel design and configuration controller.

This document is not intended to be a new qualification/certification standard.
