Description / Abstract:
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.
Purpose:
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.
