Abstract: A valve stem access system including a valve stem access assembly for an aircraft wheel cover is provided. One variation of the valve stem access system is designed for installation on a surface of an aircraft wheel fairing or pant and includes an installation template and positioning and cutting guide for accurate location and attachment of a valve stem access assembly that provides easy access to the aircraft wheel tire valve stem through a movable access panel. An alignment and indicator guide provides visual confirmation that the valve stem is correctly aligned with the access assembly. In another variation, a valve stem access assembly for an aircraft wheel hub cover is also provided.
