Modification of the Dimensions of the Grand Canyon National Park Special Flight Rules Area and Flight Free Zones

This action amends special operating rules and airspace for those persons operating aircraft in the area designated as the Grand Canyon National Park Special Flight Rules Area (SFRA). Specifically, this action modifies the eastern portion of the SFRA and the Desert View Flight-free Zone (FFZ); establishes a corridor through the Bright Angel FFZ for future noise efficient/quiet technology aircraft; and modifies the Sanup FFZ to provide for a commercial route over the northwestern section of the Grand Canyon National Park (GCNP). In addition, this action makes editorial corrections to several previously issued special operating rules for this affected area. The FAA is taking this action to assist the National Park Service in fulfilling the statutory mandate of substantially restoring the natural quiet and experience in GCNP.
