## Abstract

This amendment removes an obsolete reference in Special Federal Aviation Regulation 50-2, Special Flight Rules in the Vicinity of Grand Canyon National Park, AZ. In section 9 of that SFAR, there is a "Note" that refers to an informational map of the Special Flight Rules Area (SFRA). This map is no longer available; however, there is an illustrational map of the SFRA in Part 93, Subpart U. Therefore, this technical amendment deletes the reference in SFAR 50-2, which is no longer needed and is confusing to the public.
