## Abstract

This action stays the effective date for the implementation of the Airspace Modification final rule for the east end of the Grand Canyon National Park (GCNP) until February 20, 2011. In a case decided in August 2002, the U.S. Court of Appeals for the District of Columbia Circuit returned the GCNP rules to the FAA for further consideration of ways to ensure the substantial restoration of natural quiet. After several attempts in resolving the routes issue in the east end, in February 2003, the FAA stayed the east end routes and airspace changes until February 20, 2006. Because of an ongoing mediation action, which involves consideration of the routes in the east end of the GCNP, the FAA finds it necessary to extend the date for the effectiveness of the Airspace Modification rule for the east end until February 20, 2011.
