Grand Canyon National Park Quiet Aircraft Technology Incentive: Seasonal Relief From Allocations in the Dragon and Zuni Point Corridors

On November 10, 2014, the Federal Aviation Administration (FAA) and the National Park Service (NPS) published in the Federal Register [79 FR 66763-66765] a notice of the agencies' proposal to provide a quiet aircraft technology incentive for commercial air tour operators at Grand Canyon National Park and a request for public comments. Specifically, the agencies proposed to provide seasonal relief from allocations in the Dragon and Zuni Point corridors for commercial air tour operators that convert or have converted to quiet aircraft technology. The FAA and the NPS have reviewed and considered all comments, and have decided to proceed with implementation of the incentive as proposed. This notice describes that decision and responds to the substantive comments received.
