        enactment of this Act, the Secretary shall submit to the 
        Administrator recommendations regarding actions necessary--
                    (A) to protect public health and safety from 
                adverse effects associated with aircraft overflights at 
                any national park;
                    (B) to protect the resources of any national park 
                experiencing an adverse impact associated with noise 
                from aircraft overflights;
                    (C) to preserve natural quiet at any national park 
                where natural quiet is a part of the park's natural 
                resources and experience; and
                    (D) to prevent resource impairment from noise 
                associated with overflights at any national park.
            (2) Restoration or preservation of quiet.--The 
        recommendations shall provide for--
                    (A) protection of public health and safety from 
                adverse affects associated with aircraft overflights; 
                and
                    (B) substantial restoration of the natural quiet or 
                substantial preservation of the natural quiet and 
                experience of the park.
            (3) Flight-free zones, flight restrictions, and flight 
        bans.--
                    (A) In general.--The recommendations shall include 
                proposals for flight-free zones, for appropriate flight 
                restrictions, or for banning flights within certain 
                national parks as necessary to meet the goals of 
                paragraph (2).
                    (B) Administration and emergency operations.--
                Flight-free zones and flight bans shall provide for 
                flight free areas over a national park, except for 
                purposes of administration, emergency operations, and 
                operations required for transportation of persons and 
                supplies to and from Indian reservations adjacent to 
                any affected national park.
                    (C) Military and other public operations.--The 
                recommendations may exempt noncommercial general 
                aviation, military, and other public operations from 
                proposed flight-free zones, flight restrictions, or 
                proposals banning flights within a park.
                    (D) Flight restrictions.--Flight restrictions, 
                including curfews and limitations on the number of 
                flights in a park may be contained in proposed 
                regulations if necessary to preserve, protect, or

            (4) Prioritization of parks for implementation of 
        recommendations.--The recommendations shall include a proposal 
        for prioritizing the scheduled implementation of plans 
        regulating overflights in the national parks based on the 
resource impairment--
                    (A) caused by overflights in the national parks; or
                    (B) threatened by the introduction or increase of 
                overflights in the national parks.
            (5) Flight altitudes.--The Administrator, after 
        consultation with the Secretary, may--
                    (A) establish minimum flight altitudes to include 
                in the recommendations; and
                    (B) prohibit overflights below such minimum 
                altitudes in any national park as necessary to meet the 
                requirements of paragraph (2).
            (6) Quiet aircraft technology.--The recommendations shall 
        include a joint proposal by the Secretary and the Administrator 
        that--
                    (A) provides incentives for the use of quiet 
                aircraft technology within a national park;
                    (B) creates a schedule for any commercial air tour 
                operator operating within a national park to convert 
                the operator's fleet to quiet aircraft;
                    (C) promotes other appropriate steps to encourage 
                use of quiet aircraft within a national park; or
                    (D) explains why implementation of subparagraphs 
                (A), (B), and (C) is not necessary or appropriate to

        traffic in the airspace above any national park--
                    (A) experiencing an adverse impact associated with 
                noise from aircraft overflights; or
                    (B) for which the Secretary determines that air 
                tours need to be regulated in order to prevent resource 
                impairment from overflights.
            (2) Review of recommendations.--
                    (A) In general.--The plan shall provide for 
                implementation of the recommendations of the Secretary

                would adversely affect aviation safety.
                    (B) Review of recommendations.--If the 
                Administrator determines that implementing the 
                recommendations would adversely affect aviation safety,

Summary: National Parks Overflights Act of 1997 - Directs the Secretary of the Interior to submit to the Administrator of the Federal Aviation Administration recommendations (including a joint proposal for incentives for the use of quiet aircraft technology and a schedule for commercial air tour fleet conversion to such technology) for actions necessary to protect public health and safety and natural resources from adverse effects associated with aircraft overflights at national parks. 
Authorizes the Administrator to:  (1) establish minimum flight altitudes to include in the recommendations; and (2) prohibit overflights below such minimum altitudes in any national park to restore or preserve quiet. 
Directs the Administrator, after receipt of recommendations and notice and opportunity for hearing, to issue a final plan for the management of air traffic over national parks:  (1) experiencing adverse impacts associated with noise from aircraft overflights; or (2) for which air tours need to be regulated in order to prevent resource impairment from overflights.
