Sec. 47509. Research program on quiet aircraft technology for 
        propeller and rotor driven aircraft
        
    (a) Establishment.--The Administrator of the Federal Aviation 
Administration and the Administrator of the National Aeronautics and 
Space Administration shall conduct a study to identify technologies for 
noise reduction of propeller driven aircraft and rotorcraft.
    (b) Goal.--The goal of the study conducted under subsection (a) is 
to determine the status of research and development now underway in the 
area of quiet technology for propeller driven aircraft and rotorcraft, 
including technology that is cost beneficial, and to determine whether a 
research program to supplement existing research activities is 
necessary.
    (c) Participation.--In conducting the study required under 
subsection (a), the Administrator of the Federal Aviation Administration 
and the Administrator of the National Aeronautics and Space 
Administration shall encourage the participation of the Department of 
Defense, the Department of the Interior, the airtour industry, the 
aviation industry, academia and other appropriate groups.
    (d) Report.--Not less than 280 days after August 23, 1994, the 
Administrator of the Federal Aviation Administration and the 
Administrator of the National Aeronautics and Space Administration shall 
transmit to Congress a report on the results of the study required under 
subsection (a).
    (e) Research and Development Program.--If the Administrator of the 
Federal Aviation Administration and the Administrator of the National 
Aeronautics and Space Administration determine that additional research 
and development is necessary and would substantially contribute to the 
development of quiet aircraft technology, then the agencies shall 
conduct an appropriate research program in consultation with the 
entities listed in subsection (c) to develop safe, effective, and 
economical noise reduction technology (including technology that can be 
applied to existing propeller driven aircraft and rotorcraft) that would 
result in aircraft that operate at substantially reduced levels of noise 
to reduce the impact of such aircraft and rotorcraft on the resources of 
national parks and other areas.
