SECTION 1. SHORT TITLE.

    This Act may be cited as the ``Silent Skies Act of 2015''.

SEC. 2. FINDINGS.

    Congress finds that--
            (1) aircraft and airport noise is one of the most common 
        ``quality of life'' nuisance issues in neighborhoods throughout 
        the United States; and
            (2) the chapter 14 aircraft noise certification standard 
        (to be known as stage 5) became applicable to new type design 
        aircraft in 2014 pursuant to an agreement signed by the 
        International Civil Aviation Organization, of which the United 
        States is a member.

SEC. 3. AIRCRAFT NOISE REDUCTION TECHNOLOGY RESEARCH, DEVELOPMENT, AND 
              IMPLEMENTATION PARTNERSHIP.

    (a) Cooperative Agreement.--Subchapter I of chapter 475 of title 
49, United States Code, is amended by adding at the end the following:

    ``(a) In General.--The Administrator of the Federal Aviation 
Administration shall enter into a cooperative agreement, using a 
competitive process, with an institution, entity, or consortium to 
carry out a program for the development, maturing, and certification of 
aircraft technology that will assist in-service and in-production civil 
turbojets that have noise levels greater than the levels specified in 
stage 4 noise standards in complying with such noise standards, as 
required under subchapter II of this chapter, or more stringent noise 
standards.

        on a cost-shared basis, using Federal and non-Federal funds; 
        and
            ``(2) to make repayments to the United States of all or a 
        portion of the amounts received by the recipient under the 
        cooperative agreement, if an aircraft technology developed 
        under the cooperative agreement results in revenues for the 
        recipient.
    ``(c) Funding.--Of amounts appropriated under section 48102(a), not 
more than $10,000,000 for each of fiscal years 2017, 2018, and 2019 may 
be used to carry out this section.
    ``(d) Report.--Beginning in fiscal year 2017, the Administrator 
shall publish an annual report on the program established under this 
section until completion of the program.''.
    (b) Clerical Amendment.--The analysis for such subchapter is 
amended by adding at the end the following:

SEC. 5. STANDARDS FOR ISSUANCE OF TYPE CERTIFICATES.

    (a) Applicability of Stage 5 Noise Standards to Civil Turbojets 
With a Maximum Weight of More Than 75,000 Pounds.--On and after 
December 31, 2017, the Secretary of Transportation may not issue a type 
certificate for a civil turbojet with a maximum weight of more than 
75,000 pounds unless the person applying for the type certificate 
demonstrates that the civil turbojet complies with stage 5 noise 
levels.
    (b) Applicability of Stage 5 Noise Standards to All Civil 
Turbojets.--On and after December 31, 2020, the Secretary may not issue 
a type certificate for any civil turbojet unless the person applying 
for the type certificate demonstrates that the civil turbojet complies 
with stage 5 noise levels.
Silent Skies Act of 2015  This bill directs the Federal Aviation Administration to enter into a competitive cooperative agreement with an institution, entity, or consortium to carry out a program for the development of aircraft technology that will assist in-service and in-production civil turbojets not meeting stage 4 noise standards to comply with those or more stringent standards. The Department of Transportation (DOT) must: (1) issue regulations to establish minimum standards to ensure that graduated percentages of civil turbojets weighing over 75,000 pounds comply with the stage 4 noise levels by specified dates, and (2) report annually on the progress made by air carriers in complying with such standards. 100% of such turbojets operating after December 31, 2037, must comply with stage 4 levels. DOT shall request the International Civil Aviation Organization to add to its Work Programme the consideration of international standards for the phase-out of aircraft that do not comply with stage 4 noise levels. The requirements of this Act shall not apply to civil turbojet aircraft that operate outside of the 48 contiguous states. DOT may not issue a type certificate for: (1) a civil turbojet with a maximum weight of more than 75,000 pounds on and after December 31, 2017, unless the applicant demonstrates that such turbojet complies with stage 5 noise levels; and (2) any civil turbojet on and after December 31, 2020, unless the applicant demonstrates that such turbojet complies with stage 5 noise levels.
