                                 A BILL


 
   To direct the Transportation Security Administration to carry out 
  covert testing and risk mitigation improvement of aviation security 
                  operations, and for other purposes.

    Be it enacted by the Senate and House of Representatives of the 
United States of America in Congress assembled,

SECTION 1. SHORT TITLE.

    This Act may be cited as the ``Aviation Risk Mitigation and 
Security Act'' or the ``ARMS Act''.

SEC. 2. TSA COVERT TESTING AND RISK MITIGATION IMPROVEMENT.

    (a) In General.--Not later than 180 days after the date of the 
enactment of this Act, the Administrator of the Transportation Security 
Administration (TSA) shall establish the following to strengthen 
aviation security operations:
            (1) In accordance with subsection (b), a system for 
        conducting risk-informed, headquarters-based covert testing 
        project scenarios for aviation security operations, including 
        relating to airport passenger and baggage security screening 
        operations, that can yield statistically valid data that can be 
        utilized to identify and assess the nature and extent of any 
        vulnerabilities to such operations that are not mitigated by 
        current security operations.
            (2) A long-term headquarters-based covert testing program, 
        employing static but risk-informed threat vectors, based on 
        annual risk assessments of emerging threats, designed to assess 
        the effectiveness of aviation security operations on an annual 
        basis.
    (b) Methodology.--The Administrator of the TSA shall conduct the 
risk-informed, headquarters-based covert testing project scenarios for 
aviation security operations under paragraph (1) of subsection (a) 
based on annual risk assessments of emerging threats. The Administrator 
shall--
            (1) conduct not fewer than three such covert testing 
        project scenarios to identify any systemic vulnerabilities in 
        aviation security operations, and ensure that each Category X 
        airport in the United States is included in such covert testing 
        project scenarios at least once per fiscal year; and
            (2) document the methodology, assumptions, and rationale 
        guiding the selection and execution of such covert testing 
        project scenarios to ensure statistical validity and actionable 
        results.
    (c) Mitigation.--
            (1) In general.--The Administrator of the TSA shall 
        establish a process to address and mitigate any vulnerabilities 
        to aviation security operations identified and assessed 
        pursuant to the covert testing project scenarios conducted 
        under paragraph (1) of subsection (a).
            (2) Analysis.--Not later than 90 days after identifying a 
        vulnerability referred to in paragraph (1), the Administrator 
        of the TSA shall conduct a root cause analysis to determine the 
        origin and contributing factors relating to such vulnerability.
            (3) Determination.--Not later than 150 days after 
        conducting the analysis under paragraph (2), the Administrator 
        of the TSA shall make a determination regarding whether or not 
        to mitigate the vulnerability referred to in such paragraph, 
        and shall prioritize mitigating such vulnerability based on the 
        ability to reduce risk. If the Administrator determines--
                    (A) to not mitigate such vulnerability, the 
                Administrator shall document the justification relating 
                thereto; or
                    (B) to mitigate such vulnerability, the 
                Administrator shall establish and document--
                            (i) key milestones appropriate for the 
                        level of effort required to so mitigate such 
                        vulnerability; and
                            (ii) a date by which measures to so 
                        mitigate such vulnerability shall be 
                        implemented by the TSA.
            (4) Retesting.--Not later than 180 days after the date on 
        which measures to mitigate a vulnerability are completed by the 
        TSA pursuant to paragraph (3)(B)(ii), and to the extent 
        applicable, the Administrator of the TSA shall conduct a covert 
        testing project scenario in accordance with subsection (a)(1) 
        for the aviation security operation with respect to which such 
        vulnerability was identified to assess the effectiveness of 
        such measures to mitigate such vulnerability.
    (d) Annual Reporting.--
            (1) Compilation of test results.--Not later than November 
        30 of the first full fiscal year that begins after the date of 
        the enactment of this Act and annually thereafter, the 
        Administrator of the TSA, in consultation with the Secretary of 
        Homeland Security, shall produce a report detailing the results 
        of all covert testing project scenarios for aviation security 
        operations under subsection (a)(1) conducted in the immediately 
        preceding fiscal year by the TSA. Each such report shall--
                    (A) be submitted in unclassified form, but may 
                contain a classified annex in accordance with paragraph 
                (2); and
                    (B) include--
