Independently verified. Duckworth is the SOLE SPONSOR (zero cosponsors) of S.2332, the Experienced Pilots Save Lives Act of 2023, which she authored and introduced July 18, 2023 specifically to strengthen the quality of flight hours required under the 1,500-hour rule. Her official press release contains the verbatim promise language. Beyond sponsorship, as Chair of the Senate Aviation Safety Subcommittee she drove the effort through hearings, floor speeches, and by securing commitments from FAA/DOT nominees (Phil Washington, Sean Duffy) to uphold the rule. However, the standalone bill died in committee (last action: read twice and referred to Commerce Committee; never marked up, voted, or enacted). The 1,500-hour rule was ultimately only MAINTAINED (not strengthened) via the Langworthy amendment in the FAA Reauthorization Act of 2024 (passed 387-26) — her affirmative 'strengthen the quality of flight hours' provisions never became law, so credit above CHAMPIONED (PARTIAL/FULL) is not warranted. Being lead/sole sponsor plus active subcommittee-chair advocacy is well beyond a single supporting vote, which distinguishes this from ATTEMPTED and squarely fits CHAMPIONED. Applying the same standard neutrally: any senator who is sole sponsor of a named bill and actively drives related hearings/advocacy, yet whose bill dies in committee, would earn CHAMPIONED regardless of party. Prior rating and sources verified as real and on point; verdict stands.
