WTO.美国通报运输类飞机的内部部件和防火部件的法规补遗

机构：联邦航空管理局（FAA）、交通部（DOT）

措施：拟议法规通知（NPRM）；延长评论期

摘要：这项行动延长了2019年7月3日在《联邦公报》上公布的建议法规通知的评论期。在建议法规的通知中，美国联邦航空局提议修改运输类飞机内部舱室防火的某些适航规定。该提案将把这些易燃性法规从详细的规定性要求转变为更简单的、基于性能的标准。该提案将这些标准分为两类：一类是旨在保护飞机及其乘客免受飞行中火灾危害的标准，另一类是旨在保护飞机及其乘客免受坠机后火灾危害的标准。此外，该提案将从法规中删除试验方法，并允许申请人在某些情况下，在不进行试验的情况下，或通过提供拟议材料易燃性特性的独立证据来证明符合性。该提案包括对联邦航空局各项规章的修改。该建议是必要的，以消除不必要的测试，增加标准化，提高安全性。联邦航空局正在延长评论期的截止日期，以便评论人有时间充分分析提案并准备答复。

日期：于2019年7月3日发布（84 FR 31747）并计划于2019年10月1日结束的建议法规的通知的评论期延长至2019年12月。

TITLE: Interior Parts and Components Fire Protection for Transport Category Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT)

ACTION: Notice of proposed rulemaking (NPRM); extension of comment period

SUMMARY: This action extends the comment period for an NPRM that was published in the Federal Register on 3 July 2019. In the NPRM, the FAA proposed to amend certain airworthiness regulations for fire protection of interior compartments on transport category airplanes. The proposal would convert those flammability regulations from detailed, prescriptive requirements into simpler, performance-based standards. The proposal would divide these standards into two categories: those designed to protect the airplane and its occupants from the hazards of in-flight fires, and those designed to protect the airplane and its occupants from the hazards caused by post-crash fires. In addition, the proposal would remove test methods from the regulations and allow applicants, in certain cases, to demonstrate compliance either without conducting tests or by providing independent substantiation of the flammability characteristics of a proposed material. The proposal includes conforming changes to various FAA regulations. The proposal is necessary to eliminate unnecessary testing, increase standardization, and improve safety. The FAA is extending the closing date of the comment period to allow commenters time to adequately analyze the proposal and prepare responses.

DATES: The comment period for the NPRM published on 3 July 2019 (84 FR 31747), and scheduled to close on 1 October 2019, is extended until 2 December 2019.
