Federal Aviation Administration March 14, 2024 – Federal Register Recent Federal Regulation Documents

The FAA is adopting a new airworthiness directive (AD) for all ATR-GIE Avions de Transport R[eacute]gional Model ATR42 and ATR72 airplanes. This AD was prompted by a report of incorrect marking and assembly of the two-way valves for the left- and right-hand engine fire extinguishing systems. This AD requires accomplishing a functional check of an affected part; replacing an affected part if necessary; reporting the functional check results; and prohibiting the installation of affected parts; as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

This action extends the comment period for the NPRM titled ``Disclosure of Safety Critical Information'' that was published on January 25, 2024. In that document, the FAA proposed the implementation of certain mandates in the Aircraft Certification, Safety, and Accountability Act of 2020 by requiring applicants for, and holders of, new and amended transport category airplane type certificates to submit, and subsequently continue to disclose, certain safety critical information to the FAA. The FAA also proposed a requirement for all applicants for type certificates, including new, amended, and supplemental type certificates, to submit a proposed certification plan to the FAA. The FAA is extending the comment period closing date, on request, to allow commenters additional time to analyze the proposed rule and prepare a response.
