Description:  This action extends the comment period for the NPRM titled "Disclosure of Safety 
Critical Information'' that was published on 25 January 2024. In that document, the Federal Aviation 
Administration (FAA) proposed the implementation of certain mandates in th e 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 certifi cates, 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.  
The comment period for the NPRM published on 25 January 2024, at 89 FR 4841 , is extended. 
Comments should be received on or before 9 May 2024.
