Boeing 737 MAX AD NPRM Now Available for Early Public Review

Today, the FAA sent a notice of proposed rulemaking (NPRM) for a Boeing 737 MAX airworthiness directive (AD) (PDF) to the Office of the Federal Register for publication. The NPRM proposes mandating a number of design changes to address an identified unsafe condition. When the NPRM publishes in the Federal Register, a 45 day public comment period will begin. The FAA is posting the NPRM on its website today to enable the public to begin review early.

The FAA will also be placing the Preliminary Summary of the FAA's Review of the Boeing 737 MAX (PDF) in the docket to assist with the review of the proposed AD.
