The FAA is proposing expanded safety requirements for all Boeing 787 Dreamliner variants (787-8, 787-9, and 787-10). This updates a 2019 directive about leading edge slat issues and icing conditions, requiring additional checks and potential flight manual revisions. This affects airlines worldwide that operate Boeing 787s, maintenance providers, and Boeing. The 787 is one of the most widely used widebody jets, so any new airworthiness requirements have significant operational and financial implications for the airline industry.
