FAA Patches Typos in 25-Hour Airplane Black Box Mandate
Published Date: 5/8/2026
Rule
Summary
The FAA fixed some typos and formatting goofs in the new rule that requires future-built airplanes to have cockpit voice recorders that record 25 hours instead of just 2. These corrections don’t change the rule itself but make sure the official text is clear and accurate. The fixes take effect on May 8, 2026, and mainly affect aircraft manufacturers and operators following these updated rules.
