The FAA has issued a new rule that affects all Embraer S.A. Model ERJ 190-300 and ERJ 190-400 airplanes due to a failure in the MAU 3B, which can result in brake faults and loss of normal braking. To fix this, the flight manual must be updated to include new procedures. This directive will be effective from April 14, 2025, and is based on a similar measure by Brazil's aviation authority. The FAA seeks public comments by May 12, 2025, but has already taken action to address this safety issue.
Simple Explanation
The government found a problem in some Embraer airplanes where the brakes might not work right because a part inside failed. They're telling people who fly these planes to update their instruction book so they know what to do if this happens, and they're asking people to share their thoughts about these changes by a certain date.
