The Federal Aviation Administration (FAA) has issued a final rule regarding Embraer S.A. Model ERJ 190-400 airplanes, replacing a previous directive due to the need for updated compliance requirements. The new rule addresses an unsafe condition caused by unexpected wear on the wing hinge bearing assembly of the ailerons, which could lead to excessive backlash and limit cycle oscillation, reducing airplane controllability. The FAA's action follows a related directive from the Agência Nacional de Aviação Civil (ANAC) in Brazil, and comments on the rule are being accepted until February 28, 2025. This rule is effective from January 29, 2025.
Simple Explanation
The FAA made a new rule to make sure some Embraer airplanes are safe by checking and fixing parts that help control where the plane goes. They got advice from a group in Brazil, and people can share their thoughts about it until February 28, 2025.
