The Federal Aviation Administration (FAA) has established a new rule for ATR—GIE Avions de Transport Régional Model ATR42 and ATR72 airplanes. This rule requires replacing faulty Angle of Attack (AoA) probes that may not activate the stick pusher, a safety mechanism, in a timely manner, especially at low airspeeds and when flaps are extended. This condition could potentially lead to a loss of airplane control. The rule, effective April 4, 2025, aligns with a directive from the European Union Aviation Safety Agency (EASA) and prohibits installing the affected parts in these aircraft.
Simple Explanation
The FAA wants some airplanes to change a part called the Angle of Attack (AoA) probe because it doesn't work well and might make the plane harder to control. This change makes the planes safer when they fly slowly and with flaps open.
