✈️Airworthiness Directive for ATR Airplanes Requiring Probe Replacement
Airworthiness Directives; ATR-GIE Avions de Transport Régional Airplanes
Summary
The FAA is adopting a new airworthiness directive (AD) for all ATR--GIE Avions de Transport R[eacute]gional Model ATR42 and Model ATR72 airplanes. This AD was prompted by the insufficient accuracy of a certain Angle of Attack (AoA) probe at low airspeeds which could lead to a delayed activation of the stick pusher in a flaps-extended configuration. This AD requires replacing each affected part with a serviceable part, and also prohibits the installation of affected parts, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

The regulation establishes compliance requirements for airlines operating ATR42 and ATR72 airplanes regarding the replacement of Angle of Attack probes to ensure safety, which may incur significant costs for operators (up to $11.7 million collectively). Compliance costs create a financial implication for related businesses.
