FAA Mandates Sensor Replacements on ATR Regional Planes
Published Date: 2/28/2025
Rule
Summary
The FAA is making sure all ATR42 and ATR72 airplanes get safer by fixing a sensor that might not work right at low speeds. Pilots need to replace certain parts to avoid delays in safety features kicking in. This update must happen soon and helps keep flights safe without breaking the bank.
Analyzed Economic Effects
3 provisions identified: 1 benefits, 2 costs, 0 mixed.
Safer Flight Controls for ATR Aircraft
The AD addresses insufficient AoA probe accuracy at low airspeeds that could delay stick pusher activation in a flaps-extended configuration, improving safety on ATR42 and ATR72 airplanes. Passengers and crew on those airplane models benefit from reduced risk of that unsafe condition.
Mandatory AoA Probe Replacement
The FAA requires replacing each affected Angle of Attack (AoA) probe on all ATR42 and ATR72 airplanes with a serviceable part, as specified in the incorporated EASA airworthiness directive. This is a compliance requirement for operators of those airplane models.
Prohibition On Installing Affected Parts
The AD prohibits installing the affected AoA probe parts on ATR42 and ATR72 airplanes, per the incorporated EASA AD. Maintenance providers and parts suppliers must not fit those affected parts going forward.
