AD 2025-17-15 Airworthiness Directives; ATR-GIE Avions de Transport Régional Airplanes
Models named: ATR42-500, ATR72-212A. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to ATR—GIE Avions de Transport Régional Model ATR42-500 and ATR72-212A airplanes, certificated in any category, as identified in European Union Aviation Safety Agency (EASA) AD 2025-0103, dated May 5, 2025 (EASA AD 2025-0103).
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, EASA AD 2025-0103.
Unsafe condition
This AD was prompted by a finding that dispatch with a failed main hydraulic pump under the provisions of a certain master minimum equipment list (MMEL) item, combined with failure of the emergency bus, could lead to multiple system losses, including loss of the only remaining hydraulic pump and nose wheel steering and complete loss of control of the rudder travel limitation unit (TLU). The FAA is issuing this AD to address these multiple system losses, which could result in reduced controllability of the airplane on the ground during landing.
Affected ADs
None.
