SUPERSEDED BY EASA AD 2025-0110
Summary
EASA Airworthiness Directive 2023-0125 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting ATR 42-500 and ATR 72-212A aeroplanes. It mandates a one-time detailed inspection of the horizontal stabilizer front and centre box areas to detect loose fasteners and cracks that could compromise structural integrity. The directive applies to specific manufacturer serial numbers as listed in the applicable service bulletins.
What Changed
This new airworthiness directive introduces mandatory inspections of the horizontal stabilizer's left and right leading edge lateral ribs, the box in between, the centre box upper panel, and the forward back-up fitting. It requires operators to perform a detailed inspection within 24 months of the effective date and to carry out corrective actions if discrepancies are found. The directive is based on reports of manufacturing errors and structural issues identified in service.
Why It Matters
This directive is critical for maintaining the structural integrity and safety of affected ATR 42 and ATR 72 aircraft. Aviation professionals, including operators and maintenance organizations, must comply to prevent potential failures caused by loose fasteners or cracks in the horizontal stabilizer. Compliance ensures continued airworthiness and regulatory adherence, reducing the risk of in-flight structural issues.
What To Do
Operators of ATR 42-500 and ATR 72-212A aircraft must perform a detailed inspection of the specified horizontal stabilizer areas within 24 months from 2023-07-06, following the instructions in ATR Service Bulletins ATR42-55-0020 or ATR72-55-1013. If any discrepancies are found, they must contact ATR for approved repair instructions and complete repairs before the next flight or within the specified compliance time. Alternative methods of compliance may be approved upon request.
