EASA AD 2025-0110
Stabilizers — Horizontal Stabilizer Front Box, Centre Box and Front Spar Web — Inspection
Summary
EASA Airworthiness Directive 2025-0110 is an airworthiness directive affecting ATR 42-500 and ATR 72-212A aeroplanes. It mandates inspections of the horizontal stabilizer front box, centre box, front spar web, and related structural components to detect loose fasteners and cracks. The directive applies to specific manufacturer serial numbers as listed in ATR service bulletins.
What Changed
EASA Airworthiness Directive 2025-0110 supersedes AD 2023-0125 and expands its applicability to additional aircraft serial numbers. It also introduces inspections of additional affected areas within the horizontal stabilizer structure that were not covered in the previous AD. The directive requires compliance with updated ATR service bulletins providing detailed inspection instructions.
Why It Matters
This directive is critical for maintaining the structural integrity of the horizontal stabilizer on affected ATR 42 and ATR 72 aircraft. Detecting and correcting loose fasteners or cracks prevents potential structural failures, ensuring continued airworthiness and safety. Operators, maintenance organizations, and compliance teams must adhere to these inspections to avoid regulatory non-compliance and mitigate safety risks.
What To Do
Operators of affected ATR 42-500 and ATR 72-212A aeroplanes must perform a one-time detailed inspection of the specified horizontal stabilizer areas within 24 months of the effective date of this AD or as specified for their group. If discrepancies are found, approved repair instructions from ATR must be followed before the next flight. Compliance with the latest ATR service bulletins ATR42-55-0020, ATR72-55-1013, ATR42-55-0025, and ATR72-55-1018 is required.
