EASA AD 2025-0107
Fuselage — Frame 35 / Slidebox Junction — Inspection
Summary
EASA Airworthiness Directive 2025-0107 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting Airbus A321-111, A321-112, A321-131, A321-211, A321-212, A321-213, A321-231, and A321-232 aeroplanes. The directive mandates inspections of the fuselage frame 35 and slidebox junction areas to detect cracks that could compromise structural integrity. It applies to all serial numbers except those with Airbus modifications 161341 or 161511 incorporated during production.
What Changed
EASA Airworthiness Directive 2025-0107 supersedes the previous AD 2016-0146R2 and retains its inspection requirements while introducing new optional terminating actions based on updated Airbus service bulletins. It updates the inspection and modification instructions for certain frame 35 locations, reflecting improvements in repair and modification procedures. This AD also clarifies applicability and compliance timelines for repetitive special detailed inspections.
Why It Matters
This directive is critical for maintaining the structural integrity of affected Airbus A321 aircraft by ensuring early detection and correction of fatigue cracks in key fuselage areas. Compliance helps operators and maintenance organizations prevent potential in-flight structural failures, thereby enhancing safety and extending the service life of the fleet. It also provides clear guidance on inspection intervals and approved repair or modification actions, facilitating regulatory compliance and maintenance planning.
What To Do
Operators of affected Airbus A321 models must perform special detailed inspections of the fuselage frame 35 and slidebox junction within specified flight cycle thresholds and repeat inspections every 5,300 flight cycles. If cracks are found, corrective actions must be taken before the next flight following the applicable Airbus service bulletin instructions. Optional terminating modifications can be incorporated to end repetitive inspections, with compliance required by 21 May 2025 or within the specified flight cycle limits.
