EASA AD 2025-0232
Wings — Centre Section Frame 40 Forward Fitting Radius at Tension Bolt Junction — Inspection / Repair
Summary
EASA Airworthiness Directive 2025-0232 is an airworthiness directive addressing inspection and repair requirements for the centre section frame 40 forward fitting radius at the tension bolt junction on Airbus A300-600ST aeroplanes. It applies specifically to all manufacturer serial numbers of the A300F4-608ST model. The directive mandates ultrasonic and high frequency eddy current inspections to detect cracks and requires corrective actions if damage is found.
What Changed
This directive introduces updated inspection thresholds and intervals for Airbus A300-600ST aeroplanes, particularly distinguishing between pre- and post-modification 19746 configurations. It partially replaces the requirements of EASA AD 2019-0044 for these aircraft and adjusts inspection intervals with an adjustment factor of 0.41 for post-mod 19746 aeroplanes. Concurrently, EASA AD 2019-0044 has been revised to remove applicability to A300-600ST aeroplanes.
Why It Matters
This directive is critical for maintaining the structural integrity of the Airbus A300-600ST wings by ensuring early detection of cracks that could compromise residual strength. Operators and maintenance organizations must comply to prevent extensive repairs and potential safety risks. The updated inspection intervals reflect changes in operational assumptions, impacting maintenance planning and compliance monitoring.
What To Do
Operators of Airbus A300-600ST aeroplanes must perform ultrasonic and high frequency eddy current inspections within specified thresholds and intervals based on aircraft group classification. Any detected cracks within defined limits require corrective actions before further flight, and cracks beyond limits require contacting Airbus for approved instructions. Inspection results must be reported to Airbus within 30 days after each inspection or within one month after the AD's effective date. The effective date for compliance is 2025-11-05.
