EASA AD 2018-0229R1
Wings — Centre Wing Box Frame 47 Angle Fittings — Inspection / Modification
Summary
EASA Airworthiness Directive 2018-0229R1 is a regulatory update addressing inspection and modification requirements for the centre wing box frame 47 angle fittings on Airbus A300-600 series aeroplanes. This directive applies to various A300-600 models except those already modified by Airbus Service Bulletin A300-57-6069. It mandates specific inspections and modifications to detect and correct cracks that could compromise the structural integrity of the aircraft's centre wing box.
What Changed
EASA AD 2018-0229R1 revises the previous AD 2018-0229 by removing Airbus A300-600ST aeroplanes from the applicability and updating inspection thresholds and intervals for different groups of A300-600 aeroplanes. It retains prior inspection and modification requirements while refining compliance timelines and inspection methods based on recent findings and Airbus service bulletin revisions.
Why It Matters
This directive is critical for aviation professionals to ensure the structural safety of Airbus A300-600 aeroplanes by preventing undetected cracks in the centre wing box frame 47 angle fittings. Operators and maintenance organizations must comply to maintain airworthiness and avoid potential structural failures. The updated inspection schedules and modification requirements help optimize maintenance planning and ensure regulatory compliance.
What To Do
Operators of affected Airbus A300-600 aeroplanes must perform cold expansion modifications on angle fitting attachment holes before exceeding specified flight cycles or hours, and conduct repetitive high frequency eddy current and ultrasonic inspections as detailed in the directive. Compliance deadlines vary by aircraft group and flight time, with grace periods defined in the applicable Airbus service bulletins. Maintenance teams should follow the latest Airbus service bulletin revisions referenced in the AD for inspection and modification procedures.
