What to do
Operators must perform a special detailed inspection of affected engine air inlet cowls within 78 months after 20 March 2024 or 144 months since the aircraft reference date, whichever occurs first, but only after the affected part has accumulated at least 2,000 flight cycles. If discrepancies are found, corrective actions must be taken before the next flight. Inspection results must be reported to Collins Aerospace within 30 days. Installation of affected parts is allowed only if they have been inspected and corrected as required.
Summary
EASA Airworthiness Directive 2025-0283 is a corrective AD addressing inspection requirements for the air intake cowl on Airbus A350-941 and A350-1041 aeroplanes. It mandates special detailed inspections of affected engine air inlet cowls with specific part numbers to detect elongation of locating holes that could impair nacelle anti-icing performance. The AD applies to all serial numbers of the affected parts installed on these aircraft models.
What changed
This AD supersedes EASA AD 2024-0060R1 and updates the inspection threshold by introducing a minimum value of 2,000 flight cycles before inspection to ensure high confidence in detecting discrepancies. It also corrects typographical errors in the previous AD and updates reference publication dates. The inspection compliance times and reporting requirements have been clarified accordingly.
Why it matters
This directive is critical for maintaining the safety and airworthiness of Airbus A350 aircraft by preventing potential loss of nacelle anti-icing protection, which could lead to loss of control. Operators and maintenance organizations must ensure timely inspections and corrective actions to avoid unsafe conditions. Compliance with this AD ensures regulatory adherence and continued operational safety.
