What to do
Operators of Airbus A350-941 and A350-1041 aeroplanes must replace the affected low pressure hydraulic pipes within the specified compliance times, which range from before exceeding 6 years since the aeroplane's date of manufacture to specific flight cycle limits, or within 10 months after the AD revision effective date, whichever is later. Additionally, from 18 November 2022, no affected parts may be installed on any aeroplane. Maintenance teams should follow the Airbus Service Bulletins referenced in the AD for replacement procedures.
Summary
EASA Airworthiness Directive 2022-0217R1 is a regulatory update addressing the replacement of low pressure hydraulic pipes in the nose landing gear pressure return lines on Airbus A350-941 and A350-1041 aeroplanes. The directive mandates the removal and replacement of affected hydraulic pipes identified by specific part numbers due to corrosion and ovality issues. This directive applies to all manufacturer serial numbers of the specified Airbus A350 models.
What changed
EASA Airworthiness Directive 2022-0217R1 revises the original AD 2022-0217 by extending certain compliance times for the replacement of affected hydraulic pipes. The revision updates the compliance schedule in Table 2 and clarifies installation restrictions for affected parts. It incorporates additional information provided by Airbus to support these extended compliance deadlines.
Why it matters
This directive is critical for aviation professionals because the affected hydraulic pipes have quality defects that could lead to premature rupture, potentially compromising aircraft controllability. Operators and maintenance organizations must ensure timely replacement to maintain airworthiness and comply with regulatory requirements. Failure to comply could result in operational restrictions or safety risks.
