EASA AD 2022-0156
Pneumatic — Bleed Gimbals at Wing to Pylon Interfaces — Modification
Summary
EASA Airworthiness Directive 2022-0156 is an airworthiness directive addressing a welding quality issue in the bleed gimbals at the wing to pylon interfaces on Airbus A350-941 and A350-1041 aeroplanes. The affected parts include specific bleed duct assemblies and bleed gimbals with certain part numbers manufactured before week 51 of 2016. This directive mandates inspection and replacement of affected parts to prevent hot bleed air leakage and potential structural damage.
What Changed
EASA Airworthiness Directive 2022-0156 supersedes the previous AD 2020-0169R1 and introduces additional requirements for physical inspection of bleed gimbals on Group 2 aeroplanes to identify affected parts that may not have maintenance records. It retains the replacement requirements of the previous AD and prohibits installation of affected parts on all aeroplanes.
Why It Matters
This directive is critical for aviation professionals as it addresses a potential safety risk involving hot bleed air leakage that could compromise the pneumatic system and wing structural integrity. Operators and maintenance organizations must ensure compliance to maintain aircraft airworthiness and prevent possible in-flight failures related to bleed gimbal defects.
What To Do
Operators of Airbus A350-941 and A350-1041 aeroplanes must inspect bleed gimbals on Group 2 aeroplanes before exceeding 5,600 flight cycles since manufacture and replace any affected parts with serviceable ones. Group 1 aeroplanes must replace affected parts before 5,600 flight cycles. Installation of affected parts is prohibited from 26 August 2020 onward.
