What to do
Operators must amend the Airplane Flight Manual within 7 days after 5 September 2022 by incorporating the specified temporary revision and update the Master Minimum Equipment List concurrently. They must perform seal integrity tests and inspections before the next flight after specified events and replace HPV clips before exceeding 4,000 flight hours or within 1,500 flight hours after 5 September 2022, whichever is later. Any discrepancies found during inspections must be corrected before further flight, and failures must be reported to Airbus within 28 days.
Summary
EASA Airworthiness Directive 2022-0227 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting Airbus A330-841 and A330-941 aeroplanes. It addresses issues related to the engine bleed air system high pressure valve (HPV) clips, specifically Part Number 6764-222, requiring inspections, maintenance, and amendments to the Airplane Flight Manual and Master Minimum Equipment List. The directive aims to prevent potential damage caused by leaking HPV clips that could lead to loss of aircraft control.
What changed
EASA AD 2022-0227 supersedes the previous AD 2022-0181 and introduces additional criteria for the installation and replacement of HPV clips and HPVs. It mandates new maintenance procedures, including repetitive replacement of HPV clips before exceeding 4,000 flight hours and updated troubleshooting and seal integrity tests. The directive also updates the AFM and MMEL to reflect these changes and removes previous temporary limitations.
Why it matters
This directive is critical for aviation professionals as it addresses a safety risk involving potential high-pressure leaks in the engine bleed air system that could cause duct bursts and loss of aircraft control. Operators and maintenance organizations must comply to ensure continued airworthiness and safe operation of affected Airbus A330 models. Compliance helps prevent costly damage and operational disruptions while meeting regulatory requirements.
