What to do
Operators must amend the Aircraft Flight Manual before the next flight after 18 August 2022 to incorporate new limitations and inform flight crews accordingly. Dispatch of affected aircraft is prohibited under specified Master Minimum Equipment List items from the effective date. Additionally, any bleed fault maintenance messages must be reported to Airbus before the next flight for further instructions.
Summary
EASA Airworthiness Directive 2022-0170-E is an emergency directive affecting Airbus A330-841 and A330-941 aeroplanes. It addresses issues related to leaking Bleed System High Pressure Valves (HPV) that may cause damage to the Pressure Regulating Valve and potentially lead to loss of aircraft control. The directive mandates amendments to the Aircraft Flight Manual and imposes dispatch restrictions to mitigate the risk.
What changed
This new emergency directive introduces mandatory amendments to the Aircraft Flight Manual to include additional operational limitations and enforces dispatch restrictions on specific Master Minimum Equipment List items related to the bleed air system. It also requires operators to report certain maintenance faults to Airbus for further instructions. The directive is an interim measure pending further regulatory action.
Why it matters
This directive is critical for aviation professionals as it addresses a safety risk that could lead to high pressure and temperature damage in the bleed air system, potentially causing duct bursts and loss of aircraft control. Operators and maintenance teams must comply promptly to ensure continued airworthiness and safe operation of affected Airbus A330 models. Compliance helps prevent in-flight failures and supports regulatory adherence.
