What to do
Operators of Airbus A330-223F and A330-243F aircraft must perform detailed inspections and functional tests of the OCCDS flexible hoses within 1,600 flight hours from 18 February 2019 and repeat every 1,600 flight hours thereafter. Any damaged or leaking hoses must be replaced with serviceable parts before the next flight. Installation of affected parts is only allowed if they are new and serviceable according to the Airbus Service Bulletin A330-35-3054.
Summary
EASA Airworthiness Directive 2019-0027 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting Airbus A330-223F and A330-243F freighter aeroplanes. It addresses the inspection and replacement of flexible hoses in the Oxygen Crew and Courier Distribution System (OCCDS) to prevent oxygen leakage. The directive mandates repetitive detailed inspections and functional testing of specific part numbers of flexible hoses and requires replacement if any damage or leakage is found.
What changed
EASA Airworthiness Directive 2019-0027 introduces mandatory repetitive inspections and functional tests of the OCCDS flexible hoses on Airbus A330 freighter aircraft. It requires replacement of any affected hose showing damage or leakage before further flight. This AD is a new regulation focused on mitigating the risk of oxygen leakage from specific flexible hoses in the OCCDS.
Why it matters
This directive is critical for aviation professionals as it addresses a safety risk that could lead to oxygen leakage, potentially causing cockpit crew injury and reduced aircraft control during flight. Operators and maintenance organizations must ensure compliance to maintain aircraft airworthiness and safety. Failure to comply could result in unsafe flight conditions and regulatory penalties.
