What to do
Operators must perform detailed inspections of the OCCDS flexible hoses within 1,600 flight hours after 18 February 2019 and repeat inspections every 1,600 flight hours thereafter. Any damaged or leaking hoses found must be replaced before the next flight with either a serviceable or improved serviceable part. All affected hoses must be replaced with improved serviceable parts within 42 months from 8 May 2020 to terminate repetitive inspections.
Summary
EASA Airworthiness Directive 2020-0092 is an airworthiness directive issued for Airbus A330-223F and A330-243F freighter aeroplanes. It addresses inspection and replacement requirements for flexible hoses in the Oxygen Crew and Courier Distribution System (OCCDS) to prevent oxygen leakage. The directive applies to specific manufacturer serial numbers of these aircraft models.
What changed
This directive supersedes EASA AD 2019-0027 and retains the requirement for repetitive detailed inspections of the OCCDS flexible hoses. It introduces a mandatory replacement of affected flexible hoses with improved serviceable parts within 42 months of the effective date. The directive also prohibits installation of affected parts after modification.
Why it matters
This directive is critical to prevent oxygen leakage from cracked flexible hoses in the OCCDS, which could lead to cockpit crew injury or reduced aircraft control during in-flight depressurization or smoke events. Compliance ensures continued airworthiness and safety of affected Airbus A330 freighter aircraft. Operators and maintenance organizations must monitor and address this potential unsafe condition to avoid operational risks.
