What to do

Operators of affected Airbus aircraft must inspect the hand valve of each affected oxygen cylinder before any maintenance on the cylinder or within 60 days of the AD's effective date, whichever occurs first. If defects are found, the cylinder must be emptied and replaced with a serviceable part before further flight or reinstallation. Additionally, no affected oxygen cylinders may be installed on any aircraft from the effective date onward.

Summary

EASA Airworthiness Directive 2019-0085 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting various Airbus aeroplanes including the A300, A310, A318, A319, A320, A321, A330 (except A330-223F and A330-243F), and A340 models. The directive addresses inspection and replacement requirements for specific oxygen cylinders with part numbers 89794077, 89794015, and 891511-14 due to a manufacturing defect. This AD mandates inspection of the hand valve assembly on affected oxygen cylinders to prevent oxygen leakage and potential safety hazards.

What changed

EASA Airworthiness Directive 2019-0085 introduces a one-time inspection requirement for affected oxygen cylinders installed on certain Airbus aircraft. It requires replacement of any cylinder found defective during inspection and prohibits installation of affected parts after the effective date. This AD also provides an alternative compliance method allowing replacement of all affected parts within 60 days as a substitute for inspection.

Why it matters

This directive is critical for aviation professionals because it addresses a safety risk involving oxygen system components that could reduce oxygen availability or cause in-flight fire hazards. Operators and maintenance organizations must ensure compliance to maintain aircraft airworthiness and passenger safety. Non-compliance could lead to operational restrictions or increased risk during depressurization events or ground testing.
