What to do
Operators of ATR 42 and ATR 72 aircraft with affected oxygen cylinders must inspect the hand valve of each cylinder before any maintenance or within 60 days of 2019-06-04. If defects are found, the cylinder must be replaced before the next flight. Additionally, no affected oxygen cylinders may be installed on any aircraft from the effective date onward.
Summary
EASA Airworthiness Directive 2019-0111 is an airworthiness directive issued by the European Union Aviation Safety Agency concerning ATR 42 and ATR 72 aeroplanes. It addresses oxygen cylinders with Part Number 89794077 that may have a manufacturing defect leading to oxygen leakage. The directive mandates inspection and possible replacement of affected oxygen cylinders to ensure safety.
What changed
This directive introduces a one-time inspection requirement for specific oxygen cylinders installed on ATR 42 and ATR 72 aircraft, identifying a manufacturing discrepancy in a batch produced in 2018. It prohibits the installation or reinstallation of affected oxygen cylinders and requires removal and replacement if defects are found during inspection.
Why it matters
This directive is critical for aviation professionals because the affected oxygen cylinders could reduce available oxygen capacity during depressurization events or pose a fire risk during flight or ground testing. Compliance ensures the safety of aircraft occupants and maintenance personnel by preventing potential oxygen leakage and related hazards.
