What to do
Operators must inspect the crew oxygen pipe assemblies to identify batch numbers and replace any affected parts within 7,500 flight hours or 26 months from specified effective dates depending on aircraft group classification. Maintenance records may be reviewed as an alternative to physical inspection if reliable. Installation of affected parts is prohibited from the effective dates stated for each group. Compliance must follow Airbus Service Bulletin A320-35-1069 instructions.
Summary
EASA Airworthiness Directive 2018-0060R1 is a regulatory document addressing corrosion issues in crew oxygen pipe assemblies with Part Number D3511032000640 installed on Airbus A318, A319, A320, and A321 aircraft. The directive mandates inspection and replacement of affected oxygen pipes from specific batch numbers to ensure continued airworthiness and safety of the oxygen supply system for flight crew members. It applies to various manufacturer serial numbers including certain A320 and A321 NEO models.
What changed
This revision expands the applicability to include five A320 and A321 NEO aircraft and clarifies inspection and replacement requirements for additional groups of aircraft that may have received affected parts during maintenance. It also removes one serial number from a previous group listing and provides clearer instructions on compliance for different aircraft groups. The directive retains all previous requirements while addressing operator requests for clarification.
Why it matters
This directive is critical for aviation professionals because corrosion in crew oxygen pipes can lead to blocked or reduced oxygen supply during emergencies such as decompression or cockpit smoke/fire, posing serious safety risks. Operators, maintenance organizations, and compliance teams must ensure affected parts are identified and replaced promptly to maintain regulatory compliance and flight safety. Failure to comply could result in unsafe aircraft operation and regulatory penalties.
