What to do
Operators of affected Airbus A319, A320, and A321 aircraft must modify the LPSOV electrical harness routing in accordance with the applicable Airbus service bulletin before exceeding 7 years since the aircraft's date of manufacture or within 12 months after 19 September 2022, whichever occurs later. If necessary, operators should contact Airbus for approved instructions and may request alternative methods of compliance from EASA if substantiated.
Summary
EASA Airworthiness Directive 2022-0185 is an airworthiness directive issued by EASA affecting Airbus A319, A320, and A321 aircraft equipped with International Aero Engines PW1100 series or CFM International LEAP-1A series engines. The directive addresses the electrical harness routing of the engine low pressure shut off valve (LPSOV) to enhance protection against uncontained engine rotor failure. It applies to all manufacturer serial numbers except those with Airbus modification 167036 embodied in production.
What changed
This new airworthiness directive requires modification of the LPSOV electrical harness routing on affected aircraft to improve protection against potential damage from uncontained engine rotor failure. Airbus developed modification 167036 and issued service bulletins A320-92-1144 and A320-92-1145 to provide instructions for the required in-service modification.
Why it matters
This directive is critical for aviation professionals because inadequate protection of the LPSOV electrical harness could lead to loss of engine fuel isolation capability in the event of an uncontained engine rotor failure, potentially resulting in an uncontrolled fire. Operators, maintenance organizations, and compliance teams must ensure timely compliance to maintain aircraft safety and regulatory conformity.
