EASA AD 2025-0037: Superseded by EASA AD 2025-0118

What to do

Operators must implement the procedures described in Airbus OEB 63 issue 1.0 within 7 days of the directive's effective date, inform all flight crews, and operate the aircraft accordingly. Amending the Aircraft Flight Manual with the OEB content or an equivalent temporary revision is an acceptable compliance method. Stakeholders may submit comments on the directive until 12 March 2025.

Summary

EASA Airworthiness Directive 2025-0037 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting Airbus A319, A320, and A321 aeroplanes with specific Airbus modifications embodied. The directive addresses issues related to loss of synchronization between radio management panels, which can result in loss of radio communications, transponder functionality, and standby navigation. It requires amendments to the Aircraft Flight Manual to include procedures to manage these failures.

What changed

This directive introduces a requirement to amend the Aircraft Flight Manual by incorporating procedures from Airbus Operations Engineering Bulletin 63 issue 1.0 to regain communication and transponder functionality in case of radio management panel synchronization loss. It is an interim action with potential for further directives to follow. The directive also postpones public consultation until after publication, allowing comments within a specified period.

Why it matters

This directive is critical for aviation professionals as it addresses a potential unsafe condition that could lead to total loss of radio communications and navigation aids, impacting flight safety. Operators and maintenance teams must ensure compliance to maintain aircraft airworthiness and operational safety. The amendment to the flight manual provides essential procedures to manage communication failures effectively during flight.
