EASA AD 2022-0145
SUPERSEDED BY EASA AD 2023-0003
Summary
EASA Airworthiness Directive 2022-0145 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting Dassault Aviation Falcon 7X aeroplanes, including those modified to Falcon 8X standard except those with mod M2091. It addresses a potential unsafe condition in the Falcon 7X EASy avionics architecture that could lead to misleading data on display units and increased pilot workload.
What Changed
This directive supersedes EASA AD 2021-0197 and retains its requirements while introducing a new modification (mod M2091) for certain serial numbers to upgrade the avionics to the EASy III – 4th CERT standard. It mandates amendments to the Aircraft Flight Manual, implementation of updated Master Minimum Equipment List and Operational Suitability Manual for all affected aircraft, and requires modification of Group 2 aeroplanes within 12 months.
Why It Matters
This AD is critical for maintaining the safety and operational integrity of Falcon 7X aircraft by addressing a known weakness in the avionics system that could compromise flight safety. Operators, maintenance organizations, and compliance teams must ensure timely compliance to avoid increased pilot workload and potential loss of aircraft control. It also ensures that flight crews are properly informed and trained on updated procedures.
What To Do
Operators must amend the Aircraft Flight Manual, implement the updated MMEL and Operational Suitability Manual within two months after 6 September 2021. For Group 2 aeroplanes, the required modification must be completed within 12 months after 26 July 2022, followed by further AFM amendments and crew notification. Compliance with these actions is mandatory to continue operating the affected aircraft.
