What to do
Operators must amend the applicable aircraft flight manual to include the specified changes, implement the updated master minimum equipment list instructions, and apply the operational suitability manual updates for flight crews. These actions must be completed within two months of the directive's effective date, and all flight crews must be informed and trained accordingly. Ongoing compliance with these updates is mandatory for continued aircraft operation.
Summary
EASA Airworthiness Directive 2021-0197 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting all Dassault Aviation Falcon 7X aeroplanes, including those modified to Falcon 8X standard. The directive addresses a potential safety issue related to the EASy avionics architecture that could lead to misleading data on display units. It mandates amendments to the aircraft flight manual, master minimum equipment list, and operational suitability manual to mitigate this risk.
What changed
This directive requires the incorporation of specific changes into the Falcon 7X flight manual, implementation of updates to the master minimum equipment list, and operational suitability manual for flight crews. These changes address a weak point in the avionics system that could cause misleading display data due to a theoretical input/output card failure. The directive is an interim action and may be followed by further directives.
Why it matters
This directive is critical for maintaining the safety and operational integrity of Falcon 7X aircraft by preventing potential misleading avionics data that could increase pilot workload and reduce aircraft control. Compliance ensures that operators and maintenance teams update documentation and procedures to reflect the latest safety information. It helps reduce the risk of incidents caused by avionics failures and supports regulatory compliance.
