EASA AD 2020-0014
Enhanced Avionics System — Software Check
Summary
EASA Airworthiness Directive 2020-0014 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting Dassault Aviation Falcon 7X aeroplanes that have embodied modification M1000 (Falcon 8X) and either modification M1745 or Service Bulletin 7X-430. The directive mandates a one-time check of the avionics system software version and CD-ROM on board to ensure the correct EASy III software version is installed. It addresses potential safety risks from incorrect software loading that could affect aircraft guidance and operational safety.
What Changed
This new airworthiness directive introduces mandatory checks of the EASy 'Top-Level System' operational software version and the CD-ROM used for software uploads on affected Falcon 7X aircraft. It requires corrective actions if incorrect software or CD-ROMs are found, including amending the Aircraft Flight Manual to limit VNAV use until the correct software is installed. It also prohibits uploading or installing any software or CD-ROMs that are not the approved versions from the effective date.
Why It Matters
This directive is critical for aviation professionals because incorrect avionics software can lead to misleading flight information and erroneous aircraft behavior, potentially compromising safety margins. Operators and maintenance organizations must ensure compliance to avoid operational restrictions and maintain continued airworthiness. The directive helps prevent unsafe conditions by enforcing software version control and proper documentation updates.
What To Do
Operators of affected Falcon 7X aircraft must perform a software version and CD-ROM check within 30 days of 2020-02-12. If incorrect software is found, they must limit VNAV use until the correct software is uploaded within two months of the effective date. Incorrect CD-ROMs must be removed and replaced within two months. From the effective date, only the approved software versions and CD-ROMs may be installed or uploaded.
