What to do
Operators of Falcon 7X aeroplanes must incorporate AFM Change Project CP0188 within 10 flight cycles after 8 August 2022 if not already done, and upgrade the MAIC software within 12 months after 6 August 2026. Prior to software upgrade, aircraft without mod M1638 must comply with SB 7X-436 Rev 1. After modification, AFM must be amended with CP0189 before the next flight, and flight crews must be informed of the changes. Compliance with these actions is mandatory to continue operation.
Summary
EASA Airworthiness Directive 2026-0145 is issued for Dassault Aviation Falcon 7X aeroplanes, serial numbers 2 through 400 inclusive, addressing flight controls maintenance and avionics interface computer software modifications. This directive mandates updates to the Maintenance and Avionics Interface Computers (MAIC) software and amendments to the Airplane Flight Manual (AFM) to enhance crew awareness of inboard slat configuration during failures. It supersedes a previous emergency AD related to the same issue.
What changed
This AD supersedes EASA Emergency AD 2022-0161-E and requires upgrading the MAIC software via Dassault Service Bulletin 7X-650 Rev 1 and amending the AFM with Change Projects CP0188 and CP0189. It introduces a new modification (mod M2138) that restores crew alerting for inboard slat failures and updates operational procedures accordingly. Additionally, it mandates a prerequisite modification per SB 7X-436 Rev 1 for certain aircraft before software upgrade.
Why it matters
The directive addresses a critical safety issue where failed extension of inboard slats during landing was not indicated to flight crews, potentially reducing lift and control during approach and landing. Compliance ensures that operators maintain aircraft airworthiness and flight safety by restoring proper crew alerting and updated procedures. It also aligns maintenance and operational practices with the latest manufacturer and regulatory requirements, reducing risk of accidents related to slat failures.
