What to do

Operators of Falcon 7X aircraft in Group 1 must incorporate AFM change CP0188 within 10 flight cycles after 8 August 2022 and upgrade the MAIC software within 12 months of the AD's effective date. Prior to software upgrade, aircraft without mod M1638 must be modified per Dassault SB 7X-436 rev. 01. After modification, AFM CP0189 must be implemented before the next flight, and flight crews informed accordingly. Compliance with these actions ensures continued airworthiness.

Summary

EASA Proposed Airworthiness Directive 26-076 addresses Dassault Aviation Falcon 7X aeroplanes, serial numbers 2 through 400 inclusive, that have not incorporated modification M1000. This directive focuses on maintenance and avionics interface computer software modifications and amendments to the Airplane Flight Manual to improve flight control safety. It supersedes a previous emergency AD and mandates software upgrades and procedural updates to ensure proper crew awareness of inboard slat configurations during flight.

What changed

EASA PAD 26-076 supersedes Emergency AD 2022-0161-E and introduces a required upgrade to the Maintenance and Avionics Interface Computer software on Falcon 7X aircraft. It also mandates amendments to the Airplane Flight Manual with updated change projects CP0188 and CP0189 to enhance procedures related to slat failure events. Additionally, it requires certain pre-modification actions for aircraft not having embodied Dassault mod M1638.

Why it matters

This 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. Aviation professionals must comply to maintain aircraft airworthiness and ensure flight crew are properly alerted to slat failures. Operators and maintenance organizations must update software and manuals to prevent unsafe conditions and comply with regulatory requirements.
