EASA AD 2020-0181
Airplane Flight Manual — Sections Emergency and Abnormal Procedures — Amendment
Summary
EASA Airworthiness Directive 2020-0181 is an amendment to the Airplane Flight Manual sections covering Emergency and Abnormal Procedures for Dassault Aviation Falcon 7X, 900EX, and 2000EX aeroplanes. It addresses issues related to Primary Display Unit data flickering and potential total loss of all display units on aircraft equipped with EASy software. The directive applies to all serial numbers of Falcon 7X including Falcon 8X in production, Falcon 900EX with EASy configuration, and Falcon 2000EX with EASy configuration.
What Changed
This directive requires amending the applicable Airplane Flight Manual to incorporate new emergency and abnormal procedures designed to manage flickering or loss of Primary Display Units. Dassault issued specific AFM Change Projects that must be incorporated within 30 days of the effective date. The amendment introduces procedures to handle unrecoverable display failures and reduce crew workload during such events.
Why It Matters
This amendment is critical for aviation professionals as it ensures flight crews have updated procedures to safely manage display unit failures, which could otherwise lead to excessive workload and compromised communication and navigation. Operators and maintenance teams must ensure compliance to maintain aircraft airworthiness and operational safety. The directive also helps prevent potential in-flight hazards related to avionics display malfunctions.
What To Do
Operators of affected Dassault Falcon 7X, 900EX, and 2000EX aeroplanes must amend their Airplane Flight Manuals within 30 days of 27 August 2020 to include the specified AFM Change Projects. Flight crews must be informed of these changes and operate the aircraft according to the updated emergency and abnormal procedures. Incorporating later AFM revisions that include these changes is also acceptable for compliance.
