EASA AD 2025-0042: Aeroplane Flight Manual — Amendment

What to do

Operators of affected Falcon 2000EX aeroplanes must implement the AFM Change Project CP0176-PUB within one month after the effective date of 5 March 2025. Flight crews must be informed of the changes and operate the aircraft according to the updated AFM procedures. Compliance can be achieved by incorporating the AFM-CP or an equivalent AFM revision containing the same content.

Summary

EASA Airworthiness Directive 2025-0042 is an amendment concerning Dassault Aviation Falcon 2000EX aeroplanes, including variants such as Falcon 2000EX Easy, Falcon 2000 LX, Falcon 2000LXS, Falcon 2000S, and Falcon 2000DX with modification M1691 embodied. The directive addresses a safety issue related to simultaneous failure of main DC buses powered by generators during flap extension on approach. It mandates updates to the Aeroplane Flight Manual to provide flight crews with procedures to manage this abnormal electrical condition.

What changed

This directive requires the incorporation of Dassault's Aeroplane Flight Manual Change Project CP0176-PUB into the Falcon 2000EX AFM. The amendment introduces specific instructions for flight crews to handle the failure of both main DC buses and associated crew alerting system messages. It is a new regulation that mandates AFM updates to mitigate the identified unsafe condition.

Why it matters

This amendment is critical for aviation professionals as it addresses a potential electrical failure that can increase pilot workload during critical flight phases, such as approach. Operators and maintenance teams must ensure compliance to maintain aircraft airworthiness and safety. Failure to implement the AFM changes could result in inadequate crew response to electrical failures, potentially compromising flight safety.
