Airworthiness Directive · Amendment 39-21738 · Oxygen
Dassault Aviation Airplanes
Superseded. A later AD replaced this one: AD 2022-17-10. Comply with the one in force.
This AD applies to all Dassault Aviation Model FALCON 7X airplanes, certificated in any category.
Note 1 to paragraph (c): Model FALCON 7X airplanes with Dassault modification M1000 incorporated are commonly referred to as “Model FALCON 8X” as a marketing designation.
The FAA is adopting a new airworthiness directive (AD) for all Dassault Aviation Model FALCON 7X airplanes. This AD was prompted by a report of defects on the piston hole associated with the O<INF>2</INF> saver feature that may prevent efficient deactivation of the O<INF>2</INF> saver function. This AD requires amending the existing airplane flight manual (AFM) to incorporate a check and an operating limitation regarding the O<INF>2</INF> saver function, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD also limits the installation of affected parts under certain conditions. The FAA is issuing this AD to address the unsafe condition on these products.
Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, EASA AD 2021-0202R1, dated September 10, 2021 (EASA AD 2021-0202R1).
(1) Where EASA AD 2021-0202R1 refers to its effective date, this AD requires using the effective date of this AD.
(2) Paragraph (1) of EASA AD 2021-0202R1 specifies amending “the applicable AFM [airplane flight manual],” but this AD requires amending the applicable existing AFM and applicable corresponding operational procedures.
(3) Whereas paragraph (1) of EASA AD 2021-0202R1 requires operators to “inform all flight crews” of the AFM amendments, and thereafter to “operate the aeroplane accordingly,” this AD does not specifically require those actions as they are already required by FAA regulations.
(4) This AD does not mandate compliance with the “Remarks” section of EASA AD 2021-0202R1.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
