AD 2022-17-10 Airworthiness Directives; Dassault Aviation Airplanes
Models named: FALCON 7X. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
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.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, European Union Aviation Safety Agency (EASA) AD 2021-0272, dated December 6, 2021 (EASA AD 2021-0272).
Unsafe condition
This AD was prompted by reports of defects on the piston hole associated with the O 2 saver function that may prevent efficient deactivation of the O 2 saver function and a determination that the airplane flight manual (AFM) amendment required by AD 2021-19-20 may not be sufficient to mitigate the risk of failed deactivation of the O 2 saver function. The FAA is issuing this AD to address defects that may prevent efficient deactivation of the O 2 saver function, which could result in an inadequate oxygen supply to the flightcrew in case of decompression of the airplane or smoke or fire in the flight deck.
Affected ADs
This AD replaces AD 2021-19-20, Amendment 39-21738 (86 FR 51604, September 16, 2021) (AD 2021-19-20).
