Airworthiness Directive 2022-17-10
one-timeAirworthiness Directives; Dassault Aviation Airplanes
What this AD requires
The FAA is superseding Airworthiness Directive (AD) 2021-19- 20, which applied to all Dassault Aviation Model FALCON 7X airplanes. AD 2021-19-20 required amending the existing airplane flight manual (AFM) to incorporate a check and an operating limitation regarding the O<INF>2</INF> saver function. This AD was prompted by reports of defects that may prevent efficient deactivation of the O<INF>2</INF> saver function of crew oxygen masks and a determination that the AFM amendment required by AD 2021-19-20 may not be sufficient to mitigate the risk. This AD retains the requirements of AD 2021-19-20 and also requires physical deactivation of 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.
Which aircraft AD 2022-17-10 applies to
Model FALCON 7X airplanes with Dassault modification M1000 incorporated are commonly marketed as 'FALCON 8X' but are the same certificated model for this AD.
Whether AD 2022-17-10 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
