Background The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA
Emergency AD 20210036E, dated January 25, 2021 EASA Emergency AD
20210036E also referred to as the Mandatory Continuing Airworthiness Information, or the MCAI, to correct an unsafe condition for all Dassault Aviation Model FALCON 7X airplanes.
This AD was prompted by a report of deviations concerning the assembly and overhaul of certain crew oxygen mask stowage boxes, including incorrect application of Loctite 222 thread-locker on the fitting sensor screws. The FAA is issuing this AD to address such deviations, which could lead to blocked oxygen supply flow to flight deck crew oxygen masks. In combination with inflight depressurization, flight deck smoke, or a smoke evacuation procedure, this lack of oxygen may lead to flightcrew hypoxia and loss of useful consciousness and consequent loss of control of the airplane. See the MCAI for additional background information.
Related Service Information Under 1
CFR Part 51

describes procedures for an inspection test of crew oxygen mask stowage boxes having part number CSD30005
XX X can represent any alphanumeric value for discrepancies an inability to clearly hear oxygen flowing out of the mask during a functional test or see that the yellow blinker on the stowage box does not illuminate, and replacement.
This material is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section.
FAAs Determination This product has been approved by the aviation authority of another country, and is approved for operation in the United States.
