SUPPLEMENTARY INFORMATION:

Discussion of Final Airworthiness Directive
Background EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 20200284, dated December 18, 2020 EASA AD
20200284 also referred to as the MCAI, to correct an unsafe condition for Dassault Aviation Model FALCON
7X, FALCON 900EX, and FALCON
2000EX airplanes.
The FAA issued a notice of proposed rulemaking NPRM to amend 14 CFR
part 39 by adding an AD that would apply to Dassault Aviation Model FALCON 7X, FALCON 900EX, and FALCON 2000EX airplanes. The NPRM
published in the Federal Register on July 15, 2021 86 FR 37255. The NPRM
was prompted by a report of a manufacturing issue involving misalignment of a cabin seat pin and plate that can prevent the recline locking mechanism from properly engaging when the seat is in taxi, takeoff, or landing position. The NPRM
proposed to require an inspection of certain cabin seats for discrepancies and corrective action, as specified in EASA
AD 20200284.
The FAA is issuing this AD to address cabin seats having improper or no engagement of the recline locking mechanism during taxi, take-off, or landing, which could result in reduced seat performance under crash loads and possible injury to seat occupants. See the MCAI for additional background information.

The FAA received no comments on the NPRM or on the determination of the cost to the public.

Comments
Conclusion The FAA reviewed the relevant data and determined that air safety requires adopting this AD as proposed. Except for minor editorial changes, this AD is adopted as proposed in the NPRM.
None of the changes will increase the economic burden on any operator.
Accordingly, the FAA is issuing this AD
to address the unsafe condition on these products.
Related Service Information Under 1
CFR Part 51
EASA AD 20200284 specifies procedures for an inspection of certain cabin seats for discrepancies a gap between the seat pin and plate, and corrective action adjustment, deactivation, or repair, as applicable.
EASA AD 20200284 also prohibits installation of certain cabin seats. 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.
