Background On July 1, 2012, Dassault applied for a type certificate for its new Model Falcon 5X airplane. However, Dassault has decided not to release an airplane under the model designation Falcon 5X, instead choosing to change that model designation to Falcon 6X. In February of 2018, due to engine supplier issues, Dassault extended the type certificate application date for its Model Falcon 5X airplane under new Model Falcon 6X. This airplane is a twin-engine business jet with seating for 19 passengers, and has a maximum takeoff weight of 77,460 pounds. Type Certification Basis Under the provisions of 14 CFR 21.17, Dassault must show that the Model Falcon 6X airplane meets the applicable provisions of part 25, as amended by amendments 25–1 through 25–146. If the Administrator finds that the applicable airworthiness regulations (e.g., 14 CFR part 25) do not contain adequate or appropriate safety standards for the Dassault Model Falcon 6X airplane because of a novel or unusual design feature, special conditions are prescribed under the provisions of § 21.16. Special conditions are initially applicable to the model for which they are issued. Should the type certificate for that model be amended later to include any other model that incorporates the same novel or unusual design feature, these special conditions would also apply to the other model under § 21.101. In addition to the applicable airworthiness regulations and special conditions, the Dassault Model Falcon 6X airplane must comply with the fuelvent and exhaust-emission requirements of 14 CFR part 34, and the noisecertification requirements of 14 CFR part 36.

SUPPLEMENTARY INFORMATION: Background The European Union Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Emergency AD 2022–0018–E, dated January 28, 2022 (referred to after this as ‘‘the MCAI’’), to address an unsafe condition on certain MARS A.S. ATL– 88/90–1B (commercially known as ATL–15 SL) emergency parachutes. The MCAI states: During the yearly inspection of one of the affected emergency parachutes, it has been found that the length of the ripcord between the pins was too large and, in some cases, only one of 2 loops of the parachute could be opened when the manual ripcord was pulled. Subsequent inspection revealed that the dimensions of the static line extension were out of production tolerances. It is expected that the manufacturer will develop a modification to restore the airworthiness of affected emergency parachutes. This condition, if not corrected, could cause a malfunction of the emergency parachute. To address this unsafe condition EASA issued Emergency AD 2022–0017–E to require removal from service of the affected emergency parachutes. Since that [EASA] AD was issued, it was determined that the Applicability of that [EASA] AD was incorrect. For the reasons described above, this [EASA] AD retains the requirements of EASA Emergency AD 2022–0017–E, which is superseded, but with a different Applicability. This [EASA] AD is considered to be an interim measure and further [EASA] AD action may follow.

Background

    On July 1, 2012, Dassault applied for a type certificate for its 
new Model Falcon 5X airplane. However, Dassault has decided not to 
release an airplane under the model designation Falcon 5X, instead 
choosing to change that model designation to Falcon 6X.
    In February of 2018, due to engine supplier issues, Dassault 
extended the type certificate application date for its Model Falcon 5X 
airplane under new Model Falcon 6X. This airplane is a twin-engine 
business jet with seating for 19 passengers, and has a maximum takeoff 
weight of 77,460 pounds.

Type Certification Basis

    Under the provisions of 14 CFR 21.17, Dassault must show that the 
Model Falcon 6X airplane meets the applicable provisions of part 25, as 
amended by amendments 25-1 through 25-146.
    If the Administrator finds that the applicable airworthiness 
regulations (e.g., 14 CFR part 25) do not contain adequate or 
appropriate safety standards for the Dassault Model Falcon 6X airplane 
because of a novel or unusual design feature, special conditions are 
prescribed under the provisions of Sec.  21.16.
    Special conditions are initially applicable to the model for which 
they are issued. Should the type certificate for that model be amended 
later to include any other model that incorporates the same novel or 
unusual design feature, these special conditions would also apply to 
the other model under Sec.  21.101.
    In addition to the applicable airworthiness regulations and special 
conditions, the Dassault Model Falcon 6X airplane must comply with the 
fuel-vent and exhaust-emission requirements of 14 CFR part 34, and the 
noise-certification requirements of 14 CFR part 36.
    The FAA issues special conditions, as defined in 14 CFR 11.19, in 
accordance with Sec.  11.38, and they become part of the type 
certification basis under Sec.  21.17(a)(2).

Novel or Unusual Design Features

    The Dassault Model Falcon 6X airplane will incorporate the 
following novel or unusual design feature:
    Side-stick controllers for pitch and roll control.

Discussion

    Current part 25 airworthiness regulations account for conventional 
wheel-and-column airplane controls. Regulatory requirements pertaining 
to conventional wheel-and-column controls, such as pilot strength and 
controllability, are not directly applicable to side-stick controls. In 
addition, pilot-control authority may be uncertain because the side 
sticks are not mechanically interconnected to controlled surfaces, as 
are conventional wheel and column controls.
    Current FAA regulations do not specifically address the use of 
side-stick controllers for pitch and roll control. The unique features 
of the side stick must therefore be demonstrated through flight and 
simulator tests to have suitable handling and control characteristics 
when considering the following:
    1. The handling-qualities tasks and requirements of the Dassault 
Falcon Model 6X airplane Special Conditions and other 14 CFR part 25 
requirements for stability, control, and maneuverability, including the 
effects of turbulence.
    2. General ergonomics: Armrest comfort and support, local freedom 
of movement, displacement angle suitability, and axis harmony.
    3. Inadvertent input in turbulence.
    4. Inadvertent pitch-roll crosstalk.
    These special conditions contain the additional safety standards 
that the Administrator considers necessary to establish a level of 
safety equivalent to that established by the existing airworthiness 
standards.

Applicability

    As discussed above, these special conditions are applicable to the 
Dassault Model Falcon 6X airplane. Should Dassault apply at a later 
date for a change to the type certificate to include another model 
incorporating the same novel or unusual design feature, these special 
conditions would apply to that model as well.

Conclusion

    This action affects only a certain novel or unusual design feature

    The authority citation for these special conditions is as follows:

    Authority: 49 U.S.C. 106(f), 106(g), 40113, 44701, 44702, 44704.

The Special Conditions

    Accordingly, pursuant to the authority delegated to me by the 
Administrator, the following special conditions are issued as part of 
the type certification basis for the Dassault Aviation Model Falcon 6X 
airplane.
    1. Pilot strength: In lieu of the control force limits shown in 
Sec.  25.143(d) for pitch and roll, and in lieu of specific pitch force 
requirements of Sec. Sec.  25.143(i)(2), 25.145(b), 25.173(c), 
25.175(b), and 25.175(d), it must be shown that the temporary and 
maximum prolonged force levels for the side stick controllers are 
suitable for all expected operating conditions and configurations, 
whether normal or non-normal.
    2. Pilot-control authority: The electronic side-stick-controller 
coupling design must provide for corrective and/or overriding control 
inputs by either pilot with no unsafe characteristics. Annunciation of 
the controller status must be provided, and must not be confusing to 
the flightcrew.
    3. Pilot control: It must be shown by flight tests that the use of 
side-stick controllers does not produce unsuitable pilot-in-the-loop 
control characteristics when considering precision path control/tasks 
and turbulence. In addition, pitch and roll control force and 
displacement sensitivity must be compatible, so that normal inputs on 
one control axis will not cause significant unintentional inputs on the
