Abstract
These special conditions are issued for the Dassault Aviation (Dassault) Model Falcon 6X airplane. This airplane will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. This design feature is an overspeed protection system in the normal mode, designed to prevent the pilot from inadvertently or intentionally exceeding certain airplane speeds. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. This special conditions document contains the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.

AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final special conditions; request for comments.
-----------------------------------------------------------------------
SUMMARY: These special conditions are issued for the Dassault Aviation

public disclosure. If your comments responsive to these special
conditions contain commercial or financial information that is
customarily treated as private, that you actually treat as private, and
that is relevant or responsive to these special conditions, it is
important that you clearly designate the submitted comments as CBI.
Please mark each page of your submission containing CBI as ``PROPIN.''
The FAA will treat such marked submissions as confidential under the
FOIA, and the indicated comments will not be placed in the public
docket of these special conditions. Send submissions containing CBI to
the Information Contact below. Comments the FAA receives, which are not
specifically designated as CBI, will be placed in the public docket for
this rulemaking.
Docket: Background documents or comments received may be read at
<a href="https://www.regulations.gov/">https://www.regulations.gov/</a> at any time. Follow the online
instructions for accessing the docket or go to Docket Operations in

SUPPLEMENTARY INFORMATION: The substance of these special conditions
has been published in the Federal Register for public comment in
several prior instances with no substantive comments received.
Therefore, the FAA finds, pursuant to Sec. 11.38(b), that new comments
are unlikely, and notice and comment prior to this publication are
unnecessary.
Comments Invited
The FAA invites interested people to take part in this rulemaking
by sending written comments, data, or views. The most helpful comments
reference a specific portion of the special conditions, explain the
reason for any recommended change, and include supporting data.
The FAA will consider all comments received by the closing date for
comments. The FAA may change these special conditions based on the
comments received.
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
[[Page 16626]]
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:
An overspeed protection system in the normal mode, designed to
prevent the pilot from inadvertently or intentionally exceeding certain
airplane speeds.
Discussion
Current part 25 sections do not relate to a high-speed limiter that
might preclude or modify flying qualities assessments in the overspeed
region. This high-speed limiter incorporates an overspeed protection
system in the normal mode that prevents the pilot from inadvertently or
intentionally exceeding a speed approximately equivalent to
V<INF>FC</INF> (maximum speed for stability characteristics) or
attaining V<INF>DF</INF> (demonstrated flight diving speed).
These special conditions establish requirements to ensure operation
of the high-speed limiter that might preclude or modify flying
qualities assessments in the overspeed region.
This special conditions document contains 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
on one model of airplane. It is not a rule of general applicability.
