14 CFR Part 25
[Docket No. FAA-2014-1077; Special Conditions No. 25-609-SC]
Special Conditions: Dassault Aviation Model Falcon 5X Airplane,
Design Roll Maneuver Condition
AGENCY: Federal Aviation Administration (FAA), DOT.
[[Page 7966]]
ACTION: Final special conditions; request for comments.
-----------------------------------------------------------------------
SUMMARY: These special conditions are issued for the Dassault Aviation
Model Falcon 5X airplane. This airplane will have novel or unusual
design features when compared to the state of technology envisioned in
the airworthiness standards for transport-category airplanes. This
design feature is electronic flight controls that affect maneuvering.
The applicable airworthiness regulations do not contain adequate or
appropriate safety standards for this design feature. 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.
DATES: This action is effective on Dassault Aviation on February 17,
2016. We must receive your comments by April 4, 2016.

FOR FURTHER INFORMATION CONTACT: Mark Freisthler, FAA, Airframe and
Cabin Safety Branch, ANM-115, Transport Airplane Directorate, Aircraft
Certification Service, 1601 Lind Avenue SW., Renton, Washington 98057-
3356; telephone 425-227-1119; facsimile 425-227-1320.
SUPPLEMENTARY INFORMATION: The FAA has determined that notice of, and
opportunity for prior public comment on, these special conditions is
impracticable because these procedures would significantly delay
issuance of the design approval and thus delivery of the affected
airplane.
In addition, the substance of these special conditions has been
subject to the public-comment process in several prior instances with
no substantive comments received. The FAA therefore finds that good
cause exists for making these special conditions effective upon
publication in the Federal Register.
Comments Invited
We invite 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.
We will consider all comments we receive by the closing date for
comments. We may change these special conditions based on the comments
we receive.
Background
On July 1, 2012, Dassault Aviation applied for a type certificate
for their new Model Falcon 5X airplane.
The Model Falcon 5X airplane is a transport-category airplane to be
operated in private/corporate transportation with a maximum of 19
passengers. The airplane incorporates a low, swept-wing design with
winglets; twin rear-fuselage-mounted engines; and the newest generation
of Dassault Aviation's EASy flightdeck.
The Model Falcon 5X will include electronic flight controls that
affect maneuvering.
Type Certification Basis
Under the provisions of 14 CFR 21.17, Dassault Aviation must show
that the Model Falcon 5X airplane meets the applicable provisions of
part 25, as amended by Amendments 25-1 through 25-136.
If the Administrator finds that the applicable airworthiness
regulations (i.e., 14 CFR part 25) do not contain adequate or
appropriate safety standards for the Model Falcon 5X 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 Model Falcon 5X 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 Model Falcon 5X airplane will incorporate the following novel
or unusual design feature:
This airplane is equipped with an electronic flight-control system
that provides control through pilot inputs to the flight computer,
thereby affecting maneuverability of the airplane as compared to
conventional control systems.
Discussion
Current part 25 airworthiness regulations account for control laws
for which aileron deflection is proportional to control-stick
deflection. They do not address nonlinearities or other effects on
aileron actuation that may be caused by electronic flight controls.
Because this type of system may affect flight loads, and therefore the
structural capability of the airplane, specific regulations are needed
to address these effects.
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
Model Falcon 5X airplane. Should Dassault Aviation apply at a later
date for a
[[Page 7967]]
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 certain novel or unusual design features
on one model of airplane. It is not a rule of general applicability.
The substance of these special conditions has been subjected to the
notice and comment period in several prior instances and has been
derived without substantive change from those previously issued. It is
unlikely that prior public comment would result in a significant change
from the substance contained herein. Therefore, because a delay would
significantly affect the certification of the airplane, which is
imminent, the FAA has determined that prior public notice and comment
are unnecessary and impracticable, and good cause exists for adopting
these special conditions upon publication in the Federal Register. The
FAA is requesting comments to allow interested persons to submit views
that may not have been submitted in response to the prior opportunities
for comment described above.

Authority: 49 U.S.C. 106(g), 40113, 44701, 44702, 44704.
The Special Conditions
0
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 Dassault Aviation Model Falcon 5X
airplanes.
In lieu of compliance to Sec. 25.349(a), the following conditions,
speeds, and cockpit roll-control motions (except as the motions may be
limited by pilot effort) must be considered in combination with an
airplane load factor of zero, and of two-thirds of the positive
maneuvering factor used in design. In determining the resulting
control-surface deflections, the torsional flexibility of the wing must
be considered in accordance with Sec. 25.301(b).
1. Conditions corresponding to steady rolling velocities must be
investigated. In addition, conditions corresponding to maximum angular
acceleration must be investigated for airplanes with engines or other
weight concentrations outboard of the fuselage. For the angular
acceleration conditions, zero rolling velocity may be assumed in the
absence of a rational time-history investigation of the maneuver.
2. At VA, sudden movement of the cockpit roll control up
to the limit is assumed. The position of the cockpit roll control must
be maintained until a steady roll rate is achieved, and then must be
returned suddenly to the neutral position.
3. At VC, the cockpit roll control must be moved
suddenly and maintained so as to achieve a roll rate not less than that
obtained in special condition 2, above.
4. At VD, the cockpit roll control must be moved
suddenly and maintained so as to achieve a roll rate not less than one-
third of that obtained in special condition 2, above.
Issued in Renton, Washington, on February 4, 2016.
