14 CFR Part 25

[Docket No. FAA-2014-1076; Special Conditions No. 25-607-SC]


Special Conditions: Dassault Aviation Model Falcon 5X, Limit 
Pilot Forces

AGENCY: Federal Aviation Administration (FAA), DOT.

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 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 electronic flight-control system with pilot 
controls through a side stick instead of a conventional control stick. 
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 January 27, 
2016. We must receive your comments by March 14, 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 applied for a type certificate for their 
new Model Falcon 5X airplane. This airplane is a large transport-
category airplane to be operated in private/corporate transportation 
with a maximum of 19 passengers. The Falcon 5X is expected to have a 
range of 5,200 nm at Mach 0.80. The Model Falcon 5X airplane 
incorporates a low, swept wing with winglets, and twin rear-fuselage-
mounted Snecma Silvercrest turbofan engines. The fuselage is about 23 m 
long with a 26 m wingspan. The maximum altitude is 51,000 ft and 
maximum take-off weight is 30,225 kg. The Model Falcon 5X airplane also 
features the newest generation of Dassault Aviation's EASy flight deck.
    The current limit pilot forces requirement in Title 14, Code of 
Federal Regulations (14 CFR) part 25 is inadequate for addressing an 
airplane

[[Page 4580]]

with 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 includes pilot controls through a side stick instead of through a 
conventional control stick.

Discussion

    The Dassault Falcon 5X airplane is equipped with a side stick 
instead of a conventional control stick. The requirement of Sec.  
25.397(c), which defines limit pilot forces and torques, applies to 
conventional wheel or stick control and is therefore not adequate for 
this new side-stick design.
    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 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.

List of Subjects in 14 CFR Part 25

    Aircraft, Aviation safety, Reporting and recordkeeping 
requirements.

    The authority citation for these special conditions is as follows:

    Authority: 49 U.S.C. 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, in lieu of 
Sec.  25.397(c), as part of the type-certification basis for the 
Dassault Aviation Model Falcon 5X airplane.
    For Model Falcon 5X airplanes equipped with side-stick controls 
designed for forces to be applied by one wrist and not arms, the limit 
pilot forces are as follows.
    1. For all components between and including the side-stick control-
assembly handle and its control stops:

------------------------------------------------------------------------
                   Pitch                                Roll
------------------------------------------------------------------------
Nose up, 200 lbf..........................  Nose left, 100 lbf.
Nose down, 200 lbf........................  Nose right, 100 lbf.
------------------------------------------------------------------------

    2. For all other components of the side-stick control assembly, but 
excluding the internal components of the electrical sensor assemblies, 
to avoid damage to the control system as the result of an in-flight 
jam:

------------------------------------------------------------------------
                   Pitch                                Roll
------------------------------------------------------------------------
Nose up, 125 lbf..........................  Nose left, 50 lbf.
Nose down, 125 lbf........................  Nose right, 50 lbf.
