SUPPLEMENTARY INFORMATION: SUMMARY: jspears on DSK121TN23PROD with RULES1 Manufactured after January 1, 1994 VerDate Sep<11>2014 19:58 Mar 22, 2022 Jkt 256001 Background On July 1, 2012, Dassault Aviation applied for a type certificate for their new Model Falcon 5X airplane. Special conditions were issued for that design on January 27, 2016 (81 FR 4579). 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 their Model Falcon 5X airplane under new Model Falcon 6X. This amendment to the original special conditions reflects the model-name change. This airplane is a twin-engine business jet with seating for 19 passengers and a maximum takeoff weight of 77,460 pounds. The Dassault Model Falcon 6X airplane design remains unchanged from the Model Falcon 5X in all material respects other than different engines. 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 (i.e., 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 noise- PO 00000 Frm 00017 Fmt 4700 Sfmt 4700 1.6 (6.0) 1.6 (6.0) 1.6 (6.0) 3.5 (13.2) ............................

The FAA issues special conditions, as defined in 14 CFR 11.19, in accordance with § 11.38, and they become part of the type certification basis under § 21.17(a)(2). Novel or Unusual Design Features The Dassault Model Falcon 6X 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 wheel or control stick. Discussion The Dassault Model Falcon 6X airplane is equipped with a side stick instead of a conventional wheel or control stick. The requirement of § 25.397(c), which defines limit pilot forces and torques, applies to conventional wheel or control stick and is therefore not adequate for this new side-stick design with electronic flight controls that affect maneuvering. 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. Discussion of Comments The FAA issued Final Special Conditions, Request for Comment Special Conditions No. 25–607–SC for the Dassault Model Falcon 5X airplane, which was published in the Federal Register on January 27, 2016 (81 FR 4579). No comments were received, and the special conditions are adopted as proposed, with amendments. Applicability As discussed above, these special conditions are applicable to the Dassault Model Falcon 6X airplane.

Conclusion This action affects only certain novel or unusual design features on one model of airplane. It is not a rule of general applicability. 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, in lieu of the aileron-control and elevator-control forces specified in § 25.397(c), as part of the type-certification basis for the Dassault Model Falcon 6X airplane. For airplanes equipped with sidestick 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 controlassembly handle and its control stops: Pitch Roll Nose up, 200 lbs force ... Nose down, 200 lbs force. Nose left, 100 lbs force. Nose right, 100 lbs force. 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: Roll Nose left, 50 lbs force. Nose right, 50 lbs force. jspears on DSK121TN23PROD with RULES1 Issued in Kansas City, Missouri, on March 18, 2022. Patrick R.

SUPPLEMENTARY INFORMATION: Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to Bell Textron Inc., Model 412, 412EP, and 412CF helicopters. The NPRM published in the Federal Register on August 27, 2021 (86 FR 48078). The NPRM was prompted by the results of an evaluation of BLR Aerospace Strake and FastFin (Strake and FF) system part number (P/N) 412– 705–040–101. The NPRM stated that during the evaluation, additional flight loads were recorded that impact the collective lever fatigue life. Accordingly, the NPRM proposed to require adding a permanent life penalty for affected collective levers and prohibit installing those collective levers unless the permanent life penalty has been added. This condition, if not addressed, could result in fatigue damage and cracking, failure of the collective lever, and subsequent loss of control of the helicopter. The FAA is issuing this AD to address the unsafe condition on these products. Discussion of Final Airworthiness Directive Comments The FAA received comments from one commenter; Bell Textron, Inc. The following presents the comments received on the NPRM and the FAA’s response to each comment. Request for a Change to Nomenclature Bell Textron, Inc., requested the FAA revise the penalty nomenclature from ‘‘life penalty’’ to ‘‘flight hour penalty’’ throughout the AD action. Bell Textron, Inc., stated that the penalty is only applied to hours TIS and that the life remains unchanged. The FAA partially agrees. The FAA agrees to changing the nomenclature; however, the nomenclature typically used in rotorcraft FAA AD actions for domestic products is ‘‘hours TIS’’ (or ‘‘total hours TIS’’) instead of flight hours (or total flight hours). The FAA has revised that nomenclature accordingly in this final rule. Request for a Change to the Description of What Prompted This AD Bell Textron, Inc., requested the FAA clarify the description of what prompted this AD; specifically that during the evaluation, the additional flight loads E:\FR\FM\23MRR1.SGM 23MRR1

Pilot Forces--Side-Stick Controller

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final special conditions; amendment.

-----------------------------------------------------------------------

SUMMARY: 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 airplane is equipped with an electronic flight-control 
system that includes pilot controls through a side stick instead of 
through a conventional wheel or 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 on March 23, 2022.

SUPPLEMENTARY INFORMATION:

Background

    On July 1, 2012, Dassault Aviation applied for a type certificate 
for their new Model Falcon 5X airplane. Special conditions were issued 
for that design on January 27, 2016 (81 FR 4579). 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 their Model Falcon 
5X airplane under new Model Falcon 6X. This amendment to the original 
special conditions reflects the model-name change. This airplane is a 
twin-engine business jet with seating for 19 passengers and a maximum 
takeoff weight of 77,460 pounds. The Dassault Model Falcon 6X airplane 
design remains unchanged from the Model Falcon 5X in all material 
respects other than different engines.

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 (i.e., 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:
    This airplane is equipped with an electronic flight-control system 
that includes pilot controls through a side stick instead of through a 
conventional wheel or control stick.

Discussion

    The Dassault Model Falcon 6X airplane is equipped with a side stick 
instead of a conventional wheel or control stick. The requirement of 
Sec.  25.397(c), which defines limit pilot forces and torques, applies 
to conventional wheel or control stick and is therefore not adequate 
for this new side-stick design with electronic flight controls that 
affect maneuvering.
    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.

Discussion of Comments

    The FAA issued Final Special Conditions, Request for Comment 
Special Conditions No. 25-607-SC for the Dassault Model Falcon 5X 
airplane, which was published in the Federal Register on January 27, 
2016 (81 FR 4579). No comments were received, and the special 
conditions are adopted as proposed, with amendments.

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

[[Page 16388]]

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.
