14 CFR Part 25 

[Docket No. FAA–2014–1076; Special 

Conditions No. 25–607A–SC] 

Special Conditions: Dassault Aviation 

Model Falcon 6X, Limit 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 

§ 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. 

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. 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 


jspears on DSK121TN23PROD with RULES1
16388 Federal Register / Vol. 87, No. 56 / Wednesday, March 23, 2022 / Rules and Regulations 

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. 

List of Subjects in 14 CFR Part 25

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for Bell 

Textron Inc., Model 412, 412EP, and 

412CF helicopters. This AD was 

prompted by evaluation results showing 

flight loads that impact the collective 

lever fatigue life. This AD requires 

adding a permanent hours time-inservice (TIS) penalty for certain 

collective levers and prohibits installing 

those collective levers unless the 

permanent hours TIS penalty has been 

added. The FAA is issuing this AD to 

address the unsafe condition on these 

products. 

DATES: This AD is effective April 27, 

2022.

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
