14 CFR Part 25 

[Docket No. FAA–2020–1040; Special 

Conditions No. 25–800–SC] 

Special Conditions: Dassault Aviation 

Model Falcon 6X Airplane; Flight 

Envelope Protection, High-Speed 

Limiting 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final special conditions; request 

for comments. 

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 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. 

DATES: This action is effective on 

Dassault on March 24, 2022. Send 

comments on or before May 9, 2022. 

ADDRESSES: Send comments identified

Confidential Business Information: 

Confidential Business Information (CBI) 

is commercial or financial information 

that is both customarily and actually 

treated as private by its owner. Under 

the Freedom of Information Act (FOIA) 

(5 U.S.C. 552), CBI is exempt from 

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 

https://www.regulations.gov/ at any 

time. Follow the online instructions for 

accessing the docket or go to Docket 

Operations in Room W12–140 of the

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 § 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 


khammond on DSKJM1Z7X2PROD with RULES
16626 Federal Register / Vol. 87, No. 57 / Thursday, March 24, 2022 / Rules and Regulations 

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: 

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 VFC (maximum speed for 

stability characteristics) or attaining VDF

(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.
