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 Aviation
applied for a type certificate for their
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 their
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 title 14, Code
of Federal Regulations (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
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.
PO 00000
Frm 00009
Fmt 4700
Sfmt 4700

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
electronic flight-control system (EFCS)
and no direct coupling from the flight
deck controller to the control surface.
Discussion
As a result of the EFCS and lack of
direct coupling from the flight deck
controller to the control surface, the
pilot is not aware of the actual control
surface position. Some unusual flight
conditions, arising from atmospheric
conditions and/or airplane or engine
failures, may result in full or nearly full
surface deflection. Unless the flightcrew
is made aware of excessive deflection or
impending control surface limiting,
piloted or auto-flight system control of
the airplane might be inadvertently
continued in such a manner to cause
loss of control or other unsafe stability
or performance characteristics. The
airworthiness standards do not contain
adequate or appropriate safety standards
for the conditions that result from the
EFCS and lack of direct coupling from
the flight deck controller to the control
surface.
To establish a level of safety
equivalent to that established in the
regulations, these special conditions are
established. These special conditions
require that the flightcrew receive
suitable flight-control position
annunciation when a condition exists in
which nearly full surface authority (not
crew commanded) is being utilized.
Suitability of such an alerting must take
into account that some pilot-demanded
maneuvers (e.g., rapid roll) are
necessarily associated with intended
full performance, which may saturate
the surface. Therefore, simple alerting
systems, which would function in either
intended or unexpected control-limiting
situations, must be properly balanced
between necessary crew awareness and
unwanted nuisance factors. A
monitoring system that might compare
airplane motion, surface deflection, and
pilot demand could be helpful in
reducing nuisance alerting.
Additionally, these special conditions
address flight control system mode
annunciation. Suitable mode
annunciation must be provided to the
flightcrew for events that significantly
change the operating mode of the
system but do not merit the classic
‘‘failure warning.’’

Federal Register / Vol. 88, No. 97 / Friday, May 19, 2023 / Rules and Regulations
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 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.
This action affects only a certain
novel or unusual design feature on one
model of airplane. It is not a rule of
general applicability.

Authority Citation
The authority citation for these
special conditions is as follows:
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 as part of the type
certification basis for the Dassault
Aviation Model Falcon 6X airplane.
In addition to compliance with
§§ 25.143, 25.671, 25.672, and 25.1322,
the following special conditions apply:
1. The system design must ensure that
the flightcrew is made suitably aware
whenever the primary control means
nears the limit of control authority.
Note: the term ‘‘suitably aware’’ indicates
annunciations provided to the flightcrew are
appropriately balanced between nuisance
and that necessary for crew awareness.
2. If the flight-control system has
multiple modes of operation, the system
must alert the flight crew when the
airplane enters any mode that
significantly changes or degrades the
normal handling or operational
characteristics of the airplane.

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 all CFM LEAP–1A model
turbofan engines. The NPRM published
in the Federal Register on March 24,
2023 (88 FR 17753). The NPRM was
prompted by notification from the
manufacturer that iron inclusion was
detected in three non-LEAP–1A HPT
rotor disks. Further investigation by the
manufacturer determined that the iron
inclusion is attributed to deficiencies in
the manufacturing process. The
investigation by the manufacturer also
determined that certain CFM LEAP–1A
HPT stage 1 disks, forward outer seals,
and compressor rotor stages 6–10 spools
manufactured using the same process
may have reduced material properties
and a lower fatigue life capability due
to iron inclusion, which may cause
premature fracture and subsequent
uncontained failure of certain HPT stage
1 disks, forward outer seals, and
compressor rotor stages 6–10 spools. In
the NPRM, the FAA proposed to require
replacement of certain HPT stage 1
disks, forward outer seals, and
compressor rotor stages 6–10 spools.
The FAA also proposed to prohibit
installation of an HPT stage 1 disk,
forward outer seal, or compressor rotor
stages 6–10 spool that has a part number
and serial number identified in the
service information onto any engine.
The FAA is issuing this AD to address
the unsafe condition on these products.
Discussion of Final Airworthiness
Directive
Comments
The FAA received one comment, from
Air Line Pilots Association,
International (ALPA). ALPA supported
the NPRM without change.

Therefore, the FAA finds, pursuant to Sec. 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 Aviation applied for a type certificate
for their 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 their 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 title 14, Code of Federal Regulations (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 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: An electronic flight-control
system (EFCS) and no direct coupling from the flight deck controller to
the control surface.
Discussion
As a result of the EFCS and lack of direct coupling from the flight
deck controller to the control surface, the pilot is not aware of the
actual control surface position. Some unusual flight conditions,
arising from atmospheric conditions and/or airplane or engine failures,
may result in full or nearly full surface deflection. Unless the
flightcrew is made aware of excessive deflection or impending control
surface limiting, piloted or auto-flight system control of the airplane
might be inadvertently continued in such a manner to cause loss of
control or other unsafe stability or performance characteristics. The
airworthiness standards do not contain adequate or appropriate safety
standards for the conditions that result from the EFCS and lack of
direct coupling from the flight deck controller to the control surface.
To establish a level of safety equivalent to that established in
the regulations, these special conditions are established. These
special conditions require that the flightcrew receive suitable flight-
control position annunciation when a condition exists in which nearly
full surface authority (not crew commanded) is being utilized.
Suitability of such an alerting must take into account that some pilot-
demanded maneuvers (e.g., rapid roll) are necessarily associated with
intended full performance, which may saturate the surface. Therefore,
simple alerting systems, which would function in either intended or
unexpected control-limiting situations, must be properly balanced
between necessary crew awareness and unwanted nuisance factors. A
monitoring system that might compare airplane motion, surface
deflection, and pilot demand could be helpful in reducing nuisance
alerting.
Additionally, these special conditions address flight control
system mode annunciation. Suitable mode annunciation must be provided
to the flightcrew for events that significantly change the operating
mode of the system but do not merit the classic ``failure warning.''
[[Page 32092]]
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
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.

Authority Citation
The authority citation for these special conditions is as follows:
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 as part of
the type certification basis for the Dassault Aviation Model Falcon 6X
airplane.
In addition to compliance with Sec. Sec. 25.143, 25.671, 25.672,
and 25.1322, the following special conditions apply:
1. The system design must ensure that the flightcrew is made
suitably aware whenever the primary control means nears the limit of
control authority.
Note: the term ``suitably aware'' indicates annunciations
provided to the flightcrew are appropriately balanced between
nuisance and that necessary for crew awareness.
2. If the flight-control system has multiple modes of operation,
the system must alert the flight crew when the airplane enters any mode
that significantly changes or degrades the normal handling or
operational characteristics of the airplane.
