investigative interest on the part of DHS
as well as the recipient agency and
present an impediment to law
enforcement efforts and/or efforts to
preserve national security. This Final
Rule replaces a previous Final Rule that
was broader and permitted to DHS to
exempt this system from more
subsections of the Privacy Act’s
requirements.
The commenter also noted that when
an investigation is complete or has been
made public, the information should no
longer be exempt from the Privacy Act;
individuals have a right to know about
disclosures of their personal
information held by the agency. DHS
concurs in part with the comment and
has adjusted the Final Rule and SORN
accordingly. When an investigation is
complete, the agency will make a caseby-case determination whether
providing an accounting of disclosures
would undermine the investigative
process and present an impediment to
law enforcement efforts and/or efforts to
preserve national security. There may be
circumstances in which information
will continue to be exempted if the fact
that an investigation occurred remains
sensitive after completion. Nonetheless,
excluding accounting of disclosures,
individuals have the ability to request
and be granted both access to and
amendment of, if legally authorized,
categories of records from this system
contained on them pursuant to
subsection (d) of the Privacy Act.
Except as noted above, the
Department will implement the
rulemaking as proposed.
List of Subjects in 6 CFR Part 5

For the reasons stated in the
preamble, DHS amends chapter I of title
6, Code of Federal Regulations, as
follows:
PART 5—DISCLOSURE OF RECORDS

34. The DHS/USCG–029 Notice of Arrival
and Departure System of Records consists of
electronic and paper records and will be used
by DHS and its components. The DHS/
USCG–029 Notice of Arrival and Departure
System of Records is a repository of

Jkt 241001
information held by DHS in connection with
its several and varied missions and functions,
including, but not limited to the enforcement
of civil and criminal laws; investigations,
inquiries, and proceedings there under. The
DHS/USCG–029 Notice of Arrival and
Departure System of Records contains
information that is collected by, on behalf of,
in support of, or in cooperation with DHS
and its components and may contain
personally identifiable information collected
by other federal, state, local, tribal, foreign,
or international government agencies.
The Secretary of Homeland Security,
pursuant to 5 U.S.C. 552a(j)(2), exempted this
system from the following provisions of the
Privacy Act: Sections (c)(3), (e)(8), and (g) of
the Privacy Act of 1974, as amended, as is
necessary and appropriate to protect this
information. Further, DHS has exempted
section (c)(3) of the Privacy Act of 1974, as
amended, pursuant to 5 U.S.C. 552a(k)(2), as
is necessary and appropriate to protect this
information.
Exemptions from these particular
subsections are justified, on a case-by-case
basis to be determined at the time a request
is made, for the following reasons:
(a) From subsection (c)(3) (Accounting for
Disclosures) because release of the
accounting of disclosures could alert the
subject of an investigation of an actual or
potential criminal, civil, or regulatory
violation to the existence of that investigation
and reveal investigative interest on the part
of DHS as well as the recipient agency.
Disclosure of the accounting would therefore
present a serious impediment to law
enforcement efforts and/or efforts to preserve
national security. Disclosure of the
accounting would also permit the individual
who is the subject of a record to impede the
investigation, to tamper with witnesses or
evidence, and to avoid detection or
apprehension, which would undermine the
entire investigative process. When an
investigation has been completed,
information on disclosures made may
continue to be exempted if the fact that an
investigation occurred remains sensitive after
completion.
(b) From subsection (e)(8) (Notice on
Individuals) because compliance would
interfere with DHS’s ability to obtain, serve,
and issue subpoenas, warrants, and other law
enforcement mechanisms that may be filed
under seal and could result in disclosure of
investigative techniques, procedures, and
evidence.
(c) From subsection (g)(1) (Civil Remedies)
to the extent that the system is exempt from
other specific subsections of the Privacy Act.

Background
On July 9, 2012, Pilatus Aircraft Ltd.
applied for a type certificate for their
new PC–24 airplane. The PC–24 is an
2 See
https://rgl.faa.gov/ to review the listed
special conditions.
VerDate Sep<11>2014
14:51 Jul 14, 2017
Jkt 241001
aluminum pressurized low-wing
business jet with a T-tail configuration
and retractable undercarriage designed
to meet the commuter category
requirements of part 23. Two Williams
International FJ44–4A Turbofan engines
rated at 3,400 pounds (lbs.) of take-off
thrust, situated in nacelles on each side
of the rear fuselage power the PC–24.
The PC–24 will have a Maximum Takeoff Weight (MTOW) of 17,200 pounds
(7,802 kilograms). It has a maximum
seating capacity of up to ten passengers
and one pilot or two pilots. The airplane
will be certificated for day and night
Visual Flight Rules, Instrument Flight
Rules, and flight into known icing.
The PC–24 is equipped with a
pressure refuel/defuel system. The
applicable regulations do not include
requirements for the pressure-defueling
portion of the system.
Type Certification Basis
Under the provisions of 14 CFR 21.17,
Pilatus Aircraft Ltd. must show that the
PC–24 meets the applicable provisions
of 14 CFR part 23, as amended by
amendments 23–1 through 23–62
thereto.
If the Administrator finds that the
applicable airworthiness regulations
(i.e., 14 CFR part 23) do not contain
adequate or appropriate safety standards
for the PC–24 because of a novel or
unusual design feature, special
conditions are prescribed under the
provisions of § 21.16.
In addition to the applicable
airworthiness regulations and special
conditions, the PC–24 must comply
with the fuel vent and exhaust emission
requirements of 14 CFR part 34, the
noise certification requirements of 14
CFR part 36, and the FAA must issue a
finding of regulatory adequacy pursuant
to section 611 of Public Law 92–574, the
‘‘Noise Control Act of 1972.’’
The FAA issues special conditions, as
defined in § 11.19, under § 11.38 and
they become part of the type
certification basis under § 21.17(a)(2).
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, the FAA would apply
these special conditions to the other
models under § 21.101.
32615
Discussion
As discussed in the ‘‘Background’’
section, the PC–24 will incorporate a
pressure refuel/defuel system. The
defueling capability is considered a
novel design for this type of airplane.
The applicable airworthiness
regulations do not contain adequate or
appropriate safety standards for this
design feature. Mandating additional
requirements by adopting 14 CFR
25.979(e)—which is the part 25 pressure
defuel requirement—mitigates the
concern associated with installation of a
pressure defueling system.
Applicability
As discussed above, these special
conditions are applicable to the PC–24.
Should Pilatus Aircraft Ltd. apply at a
later date for a change to the type
certificate to include another model on
the same type certificate incorporating
the same novel or unusual design
feature, the FAA would apply these
special conditions to that model as well.
Conclusion
This action affects only certain novel
or unusual design features on one model
of airplanes. It is not a rule of general
applicability and it affects only the
applicant who applied to the FAA for
approval of these features on the
airplane.
The substance of these special
conditions has been subjected to the
notice and comments period in several
prior instances—identified above—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, notice and opportunity for
prior public comments hereon are
unnecessary and the FAA finds good
cause, in accordance with 5 U.S.C.
553(b)(3)(B) and 553(d)(3), making these
special conditions effective upon
issuance. 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.

mechanical control system. Even though
the engine control system will be
certificated as part of the engine, the
installation of an engine with an
electronic control system requires
evaluation due to critical environmental
effects and possible effects on or by
other airplane systems. Examples of
critical environmental effects include—
• Indirect effects of lightning;
• Radio interference with other

Background
On July 9, 2012, Pilatus Aircraft Ltd. applied for a type
certificate for their new PC-24 airplane. The PC-24 is an aluminum
pressurized low-wing business jet with a T-tail configuration and
retractable undercarriage designed to meet the commuter category
requirements of part 23. Two Williams International FJ44-4A Turbofan
engines rated at 3,400 pounds (lbs.) of take-off thrust, situated in
nacelles on each side of the rear fuselage power the PC-24. The PC-24
will have a Maximum Take-off Weight (MTOW) of 17,200 pounds (7,802
kilograms). It has a maximum seating capacity of up to ten passengers
and one pilot or two pilots. The airplane will be certificated for day
and night Visual Flight Rules, Instrument Flight Rules, and flight into
known icing.
The PC-24 is equipped with a pressure refuel/defuel system. The
applicable regulations do not include requirements for the pressure-
defueling portion of the system.
Type Certification Basis
Under the provisions of 14 CFR 21.17, Pilatus Aircraft Ltd. must
show that the PC-24 meets the applicable provisions of 14 CFR part 23,
as amended by amendments 23-1 through 23-62 thereto.
If the Administrator finds that the applicable airworthiness
regulations (i.e., 14 CFR part 23) do not contain adequate or
appropriate safety standards for the PC-24 because of a novel or
unusual design feature, special conditions are prescribed under the
provisions of Sec. 21.16.
In addition to the applicable airworthiness regulations and special
conditions, the PC-24 must comply with the fuel vent and exhaust
emission requirements of 14 CFR part 34, the noise certification
requirements of 14 CFR part 36, and the FAA must issue a finding of
regulatory adequacy pursuant to section 611 of Public Law 92-574, the
``Noise Control Act of 1972.''
The FAA issues special conditions, as defined in Sec. 11.19, under
Sec. 11.38 and they become part of the type certification basis under
Sec. 21.17(a)(2).
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, the FAA would apply these special conditions to
the other models under Sec. 21.101.
Novel or Unusual Design Features
The PC-24 will incorporate the following novel or unusual design
features:
Pressure Fueling System with Defuel Capability
Discussion
As discussed in the ``Background'' section, the PC-24 will
incorporate a pressure refuel/defuel system. The defueling capability
is considered a novel design for this type of airplane. The applicable
airworthiness regulations do not contain adequate or appropriate safety
standards for this design feature. Mandating additional requirements by
adopting 14 CFR 25.979(e)--which is the part 25 pressure defuel
requirement--mitigates the concern associated with installation of a
pressure defueling system.
Applicability
As discussed above, these special conditions are applicable to the
PC-24. Should Pilatus Aircraft Ltd. apply at a later date for a change
to the type certificate to include another model on the same type
certificate incorporating the same novel or unusual design feature, the
FAA would apply these special conditions to that model as well.
Conclusion
This action affects only certain novel or unusual design features
on one model of airplanes. It is not a rule of general applicability
and it affects only the applicant who applied to the FAA for approval
of these features on the airplane.
The substance of these special conditions has been subjected to the
notice and comments period in several prior instances--identified
above--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, notice and opportunity for prior public comments hereon are
unnecessary and the FAA finds good cause, in accordance with 5 U.S.C.
553(b)(3)(B) and 553(d)(3), making these special conditions effective
upon issuance. 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.

The Special Conditions
0
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 Pilatus Aircraft Ltd. PC-24 airplanes.
1. Pressure Fueling System
For pressure fueling systems, in addition to Sec. 23.979, the
following applies:
The airplane defueling system--not including fuel tanks and fuel
tank vents--must withstand an ultimate load that is 2.0 times the load
arising from the maximum permissible defueling pressure--positive or
negative--at the airplane fueling connection.
Issued in Kansas City, Missouri, on July 6, 2017.
