Airworthiness Directives; Gulfstream Aerospace Corporation 
Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are superseding Airworthiness Directive (AD) 2013-22-19 for 
all Gulfstream Aerospace Corporation Model GV and GV-SP airplanes. AD 
2013-22-19 required inspecting to determine if fuel boost pumps having 
a certain part number were installed, replacing the fuel boost pumps 
having a certain part number, and revising the airplane maintenance 
program to include revised Instructions for Continued Airworthiness. 
This new AD reduces the compliance time for revising the airplane 
maintenance or inspection program. This AD was prompted by reports of 
two independent types of failure of the fuel boost pump with overheat 
damage found on the internal components and external housing on one of 
the failure types, and fuel leakage on the other. We are issuing this 
AD to address the unsafe condition on these products.

DATES: This AD is effective May 17, 2017.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of May 17, 2017.
    The Director of the Federal Register approved the incorporation by 
reference of certain other publications listed in this AD as of January 
7, 2014 (78 FR 72554, December 3, 2013).

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a supplemental notice of proposed rulemaking (SNPRM) to 
amend 14 CFR part 39 to supersede AD 2013-22-19, Amendment 39-17651 (78 
FR 72554, December 3, 2013) (``AD 2013-22-19''). AD 2013-22-19 applied 
to all Gulfstream Aerospace Corporation Model GV and GV-SP airplanes. 
The SNPRM published in the Federal Register on December 24, 2015 (80 FR 
80295). We preceded the SNPRM with a notice of proposed rulemaking 
(NPRM) that published in the Federal Register on October 1, 2014 (79 FR 
59162) (``the NPRM''). The NPRM proposed to supersede AD 2013-22-19. 
The NPRM was prompted by reports of two independent types of failure of 
the fuel boost pump with overheat damage on the internal components and 
external housing on one of the failure types, and fuel leakage on the 
other. The SNPRM proposed to reduce the compliance time for revising 
the airplane maintenance or inspection program. We are issuing this

[[Page 17534]]

AD to prevent fuel leakage in combination with a capacitor clearance 
issue, which could result in an uncontrolled fire in the wheel well.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the SNPRM and 
the FAA's response to each comment.

Request for Access to Earlier Revisions of the Service Information

    NetJets requested that we provide a source for earlier revisions of 
the required service information. NetJets stated that the NPRM 
specifies that the required service information is available from 
Gulfstream's Web site. NetJets stated that the Gulfstream Web site 
currently provides only the latest revision of each airplane 
maintenance manual (AMM) without the option to obtain earlier 
revisions, which will be incorporated by reference (IBR) in the AD.
    We acknowledge NetJets' request. While previous revisions of the 
service information are not available through Gulfstream's Web site, 
operators may contact Gulfstream directly to obtain this information as 
specified in paragraph (p)(5) of this AD. We have updated this AD to 
reference the latest service information, which is available to 
operators through Gulfstream's Web site. We have not changed this final 
rule regarding this issue.

Request To Change the Term ``Replacing'' in Paragraph (b) of the 
Proposed AD

    NetJets requested that we define the authority and meaning of the 
term ``replaces'' in regards to ADs. NetJets also requested that we 
revise the FAA's AD Manual, dated May 17, 2010 (FAA-IR-M-8040.1C). 
NetJets stated that ``replaces'' is not defined in the FAA's AD Manual 
or in other FAA guidance. NetJets commented that the FAA AD Manual 
defines the means of changing existing AD requirements to be through a 
``superseding AD action.'' NetJets also stated that the SUMMARY section 
of the SNRPM also uses the term ``supersede.''
    We agree to clarify the use of the term ``replaces'' in regards to 
ADs. The term ``replaces'' in paragraph (b) of this AD is amendatory 
terminology required by the Office of the Federal Register. However, we 
use the term ``supersede'' or ``superseding'' in the SUMMARY section of 
AD actions because the FAA's AD Manual, dated May 17, 2010 (FAA-IR-M-
8040.1C), does not use the term ``replaces'' when referring to an AD 
that supersedes or is superseded by another AD. As stated in the FAA AD 
Manual, we issue a supersedure when we need to correct an error that 
affects the substance of the AD or to expand the scope of the existing 
AD. We expect that the next revision of the FAA's AD Manual will 
incorporate the amendatory terminology required by the Office of the 
Federal Register. No change to this AD is necessary in this regard.

Request To Revise the SNPRM for Airplanes Inspected Under 14 CFR 
91.409(e)

    An anonymous commenter requested that we revise paragraph (i) of 
the proposed AD (in the SNPRM) to include a statement that the proposed 
requirements would not be required for those airplanes inspected under 
a 14 CFR 91.409(e) inspection program. The commenter stated that Task 
28-26-01 is already mandated by the FAA-approved Airworthiness 
Limitations Section (ALS), which already mandates the task to be 
performed per the requirements of the ALS. Therefore, the commenter 
asserts that paragraph (i) of the proposed AD (in the SNPRM) is 
unnecessary for airplanes inspected under a 14 CFR 91.409(e) inspection 
program.
    We disagree with the commenter's request. While 14 CFR 91.409(e) 
requires operators of turbojet multi-engine airplanes to comply with 
the replacement times of life-limited parts, 14 CFR 91.409(e) does not 
require operators to use later revisions of the AMMs that are specified 
in the type certificate. This AD is necessary in order to require 
revising the maintenance or inspection program, as applicable, to 
include the fuel leak check inspection of the fuel boost pumps 
specified in the applicable task identified in paragraph (j) of this 
AD. Paragraph (j) of this AD identifies specific revisions of the AMM, 
which are required for compliance with this AD. We have not changed 
this AD in this regard.

Requests To Refer To Correct Location of Task

    NetJets and an anonymous commenter requested that we revise 
paragraph (j) of the proposed AD (in the SNPRM) to refer to table 12, 
Certification Maintenance Requirements (CMR), in section 05-10-10, 
Airworthiness Limitations, of chapter 05, Time Limits/Maintenance 
Checks, of the applicable Gulfstream AMM. NetJets stated that paragraph 
(j) of the proposed AD (in the SNPRM) instead specifies the use of 
table 18, 500 Flight Hours Scheduled Inspection Table, in section 05-
20-00, Scheduled Maintenance Checks. NetJets and the anonymous 
commenter stated that this task does not exist in section 05-20-00 of 
the current AMM; it is now found in table 12, Certification Maintenance 
Requirements (CMR), in section 05-10-10, Airworthiness Limitations, of 
chapter 05, Time Limits/Maintenance Checks, of the applicable 
Gulfstream AMM.
    We agree with the commenters' requests for the reasons stated 
above. We have updated paragraphs (j)(1), (j)(2), and (j)(3) of this AD 
to refer to the correct table and section where the specified task is 
found. In addition, we have added paragraph (k) to this AD to provide 
credit for actions specified in paragraph (i) of this AD that are done 
before the effective date of this AD using the service information 
specified in paragraph (k) of this AD. We have re-designated subsequent 
paragraphs accordingly.

Request To Add ``or Later FAA-Approved Revision''

    NetJets requested that we revise paragraph (j) of the proposed AD 
(in the SNPRM) to add ``or later FAA-approved revision.'' NetJets 
stated that section 05-20-00, Scheduled Maintenance Checks, of chapter 
05, Time Limits/Maintenance Checks; and task 28-26-01, Fuel Boost 
Pumps--Fuel Leak Check, of chapter 28, Fuel; of the Gulfstream V AMM 
are now at Revision 44, dated June 15, 2016. NetJets commented that 
referring to a previous revision of the AMM would result in an 
immediate petition for approval of an alternate method of compliance 
(AMOC) with the newly revised document. NetJets stated that this narrow 
language would require the operator to obtain an AMOC for each future 
revision of the AMM.
    NetJets further requested that, if the ``later approved revisions'' 
language cannot be added, the latest revisions of the AMMs be added as 
a method of compliance in paragraph (j) of the proposed AD.
    We disagree with the commenter's request to add language allowing 
use of later revisions. We cannot use the phrase ``or later FAA-
approved revisions'' in an AD when referring to the service document. 
Doing so violates Office of the Federal Register's (OFR) regulations 
for approval of materials ``incorporated by reference'' in rules. See 1 
CFR 51.1(f).
    However, as we stated previously, we have updated this AD to refer 
to the current service information. Operators must request approval to 
use later revisions of the service information as an AMOC with this AD 
under the provisions of paragraph (n) of this AD. We have made no 
further change to this AD in this regard.

[[Page 17535]]

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this AD with the changes described previously and minor editorial 
changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
SNPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the SNPRM.
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this AD.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, Section 106, describes the 
authority of the FAA Administrator. Subtitle VII, Aviation Programs, 
describes in more detail the scope of the Agency's authority.
    We are issuing this rulemaking under the authority described in 
Subtitle VII, Part A, Subpart III, Section 44701, ``General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.

Regulatory Findings

    We have determined that this AD will not have federalism 
implications under Executive Order 13132. This AD will not have a 
substantial direct effect on the States, on the relationship between 
the national government and the States, or on the distribution of power 
and responsibilities among the various levels of government.
    For the reasons discussed above, I certify that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979),
    (3) Will not affect intrastate aviation in Alaska, and
    (4) Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
