AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for all
Gulfstream Aerospace Corporation Model GV and GV-SP airplanes. 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. This AD requires inspecting to determine if fuel boost pumps
having a certain part number are installed, replacing the fuel boost
pumps having a certain part number, and revising the airplane
maintenance program to include revised instructions for continued
airworthiness. We are issuing this AD to prevent fuel leakage in
combination with a capacitor clearance issue, which could result in an
uncontrolled fire in the wheel well.
DATES: This AD is effective January 7, 2014.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of January 7,
2014.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would apply to the specified products. The
NPRM published in the Federal Register on December 26, 2012 (77 FR
75908). The NPRM proposed to require doing an inspection to determine
if fuel boost pumps having a certain part number (P/N) are 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 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 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 NPRM (77
FR 75908, December 26, 2012) and the FAA's response to each comment.
Request To Revise the Precipitating Event
Gulfstream Aerospace Corporation (Gulfstream) requested that the
precipitating event in the SUMMARY section of the NPRM (77 FR 75908,
December 26, 2012) be revised to provide clarity not provided elsewhere
in the NPRM--namely, although two distinct failure types have been
reported, there have been no reports of any fuel pump exhibiting both
failure types.
We agree with Gulfstream's request. We agree that the failures in
service were separate events and no single pump was found with both
failure modes present. We have changed the SUMMARY section and
paragraph (e) of this final rule to include language suggested by the
commenter emphasizing the independent nature of the failure modes.
Request To Revise the Statement of Requirements
Gulfstream requested that the statement of requirements in the
SUMMARY section of the NPRM (77 FR 75908, December 26, 2012) be
revised. Gulfstream proposed to revise the wording to read, ``This
proposed AD would require doing an inspection to determine if fuel
boost pumps having a certain part number are installed, replacing the
fuel boost pumps having a certain part number with a later part number,
and revising the airplane maintenance program to include revised
instructions for continued airworthiness for airplanes with the later
pump part number installed.'' Gulfstream stated that the rewording
increases the content clarity in the NPRM.
We disagree with Gulfstream's request to refer to ``later part
numbers'' because this language lacks clarity. This final rule requires
specific part number replacements. Therefore, we would need to use
specific part numbers to identify replacement parts. In addition, the
intent of the SUMMARY section is to provide a brief explanation of the
unsafe condition and corrective actions; therefore, we do not find it
appropriate to include details regarding specific part numbers. We have
not changed this final rule in this regard.
Request To Revise the Discussion Paragraph of the NPRM (77 FR 75908,
December 26, 2012)
Gulfstream requested that the Discussion paragraph of the NPRM (77
FR 75908, December 26, 2012) be revised. Gulfstream proposed revising
the wording to add, ``Additionally, on one other fuel pump component, a
[[Page 72555]]
damaged o-ring between the `wet' and `dry' cavities of the boost pump
resulted in fuel ingress into the dry cavity and outside of the fuel
pump via the electrical pigtail.'' Gulfstream stated that the rewording
clarifies that the component referred to is a fuel pump, and that there
is one recorded incident; also additional information related to the
discovery of the incident is provided.
We agree that the wording suggested by Gulfstream clarifies the
Discussion paragraph of the NPRM (77 FR 75908, December 26, 2012),
which was drawn entirely from paragraph I.B. ``Reason,'' of Gulfstream
V Customer Bulletin 197, dated April 11, 2012; and Gulfstream G550
Customer Bulletin 122, dated April 11, 2012. However, that portion of
the Discussion paragraph is not carried over into this final rule;
therefore, no change is necessary to this final rule in this regard.
Request To Revise the Unsafe Condition
Gulfstream requested that the unsafe condition identified in the
NPRM (77 FR 75908, December 26, 2012) be revised. Gulfstream proposed
to revise the wording to read, ``If not corrected, the issue of the
fuel leakage in combination with the capacitor clearance issue could
result in an uncontrolled fire in the wheel well.'' Gulfstream stated
that the revised description is consistent with the field experience of
independent failure types.
We agree with Gulfstream's request since the rewording provides
more clarity of the unsafe condition. We have revised the SUMMARY
section, the Discussion paragraph, and paragraph (e) of this final rule
to state that fuel leakage in combination with a capacitor clearance
issue could result in an uncontrolled fire in the wheel well.
Request To Change the Title of Certain Service Information
Gulfstream requested that we change the title of certain service
information in the NPRM (77 FR 75908, December 26, 2012). Gulfstream
stated that the correct title for the Gulfstream service information
should be referred to as ``customer bulletins.'' Gulfstream also stated
that the Model GV-SP airplanes include G500 and G550 airplane types, so
a G500 Customer Bulletin reference should be added.
We acknowledge Gulfstream's request to correct citations for
certain service information. We agree that the referenced bulletins
should be referred to as ``customer'' bulletins; we have revised
document citations throughout this final rule accordingly. However,
although we agree that G500 and G550 airplanes are both included in the
Model GV-SP designation, we do not agree to add a reference to a
customer bulletin for G500 airplanes because doing so violates Office
of the Federal Register (OFR) regulations for approval of materials
``incorporated by reference'' in rules. (See 1 CFR 51.1(f).) In general
terms, we may not include elements in a document citation that are not
clearly specified on the document. Therefore, although we agree that
Gulfstream G550 Customer Bulletin 122, dated April 11, 2012, also
applies to G500 airplanes, we do not agree to revise the document
citation in this regard.
Request To Clarify the Differences Between the Proposed AD and the
Service Information Paragraph of the NPRM (77 FR 75908, December 26,
2012)
Gulfstream requested clarification of the Differences Between the
Proposed AD and the Service Information paragraph of the NPRM (77 FR
75908, December 26, 2012) to highlight that the proposed 36-month
compliance time will result in a slightly later completion date than
the compliance time specified in referenced Gulfstream customer
bulletins, and that the compliance time in the proposed AD takes
precedence over that of the referenced Gulfstream customer bulletins.
Gulfstream stated that it acknowledges a difference in compliance time,
but stated that the NPRM does not provide an explanation on the effect
on the completion date.
We partially agree with Gulfstream's request. We agree that this AD
has a slightly different compliance time than that provided in the
service information. In developing an appropriate compliance time, we
considered the safety implications, parts availability, and normal
maintenance schedules for timely accomplishment of the actions in this
AD, while still maintaining an adequate level of safety. We arrived at
the compliance time with the manufacturer's concurrence. In addition,
the Differences Between the Proposed AD and the Service Information
paragraph of the NPRM (77 FR 75908, December 26, 2012) is not restated
in this final rule. We have not changed this final rule in this regard.
Request To Clarify Certain Part Numbers
Gulfstream requested that the part numbers in the NPRM (77 FR
75908, December 26, 2012) be clarified. Gulfstream stated that the word
``Gulfstream'' should be added in front of P/N 1159SCP500-5 and P/N
1159SCP500-7 since the fuel pumps also contain GE part numbers.
We agree with Gulfstream's request. When referencing P/N
1159SCP500-5 and P/N 1159SCP500-7, we have added the word
``Gulfstream'' in front of the part number in paragraphs (g), (h), and
(i) of this AD.
Request To Change the Compliance Time
Gulfstream requested that we change the compliance time in
paragraph (h) of the NPRM (77 FR 75908, December 26, 2012). Gulfstream
proposed to revise the compliance time for the replacement of the fuel
boost pump from ``before further flight'' to ``within 36 months after
the effective date of this AD.''
Gulfstream stated that approximately 2,250 fuel pumps having
Gulfstream P/N 11598SCP500-5 require an upgrade to Gulfstream P/N
1159SCP500-7. Gulfstream stated that there are a limited number of
``seed'' fuel pumps to support this effort. Gulfstream stated that the
Gulfstream-managed program matches customer airplane availability with
supplier shop loading and seed unit availability, which allows for an
upgrade of all affected fuel boost pumps within a 42-month committed
timeframe without undue burden onto operators in terms of aircraft
downtime and missed trips. In addition, Gulfstream stated that a risk
assessment was presented to the FAA in 2010 that supported a change-out
interval of 48 months through a Gulfstream-managed program starting in
October 2011. Gulfstream stated that, based on the risk assessment,
Gulfstream V Customer Bulletin 197, dated April 11, 2012 (for Model GV
airplanes); and Gulfstream G550 Customer Bulletin 122, dated April 11,
2012 (for Model GV-SP airplanes); were issued to recommend replacement
of certain fuel pumps within 42 months since issuance of the service
information.
Gulfstream stated that its proposed change to the compliance time
is consistent with the risk assessment, the intent of the managed
program, and the wording of the Gulfstream and supplier service
information. Gulfstream stated that, in contrast, the requirement to
change out Gulfstream P/N 11598SCP500-5 before the next flight is
unnecessary according to the Gulfstream risk assessment, and has the
potential to severely affect the Gulfstream-managed program, since
needed planning information will not be available to Gulfstream.
We agree with Gulfstream's request to revise the compliance time in
paragraph (h) of this final rule to 36 months for the reasons provided
by the commenter. We have revised paragraph (h) of this AD accordingly.
[[Page 72556]]
Request To Revise Compliance Time for Leak Check Inspection
Gulfstream requested we revise paragraph (i)(2) of the NPRM (77 FR
75908, December 26, 2012) to require the initial inspection before 500
flight hours have elapsed since installation of the Gulfstream P/N
1159SCP500-7 pump, or before further flight if 500 flight hours have
elapsed since installation of the Gulfstream 1159SCP500-7 pump and an
initial fuel leak inspection has not been accomplished.
Gulfstream stated that the inspection referred to in paragraph (g)
of the NPRM (77 FR 75908, December 26, 2012) determines the part number
of the fuel boost pump; therefore, a requirement for a leak check
inspection before further flight is inconsistent with the FAA-accepted
Instructions for Continued Airworthiness, and is only required if the
initial inspection interval of 500 flight hours has been exceeded since
installation of the Gulfstream P/N 1159SCP500-7 standard pump and an
initial leak check inspection has not been accomplished.
We partially agree with the commenter's request. We agree that
mandating the leak check inspection at the same time as the part number
inspection could cause the leak check to be done before 500 flight
hours has elapsed since the installation of the Gulfstream P/N
1159SCP500-7 pump, because the Gulfstream P/N 1159SCP500-7 installation
might have just recently been done. However, we disagree with changing
the AD in this regard because the simplicity of the leak check, in
addition to the airplane already being under inspection in the area,
places minimal burden on the operator. We have not changed this AD in
this regard.
Request To Revise Parts Installation Prohibition
Gulfstream requested we revise paragraph (k) of the NPRM (77 FR
75908, December 26, 2012) to prohibit replacing a fuel boost pump
having Gulfstream P/N 1159SCP500-7 with a fuel boost pump having
Gulfstream P/N 1159SCP500-5. Gulfstream stated that this is to allow a
fuel boost pump having Gulfstream P/N 1159SCP500-5 to be replaced by a
fuel boost pump of the same part number within 36 months after the
effective date of the AD, if a Gulfstream P/N 1159SCP500-7 pump is not
available, and to require that any Gulfstream P/N 1159SCP500-5 pumps
installed for that reason must be replaced with a Gulfstream P/N
1159SCP500-7 pump within 36 months after the effective date of the AD.
Gulfstream stated that its risk assessment supports a replacement
at intervals of 48 months from April 2012, and remains unaffected if a
Gulfstream P/N 1159SCP500-5 pump is replaced with a Gulfstream P/N
1159SCP500-5 pump, since the total number of Gulfstream P/N 1159SCP500-
5 pumps in service at any time is unchanged. Gulfstream stated that its
request is intended to avoid a situation where an airplane is grounded
because a Gulfstream P/N 1159SCP500-5 pump requires replacement for
cause and a Gulfstream P/N 1159SCP500-7 pump is unavailable, but a
Gulfstream P/N 1159SCP500-5 is available.
We disagree with Gulfstream's request to revise paragraph (k) of
this AD. In cases where a part is known to be unairworthy, such as when
it creates an unsafe condition, we might determine that, as of the
effective date of the AD, such a part is not allowed to be installed on
an airplane. ``Parts Installation Prohibition'' paragraphs (like
paragraph (k) of this AD) are intended to prevent an operator from
knowingly installing an unairworthy part on an airplane.
We based the compliance time of 36 months specified in paragraph
(g) of this AD on a risk assessment of the Gulfstream Aerospace
Corporation Model GV and GV-SP fleet performed in August 2010. The risk
assessment did not consider the possibility that additional fuel boost
pumps with Gulfstream P/N 1159SCP500-5 would be introduced into the
fleet during the 36-month compliance time. Therefore, we determined
that the ``Parts Installation Prohibition'' paragraph must prohibit
installation of the affected part as of the effective date of this AD.
We have not changed this AD in this regard. However, under the
provisions of paragraph (l) of this AD, we may approve requests for
adjustments to the compliance time if data are submitted to
substantiate that such an adjustment would provide an acceptable level
of safety.
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:
[Agr]re consistent with the intent that was proposed in
the NPRM (77 FR 75908, December 26, 2012) for correcting the unsafe
condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM (77 FR 75908, December 26, 2012).
We also determined that these changes will not increase the
economic burden on any operator or increase the scope of this AD.
Costs of Compliance
We estimate that this AD affects 357 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:
Estimated Costs

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
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.
