Airworthiness Directives; Gulfstream Aerospace Corporation 
Airplanes

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:

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.
