Abstract
The FAA is superseding Airworthiness Directive (AD) 2020-23- 04, which applied to certain Gulfstream Aerospace Corporation Model GVII-G500 and GVII-G600 airplanes. AD 2020-23-04 required revising the existing airplane flight manual (AFM) and airplane maintenance manual (AMM) to include information pertaining to the fuel boost pump. This AD was prompted by a report of misassembled impellers on the shaft of the fuel boost pump during production. This AD retains the requirements of AD 2020-23-04 and requires inspecting affected fuel boost pumps for proper installation of the impeller shaft key, marking affected fuel boost pumps that pass that inspection, and replacing fuel boost pumps that fail. This AD also limits the installation of affected fuel boost pumps. The FAA is issuing this AD to address the unsafe condition on these products.

(AMM) to include information pertaining to the fuel boost pump. This AD
was prompted by a report of misassembled impellers on the shaft of the
fuel boost pump during production. This AD retains the requirements of
AD 2020-23-04 and requires inspecting affected fuel boost pumps for
proper installation of the impeller shaft key, marking affected fuel
boost pumps that pass that inspection, and replacing fuel boost pumps
that fail. This AD also limits the installation of affected fuel boost
pumps. The FAA is issuing this AD to address the unsafe condition on
these products.

SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to supersede AD 2020-23-04, Amendment 39-21320 (85 FR
71232, November 9, 2020) (AD 2020-23-04). AD 2020-23-04 applied to
certain Gulfstream Aerospace Corporation Model GVII-G500 and GVII-G600
airplanes. The NPRM published in the Federal Register on September 5,
2023 (88 FR 60606). The NPRM was prompted by a report of misassembled
impellers on the shaft of the fuel boost pump during production. In the
NPRM, the FAA proposed to continue to require revising the existing AFM
and AMM to include information pertaining to the fuel boost pump. The
NPRM also proposed to require inspecting affected fuel boost pumps for
proper installation of the impeller shaft key, marking affected fuel
boost pumps that pass that inspection, and replacing fuel boost pumps
that fail. The NPRM also proposed to limit installation of affected
fuel boost pumps. The FAA is issuing this AD to prevent the ignition of
flammable vapors in the fuel tank as a result of frictional heating or
sparks caused by a missing, misplaced, or dislodged impeller shaft key
inside the fuel boost pump. The unsafe condition, if not addressed,
could result in a potential source of ignition in the fuel tank and
consequent fire or explosion.
Discussion of Final Airworthiness Directive
Comments
The FAA received a comment from an anonymous commenter who
supported the NPRM without change.
The FAA received additional comments from Gulfstream Aerospace
Corporation (Gulfstream). The following
[[Page 21433]]
presents the comments received on the NPRM and the FAA's response to
each comment.
Request To Change the Maintenance Manual Version
Gulfstream requested that the FAA change the maintenance manual
revision dates specified in paragraph (g) of the proposed AD to refer
to subsequent dates. Gulfstream stated that GVII-G600 Maintenance
Manual 28-26-04 Fuel Boost Pump-Removal/Installation Procedure, dated
August 31, 2020, was revised March 31, 2023, to include non-technical
changes (including the use of puller tool to reduce risk of damage to
Fuel Boost Pump (FBP) during removal with a caution note to avoid
excess force when removing FBP and a step to record FBP serial number
to determine serviceability). Gulfstream also stated that GVII-G500
Maintenance Manual 12-13-01 Defueling Procedure-Defuel, dated August
31, 2020, and GVII-G600 Maintenance Manual 12-13-01 Defueling
Procedure-Defuel, dated August 31, 2020, were revised on September 30,
2023, due to an administrative error.
The FAA agrees with the request. The revised defueling procedure
requested by Gulfstream is acceptable because it instructs fuel boost
pump maintenance to be performed in a way that addresses the unsafe
condition and it prevents damage to the parts being removed/installed.
The FAA has revised paragraphs (g)(1)(i), (ii), (iii), and (v) of this
AD accordingly.
Request To Change Paragraph (i) of the Proposed AD
Gulfstream requested that the compliance time in paragraph (i) of
the proposed AD be revised from ``replacing the pump before further
flight'' to ``replacing the pump following the completion of the CB
[customer bulletin] before further flight.'' Gulfstream reported the
statement ``this AD requires replacing the pump before further flight
in accordance with the requirements of paragraph (h) of this AD'' in
paragraph (i) of the proposed AD could be misleading. Gulfstream stated
it believes this statement could be misunderstood by operators to mean
that the AD immediately grounds their aircraft.
The FAA agrees with the commenter that paragraph (i) of this AD
should be revised to clarify the intent of this AD. Operators have 24
months to comply with all applicable actions required by paragraph (h)
of this AD. The FAA has revised paragraph (i) of this AD by removing
the reference to ``before further flight'' and specifying that where
the service information says to return a pump, this AD requires that
the pump must be replaced.
Request for Removing GVII-G500 AFM
Gulfstream requested removing reference to ``Gulfstream Aerospace
GVII-G500 Airplane Flight Manual Supplement No. GVII-G500-2020-06,
dated September 8, 2020,'' from paragraph (g)(2)(ii) of the proposed
AD; Gulfstream stated there are no GVII-G500 airplanes in this
configuration, all aircraft have been updated to GVII Block 1 software
configuration, therefore this reference to the airplane flight manual
supplement is not applicable.
The FAA has confirmed with Gulfstream that Gulfstream Aerospace
GVII-G500 Airplane Flight Manual Supplement No. GVII-G500-2020-06,
dated September 8, 2020, is no longer applicable to the existing fleet.
However, Gulfstream Aerospace GVII-G500 Airplane Flight Manual
Supplement No. GVII-G500-2020-06, dated September 8, 2020, is retained
in this AD. Operators may have previously complied with paragraph
(g)(2)(ii) of AD 2020-23-04 using GVII-G500 Airplane Flight Manual
Supplement No. GVII-G500-2020-06, dated September 8, 2020. Therefore,
to provide credit to operators who have already complied with the
service information and reduce the need for alternative method of
compliance (AMOC) requests, the FAA has determined that this AD should
include reference to GVII-G500 Airplane Flight Manual Supplement No.
GVII-G500-2020-06, dated September 8, 2020. No changes have been made
to this AD in this regard.
Conclusion
The FAA reviewed the relevant data, considered any comments
received, and determined that air safety requires adopting this AD as
proposed. Accordingly, the FAA is issuing this AD to address the unsafe
condition on these products. Except for minor editorial changes, and
any other changes described previously, this AD is adopted as proposed
in the NPRM. None of the changes will increase the economic burden on
any operator.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Gulfstream GVII-G500 Customer Bulletin No. 069 and
Gulfstream GVII-G600 Customer Bulletin No. 037, both Revision A, both

Costs of Compliance
The FAA estimates that this AD affects 89 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Incorporate information into AMM and AFM 2 work-hours x $85 per hour $0 $170 $15,130
(retained actions from AD 2020-23-04). = $170.
Impeller shaft key inspection (new 36 work-hours x $85 per 0 3,060 272,340
action). hour = $3,060.
----------------------------------------------------------------------------------------------------------------
The FAA estimates the following costs to do any necessary part
marking and fuel boost pump replacements that would be required based
on the results of the inspection for proper installation. The FAA has
no way of determining the number of aircraft that might need these
actions:
On-Condition Costs
------------------------------------------------------------------------
Cost per
Action Labor cost Parts cost product
------------------------------------------------------------------------
Part marking................. 0.5 work-hour x $10 $52.50
$85 per hour =
$42.50.
Fuel pump replacement (per 10 work-hours x 106,706 107,556
fuel boost pump). $85 per hour =
$850.
------------------------------------------------------------------------
The FAA has included all known costs in its cost estimate.
According to the manufacturer, however, some or all of the costs of
this AD may be covered under warranty, thereby reducing the cost impact
on affected operators.
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.
The FAA is 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) Will not affect intrastate aviation in Alaska, and
(3) 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.
