AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We propose to supersede Airworthiness Directive (AD) 2013-22-
19, which applies to all Gulfstream Aerospace Corporation Model GV and
GV-SP airplanes. AD 2013-22-19 currently requires inspecting to
determine if fuel boost pumps having a certain part number are
installed,
[[Page 59163]]
replacing the fuel boost pumps having a certain part number, and
revising the airplane maintenance program to include revised
instructions for continued airworthiness. Since we issued AD 2013-22-
19, we have determined that the maintenance or inspection program, as
applicable, must be revised to include new service information. This
proposed AD would continue to require revising the airplane maintenance
program to include a fuel leak check of the fuel boost pumps, using new
service information. We are proposing 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: We must receive comments on this proposed AD by November 17,
2014.
ADDRESSES: You may send comments, using the procedures found in 14 CFR

Discussion
On October 25, 2013, we issued AD 2013-22-19, Amendment 39-17651
(78 FR 72554, December 3, 2013), for all Gulfstream Aerospace
Corporation Model GV and GV-SP airplanes. AD 2013-22-19 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. AD 2013-22-19
resulted from 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 issued AD 2013-22-19 to prevent fuel leakage in combination
with a capacitor clearance issue, which could result in an uncontrolled
fire in the wheel well.
Actions Since AD 2013-22-19, Amendment 39-17651 (78 FR 72554, December
3, 2013), Was Issued
Since we issued AD 2013-22-19, Amendment 39-17651 (78 FR 72554,
December 3, 2013), we have determined that the maintenance or
inspection program, as applicable, must be revised to include new
service information. We became aware that the service information
specified in paragraph (i) of AD 2013-22-19 cannot be used by operators
and does not appropriately address the unsafe condition.
Relevant Service Information
We have reviewed the following Gulfstream Customer Bulletins, which
describe procedures for inspecting and replacing the fuel boost pumps:
Gulfstream V Customer Bulletin 197, dated April 11, 2012
(for Model GV airplanes);
Gulfstream G500 Customer Bulletin 122, dated April 11,
2012 (for Model GV-SP airplanes designated as G500); and
Gulfstream G550 Customer Bulletin 122, dated April 11,
2012 (for Model GV-SP airplanes designated as G500 or G550).
We also reviewed the following service information, which describes
procedures for revising the airplane maintenance or inspection program,
as applicable, to include a fuel leak check of the fuel boost pumps,
and the inspection intervals:
Table 18, ``500 Flight Hours Scheduled Inspection Table,''
in section 05-20-00, of chapter 5, Time Limits/Maintenance Checks, of
the Gulfstream V Maintenance Manual, Revision 23, dated June 20, 2013;
Task 28-26-01, Fuel Boost Pumps--Fuel Leak Check, of
chapter 28, Fuel, of the Gulfstream V Maintenance Manual, Revision 23,

Maintenance Manual, Revision 23, dated June 20, 2013.
FAA's Determination
We are proposing this AD because we evaluated all the relevant
information and determined the unsafe condition described previously is
likely to exist or develop in other products of the same type design.
Proposed AD Requirements
This proposed AD would retain all requirements of AD 2013-22-19,
Amendment 39-17651 (78 FR 72554, December 3, 2013). This proposed AD
also includes new service information for Model GV-SP airplanes
designated as Model G500 for the actions required by paragraphs (g) and
(h) of this proposed AD.
Explanation of ``RC'' Steps in Service Information
The FAA worked in conjunction with industry, under the
Airworthiness Directives Implementation Aviation Rulemaking Committee,
to enhance the AD system. One enhancement was a new process for
annotating which steps in the service information are required for
compliance with an AD. Differentiating these steps from other tasks in
the service information is expected to improve an owner's/operator's
understanding of crucial AD requirements and help provide consistent
judgment in AD compliance. The actions specified in the service
information described previously include steps that are labeled as RC
(required for compliance) because these steps have a direct effect on
detecting, preventing, resolving, or eliminating an identified unsafe
condition. As noted in the specified service information, steps labeled
as RC must be done to comply with the proposed AD. However, steps that
are not labeled as RC are recommended. Those steps that are not labeled
as RC may be deviated from, done as part of other actions, or done
using accepted methods different from those identified in the service
information without obtaining approval of an alternative method of
compliance (AMOC), provided the steps labeled as RC can be done and the
airplane can be put back in a serviceable condition. Any substitutions
or changes to steps labeled as RC will require approval of an AMOC.
Costs of Compliance
We estimate that this proposed AD affects 357 airplanes of U.S.
registry.
We estimate the following costs to comply with this proposed AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------

actions from AD 2013-22-19, Amendment
39-17651 (78 FR 72554, December 3,
2013)].

2013)].
----------------------------------------------------------------------------------------------------------------
We estimate the following costs to do any necessary replacements
that would be required based on the results of the proposed inspection.
We have no way of determining the number of aircraft that might need
these replacements:

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 proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 the proposed
regulation:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Is not a ``significant rule'' under the 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.
List of Subjects in 14 CFR Part 39
