improve the performance of computer
safety models that simulate postulated
SFP accident/fire scenarios. The
petition states that the fourth proposed
regulation would require that licensees
use conservative SFP accident
evaluation models to perform annual
SFP safety evaluations of postulated
complete LOCA scenarios, postulated
partial LOCA scenarios, and postulated
boil-off accident scenarios. The petition
states that the purpose of these
evaluations would be to keep the NRC
informed of the potential consequences
of postulated SFP accident/fire
scenarios as fuel assembles were added,
removed, or reconfigured in licensees’
SFPs.

SUPPLEMENTARY INFORMATION: On
September 12, 2014, FHFA published in
the Federal Register a notice of
proposed rulemaking and request for
comments proposing to revise its
regulations governing Bank
membership, located at 12 CFR part
1263. See 79 FR 54847 (Sept. 12, 2014).
Primarily, the proposed rule would
revise part 1263 to: (1) Require each
Bank member institution and each
applicant for Bank membership to hold
one percent of its assets in ‘‘home
mortgage loans’’ (as that term is defined
in proposed part 1263) in order to
satisfy the statutory requirement that an
institution make long-term home
mortgage loans to be eligible for
membership; (2) require each member to
comply on an ongoing basis, rather than
only at the time of application as at
present, with the foregoing requirement
and, where applicable, with the
requirement that it have at least 10
percent of its assets in ‘‘residential
mortgage loans’’ (as defined in proposed
part 1263); (3) define the term
‘‘insurance company’’ to exclude
captive insurers from Bank membership,
but permit existing captive members to
remain members for five years with
PO 00000
Frm 00002

certain restrictions on their ability to
obtain advances; (4) require a Bank to
obtain and review an insurance
company’s audited financial statements
when considering it for membership;
and (5) clarify the standards by which
an insurance company’s ‘‘principal
place of business’’ is to be identified in
determining the appropriate Bank
district for membership.
The comment period for the proposed
rule was originally set to expire on
November 12, 2014. However, FHFA
has received numerous requests from
the Banks and from other interested
parties for additional time to review the
rule and provide comments. In response
to these requests, FHFA is extending the
comment period by an additional 60
days. This will result in a total comment
period of 120 days, which will expire on
January 12, 2015.
Dated: October 1, 2014.

Federal Aviation
Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
We propose to adopt a new
airworthiness directive (AD) for certain
Beechcraft Corporation Model G58
airplanes. This proposed AD was
prompted by reports of fuel leaks due to
fuel cells that did not properly fit in
Model G58 airplanes. This proposed AD
would require inspecting for and
replacing, as necessary, certain fuel
cells. This proposed AD would also
require inspecting and replacing parts,
as necessary, of the left and right fuel
system installations and correcting
torques on fuel system fittings; and
prohibit future installations of certain
fuel cells. We are proposing this AD to
correct the unsafe condition on these
products.
SUMMARY:
We must receive comments on
this proposed AD by November 21,
2014.

this proposal. Send your comments to
an address listed under the ADDRESSES
section. Include ‘‘Docket No. FAA–
2014–0771; Directorate Identifier 2014–
CE–006–AD’’ at the beginning of your

substantive verbal contact we receive
about this proposed AD.
Discussion
We received seven reports of fuel
leaks in Beechcraft Corporation Model
G58 airplanes. Six fuel leaks were
observed before takeoff or after landing.
One in-flight fuel leak caused large and
rapid loss of fuel and a 24-gallon fuel
imbalance.
An investigation found issues that
may have occurred on the production
line, including fuel cell fit
inconsistencies; improper installation of
fuel components, which may cause
loads on fuel cells and breach of fuel
cells; and improper installation of fuel
hoses and clamps, which may cause fuel
leaks.
Further investigation found
discrepancies and variation in the fit of
the fuel cell on airplanes produced after
December 2011.
These conditions, if not corrected,
could result in significant fuel leakage.
This could lead to an imbalance
condition, which may affect airplane
controllability and/or could lead to an
airplane fire.
Relevant Service Information
We reviewed Beechcraft Mandatory
Service Bulletin SB 28–4127, dated June
2013; and Beechcraft Mandatory Service
Bulletin SB 28–4131, dated November
2013. The service information describes
procedures for inspection of the left and
right fuel system installations and
replacement of parts, as necessary;
inspection for proper torque on fuel
system fittings; and inspection and
replacement, as necessary, of fuel cells.
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. This proposed AD will only
affect fuel cells installed on airplanes
produced after December 2011. This
proposed AD would include prohibiting
the installation of both Beechcraft fuel
cell part numbers produced by FFC and
any PMA part numbers on the Model
G58 airplanes serial numbers (SNs) TH–
2335 through TH–2378, certificated in
any category.
We are evaluating the Beechcraft and
PMA fuel cells that are installed on
airplanes prior to December 2011 for the
same or similar condition and may take
future rulemaking action for airplanes
incorporating these parts.
Proposed AD Requirements
This proposed AD would require
accomplishing the actions specified in
the service information described
previously and prohibit the installation
of certain Beechcraft and FFC PMA fuel
cells.
Costs of Compliance
We estimate that this proposed AD
affects 18 airplanes of U.S. registry.
We estimate the following costs to
comply with this proposed AD:

According to Beechcraft Corporation,
some of the costs of this proposed AD
may be covered under warranty, thereby
reducing the cost impact on affected
individuals. We do not control warranty
coverage for affected individuals. As a
result, we have included all costs in our
cost estimate.

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
The Proposed Amendment
We 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 this 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.
Accordingly, under the authority
delegated to me by the Administrator,
the FAA proposes to amend 14 CFR part
39 as follows:
PART 39—AIRWORTHINESS
DIRECTIVES
1. The authority citation for part 39
continues to read as follows:

[Amended]
2. The FAA amends § 39.13 by adding
the following new airworthiness
directive (AD):

Air Transport Association (ATA) of America
Code: 28, Fuel.
(e) Unsafe Condition
This AD was prompted by reports of fuel
leaks due to fuel cells that did not properly
fit in Model G58 airplanes. We are issuing
this AD to detect and correct improperly
fitting fuel cells. We are also issuing this AD
to correct left and right fuel system
installations and set correct torque on fuel
system fittings for all affected airplanes,
which if not corrected, could result in
significant fuel leakage. This could lead to an
imbalance condition, which may affect
airplane controllability, and/or could lead to
an airplane fire.
(f) Compliance
Comply with this AD within the
compliance times specified in paragraphs (g)
and (h), including all subparagraphs, unless
already done. All of the actions in paragraphs
(g) and (h) must be completed for compliance
with this AD. The actions of Beechcraft
Mandatory Service Bulletin SB 28–4127,
dated June 2013, and Beechcraft Mandatory
Service Bulletin SB 28–4131, dated
November 2013, have numerous overlapping
tasks. Instead of completing the required
actions in paragraph (g) and paragraph (h)
separately, you may complete the actions of
both paragraphs concurrently to avoid
repeating the same tasks unnecessarily. We
recommend reviewing Appendices 1 through
3 for general guidance and suggestions for
task ordering to assist you in not repeating
tasks unnecessarily.

SUMMARY: We propose to adopt a new airworthiness directive (AD) for
certain Beechcraft Corporation Model G58 airplanes. This proposed AD
was prompted by reports of fuel leaks due to fuel cells that did not
properly fit in Model G58 airplanes. This proposed AD would require
inspecting for and replacing, as necessary, certain fuel cells. This
proposed AD would also require inspecting and replacing parts, as
necessary, of the left and right fuel system installations and
correcting torques on fuel system fittings; and prohibit future
installations of certain fuel cells. We are proposing this AD to
correct the unsafe condition on these products.
DATES: We must receive comments on this proposed AD by November 21,
2014.

SUPPLEMENTARY INFORMATION:
Comments Invited
We invite you to send any written relevant data, views, or
arguments about this proposal. Send your comments to an address listed
under the ADDRESSES section. Include ``Docket No. FAA-2014-0771;
Directorate Identifier 2014-CE-006-AD'' at the beginning of your
comments. We specifically invite comments on the overall regulatory,
economic, environmental, and energy aspects of this proposed AD. We
will consider all comments received by the closing date and may amend
this proposed AD because of those comments.
We will post all comments we receive, without change, to https://www.regulations.gov, including any personal information you provide. We
will also post a report summarizing each substantive verbal contact we
receive about this proposed AD.
Discussion
We received seven reports of fuel leaks in Beechcraft Corporation
Model G58 airplanes. Six fuel leaks were observed before takeoff or
after landing. One in-flight fuel leak caused large and rapid loss of
fuel and a 24-gallon fuel imbalance.
An investigation found issues that may have occurred on the
production line, including fuel cell fit inconsistencies; improper
installation of fuel components, which may cause loads on fuel cells
and breach of fuel cells; and improper installation of fuel hoses and
clamps, which may cause fuel leaks.
Further investigation found discrepancies and variation in the fit
of the fuel cell on airplanes produced after December 2011.
These conditions, if not corrected, could result in significant
fuel leakage. This could lead to an imbalance condition, which may
affect airplane controllability and/or could lead to an airplane fire.
Relevant Service Information
We reviewed Beechcraft Mandatory Service Bulletin SB 28-4127, dated
June 2013; and Beechcraft Mandatory Service Bulletin SB 28-4131, dated
November 2013. The service information describes procedures for
inspection of the left and right fuel system installations and
replacement of parts, as necessary; inspection for proper torque on
fuel system fittings; and inspection and replacement, as necessary, of
fuel cells.
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.
This proposed AD will only affect fuel cells installed on airplanes
produced after December 2011. This proposed AD would include
prohibiting the installation of both Beechcraft fuel cell part numbers
produced by FFC and any PMA part numbers on the Model G58 airplanes
serial numbers (SNs) TH-2335 through TH-2378, certificated in any
category.
We are evaluating the Beechcraft and PMA fuel cells that are
installed on airplanes prior to December 2011 for the same or similar
condition and may take future rulemaking action for airplanes
incorporating these parts.
Proposed AD Requirements
This proposed AD would require accomplishing the actions specified
in the service information described previously and prohibit the
installation of certain Beechcraft and FFC PMA fuel cells.
Costs of Compliance
We estimate that this proposed AD affects 18 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
----------------------------------------------------------------------------------------------------------------
* Inspection of fuel cells........ 12 work-hours x $85 Not Applicable....... $1,020 $5,100

----------------------------------------------------------------------------------------------------------------
* Applies to the 5 specific serial numbers on the U.S. registry that may have improperly fitting fuel cells
installed at production.
** Applies to the 11 specific serial numbers on the U.S. registry that must do Part 1 of the service
information.
*** Applies to the 7 specific serial numbers on the U.S. registry, listed in the service information that must
do Part 2 of the service information.
We estimate the following costs to do any necessary installations/
replacements that would be required based on the results of proposed
inspections. We have no way of determining the number of airplanes that
might need these installations/replacements:

----------------------------------------------------------------------------------------------------------------
According to Beechcraft Corporation, some of the costs of this
proposed AD may be covered under warranty, thereby reducing the cost
impact on affected individuals. We do not control warranty coverage for
affected individuals. As a result, we have included all costs in our
cost estimate.
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 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 this 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
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive (AD):
Beechcraft Corporation: Docket No. FAA-2014-0771; Directorate
Identifier 2014-CE-006-AD.
(a) Comments Due Date
We must receive comments by November 21, 2014.
(b) Affected ADs
None.
(c) Applicability
This AD applies to Beechcraft Corporation Model G58 airplanes,
serial numbers (SNs) TH-2335 through TH-2378, certificated in any
category.
[[Page 60387]]
(d) Subject
Joint Aircraft System Component (JASC)/Air Transport Association
(ATA) of America Code: 28, Fuel.
(e) Unsafe Condition
This AD was prompted by reports of fuel leaks due to fuel cells
that did not properly fit in Model G58 airplanes. We are issuing
this AD to detect and correct improperly fitting fuel cells. We are
also issuing this AD to correct left and right fuel system
installations and set correct torque on fuel system fittings for all
affected airplanes, which if not corrected, could result in
significant fuel leakage. This could lead to an imbalance condition,
which may affect airplane controllability, and/or could lead to an
airplane fire.
(f) Compliance
Comply with this AD within the compliance times specified in
paragraphs (g) and (h), including all subparagraphs, unless already
done. All of the actions in paragraphs (g) and (h) must be completed
for compliance with this AD. The actions of Beechcraft Mandatory
Service Bulletin SB 28-4127, dated June 2013, and Beechcraft
Mandatory Service Bulletin SB 28-4131, dated November 2013, have
numerous overlapping tasks. Instead of completing the required
actions in paragraph (g) and paragraph (h) separately, you may
complete the actions of both paragraphs concurrently to avoid
repeating the same tasks unnecessarily. We recommend reviewing
Appendices 1 through 3 for general guidance and suggestions for task
ordering to assist you in not repeating tasks unnecessarily.
