Reserve requires specific agreements to
be executed. Information regarding
these agreements, as set forth in
Operating Circular No. 10, and Discount
Window operation can be found at
www.frbdiscountwindow.org. These
agreements include arrangements for the
pledging of collateral to secure
advances. All extensions of credit must
be secured to the satisfaction of the
lending Federal Reserve Bank by
collateral that is acceptable for that
purpose. Depository institutions that do
not envision using the Discount
Window in the ordinary course of
events are encouraged to execute the
necessary documents because a need for
Discount Window credit could arise
suddenly and unexpectedly.
IV. Request for Comment
This is a crucial time for depository
institutions, including credit unions, to
reflect on the recent financial crisis and
ongoing economic events and address
potential deficiencies in their funding
and liquidity risk management
capabilities. Access to a contingent
liquidity provider that can back up
market sources of liquidity is an
essential component of these
capabilities that must be met. Credit
unions can use membership in CLF or
access with a Discount Window facility
(and/or a combination of the two) to
meet this need. Since USC Bridge will
need to discontinue its role as a CLF
agent member intermediary, a credit
union currently covered under an agent
membership (i.e, by belonging to a retail
corporate credit union) will lose access
to CLF unless it takes action to become
a regular member or join a new agent
member that acquires CLF membership
stock on the credit union’s behalf.
The Board invites comment on the
issues raised in this ANPR. To facilitate
consideration of the public’s views,
please address your comments to the
questions set forth below on each issue,
and organize and identify them by
corresponding question number so that
each question is addressed separately.
To maximize the value of public input
on each issue, it is also important that
commenters provide and explain the
reasons that support each of their
opinions. There will be a further
opportunity to comment on these issues
should the Board issue a proposed rule.
(1) What are the standards and
provisions, along with associated
considerations, that should accompany
a requirement for federally insured
credit unions to maintain access to
backup federal liquidity sources for use
in times of financial emergency and
distressed economic circumstances?
Should an NCUA requirement to
VerDate Mar<15>2010
19:15 Dec 21, 2011
Jkt 226001
maintain access to backup federal
liquidity sources contain an exemption
for credit unions under a certain asset
threshold, and if so, what should that
threshold be?
(2) Are there other sources of credit
beyond the CLF and Discount Window
the Board should consider as acceptable
to satisfy the need for a backup federal
liquidity source? For example, would a
credit union’s maintenance of a certain
percentage of its assets in highly liquid
(maturity of 90 days or less) Treasury
securities satisfy the need? If so, what is
the appropriate percentage? Also, how
should NCUA ensure that these
securities are available to be pledged or
sold?
(3) How can CLF best play a role in
the immediate term upon USC Bridge’s
wind down and over the long term in
satisfying a credit union’s need for a
contingency liquidity source? How
should that role be executed? Are
changes to the CLF statute to modernize
the way the CLF functions over the long
term warranted, and if so what changes
should be pursued? For example,
should the CLF function more like the
Discount Window?
(4) What is the best way for credit
unions to access CLF (e.g., either
directly or through an agent)? Should
corporate credit unions continue to play
a role and, if so, to what extent should
they be encouraged to purchase CLF
stock as agents for natural person credit
unions?
The Board also seeks comment on
how a proposed rule could be
implemented to maximize economic
benefit while minimizing regulatory
burden on credit unions. Please
comment on any other relevant issues
the Board has not considered.
By the National Credit Union
Administration Board on December 15, 2011.

ACTION:
We propose to adopt a new
airworthiness directive (AD) for all
Airbus Model A300 B4–600, B4–600R,
and F4–600R series airplanes, and
Model C4–605R Variant F airplanes
(collectively called A300–600 series
airplanes), and Model A310 series
airplanes. This proposed AD was
prompted by a report of a crack in the
forward cargo door selector valve pipe
located in the avionics bay opposite to
line replaceable unit racking. This
proposed AD would require replacing a
certain aluminum high pressure pipe
with a new corrosion resistant stainless
steel pipe. We are proposing this AD to
prevent cracking in the forward cargo
door selector valve pipe which could
impact the 90 VU avionics line
replaceable unit, and could result in
multiple computer failures, affecting
flight safety.

Discussion
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Community, has issued EASA
Airworthiness Directive 2011–0085,
dated May 12, 2011 (corrected May 31,
2011) (referred to after this as ‘‘the
MCAI’’), to correct an unsafe condition
for the specified products. The MCAI
states:
An A300–600 operator has reported a
hydraulic leak at the forward cargo door area.
After further investigation, the forward cargo
door selector valve pipe Part Number (P/N)
A5231006100300, located in the avionics bay
opposite to Line Replaceable Unit (LRU)
racking, was found cracked.
This condition, if not detected and
corrected, can impact the 90 VU avionics
LRU, which could result in multiple
computer failures, affecting flight safety.
For the reasons described above, this AD
requires the replacement of the aluminum
pipe P/N A5231006100300 with a stainless
steel pipe P/N A5231007000600.
This [EASA] AD has been corrected to
make clear that the use of Airbus SB A310–
52–2067 and Airbus SB A300–52–6065 at
original issue is acceptable to comply with
paragraph (1) of this [EASA] AD, unless,
VerDate Mar<15>2010
19:15 Dec 21, 2011
Jkt 226001
inadvertently, the high pressure pipe P/N
A5231007000600 has been replaced in
service, after original issue of the SB’s
accomplishment, with P/N A5231006100300.
You may obtain further information by
examining the MCAI in the AD docket.
Relevant Service Information
Airbus has issued Mandatory Service
Bulletins A300–52–6065, Revision 01,
dated July 5, 2010; and A310–52–2067,
Revision 01, dated July 5, 2010. The
actions described in this service
information are intended to correct the
unsafe condition identified in the
MCAI.
FAA’s Determination and Requirements
of This Proposed AD
This product has been approved by
the aviation authority of another
country, and is approved for operation
in the United States. Pursuant to our
bilateral agreement with the State of
Design Authority, we have been notified
of the unsafe condition described in the
MCAI and service information
referenced above. We are proposing this
AD because we evaluated all pertinent
information and determined an unsafe
condition exists and is likely to exist or
develop on other products of the same
type design.
Differences Between This AD and the
MCAI or Service Information
This AD differs from the MCAI and/
or service information as follows: The
MCAI specifies that installation of P/N
A5231006100300 is not allowed after
modification. However, this AD does
not allow installation of P/N
A5231006100300 as of the effective date
of this AD.
Costs of Compliance
Based on the service information, we
estimate that this proposed AD would
affect about 152 products of U.S.
registry. We also estimate that it would
take about 4 work-hours per product to
comply with the basic requirements of
this proposed AD. The average labor
rate is $85 per work-hour. Required
parts would cost about $0 per product.
Where the service information lists
required parts costs that are covered
under warranty, we have assumed that
there will be no charge for these parts.
As we do not control warranty coverage
for affected parties, some parties may
incur costs higher than estimated here.
Based on these figures, we estimate the
cost of the proposed AD on U.S.
operators to be $51,680, or $340 per
product.

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); 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.
We prepared a regulatory evaluation
of the estimated costs to comply with
this proposed AD and placed it in the
AD docket.

airplanes; Model A330–223F and –243F
airplanes; and Model A340–200, –300,

proposed AD was prompted by a report
that during the evaluation of specific
engine failure cases at take-off on Airbus
flight simulators. It has been shown that
with flight control primary computer
(FCPC)1 inoperative, in worst case
scenario, when FCPC2 and FCPC3 resets
occur during rotation at take off, a
transient loss of elevator control
associated with a temporary incorrect
flight control law reconfiguration could
occur. This proposed AD would require
revising the Limitations section of the
applicable airplane flight manual. We
are proposing this AD to prevent
movement of the elevators to zero
position, which could result in inducing
a pitch down movement instead of a
pitch up movement needed for lift off,
resulting in loss of controllability of the
airplane.

located in the avionics bay opposite to Line Replaceable Unit (LRU)
racking, was found cracked.
This condition, if not detected and corrected, can impact the 90
VU avionics LRU, which could result in multiple computer failures,
affecting flight safety.
For the reasons described above, this AD requires the
replacement of the aluminum pipe P/N A5231006100300 with a stainless
steel pipe P/N A5231007000600.
This [EASA] AD has been corrected to make clear that the use of
Airbus SB A310-52-2067 and Airbus SB A300-52-6065 at original issue
is acceptable to comply with paragraph (1) of this [EASA] AD,
unless, inadvertently, the high pressure pipe P/N A5231007000600 has
been replaced in service, after original issue of the SB's
accomplishment, with P/N A5231006100300.
You may obtain further information by examining the MCAI in the AD
docket.
Relevant Service Information
Airbus has issued Mandatory Service Bulletins A300-52-6065,
Revision 01, dated July 5, 2010; and A310-52-2067, Revision 01, dated
July 5, 2010. The actions described in this service information are
intended to correct the unsafe condition identified in the MCAI.
FAA's Determination and Requirements of This Proposed AD
This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to our bilateral agreement with the State of Design Authority, we have
been notified of the unsafe condition described in the MCAI and service
information referenced above. We are proposing this AD because we
evaluated all pertinent information and determined an unsafe condition
exists and is likely to exist or develop on other products of the same
type design.
Differences Between This AD and the MCAI or Service Information
This AD differs from the MCAI and/or service information as
follows: The MCAI specifies that installation of P/N A5231006100300 is
not allowed after modification. However, this AD does not allow
installation of P/N A5231006100300 as of the effective date of this AD.
Costs of Compliance
Based on the service information, we estimate that this proposed AD
would affect about 152 products of U.S. registry. We also estimate that
it would take about 4 work-hours per product to comply with the basic
requirements of this proposed AD. The average labor rate is $85 per
work-hour. Required parts would cost about $0 per product. Where the
service information lists required parts costs that are covered under
warranty, we have assumed that there will be no charge for these parts.
As we do not control warranty coverage for affected parties, some
parties may incur costs higher than estimated here. Based on these
figures, we estimate the cost of the proposed AD on U.S. operators to
be $51,680, or $340 per product.
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); 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.
We prepared a regulatory evaluation of the estimated costs to
comply with this proposed AD and placed it in the AD docket.
