well as on non traditional lenders. Such
provisions would discourage the
participation of many lenders in the
program, which would jeopardize the
utilization of funds in these programs.
Rural Development agrees with the
commenters that this is of particular
concern in light of the need of Rural
Development’s Rural Business—
Cooperative Service to process the
applications for Business and Industry
Loan Guarantees funded with American
Recovery and Reinvestment Act
(Recovery Act) funds pursuant to the
Notice of Funds Availability published
on July 24, 2009 (74 FR 36649).
Instead, Rural Development believes
that it is better to narrow the scope of
a common regulatory platform to the
activities associated with its commercial
lending activities. In doing so, Rural
Development will be able to shift the
focus of the common regulatory
platform from a broad array of
guaranteed loan activities to those
commercial lending activities associated
with its Business Program, including
renewable energy.
Focusing on commercial lending
activities within its Business Program
provides Rural Development the option
of developing a common regulatory
structure based on its current Business
and Industry guaranteed loan
regulations (7 CFR part 4279, subparts A
and B, and 7 CFR part 4287, subpart B)
and on its current Rural Energy for
America Program regulation (7 CFR part
4280, subpart B) and incorporating the
Biorefinery Assistance guaranteed loan
program into this regulatory structure.
By adopting, leveraging, and refining
these existing regulations, Rural
Development believes that this
approach to developing a common
regulatory structure for its commercial
lending activities is preferable to
implementing 7 CFR Part 5001 for
several reasons, as suggested by the
commenters, including, but not
necessarily limited to:
• In contrast to 7 CFR part 5001, the
framework of the current Business and
Industry Loan Guarantee regulations is
well established with stakeholders and
has a proven program delivery track
record.
• Implementing 7 CFR part 5001
would require both lenders and Rural
Development staff to be re-trained in
order to learn a new system. Because
such a complete overhaul of the
Business Program regulations is not
required, it is not appropriate to burden
the Rural Development staff to learn and
implement a completely new system.
• Implementing 7 CFR part 5001
would impede Business Program
funding utilization. The lack of
VerDate Nov<24>2008
15:16 Sep 18, 2009
Jkt 217001
familiarity with the interim rule would
cause a 60 to 90 day standstill in
program delivery at a time when the
program level is at record levels.
Furthermore, implementation of the
interim rule will seriously impede the
Administration’s initiative to use
Recovery Act funds to improve the
Nation’s economy.
In summary, based on its review and
re-examination of 7 CFR Part 5001 and
the comments received, Rural
Development takes the position that,
with some refinement and
enhancement, a common regulatory
structure for guaranteed loans utilizing
the current Business Program
regulations will result in a better and
more efficient regulatory structure than
would be achieved through the
implementation of 7 CFR part 5001.
II. Withdrawal of Interim Rule
Accordingly, the interim final rule

SUPPLEMENTARY INFORMATION:
Sfmt 4700
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to include an airworthiness
directive (AD) that would apply to
certain Boeing Model 727–281
airplanes. That NPRM was published in
the Federal Register on December 23,
2008 (73 FR 78675). That NPRM
proposed to require deactivation of
Rogerson Aircraft Corporation auxiliary
fuel tanks.
Comments
We gave the public the opportunity to
participate in developing this AD. We
considered the comment received.
Boeing supports the NPRM.
Conclusion
SUMMARY: We are adopting a new
airworthiness directive (AD) for certain
Boeing Model 727–281 airplanes. This
AD requires deactivation of Rogerson
Aircraft Corporation auxiliary fuel
tanks. This AD results from fuel system
reviews conducted by the manufacturer,
which identified potential unsafe
conditions but has not provided
Frm 00009
associated corrective actions. We are
issuing this AD to prevent the potential
of ignition sources inside fuel tanks,
which, in combination with flammable
fuel vapors, could result in fuel tank
explosions and consequent loss of the
airplane.
Discussion
DEPARTMENT OF TRANSPORTATION
PO 00000

We reviewed the relevant data,
considered the comment received, and
determined that air safety and the
public interest require adopting the AD
as proposed.
Costs of Compliance
This AD would affect about 17 U.S.registered airplanes. The following table
provides the estimated 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), 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.
You can find our regulatory
evaluation and the estimated costs of
compliance in the AD Docket.

most recent such annual notice. This
rule also removes the citation to Public
Law 106–508 from part 743. Public Law
106–508 is the 2000 renewal of the
Export Administration Act, which has
expired, making the citation obsolete.

SUMMARY: We are adopting a new airworthiness directive (AD) for certain
Boeing Model 727-281 airplanes. This AD requires deactivation of
Rogerson Aircraft Corporation auxiliary fuel tanks. This AD results
from fuel system reviews conducted by the manufacturer, which
identified potential unsafe conditions but has not provided associated
corrective actions. We are issuing this AD to prevent the potential of
ignition sources inside fuel tanks, which, in combination with
flammable fuel vapors, could result in fuel tank explosions and
consequent loss of the airplane.
DATES: This AD is effective October 26, 2009.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an airworthiness directive (AD) that would apply to
certain Boeing Model 727-281 airplanes. That NPRM was published in the
Federal Register on December 23, 2008 (73 FR 78675). That NPRM proposed
to require deactivation of Rogerson Aircraft Corporation auxiliary fuel
tanks.
Comments
We gave the public the opportunity to participate in developing
this AD. We considered the comment received. Boeing supports the NPRM.
Conclusion
We reviewed the relevant data, considered the comment received, and
determined that air safety and the public interest require adopting the
AD as proposed.
Costs of Compliance
This AD would affect about 17 U.S.-registered airplanes. The
following table provides the estimated 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), 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.
You can find our regulatory evaluation and the estimated costs of
compliance in the AD Docket.

Report
(f) Within 60 days after the effective date of this AD, submit a
report to the Manager, Los Angeles Aircraft Certification Office
(ACO), FAA. Information collection requirements in this AD are
approved by the Office of Management and Budget (OMB) under the
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.)
and are assigned OMB Control Number 2120-0056. The report must
include the following information:
(1) The airplane registration and auxiliary tank STC number
installed.
(2) The usage frequency in terms of total number of flights per
year and total number of flights for which the auxiliary tank is
used.
Prevent Usage of Auxiliary Fuel Tanks
(g) Within 90 days after the effective date of this AD,
deactivate the auxiliary fuel tanks, in accordance with a
deactivation procedure approved by the Manager of the Los Angeles
ACO. Any auxiliary tank component that remains on the airplane must
be secured and must have no effect on the continued operational
safety and airworthiness of the airplane. Deactivation may not
result in the need for additional instructions for continued
airworthiness.
Note 1: Appendix A of this AD provides criteria that might need
to be included in the deactivation procedure. Timely approval is
dependent on early submittal of the deactivation procedures.
Note 2: For technical information, contact Dan Zevallos,
Director of Program Management, Rogerson Aircraft Corporation, 2201

Appendix A
Deactivation Criteria
The auxiliary fuel tank deactivation procedure required by
paragraph (g) of this AD might need to address the following
actions.
(1) Permanently drain auxiliary fuel tanks, and clear them of
fuel vapors to eliminate the possibility of out-gassing of fuel
vapors from the emptied auxiliary tank.
Note: If applicable, removing the bladder might help eliminate
out-gassing.
[[Page 48009]]
(2) Disconnect all electrical connections from the fuel quantity
indication system (FQIS), fuel pumps if applicable, float switches,
and all other electrical connections required for auxiliary tank
operation, and stow them at the auxiliary tank interface.
(3) Disconnect all pneumatic connections if applicable, cap them
at the pneumatic source, and secure them.
(4) Disconnect all fuel feed and fuel vent plumbing interfaces
with airplane original equipment manufacturer (OEM) tanks, cap them
at the airplane tank side, and secure them in accordance with a
method approved by the FAA; one approved method is specified in AC
25-8 Auxiliary Fuel Tank Systems Installations. In order to
eliminate the possibility of structural deformation during cabin
decompression, leave open and secure the disconnected auxiliary fuel
tank vent lines.
(5) Pull and collar all circuit breakers used to operate the
auxiliary tank.
(6) Revise the weight and balance document, if required, and
obtain FAA approval.
(7) Amend the applicable sections of the applicable airplane
flight manual (AFM) to indicate that the auxiliary fuel tank is
deactivated. Remove auxiliary fuel tank operating procedures to
ensure that only the OEM fuel system operational procedures are
contained in the AFM. Amend the Limitations Section of the AFM to
indicate that the AFM Supplement for the STC is not in effect. Place
a placard in the flight deck indicating that the auxiliary tank is
deactivated. The AFM revisions specified in this paragraph may be
accomplished by inserting a copy of this AD into the AFM.
(8) Amend the applicable sections of the applicable airplane
maintenance manual to remove auxiliary tank maintenance procedures.
(9) After the auxiliary fuel tank is deactivated, accomplish
procedures such as leak checks and pressure checks deemed necessary
before returning the airplane to service. These procedures must
include verification that the airplane FQIS and fuel distribution
systems have not been adversely affected.
(10) Include with the operator's proposed procedures any
relevant information or additional steps that are deemed necessary
by the operator to comply with the deactivation and return the
airplane to service.
