AGENCY:
The U.S. Nuclear Regulatory
Commission (NRC) is making available
the regulatory basis for the ongoing
proposed rulemaking effort to amend its
regulations regarding drug testing
requirements in NRC licensees’ fitness
for duty programs. The regulatory basis
documents the reasoning upon which
the NRC determined rulemaking was the
appropriate course of action. In this
regulatory basis, the NRC recommends
developing a proposed rule that would
enhance the ability of NRC licensees to
detect and deter drug use and the
alignment of the NRC’s regulations with
select drug testing provisions in the U.S.
Department of Health and Human
Services’ ‘‘Mandatory Guidelines for
Federal Workplace Drug Testing
Programs’’ issued in 2008.

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 2012–0223,
dated October 23, 2012 (referred to after
this as the Mandatory Continuing
Airworthiness Information, or ‘‘the
MCAI’’), to correct an unsafe condition
for the specified products. The MCAI
states:
Airbus identified a batch of special
washers, Part Number (P/N)
D5725260120000 and P/N D5725664320000,
which were incorrectly manufactured and
delivered as spares from the supplier
between October 2006 and January 2010. As
a result of these manufacturing defects, the
affected washers differ geometrically from
the design specifications. The results of
further analyses on Airbus A318, A319, A320
and A321 aeroplanes demonstrate that the
affected washers could be seated incorrectly
when installed on aeroplanes, which could
affect the main landing gear (MLG) retraction
jack anchorage fitting bearing installation.
This condition, if not detected and
corrected, could lead to a local stress
concentration which may reduce the fatigue
life of the jack fitting, possibly reducing the
structural integrity of the affected MLG.
For the reasons described above, this
[EASA] AD requires a one-time detailed
visual inspection of the left-hand (LH) and
right-hand (RH) MLG retraction jack
anchorage fitting bearing assemblies to verify
that the special washer is seated correctly
and, depending on findings, the
accomplishment of applicable [related
investigative action and] corrective actions.
The related investigative action is a
detailed inspection of the jack
anchorage fitting for damage, corrosion,
cracks or other defects. Corrective
actions include replacing the special
washer with a new special washer and
repairing the jack anchorage fitting if
there are signs of damage, corrosion, or
other defects. You may obtain further

information by examining the MCAI in
the AD docket.
Relevant Service Information
Airbus has issued Airbus Service
Bulletin A320–57–1169, Revision 01,
dated September 18, 2012, and the
following tasks in Subject 57–26–13,
Attachment—Main Landing Gear, of
Chapter 57, Wings, of the Airbus A318/
A319/A320/A321 Aircraft Maintenance
Manual (AMM), Revision 50, dated
November 1, 2012.
• Task 57–26–13–400–001–A,
Installation of the Bearing Assembly of
the Forward Pintle Pin.
• Task 57–26–13–400–002–A,
Installation of the Bearing Assembly of
the MLG Actuator Attachment.
• Task 57–26–13–400–004–A,
Installation of the Bearing Seals of the
MLG Actuator Bearing Assembly.
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 Proposed AD
and the MCAI or Service Information
Airbus Service Bulletin A320–57–
1169, Revision 01, dated September 18,
2012, specifies to contact the
manufacturer for instructions on how to
repair certain conditions, but this
proposed AD would require repairing
those conditions using a method
approved by either the Manager,
International Branch, ANM–116,
Transport Airplane Directorate, FAA; or
the EASA (or its delegated agent).
Costs of Compliance
Based on the service information, we
estimate that this proposed AD would
affect about 851 products of U.S.
registry. We also estimate that it would
take about 3 work-hours per product to
comply with the basic requirements of
this proposed AD. The average labor
rate is $85 per work-hour. Based on
these figures, we estimate the cost of the
proposed AD on U.S. operators to be
E:\FR\FM\01JYP1.SGM
01JYP1
39192
Federal Register / Vol. 78, No. 126 / Monday, July 1, 2013 / Proposed Rules
$217,005, or $255 per product. In
addition, we estimate that any necessary
follow-on actions would take about 15
work-hours, for a cost of $1,275 per
product. We have received no definitive
data that would enable us to provide
part cost estimates for the on-condition
actions specified in this proposed AD.
We have no way of determining the
number of products that may need these
actions.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation
safety, Incorporation by reference,
Safety.
Authority for This Rulemaking
PART 39—AIRWORTHINESS
DIRECTIVES
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.
tkelley on DSK3SPTVN1PROD with PROPOSALS
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.
We prepared a regulatory evaluation
of the estimated costs to comply with
this proposed AD and placed it in the
AD docket.

AGENCY:
We propose to supersede an
existing airworthiness directive (AD)
that applies to all The Boeing Company
Model 737–100, –200, –200C, –300,
–400, and –500 series airplanes. The
existing AD currently requires repetitive

inspections for discrepancies of each
carriage spindle of the outboard midflaps; repetitive gap checks of the
inboard and outboard carriages of the
outboard mid-flaps to detect fractured
carriage spindles; measuring to ensure
that any new or serviceable carriage
spindle meets minimum allowable
diameter measurements taken at three
locations; repetitive inspections,
measurements, and overhaul of the
carriage spindles; replacement of any
carriage spindle when it has reached its
maximum life limit; and corrective
actions if necessary. Since we issued
that AD, we received a report of failure
of both flap carriages. This proposed AD
would require reducing the life limit of
the carriages, reducing the repetitive
interval for certain inspections and gap
checks for certain carriages. This
proposed AD would also add an option,
for certain replacements, of doing an
inspection, and related investigative and
corrective actions if necessary. We are
proposing this AD to detect and correct
cracked, corroded, or fractured carriage
spindles, which could lead to severe
flap asymmetry, and could result in
reduced control or loss of controllability
of the airplane.
DATES: We must receive comments on
this proposed AD by August 15, 2013.

SUMMARY: We propose to adopt a new airworthiness directive (AD) for all
Airbus Model A318, A319, A320, and A321 series airplanes. This proposed
AD was prompted by a determination that certain special washers used in
the retraction jack anchorage fitting bearing installation in the main
landing gear (MLG) were incorrectly manufactured. This proposed AD
would require an inspection of the left-hand (LH) and right-hand (RH)
MLG retraction jack anchorage fitting bearing assemblies to verify that
the special washer is seated correctly, and related investigative and
corrective actions if necessary. We are proposing this AD to detect and
correct
[[Page 39191]]
installation of incorrectly manufactured special washers, which could
lead to a local stress concentration resulting in possible reduction of
the fatigue life of the jack fitting, and consequent reduction of the
structural integrity of the affected MLG.

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 2012-0223, dated October 23, 2012 (referred to
after this as the Mandatory Continuing Airworthiness Information, or
``the MCAI''), to correct an unsafe condition for the specified
products. The MCAI states:
Airbus identified a batch of special washers, Part Number (P/N)
D5725260120000 and P/N D5725664320000, which were incorrectly
manufactured and delivered as spares from the supplier between
October 2006 and January 2010. As a result of these manufacturing
defects, the affected washers differ geometrically from the design
specifications. The results of further analyses on Airbus A318,
A319, A320 and A321 aeroplanes demonstrate that the affected washers
could be seated incorrectly when installed on aeroplanes, which
could affect the main landing gear (MLG) retraction jack anchorage
fitting bearing installation.
This condition, if not detected and corrected, could lead to a
local stress concentration which may reduce the fatigue life of the
jack fitting, possibly reducing the structural integrity of the
affected MLG.
For the reasons described above, this [EASA] AD requires a one-
time detailed visual inspection of the left-hand (LH) and right-hand
(RH) MLG retraction jack anchorage fitting bearing assemblies to
verify that the special washer is seated correctly and, depending on
findings, the accomplishment of applicable [related investigative
action and] corrective actions.
The related investigative action is a detailed inspection of the jack
anchorage fitting for damage, corrosion, cracks or other defects.
Corrective actions include replacing the special washer with a new
special washer and repairing the jack anchorage fitting if there are
signs of damage, corrosion, or other defects. You may obtain further
information by examining the MCAI in the AD docket.
Relevant Service Information
Airbus has issued Airbus Service Bulletin A320-57-1169, Revision
01, dated September 18, 2012, and the following tasks in Subject 57-26-
13, Attachment--Main Landing Gear, of Chapter 57, Wings, of the Airbus
A318/A319/A320/A321 Aircraft Maintenance Manual (AMM), Revision 50,
dated November 1, 2012.
Task 57-26-13-400-001-A, Installation of the Bearing
Assembly of the Forward Pintle Pin.
Task 57-26-13-400-002-A, Installation of the Bearing
Assembly of the MLG Actuator Attachment.
Task 57-26-13-400-004-A, Installation of the Bearing Seals
of the MLG Actuator Bearing Assembly.
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 Proposed AD and the MCAI or Service
Information
Airbus Service Bulletin A320-57-1169, Revision 01, dated September
18, 2012, specifies to contact the manufacturer for instructions on how
to repair certain conditions, but this proposed AD would require
repairing those conditions using a method approved by either the
Manager, International Branch, ANM-116, Transport Airplane Directorate,
FAA; or the EASA (or its delegated agent).
Costs of Compliance
Based on the service information, we estimate that this proposed AD
would affect about 851 products of U.S. registry. We also estimate that
it would take about 3 work-hours per product to comply with the basic
requirements of this proposed AD. The average labor rate is $85 per
work-hour. Based on these figures, we estimate the cost of the proposed
AD on U.S. operators to be
[[Page 39192]]
$217,005, or $255 per product. In addition, we estimate that any
necessary follow-on actions would take about 15 work-hours, for a cost
of $1,275 per product. We have received no definitive data that would
enable us to provide part cost estimates for the on-condition actions
specified in this proposed AD. We have no way of determining the number
of products that may need these actions.
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.
We prepared a regulatory evaluation of the estimated costs to
comply with this proposed AD and placed it in the AD docket.
