SUPPLEMENTARY INFORMATION:

I. Background
II. Summary of SIP Revision
III. Proposed Action
IV. Statutory and Executive Order Reviews

I. Background

    Throughout this document, whenever ``we,'' ``us,'' or ``our'' is
used, we mean EPA. On July 18, 1997 (62 FR 38652), EPA promulgated the
1997 PM2.5 NAAQS, including an annual standard of 15.0
micrograms per cubic meter ([mu]g/m\3\) based on a 3-year average of
annual mean PM2.5 concentrations, and a 24-hour (or daily)
standard of 65[mu]g/m\3\ based on a 3-year average of the 98th
percentile of 24-hour concentrations. EPA established the standards
based on significant evidence and numerous health studies demonstrating
that serious health effects are associated with exposures to
PM2.5.
    Following promulgation of a new or revised NAAQS, EPA is required
by the CAA to designate areas throughout the United States as attaining
or not attaining the NAAQS; this designation process is described in
section 107(d)(1) of the CAA. In 1999, EPA and state air quality
agencies initiated the monitoring process for the 1997 PM2.5
NAAQS and, by January 2001, established a complete set of air quality
monitors. On January 5, 2005, EPA promulgated initial air quality
designations for the 1997 PM2.5 NAAQS (70 FR 944), which
became effective on April 5, 2005, based on air quality monitoring data
for calendar years 2001-03.
    On April 14, 2005, EPA promulgated a supplemental rule amending the
agency's initial designations (70 FR 19844), with the same effective
date (April 5, 2005) at 70 FR 944. As a result of this supplemental
rule, PM2.5 nonattainment designations are in effect for 39
areas, comprising 208 counties within 20 states (and the District of
Columbia) nationwide, with a combined population of approximately 88
million. The Huntington Area which is the subject of this rulemaking
was included in the list of areas not attaining the 1997
PM2.5 NAAQS. The West Virginia portion of the Huntington
Area consists of Cabell and Wayne Counties and the Graham Tax District
in Mason County.
    On September 7, 2011 (76 FR 55542), EPA determined that West
Virginia had attained the 1997 PM2.5 NAAQS in the Huntington
Area. That determination was based on complete, quality-assured,
quality-controlled, and certified ambient air monitoring data for the
2008-2010 three-year period that showed the area attained the 1997
PM2.5 NAAQS and continues to attain the standard. The
September 7, 2011 determination suspended the requirements for West
Virginia to submit an attainment demonstration, associated reasonably
available control measures, a reasonable further progress plan,
contingency measures, and other planning SIP revisions related to
attainment of the standard for so long as the nonattainment area
continues to meet the 1997 PM2.5 NAAQS. Section 172(c)(3) of
the CAA requires submission and approval of a comprehensive, accurate,
and current inventory of actual emissions. This proposed approval is
limited to the emissions inventory for the Huntington Area. Separate
action will be taken on the remainder of West Virginia's SIP submittal.

II. Summary of SIP Revision

    The 2002 base year emission inventory submitted by WVDEP on May 28,
2009 for the Huntington Area includes emissions estimates that cover
the general source categories of point sources, non-road mobile
sources, area sources, on-road mobile sources, and biogenic sources.
The pollutants that comprise the inventory are nitrogen oxides
(NOX), volatile organic compounds (VOCs), PM2.5,
coarse particles (PM10), ammonia (NH3) and sulfur
dioxide (SO2). EPA has reviewed the results, procedures and
methodologies for the base year emissions inventory submitted by WVDEP.
The year 2002 was selected by WVDEP as the base year for the emissions
inventory per 40 CFR 51.1008(b). A discussion of the emissions
inventory development as well as the emissions inventory for the
Huntington Area can be found in Appendices C and D of the May 28, 2009
SIP submittal.
    Table 1, below, provides a summary of the annual 2002 emissions of
NOX, VOCs, PM2.5, PM10, NH3
and SO2 for the West Virginia portion of the Huntington Area
submittal.

--------------------------------------------------------------------------------------------------------------------------------------------------------

    The CAA section 172(c)(3) emissions inventory is developed by the
incorporation of data from multiple sources. States were required to
develop and submit to EPA a triennial emissions inventory according to
the Consolidated Emissions Reporting Rule (CERR) for all source
categories (i.e., point, area, nonroad mobile and on-road mobile). The
review and evaluation of the methods used for the emissions inventory
submitted by West Virginia are found in the Technical Support Document
dated August 12, 2010, available online at www.regulations.gov, Docket
No. EPA-R03-OAR-2012-0119. EPA finds that the process used to develop
this emissions inventory for the Huntington Area is adequate to meet
the requirements of CAA section 172(c)(3), the implementing
regulations, and EPA guidance for emission inventories.

III. Proposed Action

    EPA is proposing to approve the 2002 base year emissions inventory
portion of the SIP revision submitted by the State of West Virginia on
May 28, 2009 for the Huntington Area. We have made the determination
that this action is consistent with section 110 of the CAA. EPA is
soliciting public comments on the issues discussed in this document.
These comments will be considered before taking final action.

IV. Statutory and Executive Order Reviews

    Under the CAA, the Administrator is required to approve a SIP
submission that complies with the provisions of the CAA and applicable
Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in
reviewing SIP submissions, EPA's role is to approve state choices,
provided that they meet the criteria of the CAA. Accordingly, this
action merely proposes to approve state law as meeting Federal
requirements and does not impose additional requirements beyond those
imposed by state law. For that reason, this proposed action:
     Is not a ``significant regulatory action'' subject to
review by the Office of Management and Budget under Executive Order
12866 (58 FR 51735, October 4, 1993);
     Does not impose an information collection burden under the
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
     Is certified as not having a significant economic impact
on a substantial number of small entities under the Regulatory
Flexibility Act (5 U.S.C. 601 et seq.);
     Does not contain any unfunded mandate or significantly or
uniquely affect small governments, as described in the Unfunded
Mandates Reform Act of 1995 (Pub. L. 104-4);
     Does not have Federalism implications as specified in
Executive Order 13132 (64 FR 43255, August 10, 1999);
     Is not an economically significant regulatory action based
on health or safety risks subject to Executive Order 13045 (62 FR
19885, April 23, 1997);
     Is not a significant regulatory action subject to
Executive Order 13211 (66 FR 28355, May 22, 2001);
     Is not subject to requirements of Section 12(d) of the
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272
note) because application of those requirements would be inconsistent
with the CAA; and
     Does not provide EPA with the discretionary authority to
address, as appropriate, disproportionate human health or environmental
effects, using practicable and legally permissible methods, under
Executive Order 12898 (59 FR 7629, February 16, 1994).
    In addition, this proposed rule, pertaining to the PM2.5
2002 base year emissions inventory portion of the West Virginia SIP for
the Huntington Area, does not have tribal implications as specified by
Executive Order 13175 (65 FR 67249, November 9, 2000), because the SIP
is not approved to apply in Indian country located in the state, and
EPA notes that it will not impose substantial direct costs on tribal
governments or preempt tribal law.

33 CFR Part 165

[USCG-2008-0238]
RIN 1625-AA00

Safety Zone: Kingsmill Resort Fireworks Display, James River,
Williamsburg, VA

AGENCY: Coast Guard, DHS.

ACTION: Temporary final rule.

-----------------------------------------------------------------------

SUMMARY: The Coast Guard is establishing a 350 foot radius safety

zone on the James River in the vicinity of Kingsmill Resort in
Williamsburg, VA in support of the Kingsmill Resort Fireworks Display.

DATES: This rule is effective from 9 p.m. on May 2, 2008 until 10 p.m.
on May 2, 2008.

ADDRESSES: Documents indicated in this preamble as being available in
the docket are part of docket USCG-2008-0238 and are available online
at www.regulations.gov. They are also available for inspection or
copying at two locations: the Docket Management Facility (M-30), U.S.
Department of Transportation, West Building Ground Floor, Room W12-140,
1200 New Jersey Avenue, SE., Washington, DC 20590, between 9 a.m. and 5
p.m., Monday through Friday, except Federal holidays, and the Sector
Hampton Roads, Norfolk Federal Building, 200 Granby St., 7th Floor,
Norfolk, VA 23510 between 9 a.m. and 2 p.m., Monday through Friday,
except Federal holidays.

FOR FURTHER INFORMATION CONTACT: If you have questions on this
temporary rule, call LT Bill Clark, Chief Waterways Management
Division, Sector Hampton Roads at<PHONE_NUMBER>. If you have questions
on viewing the docket, call Renee V. Wright, Program Manager, Docket
Operations, telephone<PHONE_NUMBER>.

SUPPLEMENTARY INFORMATION:

Regulatory Information

    We did not publish a notice of proposed rulemaking (NPRM) for this
regulation. Under 5 U.S.C. 553(b)(B), the Coast Guard finds that good
cause exists for not publishing an NPRM. Any delay encountered in this
regulation's effective date by publishing a NPRM would be contrary to
public interest since immediate action is needed to prevent vessel
traffic from transiting the specified waters to provide for the safety
of life and property on navigable waters. Additionally, this temporary
safety zone will only be enforced for 1 hour on May 2, 2008 and should
have minimal impact on vessel transits due to the fact that vessels can
safely transit through the zone when authorized by the Captain of the
Port or his Representative and that they are not precluded from using
any portion of the waterway except the safety zone area itself. For the
same reasons above, under 5 U.S.C. 553(d)(3), the Coast Guard finds
that good cause exists for making this rule effective less than 30 days
after publication in the Federal Register.

Background and Purpose

    On May 2, 2008, Kingsmill Resort Destination Services of
Williamsburg, VA will sponsor a fireworks display on the shoreline at
position 37[deg]13'23'' N/76[deg]40'12'' W (NAD 1983). Due to the need
to protect mariners and spectators from the hazards associated with the
fireworks display, vessel traffic will be temporarily restricted within
a 350 foot radius of the fireworks launching site.

Discussion of Rule

    The Coast Guard is establishing a safety zone on specified waters
of the James River within the area bounded by a 350 foot radius circle
centered on position 37[deg]13'23'' N/76[deg]40'12'' W (NAD 1983) in
the vicinity of Kingsmill Resort, Williamsburg, VA. This safety zone
will be established in the interest of public safety during the
Kingsmill Resort Fireworks event and will be enforced from 9 p.m. to 10
p.m. on May 2, 2008. General navigation within the safety zone will be
restricted during the specified date and times. Except for participants
and vessels authorized by the Coast Guard Captain of the Port or his
representative, no person or vessel may enter or remain in the
regulated area.

Regulatory Evaluation

    This rule is not a ``significant regulatory action'' under section
3(f) of Executive Order 12866, Regulatory Planning and Review, and does
not require an assessment of potential costs and benefits under section
6(a)(3) of that Order. The Office of Management and Budget has not
reviewed it under that Order. Although this regulation restricts access
to the safety zone, the effect of this rule will not be significant
because: (i) The safety zone will be in effect for a limited duration;
and (ii) the Coast Guard will make notifications via maritime
advisories so mariners can adjust their plans accordingly.

Small Entities

    Under the Regulatory Flexibility Act (5 U.S.C. 601-612), we have
considered whether this rule would have a significant economic impact
on a substantial number of small entities. The term ``small entities''
comprises small businesses, not-for-profit organizations that are
independently owned and operated and are not dominant in their fields,
and governmental jurisdictions with populations of less than 50,000.
    The Coast Guard certifies under 5 U.S.C. 605(b) that this rule will
not have a significant economic impact on a substantial number of small
entities. This rule will affect the following entities, some of which
may be small entities: The owners or operators of vessels intending to
transit or anchor in a portion of the James River from 9 p.m. to 10
p.m. on May 2, 2008.
    The safety zone will not have a significant economic impact on a
substantial number of small entities because the zone will only be in
place for one hour in the evening when vessel traffic is low. Vessel
traffic can pass safely around the zone. Before the effective period,
we will issue maritime advisories widely available to users of the
river.

Assistance for Small Entities

    Under section 213(a) of the Small Business Regulatory Enforcement
Fairness Act of 1996 (Pub. L. 104-121), we offer to assist small
entities in understanding the rule so that they can better evaluate its
effects on them and participate in the rulemaking process.
    Small businesses may send comments on the actions of Federal
employees who enforce, or otherwise determine compliance with, Federal
regulations to the Small Business and Agriculture Regulatory
Enforcement Ombudsman and the Regional Small Business Regulatory
Fairness Boards. The Ombudsman evaluates these actions annually and
rates each agency's responsiveness to small business. If you wish to
comment on actions by employees of the Coast Guard, call 1-888-REG-FAIR
(1-888-734-3247). The Coast Guard will not retaliate against small
entities that question or complain about this rule or any policy or
action of the Coast Guard.

Collection of Information

    This rule calls for no new collection of information under the
Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520).

Federalism

    A rule has implications for federalism under Executive Order 13132,
Federalism, if it has a substantial direct effect on State or local
governments and would either preempt State law or impose a substantial
direct cost of compliance on them. We have analyzed this rule under
that Order and have determined that it does not have implications for
federalism.

Unfunded Mandates Reform Act

    The Unfunded Mandates Reform Act of 1995 (2 U.S.C. 1531-1538)
requires Federal agencies to assess the effects of their discretionary
regulatory actions. In particular, the Act addresses actions that may
result in the expenditure by a State, local, or tribal government, in
the aggregate, or by the private sector of $100,000,000 or more in any
one year. Though this rule will not result in such

an expenditure, we do discuss the effects of this rule elsewhere in
this preamble.

Taking of Private Property

    This rule will not effect a taking of private property or otherwise
have taking implications under Executive Order 12630, Governmental
Actions and Interference with Constitutionally Protected Property
Rights.

Civil Justice Reform

    This rule meets applicable standards in sections 3(a) and 3(b)(2)
of Executive Order 12988, Civil Justice Reform, to minimize litigation,
eliminate ambiguity, and reduce burden.

Protection of Children

    We have analyzed this rule under Executive Order 13045, Protection
of Children from Environmental Health Risks and Safety Risks. This rule
is not an economically significant rule and does not create an
environmental risk to health or risk to safety that may
disproportionately affect children.

Indian Tribal Governments

    This rule does not have tribal implications under Executive Order
13175, Consultation and Coordination with Indian Tribal Governments,
because it does not have a substantial direct effect on one or more
Indian tribes, on the relationship between the Federal Government and
Indian tribes, or on the distribution of power and responsibilities
between the Federal Government and Indian tribes.

Energy Effects

    We have analyzed this rule under Executive Order 13211, Actions
Concerning Regulations That Significantly Affect Energy Supply,
Distribution, or Use. We have determined that it is not a ``significant
energy action'' under that order because it is not a ``significant
regulatory action'' under Executive Order 12866 and is not likely to
have a significant adverse effect on the supply, distribution, or use
of energy. The Administrator of the Office of Information and
Regulatory Affairs has not designated it as a significant energy
action. Therefore, it does not require a Statement of Energy Effects
under Executive Order 13211.

Technical Standards

    The National Technology Transfer and Advancement Act (NTTAA) (15
U.S.C. 272 note) directs agencies to use voluntary consensus standards
in their regulatory activities unless the agency provides Congress,
through the Office of Management and Budget, with an explanation of why
using these standards would be inconsistent with applicable law or
otherwise impractical. Voluntary consensus standards are technical
standards (e.g., specifications of materials, performance, design, or
operation; test methods; sampling procedures; and related management
systems practices) that are developed or adopted by voluntary consensus
standards bodies.
    This rule does not use technical standards. Therefore, we did not
consider the use of voluntary consensus standards.

Environment

    We have analyzed this rule under Commandant Instruction M16475.lD
which guides the Coast Guard in complying with the National
Environmental Policy Act of 1969 (NEPA) (42 U.S.C. 4321-4370f), and
have concluded that there are no factors in this case that would limit
the use of a categorical exclusion under section 2.B.2 of the
Instruction. Therefore, this rule is categorically excluded, under
figure 2-1, paragraph (34)(g), of the Instruction, from further
environmental documentation because it establishes a safety zone. A
final ``Environmental Analysis Check List'' and a final ``Categorical
Exclusion Determination'' will be available in the docket where
indicated under ADDRESSES.

SUMMARY: We are superseding Airworthiness Directive (AD) 2015-23-12,
which applied to all ATR-GIE Avions de Transport R[eacute]gional Model
ATR42 and ATR72 airplanes. AD 2015-23-12 required identifying the
serial number and part number of the main landing gear (MLG) rear hinge
pins, and replacing pins or the MLG if necessary. This AD retains the
requirements of AD 2015-23-12, requires replacing certain additional
MLG hinge pins, and reduces certain compliance times. This AD was
prompted by a new occurrence of a cracked MLG rear hinge pin. We are
issuing this AD to address the unsafe condition on these products.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2015-23-12, Amendment 39-18329 (80 FR 73096,
November 24, 2015) (``AD 2015-23-12''). AD 2015-23-12 applied to all
ATR-GIE Avions de Transport R[eacute]gional Model ATR42 and ATR72
airplanes. The NPRM published in the Federal Register on May 31, 2017
(82 FR 24906). The NPRM was prompted by a new occurrence of a cracked
MLG rear hinge pin. The NPRM proposed to continue to require
identifying the serial number and part number of the MLG rear hinge
pins, and replacing pins or the MLG if necessary. The NPRM also
proposed to require replacing certain additional MLG hinge pins, and
reducing certain compliance times. We are issuing this AD to detect and
correct cracked rear hinge pins, which could lead to MLG structural
failure, possibly resulting in collapse of the MLG and consequent
injury to the occupants of the airplane.
    The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Union, has issued EASA
Airworthiness Directive 2016-0135, dated July 8, 2016 (referred to
after this as the Mandatory Continuing Airworthiness Information, or
``the MCAI''), to correct an unsafe condition for all ATR-GIE Avions de
Transport R[eacute]gional Model ATR42 and ATR72 airplanes. The MCAI
states:

    Prompted by cases of rupture of main landing gear (MLG) rear
hinge pin part number (P/N) D61000 encountered in service in 1994
and 1996, DGAC [Direction G[eacute]n[eacute]rale de l'Aviation
Civile] France issued AD 96-131-064 (B) for ATR42 aeroplanes and AD
96-096-029 (B) for ATR72 aeroplanes to require inspection and,
depending on findings, corrective action. Since those [French] ADs
were issued, new occurrences of cracked rear hinge pin P/N [part
number] D61000 were reported on ATR72 MLG. The result of subsequent
investigation revealed that the affected pins were subjected to a
non-detected thermal abuse done in production during grinding
process. Analysis also showed that other MLG pin P/N's could be
affected by the same production issue.
    This condition, if not detected and corrected, could lead to
structural failure and consequent collapse of the MLG, possibly
resulting in damage to the aeroplane and injury to the occupants.
    To address this potential unsafe condition, EASA issued AD 2014-
0074 [which corresponds to FAA AD 2015-23-12] to require inspection
and, depending on findings, replacement of affected pins.
    After EASA AD 2014-0074 was issued, a new occurrence was
reported of a cracked MLG hinge pin P/N D62055 installed on the MLG
Side Brace of an ATR42 aeroplane. This new occurrence was also
identified as related to a non-detected thermal abuse done in
production during grinding process.
    Prompted by this new occurrence, Messier Bugatti Dowty (MBD)
updated the list of MLG hinge pins affected by this unsafe condition
by adding serial numbers (S/N), which were previously not considered
by EASA AD 2014-0074. In addition, it was determined that the
compliance time for replacement of pins with P/N D62055 must be
reduced. The six affected MBD Service Bulletins (SB) were revised
accordingly, and six new ones were also published to address this
issue.
    For the reasons described above, this [EASA] AD retains the
requirements of EASA AD 2014-0074, which is superseded, but
addresses an expanded MLG hinge pin population with appropriate
compliance time(s).

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2017-
0516.

Comments

    We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM or on the determination of
the cost to the public.

Conclusion

    We reviewed the available data and determined that air safety and
the public interest require adopting this AD as proposed except for
minor editorial changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    Messier-Bugatti-Dowty has issued the following service information,
which describes procedures for inspecting and replacing the MLG hinge
pin. These documents are distinct since they apply to different
airplane models and different MLG hinge pin part numbers.

    This service information is reasonably available because the
interested parties have access to it through their normal course of
business or by the means identified in the ADDRESSES section.

Costs of Compliance

    We estimate that this AD will affect 63 airplanes of U.S. registry.

    The actions required by AD 2015-23-12, and retained in this AD take
about 8 work-hours per product, at an average labor rate of $85 per
work-hour. Required parts will cost about $16,000 per product. Based on
these figures, the estimated cost of the actions that are required by
AD 2015-23-12 is $16,680 per product.
    We also estimate that it will take about 8 work-hours per product
to comply with the basic requirements of this AD. The average labor
rate is $85 per work-hour. Required parts will cost about $16,000 per
product. Based on these figures, we estimate the cost of this AD on
U.S. operators to be $1,050,840, or $16,680 per product.
    According to the manufacturer, some of the costs of this 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.
    This AD is issued in accordance with authority delegated by the
Executive Director, Aircraft Certification Service, as authorized by
FAA Order 8000.51C. In accordance with that order, issuance of ADs is
normally a function of the Compliance and Airworthiness Division, but
during this transition period, the Executive Director has delegated the
authority to issue ADs applicable to transport category airplanes to
the Director of the System Oversight Division.

Regulatory Findings

    We determined that 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 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.

[Docket No. FAA-2008-0520; Directorate Identifier 2008-NM-018-AD]
RIN 2120-AA64

Airworthiness Directives; Boeing Model 777-200 Series Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to adopt a new airworthiness directive (AD) for
certain Boeing Model 777-200 series airplanes. This proposed AD would
require repetitive inspections for any wrinkle in certain external skin
panels, and for cracking at the fuselage bulkhead shear tie end
fastener locations at certain stations of section 48 of the fuselage;
and doing related investigative and corrective actions if necessary.
This proposed AD results from a report of cracks found in the external
skin on the left and right sides of the Section 48 panel of the
fuselage on two airplanes with skin wrinkles found at two of the
external crack locations. We are proposing this AD to detect and
correct wrinkles and cracks in certain external skin panels of Section
48, which could join together and result in reduced structural
integrity of support structure for the vertical and horizontal
stabilizers and inability of the airplane to sustain limit loads.

DATES: We must receive comments on this proposed AD by June 23, 2008.

ADDRESSES: You may send comments by any of the following methods:
     Federal eRulemaking Portal: Go to http://

Discussion

    We have received a report of cracks found in the external skin on
the left and right sides of the section 48 panel of the fuselage on two
airplanes. There were ten external skin cracks on one airplane with
22,732 total flight hours and 20,286 total flight cycles; the cracks
were 0.20 to 0.50 inch in length at

Stations 2195.75 and 2221.65, between Stringers 6 to 10 on the left and
right sides. In addition, skin wrinkles 4.5 and 5.0 inches long and 1.0
inch wide and 0.014 inch deep were found at two of the external skin
crack locations. A second report indicated that three external skin
cracks, 0.12 to 0.20 inches in length were found at Station 2195.75,
above Stringer 7 on the left side, on an airplane with 22,147 total
flight hours and 19,281 total flight cycles. This condition, if not
corrected, could result in reduced structural integrity of support
structure for the vertical and horizontal stabilizers and inability of
the airplane to sustain limit loads.

Relevant Service Information

    We have reviewed Boeing Alert Service Bulletin 777-53A0051, dated
November 8, 2007. The alert service bulletin describes procedures for
repetitive general visual inspections for any wrinkle of the external
skin at Stations 2195.75, 2221.65, and 2245.70 of the Section 48 panel
of the fuselage, between stringers 5 and 10 on the left and right
sides. The service bulletin also describes procedures for repetitive
high frequency eddy current (HFEC) and detailed inspections for
cracking at the fuselage bulkhead shear tie end fastener locations of
the external skin at Stations 2195.75, 2221.65, and 2245.70 of the
section 48 panel of the fuselage; between stringers 5 and 10 on the
left and right sides. In addition, the service bulletin describes
performing related investigative and corrective actions if necessary.
The corrective actions include removing any skin wrinkle, repairing any
skin crack, and installing a skin repair if any wrinkle or crack is
found. The related investigative actions include an internal HFEC
inspection of the repair doubler edge row fasteners for cracking if a
skin repair is installed. The service bulletin also recommends
contacting Boeing for repair data if any crack is found that is 1.0 or
more inches in length.
    The compliance times for the inspections specified in the service
bulletin are as follows:
     General visual and external HFEC inspections for any
wrinkle and cracking of the skin panels and bulkhead shear tie end
fastener locations at Stations 2195.75, 2221.65, and 2245.70 of the
Section 48 panel of the fuselage, between stringers 5 and 10: Before
16,000 total flight cycles or within 2,300 flight cycles after the date
on the service bulletin, whichever occurs later. If no wrinkle or skin
crack is found, the service bulletin specifies repeating the
inspections thereafter at intervals not to exceed 4,500 flight cycles.
     Internal HFEC inspection of the repair doubler shear tie
end fasteners and external and internal detailed inspection of the
tripler, doubler, skin, shear tie, stringer, or fuselage bulkhead
(fastener locations): Within 30,000 flight cycles after installation of
the repair.
     Internal HFEC inspection of the repair doubler edge row
fasteners and external and internal detailed inspection of the tripler,
doubler, skin, shear tie, stringer or fuselage bulkhead within the
repair area: Before 30,000 total flight cycles, or within 16,000 flight
cycles after installation of the repair, whichever occurs first. If no
cracking is found, the service bulletin describes repeating the
inspections thereafter at intervals not to exceed 16,000 flight cycles.
If any crack is found, the service bulletin recommends contacting
Boeing for repair data and repairing.

FAA's Determination and Requirements of This Proposed AD

    We are proposing this AD because we evaluated all 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 would require accomplishing the actions specified in
the service information described previously, except as discussed under
``Difference Between the Proposed AD and Service Information.''

Difference Between the Proposed AD and Service Information

    The alert service bulletin specifies to contact the manufacturer
for instructions on how to repair certain conditions, but this proposed
AD would require repairing those conditions in one of the following
ways:
     Using a method that we approve; or
     Using data that meet the certification basis of the
airplane, and that have been approved by an Authorized Representative
for the Boeing Commercial Airplanes Delegation Option Authorization
Organization whom we have authorized to make those findings.

Costs of Compliance

    We estimate that the inspections in this proposed AD would affect
13 airplanes of U.S. registry. We also estimate that it would take
about 15 work-hours per product to comply with this proposed AD. The
average labor rate is $80 per work-hour. Based on these figures, we
estimate the cost of this proposed AD to the U.S. operators to be
$15,600, or $1,200 per product, per inspection cycle.

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.
    You can find our regulatory evaluation and the estimated costs of
compliance in the AD Docket.
