SUPPLEMENTARY INFORMATION:

Background

    The FAA has received a report indicating that a crack was found on 
the web attachment flange of the center wing upper forward corner 
fitting. Loose fasteners in the wing station 220 wing joint at the 
front beam web can cause internal load redistribution and consequent 
cracked center wing upper and lower corner fittings and failed 
fasteners in those fittings. This condition, if not addressed, could 
result in reduced structural integrity of the airplane and loss of 
control of the airplane. The FAA is issuing this AD to address the 
unsafe condition on these products.

FAA's Determination

    The FAA is issuing this AD because the agency has determined the 
unsafe condition described previously is likely to exist or develop in 
other products of the same type design.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Lockheed Martin Aeronautics Company Alert Service 
Bulletin A382-57-99, Revision 1, dated February 17, 2021. This service 
information specifies procedures for an eddy current surface scan for 
cracks of the center wing upper and lower forward corner fittings and 
fasteners (including the exterior of the vertical flange of the corner 
fitting common to the front beam web and interior surfaces of the 
corner fitting horizontal and vertical flanges common to the beam cap), 
a torque check of left and right outer-wing-to-center-wing front-beam-
web-joint-splice-angle fasteners (including checking for any loose, 
sheared, broken, or missing fasteners), retorqueing the outer-wing-to-
center-wing front-beam-web-joint-splice-angle fasteners, and repair or 
replacement. 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.

AD Requirements

    This AD requires accomplishing the actions specified in the service 
information already described, except as discussed under ``Differences 
Between this AD and the Service Information.''

Differences Between This AD and the Service Information

    Lockheed Martin Aeronautics Company Alert Service Bulletin A382-57-
99, Revision 1, dated February 17, 2021, applies to Model 382, 382B, 
382E, 382F, and 382G airplanes. This AD applies to Model C-130A, C-
130B, C-130BL, C-130E, C-130H, C-130H-30, C-130J, C-130J-30, EC-130Q, 
HC-130H, KC-130H, NC-130B, NC-130, and WC-130H airplanes as well as the 
airplanes specified in Lockheed Martin Aeronautics Company Alert 
Service Bulletin A382-57-99, Revision 1, dated February 17, 2021. The 
FAA has confirmed that all airplanes identified in paragraph (c) of 
this AD can comply with the actions specified in Lockheed Martin 
Aeronautics Company Alert Service Bulletin A382-57-99, Revision 1, 
dated February 17, 2021.

Impact on Intrastate Aviation in Alaska

    In light of the heavy reliance on aviation for intrastate 
transportation in Alaska, the FAA has fully considered the effects of 
this AD (including costs to be borne by affected operators) from the 
earliest possible stages of AD development. This AD is based on those 
considerations, and was developed with regard to minimizing the 
economic impact on operators to the extent possible, consistent with 
the safety objectives of this AD. In any event, the Federal Aviation 
Regulations require operators to correct an unsafe condition identified 
on an airplane to ensure operation of that airplane in an airworthy 
condition. The FAA has determined in this case that the requirements 
are necessary and the indirect costs would be outweighed by the safety 
benefits of the AD.

Justification for Immediate Adoption and Determination of the Effective 
Date

    Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5 
U.S.C. 551 et seq.) authorizes agencies to dispense with notice and 
comment procedures for rules when the agency, for ``good cause,'' finds 
that those procedures are ``impracticable, unnecessary, or contrary to 
the public interest.'' Under this section, an agency, upon finding good 
cause, may issue a final rule without providing notice and seeking 
comment prior to issuance. Further, section 553(d) of the APA 
authorizes agencies to make rules effective in less than thirty days, 
upon a finding of good cause.
    An unsafe condition exists that requires the immediate adoption of 
this AD without providing an opportunity for public comments prior to 
adoption. The FAA has found that the risk to the flying public 
justifies forgoing notice and comment prior to adoption of this rule 
because loose fasteners in the wing station 220 wing joint at the front 
beam web can cause internal load redistribution, and consequent cracked 
center wing upper and lower corner fittings and failed fasteners in 
those fittings, resulting in reduced structural integrity of the 
airplane and loss of control of the airplane. Accordingly, notice and 
opportunity for prior public comment are impracticable and contrary to 
the public interest pursuant to 5 U.S.C. 553(b)(3)(B).
    In addition, the FAA finds that good cause exists pursuant to 5 
U.S.C. 553(d) for making this amendment effective in less than 30 days, 
for the same reasons the FAA found good cause to forgo notice and 
comment.

Comments Invited

    The FAA invites you to send any written data, views, or arguments 
about this final rule. Send your comments to an address listed under 
ADDRESSES. Include Docket No. FAA-2021-0341 and Project Identifier AD-
2021-00325-T at the beginning of your comments. The most helpful 
comments reference a specific portion of the final rule, explain the 
reason for any recommended change, and include supporting data. The FAA 
will consider all comments received by the closing date and may amend 
this final rule because of those comments.
    Except for Confidential Business Information (CBI) as described in 
the following paragraph, and other information as described in 14 CFR 
11.35, the FAA will post all comments received, without change, to 
<a href="https://www.regulations.gov">https://www.regulations.gov</a>, including any personal information you 
provide. The agency will also post a report summarizing each 
substantive verbal contact received about this final rule.

Confidential Business Information

    CBI is commercial or financial information that is both customarily 
and actually treated as private by its owner. Under the Freedom of 
Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public 
disclosure. If your comments responsive to this AD contain commercial 
or financial information that is customarily treated as private, that 
you actually treat as private, and that is relevant or responsive to 
this AD,

[[Page 26372]]

it is important that you clearly designate the submitted comments as 
CBI. Please mark each page of your submission containing CBI as 
``PROPIN.'' The FAA will treat such marked submissions as confidential 
under the FOIA, and they will not be placed in the public docket of 
this AD. Submissions containing CBI should be sent to Fred Caplan, 
Aerospace Engineer, Airframe Section, FAA, Atlanta ACO Branch, 1701 
Columbia Avenue, College Park, GA 30337; phone: 404-474-5507; fax: 404-
474-5606; email: <a href="/cdn-cgi/l/email-protection#3b7d495e5f5e49525850157515785a4b575a557b5d5a5a155c544d"><span class="__cf_email__" data-cfemail="f3b581969796819a9098ddbdddb092839f929db3959292dd949c85">[email&#160;protected]</span></a>. Any commentary that the 
FAA receives that is not specifically designated as CBI will be placed 
in the public docket for this rulemaking.

Regulatory Flexibility Act

    The requirements of the Regulatory Flexibility Act (RFA) do not 
apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt 
a rule without prior notice and comment. Because the FAA has determined 
that it has good cause to adopt this rule without notice and comment, 
RFA analysis is not required.

Costs of Compliance

    The FAA estimates that this AD affects 20 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.
                Action                         Labor cost           Parts cost        product        operators
----------------------------------------------------------------------------------------------------------------
Inspection, torque check, and retorque  40 work-hours x $85 per               $0          $3,400         $68,000
                                         hour = $3,400.
----------------------------------------------------------------------------------------------------------------

    The FAA estimates the following costs to do any necessary 
replacements that would be required based on the results of the 
inspection. The FAA has no way of determining the number of aircraft 
that might need these replacements:

                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------
            Action                    Labor cost                 Parts cost                Cost per product
----------------------------------------------------------------------------------------------------------------
Replacement...................  Up to 120 work-hours x  Up to $100.................  Up to $10,300.
                                 $85 per hour = Up to
                                 $10,200.
----------------------------------------------------------------------------------------------------------------

    The FAA has received no definitive data on which to base the cost 
estimates for the on-condition repairs specified in 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.
    The FAA is 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:
    Is not a ``significant regulatory action'' under Executive Order 
12866.

with the Accomplishment Instructions of Lockheed Martin Aeronautics 
Company Alert Service Bulletin A382-57-99, Revision 1, dated 
February 17, 2021. If any cracking is found during the inspection, 
repair before further flight using a method approved in accordance

fastener before further flight, in accordance with the 
Accomplishment Instructions of Lockheed Martin Aeronautics Company 
Alert Service Bulletin A382-57-99, Revision 1, dated February 17, 
2021. If any sheared, broken, or missing fastener is found during 
the torque check, replace the fastener before further flight.
