SUPPLEMENTARY INFORMATION:

Background

    The FAA issued AD 2019-18-09, Amendment 39-19736 (84 FR 50730, 
September 26, 2019) (AD 2019-18-09), for all Lockheed Martin 
Corporation/Lockheed Martin Aeronautics Company (Lockheed) Model 382, 
382B, 382E, 382F, and 382G airplanes; and Model C-130A, HP-C-130A, EC-
130Q, and C-130B airplanes. AD 2019-18-09 required a visual inspection 
of the center wing upper and lower rainbow fittings for cracks, an eddy 
current inspection of the center wing lower rainbow fittings for 
cracks, and replacement if necessary. AD 2019-18-09 was prompted by 
reports of cracked inner tangs of the center wing lower rainbow 
fittings. The FAA issued AD 2019-18-09 to address such cracks, which 
could result in failure of the center wing lower rainbow fittings, wing 
separation, and loss of the airplane.

Actions Since AD 2019-18-09 Was Issued

    Since the FAA issued AD 2019-18-09, Lockheed Martin Corporation/
Lockheed Martin Aeronautics Company has notified the FAA of cracks 
found on military airplanes of similar type design to the affected 
airplanes of AD 2019-18-09. The FAA reviewed Lockheed's analysis of 
these reported cracks and concurs with Lockheed's finding that 
repetitive inspections are needed for the airplanes identified in AD 
2019-18-09 in order to adequately address cracked inner tangs of the 
center wing lower rainbow fittings. Each tang (node) contains a single 
attachment bolt to the outer wing. If tangs fail, the rainbow fitting 
may not be able to carry limit load and the rainbow fitting may fail. 
This condition, if not addressed, could result in failure of the center 
wing lower rainbow fittings, wing separation, and loss of the airplane.
    Also, since the FAA issued AD 2019-18-09, the FAA has determined 
that Model C-130H airplanes are also affected by this unsafe condition. 
Therefore, that airplane model has been added to applicability in 
paragraph (c)(2)(viii) of this AD.

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 A382-57-98, Revision 2, dated February 14, 2023. This service 
information specifies procedures for repetitive visual inspections of 
the left and right center wing upper and lower rainbow fittings for 
cracks, repetitive eddy current inspections of the center wing lower 
rainbow fittings for cracks, and replacement if necessary.
    This AD also requires Lockheed Martin Aeronautics Company Alert 
Service Bulletin A382-57-98, Revision 1, dated August 16, 2019, which 
the Director of the Federal Register approved for incorporation by 
reference as of October 11, 2019 (84 FR 50730, September 26, 2019).
    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.''

Explanation of Change To Type Certificate Holder Name

    The FAA has revised the reference to the type certificate holder's 
name specified in paragraph (c)(2)(vi) of this AD to identify the type 
certificate holder's name as published in the most recent type 
certificate data sheet for the affected models.

Impact on Intrastate Aviation in Alaska

    In light of the heavy reliance on aviation for intrastate 
transportation in Alaska, the FAA 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

[[Page 31161]]

determined in this case that the requirements are necessary and the 
indirect costs would be outweighed by the safety benefits of the AD.

Differences Between This AD and the Service Information

    Lockheed Martin Aeronautics Company Alert Service Bulletin A382-57-
98, Revision 1, dated August 16, 2019; and Lockheed Martin Aeronautics 
Company Alert Service Bulletin A382-57-98, Revision 2, dated February 
14, 2023; specify that, for certain airplanes, Service Bulletin 382-57-
97, or the results of a Lockheed Martin Operational Usage Evaluation 
(OUE) should be used to determine the number of flight hours on the 
center wing lower rainbow fittings. This AD does not allow the use of 
Service Bulletin 382-57-97 or the OUE to determine the number of flight 
hours because they have not been approved by the FAA. If operators are 
unable to determine the number of flight hours on the center wing lower 
rainbow fittings, they must do the actions required by this AD within 
30 days as specified in paragraphs (h) and (j) of this 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 cracked inner tangs of the center wing lower rainbow fittings 
could result in failure of the center wing lower rainbow fittings, wing 
separation, and loss of the airplane. Further, based upon the age of 
the fleet, it is likely that some airplanes may be beyond the 
thresholds specified in paragraph (i) of this AD. Thus, the compliance 
time for the required action is shorter than the time necessary for the 
public to comment and for publication of the final rule. 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-2023-1044 and Project Identifier 
AD-2023-00593-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 
regulations.gov, 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, 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, East Certification 
Branch, FAA, 1701 Columbia Avenue, College Park, GA 30337; phone: 404-
474-5507; email: [email protected]. 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 36 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

    The FAA estimates the following costs to do any necessary 
replacement 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 this replacement:

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:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866, and
    (2) Will not affect intrastate aviation in Alaska.

98, dated August 9, 2019.

(m) Special Flight Permit

    Special flight permits may be issued in accordance with 14 CFR 
21.197 and 21.199 to operate the airplane to a location where the 
airplane can be modified, provided no more than two tangs (nodes) 
are found cracked during any inspection required by paragraph (g) or 
(i) of this AD.

(n) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Atlanta ACO Branch, FAA, has the authority to 
approve AMOCs for this AD, if requested using the procedures found 
in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request 
to your principal inspector or responsible Flight Standards Office, 
as appropriate. If sending information directly to the manager of 
the certification office, send it to the attention of the person 
identified in paragraph (o)(1) of this AD.
    (2) Before using any approved AMOC, notify your appropriate 
principal inspector, or lacking a principal inspector, the manager 
of the responsible Flight Standards Office.
    (3) An AMOC that provides an acceptable level of safety may be 
used for any repair, modification, or alteration required by this AD 
if it is approved by a Lockheed Martin Corporation/Lockheed Martin 
Aeronautics Company Designated Engineering Representative (DER) that 
has been authorized by the Manager, Atlanta ACO Branch, FAA, to make 
those findings. To be approved, the repair, modification deviation, 
or alteration deviation must meet the certification basis of the 
airplane, and the approval must specifically refer to this AD.
    (4) Required for Compliance (RC): Except as required by 
paragraph (k) of this AD, if any service information contains steps 
that are identified as RC, those steps, including substeps under an 
RC step and any figures identified in an RC step, must be done to 
comply with this AD; any steps that are not identified as RC are 
recommended. Those steps that are not identified as RC may be 
deviated from using accepted methods in accordance with the
