SUPPLEMENTARY INFORMATION: Background The FAA has received a report indicating a quality audit found aft fuselage sloping longerons manufactured with an overaged condition (i.e., understrength). The FAA determined this occurred because the longerons were not properly checked for conductivity and hardness during manufacturing and consequently were exposed to excessive hot forming temperatures, which reduced the material strength properties of the longeron. An aft fuselage sloping longeron manufactured with an overaged condition would reduce the static strength of the longeron below limit load (i.e., maximum load to be expected in service). If both aft fuselage sloping longerons are understrength, the structural integrity of the airplane would be reduced below limit load, which could lead to failure of both longerons. This condition, if not addressed, could result in loss 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 A382–53–69, dated April 12, 2023, for 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, 282– 44A–05 (C–130B), C–130B, and C–130H airplanes. This service information specifies procedures for reviewing the airplane maintenance records to determine if the left or right aft fuselage sloping longeron, having part number (P/N) 342986–( ), has been replaced on or after December 31, 2012, and applicable on-condition actions. The onconditions actions include doing a conductivity check on any replaced longeron or any longeron for which it cannot be conclusively determined that it has not been replaced; and doing a Rockwell hardness test if the conductivity measurements exceed certain values specified in the service information. PO 00000 Frm 00021 Fmt 4700 Sfmt 4700 41309 The FAA reviewed Lockheed Martin Aeronautics Company Alert Service Bulletin A382J–53–004, dated March 27, 2023, for Lockheed Model 382J airplanes. This service information specifies procedures for doing a conductivity check on any aft fuselage sloping longeron having P/N 342986– 13/–14/–19/–20 and applicable oncondition action. The on-condition action includes doing a Rockwell hardness test if the conductivity measurements exceed certain values specified in the service information. 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.’’ This AD also limits the installation of aft fuselage sloping longerons under certain conditions. Difference Between This AD and the Service Information The effectivity of Lockheed Martin Aeronautics Company Alert Service Bulletin A382J–53–004, dated March 27, 2023, is limited to Model 382J airplanes, serial numbers 5854, 5889, 5894, and 5956. However, the applicability of this AD includes all Model 382J airplanes. Because the affected aft fuselage sloping longerons are rotable parts, the FAA has determined that these parts could later be installed on airplanes that were initially delivered with acceptable longerons, thereby subjecting those airplanes to the unsafe condition. Operators should note that, although the Accomplishment Instructions of the referenced service information describe procedures for submitting all conductivity and hardness inspection results to Lockheed to determine further action, the service information does not specify a corrective action. This AD does not require reporting inspection results. Instead this AD requires, depending on the conductivity and hardness test results, repairing using a method approved by the Manager, East Certification Branch, FAA. 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 E:\FR\FM\26JNR1.SGM 26JNR1 41310 Federal Register / Vol. 88, No. 121 / Monday, June 26, 2023 / Rules and Regulations 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 numerous understrength aft fuselage sloping longerons have been found on military airplanes of the same type design, and it is likely that understrength longerons are also installed on in-service airplanes. The possibility of both longerons being understrength violates fail-safe design. If both aft fuselage sloping longerons are understrength, the structural integrity of the airplane would be reduced below limit load, which could lead to failure of both longerons. The unsafe condition, if not addressed, could result in loss of the airplane. Also, 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–2023–1209 and Project Identifier AD–2023–00632– 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, Aviation Safety Engineer, FAA, 1701 Columbia Avenue, College Park, GA 30337; phone: 404–474–5507; email: 9-ASO-ATLACOADs@faa.gov. 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 40 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: ESTIMATED COSTS Action Labor cost Records Review (36 airplanes) ...................... Conductivity Check (4 Model 382J airplanes) 1 work-hours × $85 per hour = $85 ............... 10 work-hour × $85 per hour = $850 ............. ddrumheller on DSK120RN23PROD with RULES1 The FAA estimates the following costs to do any necessary on-condition actions that would be required based on Cost per product Parts cost the results of the applicable records review or conductivity check.

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.

SUPPLEMENTARY INFORMATION:

Background

    The FAA has received a report indicating a quality audit found aft 
fuselage sloping longerons manufactured with an overaged condition 
(i.e., understrength). The FAA determined this occurred because the 
longerons were not properly checked for conductivity and hardness 
during manufacturing and consequently were exposed to excessive hot 
forming temperatures, which reduced the material strength properties of 
the longeron. An aft fuselage sloping longeron manufactured with an 
overaged condition would reduce the static strength of the longeron 
below limit load (i.e., maximum load to be expected in service). If 
both aft fuselage sloping longerons are understrength, the structural 
integrity of the airplane would be reduced below limit load, which 
could lead to failure of both longerons. This condition, if not 
addressed, could result in loss 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 A382-53-69, dated April 12, 2023, for 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, 282-44A-05 (C-130B), C-130B, and C-130H airplanes. This service 
information specifies procedures for reviewing the airplane maintenance 
records to determine if the left or right aft fuselage sloping 
longeron, having part number (P/N) 342986-( ), has been replaced on or 
after December 31, 2012, and applicable on-condition actions. The on-
conditions actions include doing a conductivity check on any replaced 
longeron or any longeron for which it cannot be conclusively determined 
that it has not been replaced; and doing a Rockwell hardness test if 
the conductivity measurements exceed certain values specified in the 
service information.
    The FAA reviewed Lockheed Martin Aeronautics Company Alert Service 
Bulletin A382J-53-004, dated March 27, 2023, for Lockheed Model 382J 
airplanes. This service information specifies procedures for doing a 
conductivity check on any aft fuselage sloping longeron having P/N 
342986-13/-14/-19/-20 and applicable on-condition action. The on-
condition action includes doing a Rockwell hardness test if the 
conductivity measurements exceed certain values specified in the 
service information.
    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.'' This AD also limits the 
installation of aft fuselage sloping longerons under certain 
conditions.

Difference Between This AD and the Service Information

    The effectivity of Lockheed Martin Aeronautics Company Alert 
Service Bulletin A382J-53-004, dated March 27, 2023, is limited to 
Model 382J airplanes, serial numbers 5854, 5889, 5894, and 5956. 
However, the applicability of this AD includes all Model 382J 
airplanes. Because the affected aft fuselage sloping longerons are 
rotable parts, the FAA has determined that these parts could later be 
installed on airplanes that were initially delivered with acceptable 
longerons, thereby subjecting those airplanes to the unsafe condition.
    Operators should note that, although the Accomplishment 
Instructions of the referenced service information describe procedures 
for submitting all conductivity and hardness inspection results to 
Lockheed to determine further action, the service information does not 
specify a corrective action. This AD does not require reporting 
inspection results. Instead this AD requires, depending on the 
conductivity and hardness test results, repairing using a method 
approved by the Manager, East Certification Branch, FAA.

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

[[Page 41310]]

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 numerous understrength aft fuselage sloping longerons have been 
found on military airplanes of the same type design, and it is likely 
that understrength longerons are also installed on in-service 
airplanes. The possibility of both longerons being understrength 
violates fail-safe design. If both aft fuselage sloping longerons are 
understrength, the structural integrity of the airplane would be 
reduced below limit load, which could lead to failure of both 
longerons. The unsafe condition, if not addressed, could result in loss 
of the airplane. Also, 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-2023-1209 and Project Identifier AD-
2023-00632-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, Aviation Safety Engineer, 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 40 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 on-
condition actions that would be required based on the results of the 
applicable records review or conductivity check. The FAA has no way of 
determining the number of aircraft that might need on-condition 
actions:

    The FAA has received no definitive data on which to base the cost 
estimates for the on-condition repair 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:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866, and
    (2) Will not affect intrastate aviation in Alaska.

(e) Unsafe Condition

    This AD was prompted by a report indicating a quality audit 
found aft fuselage sloping longerons manufactured with an overaged 
condition (i.e., understrength). The FAA is issuing this AD to 
address the possibility of both aft sloping longerons being 
understrength, which would reduce the structural integrity of the 
airplane below limit load (i.e., maximum load to be expected in 
service) and could lead to failure of both longerons. The unsafe 
condition, if not addressed, could result in loss of the airplane.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Records Review for All Airplanes Except Model 382J Airplanes

    For all airplanes except Model 382J airplanes: Within 35 days 
after the effective date of this AD, review the airplane maintenance 
records to determine if the left or right aft fuselage sloping 
longeron, having part number (P/N) 342986-( ), has been replaced on 
or after December 31, 2012.

(h) Conductivity Check for All Airplanes Except Model 382J Airplanes

    If, during the airplane maintenance records review required by 
paragraph (g) of this AD, it is determined that the left or right 
aft fuselage sloping longeron, having P/N 342986-( ), has been 
replaced on or after December 31, 2012, or it cannot be conclusively 
determined that the part has not been replaced, before further
