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
<a href="http://regulations.gov">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, 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: <a href="/cdn-cgi/l/email-protection#e4ddc9a5b7abc9a5b0a8a5a7abc9a5a097a4828585ca838b92"><span class="__cf_email__" data-cfemail="d0e9fd91839ffd91849c91939ffd9194a390b6b1b1feb7bfa6">[email 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 40 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
----------------------------------------------------------------------------------------------------------------
Records Review (36 airplanes)......... 1 work-hours x $85 per $0 $85 $3,060
hour = $85.
Conductivity Check (4 Model 382J 10 work-hour x $85 per 0 850 3,400
airplanes). hour = $850.
----------------------------------------------------------------------------------------------------------------
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:
On-Condition Costs
----------------------------------------------------------------------------------------------------------------
Cost per
Action Labor cost Parts cost product
----------------------------------------------------------------------------------------------------------------
Conductivity Check and Hardness Test.......... 20 work-hour x $85 per hour = $0 $1,700
$85.
Hardness Test (Model 382J airplanes).......... 10 work-hour x $85 per hour = 0 850
$85.
----------------------------------------------------------------------------------------------------------------
[[Page 41311]]
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.
