According to 7 CFR 3550.58(b), a leasehold interest must have an unexpired term that is at least 150 percent of the term of the mortgage for Direct loans. According to 7 CFR 3555.203(b)(3), a leasehold interest must have an unexpired term of at least 45 years from the date of loan closing for a Guaranteed loan. Eligibility Requirements Under this pilot, RD will accept a lease with an unexpired term that is at least two years beyond the term of the promissory note in the pilot states. The following States are included in this pilot: California, Michigan, Minnesota, New Hampshire, Oregon, Pennsylvania, Vermont, and Wisconsin. The loan request must be from an eligible applicant, all the pilot conditions must be met, and new manufactured and modular homes must meet the following pilot conditions: At a minimum, new manufactured and modular homes must be Energy Star compliant. Additionally, the unexpired term of the lease must be at least two years longer than the mortgage term. While the lease terms in 7 CFR 3550.58(b) and 3555.203(b)(3) offer borrowers some protections, many states have statutes that promulgate fair lease terms and safeguard residents of landlease communities. For the SFH Guaranteed Loan Program, pilot states should consider following the recommendations in HUD’s interim guidance related to 24 CFR 3285.312 on the use of frost-free foundations or frost protected shallow foundations. For the SFH Direct Loan Program, pilot states may use the recommendations from HUD’s interim guidance on frost-free or frost-protected shallow foundations in lieu of RD Instruction 1924–A, Exhibit J. Under the HUD interim guidance recommendations, the installer should VerDate Sep<11>2014 16:13 Oct 10, 2024 Jkt 265001 install all footings and piers below the frost line depth, or for Frost Free Foundations, have a site investigation performed by a soil engineer or geotechnical engineer to verify if the soil condition at each home site is of a non-frost susceptible classification and is well drained. In lieu of a site soil investigation, a layer of washed gravel, or crushed stone, or course or dense sand may be provided to the frost line depth. For either of these alternatives, subsurface drains need to be provided; or use a Frost Protected Shallow Foundation system that utilizes below ground insulation to protect the soil from freezing with subsurface drains provided at each site. The applicant and property must meet all other criteria set forth in 7 CFR part 3550 and HB–1–3550 for Direct loans or 7 CFR part 3555 and HB–1–3555 for Guaranteed loans, as applicable for application guidance. Program Directors should use the tracking tool under the ‘‘Energy Efficient Housing’’ link on the SFH SharePoint tracking site to report loans made under this pilot. Paperwork Reduction Act The regulatory waivers for this pilot contains no new reporting or recordkeeping burdens under OMB control number 0575–0179 that would require approval under the Paperwork Reduction Act of 1995 (44 U.S.C. chapter 35).

Accordingly, the FAA is issuing this AD to address the unsafe condition on these products. Except for minor editorial changes, this AD is adopted as proposed in the NPRM. None of the changes will increase the economic burden on any operator. The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain The Boeing Company Model 747–100, 747–100B, 747–100B SUD, 747–200B, 747–200C, 747–200F, 747–300, 747–400, 747–400D, 747– 400F, 747SP, and 747SR series airplanes. The NPRM published in the Federal Register on July 3, 2024 (89 FR 55128). The NPRM was prompted a report indicating cracks at eight fastener hole locations in the fuselage skin lap splice between STAs 1450 and 1470 at stringers S–23L and S–23R. In the NPRM, the FAA proposed to require repetitive inspections of the upper fastener row of the fuselage skin lap splice in a certain area for any crack, and applicable on-condition actions. The FAA is issuing this AD to detect and correct cracking of the upper fastener row of the fuselage skin lap splice between STAs 1350 and 1480 at stringers S–23L and S–23R. The unsafe condition, if not addressed, could result in an in-flight rapid decompression and a loss of structural integrity of the fuselage. Discussion of Final Airworthiness Directive Material Incorporated by Reference Under 1 CFR Part 51 The FAA reviewed Boeing Alert Requirements Bulletin 747–53A2912 RB, dated April 5, 2024. This material specifies procedures for repetitive external surface high frequency eddy current inspections of the upper fastener row of the fuselage skin lap splice between STAs 1350 and 1480 at stringers S–23L and S–23R for any crack, and applicable on-condition actions. On-condition actions include obtaining and following repair instructions. This material 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 Comments The FAA received a comment from Boeing who supported the NPRM without change. The FAA estimates that this AD affects 170 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: ESTIMATED COSTS Action Labor cost Parts cost Cost per product Inspections ............................. 8 work-hours × $85 per hour = $680 per inspection cycle. $0 $680 per inspection cycle ...... The FAA has received no definitive data on which to base the cost estimates for the on-condition actions specified in this AD. ddrumheller on DSK120RN23PROD with RULES1 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 VerDate Sep<11>2014 16:13 Oct 10, 2024 Jkt 265001 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 PO 00000 Frm 00035 Fmt 4700 Sfmt 4700 Cost on U.S. operators $115,600 per inspection cycle. 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) Will not affect intrastate aviation in Alaska, 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.

SUPPLEMENTARY INFORMATION:

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to certain The Boeing 
Company Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-
200F, 747-300, 747-400, 747-400D, 747-400F, 747SP, and 747SR series 
airplanes. The NPRM published in the Federal Register on July 3, 2024 
(89 FR 55128). The NPRM was prompted a report indicating cracks at 
eight fastener hole locations in the fuselage skin lap splice between 
STAs 1450 and 1470 at stringers S-23L and S-23R.
    In the NPRM, the FAA proposed to require repetitive inspections of 
the upper fastener row of the fuselage skin lap splice in a certain 
area for any crack, and applicable on-condition actions. The FAA is 
issuing this AD to detect and correct cracking of the upper fastener 
row of the fuselage skin lap splice between STAs 1350 and 1480 at 
stringers S-23L and S-23R. The unsafe condition, if not addressed, 
could result in an in-flight rapid decompression and a loss of 
structural integrity of the fuselage.

Discussion of Final Airworthiness Directive

Comments

    The FAA received a comment from Boeing who supported the NPRM 
without change.

Conclusion

    The FAA reviewed the relevant data, considered the comment 
received, and determined that air safety requires adopting this AD as 
proposed. Accordingly, the FAA is issuing this AD to address the unsafe 
condition on these products. Except for minor editorial changes, this 
AD is adopted as proposed in the NPRM. None of the changes will 
increase the economic burden on any operator.

Material Incorporated by Reference Under 1 CFR Part 51

    The FAA reviewed Boeing Alert Requirements Bulletin 747-53A2912 RB, 
dated April 5, 2024. This material specifies procedures for repetitive 
external surface high frequency eddy current inspections of the upper 
fastener row of the fuselage skin lap splice between STAs 1350 and 1480 
at stringers S-23L and S-23R for any crack, and applicable on-condition 
actions. On-condition actions include obtaining and following repair 
instructions.
    This material 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

    The FAA estimates that this AD affects 170 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

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

    The FAA has received no definitive data on which to base the cost 
estimates for the on-condition actions 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.
