rounded to whole dollars for ease of compliance.

The fee trigger being adjusted in this Federal Register notice pursuant to TILA section 103(bb) is used in determining whether a loan is covered by § 1026.32. Such loans have generally been known as ‘‘HOEPA loans.’’ In July 2008, the Board revised Regulation Z to adopt additional protections for ‘‘higher-priced mortgage loans,’’ using its authority under TILA section 129(l)(2), since redesignated as section 129(p)(2). Those revisions define a class of dwelling-secured transactions, described in § 1026.35, using a threshold based on average market rates. The adjustment published today does not affect the triggers adopted in July 2008 by the Board for higher-priced mortgage loans.

On July 9, 2012, the Bureau issued a proposed rule pursuant to, inter alia, section 1431 of the Dodd-Frank Act, which revises the statutory fee trigger for HOEPA loans. The Bureau is mindful of the need to coordinate implementation of this final rule with the effective date of the final rule adopting revisions to the HOEPA fee trigger pursuant to the July 9, 2012 proposal. Accordingly, the adjustment to the fee trigger that is being published today will become effective on January 1, 2013 and will apply for one year, or until final rules the Bureau proposed on July 9, 2012 to implement section 1431 of the Dodd-Frank Act become effective, whichever is earlier. II. Adjustment and Commentary Revision

Effective January 1, 2013, for purposes of determining whether a home mortgage transaction is covered by § 1026.32 (based on the total points and fees payable by the consumer at or before loan closing), a loan is covered if the points and fees exceed the greater of $625 or 8 percent of the total loan amount. Comment 32(a)(1)(ii)–2, which lists the adjustments for each year, is amended to reflect the new dollar threshold amount for 2013.

Under the Administrative Procedure Act, notice and opportunity for public comment are not required if the Bureau finds that notice and public comment are impracticable, unnecessary, or contrary to the public interest. 5 U.S.C. 553(b)(B). Because the timing and method of the adjustment are set bystatute and are technical and nondiscretionary, the Bureau finds that notice and public comment on the change are unnecessary. 5 U.S.C. 553(b)(B).

Because no notice of proposed rulemaking is required, the Regulatory Flexibility Act does not apply. 5 U.S.C. 601(2). In any event, the Bureau certifies that this amendment to Regulation Z will not have a significant economic impact on a substantial number of small entities. The only change is to increase the threshold for transactions requiring HOEPA disclosures and protections to reflect the annual percentage increase in the CPI–U. This change is required by statute. Furthermore, the Bureau believes that the number of small entities that will be required to comply with Regulation Z’s HOEPA protections solely due to this adjustment because they offer ‘‘HOEPA’’ loans is not substantial. In addition, for entities that already offer ‘‘HOEPA’’ loans in which the total points and fees payable by the consumer at or before loan consummation exceed the greater of $400 or 8 percent of the loan amount, whichever is less, the Bureau believes the economic impact to comply with Regulation Z for additional ‘‘HOEPA’’ loans in which the total points and fees payable by the consumer at or before loan consummation exceed the greater of $625 or 8 percent of the loan amount, whichever is less, will not be significant.

**SUPPLEMENTARY INFORMATION :** 

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM published in the Federal Register on June 12, 2012 (77 FR 34881). That NPRM proposed to require measuring the web at STA 320 and, depending on findings, various inspections for cracks and missing fasteners, web and fastener replacement, and related investigative and corrective actions if necessary.

Comments

We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the proposal (77 FR 34881, June 12, 2012), and the FAA’s response to each comment. Support for the NPRM (77 FR 34881, June 12, 2012)

Mr. Caleb Berken stated that the fact that cracks have been seen in five of these airplanes is a little unnerving, but when it is considered that there are only 29 airplanes of this particular series (Model 747–400, –400D, and –400F series airplanes) currently in operation within the United States, these statistics become quite alarming. The commenter stated that he would like to put forth his full support for this proposed rule (77 FR 34881, June 12, 2012) to increase inspection and replacement of compromised parts that have developed within the crown frame web. Request To Provide Credit for Prior Actions

Boeing requested that we allow credit for work done prior to the effective date of the NPRM (77 FR 34881, June 12, 2012) using Boeing Service Bulletin 747–53A2784, dated August 27, 2009. Boeing stated that Boeing Service Bulletin 747–53A2784, Revision 1, dated September 14, 2011 (which is the service information referenced in the NPRM (77 FR 34881, June 12, 2012)), states that ‘‘[n]o more work is necessary on airplanes changed in accordance with the original issue of this service bulletin.’’ Boeing stated that the inspections and corrective actions described in Boeing Service Bulletin 747–53A2784, dated August 27, 2009; and Revision 1, dated September 14, 2011; are structurally equivalent.

We agree to add credit for prior actions because no more work is necessary on airplanes changed in accordance with Boeing Service Bulletin 747–53A2784, dated August 27, 2009. We have added new paragraph (l) to this AD to provide credit for actions required by paragraphs (g) through (j) of this AD, if those actions were performed before the effective date of this AD using Boeing Service Bulletin 747–53A2784,dated August 27, 2009. We have reidentified subsequent paragraphs accordingly. Request To Allow Deviation Authority

Boeing requested that paragraph (1)(3) of the NPRM (77 FR 34881, June 12, 2012) be revised to allow the Boeing Commercial Airplanes Organization Designation Authorization (ODA) to approve alternative methods of compliance (AMOCs) for both repairs and deviations to the modification that are described in either Boeing Service Bulletin 747–53A2784, dated August 27, 2009; or Boeing Service Bulletin 747– 53A2784, Revision 1, dated September 14, 2011. Boeing requested that we clarify that an AMOC can be approved for both repairs and deviations to the modification, and that the modification described in Boeing Service Bulletin 747–53A2784, dated August 27, 2009, satisfies the requirements of the modification described in Boeing Service Bulletin 747–53A2784 Revision 1, dated September 14, 2011.

We partially agree. The Boeing ODA is not currently authorized to provide AMOC approval of deviations that occur when doing the modification. However, once the AD is issued, we might delegate approval authority to certain authorized representatives of the Boeing ODA to approve AMOCs for deviations during this modification. We have not changed the AD in this regard.

Conclusion

We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting the AD with the change described previously— and minor editorial changes. We have determined that these minor changes:

• Are consistent with the intent that was proposed in the NPRM (77 FR 34881, June 12, 2012) for correcting the unsafe condition; and

• Do not add any additional burden upon the public than was already proposed in the NPRM (77 FR 34881, June 12, 2012).

We also determined that these changes will not increase the economic burden on any operator or increase the scope of the AD. Costs of Compliance

We estimate that this AD affects 29 airplanes of U.S. registry.

We estimate the following costs to comply with this AD:



### E STIMATED 

### COSTS

Action Labor cost Parts cost Cost per product Cost on U.S. operators

Measurement .............. 1 work-hour × $85 per hour = $85 ................. $0 ..................... $85 ............................. $2,465.Inspection and web replacement. 208 work-hours × $85 per hour = $17,680 .... Up to $21,887 .. Up to $39,567 ............ Up to $1,147,443.

Post-replacement inspection. 135 work-hours × $85 per hour = $11,475 per inspection cycle. $0 ..................... $11,475 per inspection cycle. $332,775 per inspection cycle.


### 69741 Federal Register / Vol. 77, No. 225 / Wednesday, November 21, 2012 / Rules and Regulations

We have received no definitive data that would enable us to provide cost estimates for the on-condition crack 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.

We are 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,

(2) Is not a ‘‘significant rule’’ under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979),

(3) Will not affect intrastate aviation in Alaska, and

(4) 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 :** 

Discussion

We issued a supplemental notice of proposed rulemaking (SNPRM) to amend 14 CFR part 39 to include an airworthiness directive (AD) that would apply to the specified products. That SNPRM published in the Federal Register on August 23, 2012 (77 FR 50954). The original NPRM (75 FR 66700, October 29, 2010) proposed to require a complete inspection of the flap system and modification of the flap control system. The SNPRM (77 FR 50954, August 23, 2012) proposed to incorporate additional service information that addresses proper rigging procedures and corrective actions following additional inspection procedures.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the SNPRM (77 FR 50954, August 23, 2012) or on the determination of the cost to the public.

Conclusion

We reviewed the relevant data and determined that air safety and the public interest require adopting the AD
