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 January 9, 2012 (77 FR 1043). That NPRM proposed to require removing and inspecting certain LPT2 rotor blades. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM. E:\FR\FM\27AUR1.SGM 27AUR1 51696 Federal Register / Vol. 77, No. 166 / Monday, August 27, 2012 / Rules and Regulations Conclusion We reviewed the relevant data and determined that air safety and the public interest require adopting the AD as proposed. Costs of Compliance We estimate that this AD will affect 3,000 engines installed on airplanes of U.S. registry. We also estimate that it will take about 1 work-hour per engine to perform the record review, and that the average labor rate is $85 per workhour. For an estimated 500 engines with discrepant blades, blade rework cost was estimated at $2,380 per engine with a replacement parts cost about $1,100 per engine. Based on these figures, we estimate the total cost of the AD to U.S. operators to be $1,430,100. Authority for This Rulemaking pmangrum on DSK3VPTVN1PROD with RULES 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 14:47 Aug 24, 2012 Jkt 226001 List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

AGENCY: ACTION: The Federal Trade Commission (the ‘‘Commission’’ or ‘‘FTC’’) is amending its Telemarketing Sales Rule (‘‘TSR’’) by updating the fees charged to entities accessing the National Do Not Call Registry (the ‘‘Registry’’) as required by the Do-NotCall Registry Fee Extension Act of 2007. DATES: Effective Date: The revised fees will become effective October 1, 2012. ADDRESSES: Requests for copies of this document should be sent to: Public Reference Branch, Federal Trade Commission, Room 130, 600 Pennsylvania Avenue NW., Washington, DC 20580. Copies of this document are also available on the Internet at the Commission’s Web site: https://www.ftc. gov. FOR FURTHER INFORMATION CONTACT: Ami Joy Dziekan, (202) 326–2648, BCP, Federal Trade Commission, 600 Pennsylvania Avenue NW., Room H– 246, Washington, DC 20580. SUPPLEMENTARY INFORMATION: To comply with the Do-Not-Call Registry Fee Extension Act of 2007 (Pub. L. 110–188, 122 Stat. 635) (‘‘Act’’), the Commission is amending the TSR by updating the fees entities are charged for accessing the Registry as follows: the revised rule increases the annual fee for access to the Registry for each area code of data from $56 to $58 per area code; increases the fee per area code of data during the second six months of an entity’s annual subscription period from $28 to $29; and increases the maximum amount that will be charged to any single entity for accessing area codes of data from $15,503 to $15,962. These increases are in accordance with the Act, which specifies that beginning after fiscal year 2009, the dollar amounts charged shall be increased by an amount equal to the amounts specified in the Act, multiplied by the percentage (if any) by which the average of the monthly consumer price pmangrum on DSK3VPTVN1PROD with RULES SUMMARY: VerDate Mar<15>2010 14:47 Aug 24, 2012 Jkt 226001 index (for all urban consumers published by the Department of Labor) (‘‘CPI’’) for the most recently ended 12month period ending on June 30 exceeds the CPI for the 12-month period ending June 30, 2008. The Act also states that any increase shall be rounded to the nearest dollar and that there shall be no increase in the dollar amounts if the change in the CPI is less than one percent. For fiscal year 2009, the Act specified that the original annual fee for access to the Registry for each area code of data was $54 per area code, or $27 per area code of data during the second six months of an entity’s annual subscription period, and that the maximum amount that would be charged to any single entity for accessing area codes of data would be $14,850. The determination whether a fee change is required and the amount of the fee change involves a two-step process. First, to determine whether a fee change is required, we measure the change in the CPI from the time of the previous increase in fees. There was an increase in the fees for fiscal year 2012. Accordingly, we calculated the change in the CPI since last year, and the increase was 2.93 percent. Because this change is over the one percent threshold, the fees will change for fiscal year 2013. Second, to determine how much the fees should increase this fiscal year, we use the calculation specified by the Act set forth above, the percentage change in the baseline CPI applied to the original fees for fiscal year 2009. The average value of the CPI for July 1, 2007 to June 30, 2008 was 211.702; the average value for July 1, 2011 to June 30, 2012 was 227.565, an increase of 7.49 percent. Applying the 7.49 percent increase to the base amount from fiscal year 2009, leads to an increase from $56 to $58 in the fee from last year for access to a single area code of data for a full year for fiscal year 2013. The actual amount is $58.04, but when rounded, pursuant to the Act, the amount is $58. The fee for accessing an additional area code for a half year increases to $29.02 (rounded to $29). The maximum amount charged increases to $15,962.26 (rounded to $15,962). Administrative Procedure Act; Regulatory Flexibility Act; Paperwork Reduction Act. The revisions to the Fee Rule are technical in nature and merely incorporate statutory changes to the TSR. These statutory changes have been adopted without change or interpretation, making public comment unnecessary. Therefore, the Commission has determined that the notice and comment requirements of the PO 00000 Frm 00017 Fmt 4700 Sfmt 4700 51697 Administrative Procedure Act do not apply. See 5 U.S.C. 553(b). For this reason, the requirements of the Regulatory Flexibility Act also do not apply. See 5 U.S.C. 603, 604. Pursuant to the Paperwork Reduction Act, 44 U.S.C. 3501–3521, the Office of Management and Budget (‘‘OMB’’) approved the information collection requirements in the Amended TSR and assigned the following existing OMB Control Number: 3084–0097. The amendments outlined in this Final Rule pertain only to the fee provision (§ 310.8) of the Amended TSR and will not establish or alter any record keeping, reporting, or third-party disclosure requirements elsewhere in the Amended TSR.

Accordingly, the Federal Trade Commission amends part 310 of title 16 of the Code of Federal Regulations as follows: PART 310—TELEMARKETING SALES RULE 1. The authority citation for part 310 continues to read as follows: ■ Authority: 15 U.S.C. 6101–6108; 15 U.S.C. 6151–6155. 2.

Airworthiness Directives; Honeywell International Inc. Turbofan 
Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Honeywell International Inc. TFE731-20R, -20AR, -20BR, -40, -40AR, -
40R, -50R, and -60 turbofan engines. This AD was prompted by a report 
of a quality escape of about 8,000 2nd stage low-pressure turbine 
(LPT2) rotor blades, manufactured by Honeywell Chihuahua Manufacturing 
Operation since 2009. This AD requires removing and inspecting certain 
LPT2 rotor blades. We are issuing this AD to correct an unsafe 
condition caused by these blades installed on these engines.

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 January 9, 2012 (77 FR 
1043). That NPRM proposed to require removing and inspecting certain 
LPT2 rotor blades.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM.

[[Page 51696]]

Conclusion

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

Costs of Compliance

    We estimate that this AD will affect 3,000 engines installed on 
airplanes of U.S. registry. We also estimate that it will take about 1 
work-hour per engine to perform the record review, and that the average 
labor rate is $85 per work-hour. For an estimated 500 engines with 
discrepant blades, blade rework cost was estimated at $2,380 per engine 
with a replacement parts cost about $1,100 per engine. Based on these 
figures, we estimate the total cost of the AD to U.S. operators to be 
$1,430,100.

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.

    This AD was prompted by a report of a quality escape of about 
8,000 LPT2 rotor blades, manufactured by Honeywell Chihuahua 
Manufacturing Operation since 2009. During LPT rotor acceleration, 
these blades may contact and damage the 3rd stage LPT (LPT3) nozzle 
seal carrier that may subsequently fatigue and contact the adjacent 
rotor and damage the rotor. Also, these blades could deform the 
blade retainers, which could lead to blade movement that may cause 
rotor damage. We are issuing this AD to correct the unsafe condition 
caused by these blades installed on these engines.

(e) Compliance

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

(f) Remove LPT2 Rotor Blades

    (1) At the next major periodic inspection, not to exceed 3,000 
hours time-since-new, or within 5 years after the effective date of 
this AD, or at the next access, whichever occurs first, do the 
following using Section 3.0, Accomplishment Instructions, of 
Honeywell SB TFE731-72-5221, Revision 0, dated November 11, 2010:
    (i) Remove any suspect LPT2 rotor blades from service.
    (ii) Inspect suspect LPT2 rotor blades.

(g) Alternative Methods of Compliance (AMOCs)

    The Manager, Los Angeles Certification Office, FAA, may approve 
AMOCs to this AD. Use the procedures found in 14 CFR 39.19 to make 
your request.

(h) Definition

    For purposes of this AD, next access is defined as when the LPT 
module is disassembled.
