[FR Doc. 2012–23434 Filed 9–21–12; 8:45 am] BILLING CODE 4910–13–P DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2012–1016; Directorate Identifier 2010–SW–009–AD] RIN 2120–AA64 Airworthiness Directives; Bell Helicopter Textron, Inc. Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to adopt a new airworthiness directive (AD) for Bell Helicopter Textron, Inc. (Bell), Model 412 and 412EP helicopters. This proposed AD is prompted by reports of cracking in the swashplate outer ring assemblies (outer ring). This AD would establish a lower life limit on certain outer rings, requiring a revision of the retirement life on the components’ history card or equivalent record, and a revision of the maintenance manual or Instructions for Continued Airworthiness (ICA). This proposal also would prohibit installing these outer rings on any helicopter. The proposed actions are intended to prevent failure of an outer ring because of cracking, which could lead to the loss of main rotor (M/R) blade pitch control and subsequent loss of helicopter control. DATES: We must receive comments on this proposed AD by November 23, 2012.

We may change this E:\FR\FM\24SEP1.SGM 24SEP1 Federal Register / Vol. 77, No. 185 / Monday, September 24, 2012 / Proposed Rules proposal in light of the comments we receive. Discussion This proposal is prompted by a report of fatigue cracking in the outer ring, part number (P/N) 412–010–407–105. The outer ring previously had a life limit of 10,000 hours TIS, but Bell has recommended reducing the outer ring retirement life to 2,500 hours TIS. Cracking in the outer ring can lead to loss of cyclic and collective pitch control of the main rotor blades and loss of helicopter control. FAA’s Determination We are proposing this AD because we evaluated all known relevant information and determined that an unsafe condition exists and is likely to exist or develop on other products of these same type designs. Related Service Information We have reviewed Bell Helicopter Alert Service Bulletin No. 412–08–131, Revision B, dated October 29, 2009 (ASB), which describes procedures for establishing a new retirement life for the outer ring and replacing the outer ring at 2,500 hours TIS. Proposed AD Requirements This proposed AD would require the following: • Within 30 days, establish a new retirement life of 2,500 hours TIS for outer ring P/N 412–010–407–105, and record this on the component history card or equivalent record. Within the same time period, make pen-and-ink changes or insert a copy of the AD into the Airworthiness Limitations section of the applicable maintenance manual or ICA. • Within 300 hours TIS, for any affected outer ring that has 2,200 or more hours TIS on the effective date of the proposed AD, replace the outer ring with an airworthy outer ring. • Within 12 months, for any affected outer ring, regardless of the number of hours TIS, replace the outer ring with an airworthy outer ring. The installation of outer ring, P/N 412–010–407–105, would be prohibited on any helicopter. emcdonald on DSK67QTVN1PROD with PROPOSALS Differences Between this Proposed AD and the Service Information The ASB sets a calendar date for compliance. This proposed AD does not. Costs of Compliance We estimate that this proposed AD would affect 143 helicopters. We estimate that it would take about one work-hour to revise the component VerDate Mar<15>2010 12:31 Sep 21, 2012 Jkt 226001 history card or equivalent record, as well as the maintenance manual or ICA, at an average labor rate of $85 per work hour, for a total cost of $85 per helicopter and $12,155 for the U.S. operator fleet. Replacing an outer ring would take 26 work-hours and required parts would cost an estimated $25,725. Based on these figures, we calculate the total cost to be $27,935 per helicopter to replace an outer ring. 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 We determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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, I certify this proposed regulation: 1. Is not a ‘‘significant regulatory action’’ under Executive Order 12866; 2. Is not a ‘‘significant rule’’ under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); 3. Will not affect intrastate aviation in Alaska to the extent that it justifies making a regulatory distinction; 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. We prepared an economic evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket.

Jones at (202) 622–6070; concerning submissions of comments and requests for a public hearing, Oluwafunmilayo Taylor, (202) 622–7180 (not toll-free numbers). SUPPLEMENTARY INFORMATION: Background To avoid certain excise taxes under chapter 42, private foundations must make a minimum level of qualifying distributions (as defined in section 4942 of the Internal Revenue Code) each year and must avoid making taxable expenditures (as defined in section 4945). Grants for charitable purposes to certain foreign organizations generally may be treated as qualifying distributions under section 4942 if the private foundation makes a good faith determination that the foreign organization is an organization described in sections 501(c)(3) and 509(a)(1), (a)(2), or (a)(3) (‘‘public charity’’) that is not a supporting organization described in section 4942(g)(4)(A)(i) or (g)(4)(A)(ii) (‘‘disqualified supporting organization’’) or is an organization described in sections 501(c)(3) and 4942(j)(3) (‘‘private operating foundation’’). Similarly, grants for charitable purposes to certain foreign organizations may be treated as other than taxable expenditures under section 4945 if the private foundation makes a good faith determination that the foreign organization is a public charity (other than a disqualified supporting organization) or an organization described in sections 501(c)(3) and 4940(d)(2) (‘‘exempt operating foundation’’). PO 00000 Frm 00015 Fmt 4702 Sfmt 4702 Qualifying Distributions Under Section 4942 Section 4942 generally requires a private foundation (other than a private operating foundation) to make ‘‘qualifying distributions’’ equal to or exceeding a minimum ‘‘distributable amount’’ for each taxable year. If a private foundation has not distributed the full distributable amount by the end of the succeeding taxable year, section 4942 imposes an excise tax on the undistributed portion. A private foundation’s distributable amount for any taxable year generally equals five percent of the aggregate fair market value of its non-exempt-use assets, increased by any repayments of amounts treated as qualifying distributions in prior years, and reduced by any taxes imposed under subtitle A and section 4940. Section 4942(g) generally defines a ‘‘qualifying distribution’’ as any expenditure or grant, including program-related investments and certain set-asides of income, paid to accomplish one or more purposes described in section 170(c)(2)(B) (‘‘charitable purposes’’). Under section 4942(g)(1)(A), however, grants to organizations controlled, directly or indirectly, by the foundation or one or more of its disqualified persons are not qualifying distributions unless the grant is redistributed for charitable purposes within the period specified in section 4942(g)(3). Similarly, grants to other private foundations (except private operating foundations), are not qualifying distributions. In addition, in 2006, the Pension Protection Act of 2006, Public Law No. 109–208, 120 Stat. 780 (2006) (‘‘PPA’’), added section 4942(g)(4), which provides that a qualifying distribution does not include any amount paid to a disqualified supporting organization. Section 53.4942(a)–3(a)(6), however, has not been amended to reflect this statutory change. For purposes of section 4942, a grant for charitable purposes to a foreign organization that does not have a determination letter from the IRS may be treated as a qualifying distribution if the grantor private foundation makes a ‘‘good faith determination’’ that the foreign organization is a private operating foundation or a public charity that is not a disqualified supporting organization, provided that the foreign organization is not controlled by the foundation or its disqualified persons. See § 53.4942(a)–3(a)(6). Under § 53.4942(a)–3(a)(6), a private foundation will ordinarily be considered to have made a ‘‘good faith E:\FR\FM\24SEP1.SGM 24SEP1

Airworthiness Directives; Bell Helicopter Textron, Inc.

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
Bell Helicopter Textron, Inc. (Bell), Model 412 and 412EP helicopters. 
This proposed AD is prompted by reports of cracking in the swashplate 
outer ring assemblies (outer ring). This AD would establish a lower 
life limit on certain outer rings, requiring a revision of the 
retirement life on the components' history card or equivalent record, 
and a revision of the maintenance manual or Instructions for Continued 
Airworthiness (ICA). This proposal also would prohibit installing these 
outer rings on any helicopter. The proposed actions are intended to 
prevent failure of an outer ring because of cracking, which could lead 
to the loss of main rotor (M/R) blade pitch control and subsequent loss 
of helicopter control.

DATES: We must receive comments on this proposed AD by November 23, 
2012.

ADDRESSES: You may send comments by any of the following methods:

proposal in light of the comments we receive.

Discussion

    This proposal is prompted by a report of fatigue cracking in the 
outer ring, part number (P/N) 412-010-407-105. The outer ring 
previously had a life limit of 10,000 hours TIS, but Bell has 
recommended reducing the outer ring retirement life to 2,500 hours TIS. 
Cracking in the outer ring can lead to loss of cyclic and collective 
pitch control of the main rotor blades and loss of helicopter control.

FAA's Determination

    We are proposing this AD because we evaluated all known relevant 
information and determined that an unsafe condition exists and is 
likely to exist or develop on other products of these same type 
designs.

Related Service Information

    We have reviewed Bell Helicopter Alert Service Bulletin No. 412-08-
131, Revision B, dated October 29, 2009 (ASB), which describes 
procedures for establishing a new retirement life for the outer ring 
and replacing the outer ring at 2,500 hours TIS.

Proposed AD Requirements

    This proposed AD would require the following:
     Within 30 days, establish a new retirement life of 2,500 
hours TIS for outer ring P/N 412-010-407-105, and record this on the 
component history card or equivalent record. Within the same time 
period, make pen-and-ink changes or insert a copy of the AD into the 
Airworthiness Limitations section of the applicable maintenance manual 
or ICA.
     Within 300 hours TIS, for any affected outer ring that has 
2,200 or more hours TIS on the effective date of the proposed AD, 
replace the outer ring with an airworthy outer ring.
     Within 12 months, for any affected outer ring, regardless 
of the number of hours TIS, replace the outer ring with an airworthy 
outer ring. The installation of outer ring, P/N 412-010-407-105, would 
be prohibited on any helicopter.

Differences Between this Proposed AD and the Service Information

    The ASB sets a calendar date for compliance. This proposed AD does 
not.

Costs of Compliance

    We estimate that this proposed AD would affect 143 helicopters. We 
estimate that it would take about one work-hour to revise the component 
history card or equivalent record, as well as the maintenance manual or 
ICA, at an average labor rate of $85 per work hour, for a total cost of 
$85 per helicopter and $12,155 for the U.S. operator fleet. Replacing 
an outer ring would take 26 work-hours and required parts would cost an 
estimated $25,725. Based on these figures, we calculate the total cost 
to be $27,935 per helicopter to replace an outer ring.

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

    We determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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, I certify this proposed regulation:
    1. Is not a ``significant regulatory action'' under Executive Order 
12866;
    2. Is not a ``significant rule'' under the DOT Regulatory Policies
