ACTION: Notice of proposed rulemaking (NPRM). AGENCY: SUMMARY: The FAA proposes to revise an existing airworthiness directive (AD) that applies to certain McDonnell Douglas Model DC–10–10, DC–10–10F, DC–10–15, DC–10–30, DC–10–30F (KC– 10A and KDC–10), DC–10–40, and DC– 10–40F airplanes. The existing AD currently requires installing or replacing with improved parts, as applicable, the bonding straps between the metallic frame of the fillet and the wing leading edge ribs, on both the left and right sides of the airplane. This proposed AD would revise the applicability to clarify the identity of the affected airplanes. This proposed AD results from fuel system reviews conducted by the manufacturer. We are proposing this AD to reduce the potential of ignition sources inside fuel tanks in the event of a severe lightning strike, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.

We will post all comments we receive, without change, to http:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Discussion On July 21, 2006, we issued AD 2006– 16–03, amendment 39–14703 (71 FR 43962, August 3, 2006), for certain McDonnell Douglas Model DC–10–10, DC–10–10F, DC–10–15, DC–10–30, DC– 10–30F (KC–10A and KDC–10), DC–10– 40, and DC–10–40F airplanes. That AD requires installing or replacing with improved parts, as applicable, the bonding straps between the metallic E:\FR\FM\13NOP1.SGM 13NOP1 Federal Register / Vol. 72, No. 218 / Tuesday, November 13, 2007 / Proposed Rules frame of the fillet and the wing leading edge ribs, on both the left and right sides of the airplane. That AD resulted from fuel system reviews conducted by the manufacturer. We issued that AD to reduce the potential of ignition sources inside fuel tanks in the event of a severe lightning strike, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane. Actions Since Existing AD Was Issued The applicability of AD 2006–16–03 does not specifically identify Model MD–10–10F and MD–10–30F airplanes by model name. However, those airplanes (converted from Model DC–10 series airplanes) are identified by manufacturer’s fuselage numbers in the effectivity listing of McDonnell Douglas DC–10 Service Bulletins 53–109, Revision 4, dated October 7, 1992; and 53–111, Revision 3, dated August 24, 1992. And those service bulletins were referenced in the applicability of AD 2006–16–03. We have been informed that Boeing is considering revising the service bulletins to, among other things, update the effectivity to clarify the identity of the affected airplanes. If the service bulletins are revised, we might consider approving each as a general alternative method of compliance for the requirements of AD 2006–16–03. FAA’s Determination and Requirements of the Proposed AD We have evaluated all pertinent information and identified an unsafe condition that is likely to exist or develop on other airplanes of this same type design. For this reason, we are proposing this AD, which would revise AD 2006–16–03 and retain its requirements. This proposed AD would clarify the applicability by specifically identifying McDonnell Douglas Model MD–10–10F and MD–10–30F airplanes (converted from Model DC–10 series airplanes) in addition to the airplane models already identified in the AD. Costs of Compliance There are about 457 airplanes of the affected design in the worldwide fleet. This proposed AD would affect about 280 airplanes of U.S. registry. The actions of this proposed AD would add no additional economic burden to the existing requirements of AD 2006–16– 03. The current costs for this AD are repeated for the convenience of affected operators, as follows: The required actions take between 9 and 17 work hours per airplane, at an average labor rate of $80 per work hour. Required parts cost between $3,720 and $4,169 per airplane. Based on these figures, the estimated cost of the AD is between $4,440 and $5,529 per airplane, or between $1,243,200 and $1,548,120 for the U.S.-registered fleet. 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 have 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 above, I certify that the 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); and 63837 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. We prepared a regulatory evaluation of the estimated costs to comply with this proposed AD and place it in the AD docket. See the ADDRESSES section for a location to examine the regulatory evaluation. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1.

ACTION: SUMMARY: Elsewhere in this issue of the Federal Register, the IRS is issuing temporary regulations concerning information reporting on employerowned life insurance contracts under section 6039I of the Internal Revenue Code (Code). The temporary regulations generally apply to taxpayers that are engaged in a trade or business and that are directly or indirectly a beneficiary of a life insurance contract covering the life of an insured who is an employee of the trade or business on the date the contract is issued. The text of those temporary regulations also serves as the text of these proposed regulations. DATES: Written or electronic comments and requests for a public hearing must be received by January 14, 2008. ADDRESSES: Send submissions to: CC:PA:LPD:PR (REG–115910–07), room 5203, Internal Revenue Service, PO Box 7604, Ben Franklin Station, Washington, DC 20044. Submissions may be handdelivered Monday through Friday between the hours of 8 a.m. and 4 p.m. to CC:PA:LPD:PR (REG–115910–07), Courier’s Desk, Internal Revenue Service, 1111 Constitution Avenue, NW., Washington, DC, or sent via the Federal eRulemaking Portal at http:// www.regulations.gov (IRS REG–115910– 07). FOR FURTHER INFORMATION CONTACT: Concerning the regulations, Linda K. Boyd, 202–622–3970; concerning submissions and requests for a public hearing, contact Kelly Banks, 202–622– 7180 (not toll-free numbers). SUPPLEMENTARY INFORMATION: Background and Explanation of Provisions The Pension Protection Act of 2006, Public Law 109–280, 120 Stat. 780 (2006), added sections 101(j) and 6039I to the Internal Revenue Code concerning employer-owned life insurance contracts. Section 101(j)(1) provides that in the case of an employer-owned life insurance contract, the amount of death benefits excluded from gross income under section 101(a) shall not exceed an amount equal to the sum of the premiums and other amounts paid by the policyholder for the contract. Section 101(j)(2), however, sets forth exceptions to this rule for certain contracts for which notice and consent and other requirements are met. Section 6039I requires information reporting with respect to certain employer-owned life insurance contracts at such time and PO 00000 Frm 00012 Fmt 4702 Sfmt 4702 in such manner as the Secretary shall by regulations prescribe. Temporary regulations in this issue of the Federal Register provide that the Commissioner may prescribe the form and manner of satisfying the reporting requirements imposed by section 6039I. The preamble to the temporary regulations explains the temporary regulations. Special Analyses It has been determined that this proposed regulation is not a significant regulatory action as defined in Executive Order 12866. Therefore, a regulatory assessment is not required. It has also been determined that section 553(b) of the Administrative Procedure Act (5 U.S.C. chapter 5) does not apply to this regulation. The Regulatory Flexibility Act (5 U.S.C. chapter 6) does not apply to this proposed regulation because the regulation does not impose a collection of information on small entities. Even though a substantial number of small businesses may be subject to the requirements of section 6039I, it is anticipated that whatever requirements the Commissioner may prescribe pursuant to this regulation will not impose a ‘‘significant economic impact’’ because the information requested will already be available to taxpayers and the burden of compliance will be minimal. Pursuant to section 7805(f) of the Internal Revenue Code, this Regulation has been submitted to the Chief Counsel for Advocacy of the Small Business Administration for comment on its impact on small business. Comments and Requests for a Public Hearing Before these proposed regulations are adopted as final regulations, consideration will be given to any written (a signed original and eight (8) copies) or electronic comments that are submitted timely to the IRS. The IRS and Treasury Department request comments on the clarity of the proposed rules and how they can be made easier to understand. All comments will be available for public inspection and copying. A public hearing will be scheduled if requested in writing by any person that timely submits written comments. If a public hearing is scheduled, notice of the date, time, and place for the public hearing will be published in the Federal Register. The IRS and Treasury Department are aware that guidance may be needed under section 101(j) and request comments on that provision as well. In particular, comments are requested on the need for guidance concerning (1) E:\FR\FM\13NOP1.SGM 13NOP1

SUMMARY: The FAA proposes to revise an existing airworthiness directive 
(AD) that applies to certain McDonnell Douglas Model DC-10-10, DC-10-
10F, DC-10-15, DC-10-30, DC-10-30F (KC-10A and KDC-10), DC-10-40, and 
DC-10-40F airplanes. The existing AD currently requires installing or 
replacing with improved parts, as applicable, the bonding straps 
between the metallic frame of the fillet and the wing leading edge 
ribs, on both the left and right sides of the airplane. This proposed 
AD would revise the applicability to clarify the identity of the 
affected airplanes. This proposed AD results from fuel system reviews 
conducted by the manufacturer. We are proposing this AD to reduce the 
potential of ignition sources inside fuel tanks in the event of a 
severe lightning strike, which, in combination with flammable fuel 
vapors, could result in fuel tank explosions and consequent loss of the 
airplane.

Discussion

    On July 21, 2006, we issued AD 2006-16-03, amendment 39-14703 (71 
FR 43962, August 3, 2006), for certain McDonnell Douglas Model DC-10-
10, DC-10-10F, DC-10-15, DC-10-30, DC-10-30F (KC-10A and KDC-10), DC-
10-40, and DC-10-40F airplanes. That AD requires installing or 
replacing with improved parts, as applicable, the bonding straps 
between the metallic

[[Page 63837]]

frame of the fillet and the wing leading edge ribs, on both the left 
and right sides of the airplane. That AD resulted from fuel system 
reviews conducted by the manufacturer. We issued that AD to reduce the 
potential of ignition sources inside fuel tanks in the event of a 
severe lightning strike, which, in combination with flammable fuel 
vapors, could result in fuel tank explosions and consequent loss of the 
airplane.

Actions Since Existing AD Was Issued

    The applicability of AD 2006-16-03 does not specifically identify 
Model MD-10-10F and MD-10-30F airplanes by model name. However, those 
airplanes (converted from Model DC-10 series airplanes) are identified 
by manufacturer's fuselage numbers in the effectivity listing of 
McDonnell Douglas DC-10 Service Bulletins 53-109, Revision 4, dated 
October 7, 1992; and 53-111, Revision 3, dated August 24, 1992. And 
those service bulletins were referenced in the applicability of AD 
2006-16-03.
    We have been informed that Boeing is considering revising the 
service bulletins to, among other things, update the effectivity to 
clarify the identity of the affected airplanes. If the service 
bulletins are revised, we might consider approving each as a general 
alternative method of compliance for the requirements of AD 2006-16-03.

FAA's Determination and Requirements of the Proposed AD

    We have evaluated all pertinent information and identified an 
unsafe condition that is likely to exist or develop on other airplanes 
of this same type design. For this reason, we are proposing this AD, 
which would revise AD 2006-16-03 and retain its requirements. This 
proposed AD would clarify the applicability by specifically identifying 
McDonnell Douglas Model MD-10-10F and MD-10-30F airplanes (converted 
from Model DC-10 series airplanes) in addition to the airplane models 
already identified in the AD.

Costs of Compliance

    There are about 457 airplanes of the affected design in the 
worldwide fleet. This proposed AD would affect about 280 airplanes of 
U.S. registry. The actions of this proposed AD would add no additional 
economic burden to the existing requirements of AD 2006-16-03. The 
current costs for this AD are repeated for the convenience of affected 
operators, as follows:
    The required actions take between 9 and 17 work hours per airplane, 
at an average labor rate of $80 per work hour. Required parts cost 
between $3,720 and $4,169 per airplane. Based on these figures, the 
estimated cost of the AD is between $4,440 and $5,529 per airplane, or 
between $1,243,200 and $1,548,120 for the U.S.-registered fleet.

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 have 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 above, I certify that the 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); 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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this proposed AD and place it in the AD docket. See the 
ADDRESSES section for a location to examine the regulatory evaluation.

Unsafe Condition

    (d) This AD results from fuel system reviews conducted by the 
manufacturer. We are issuing this AD to reduce the potential of 
ignition sources inside fuel tanks in the event of a severe 
lightning strike, which, in combination with flammable fuel vapors, 
could result in fuel tank explosions and consequent loss of the 
airplane.

Compliance

    (e) You are responsible for having the actions required by this 
AD performed within the compliance times specified, unless the 
actions have already been done.

Installation or Replacement

    (f) Within 7,500 flight hours or 60 months after September 7, 
2006 (the effective date of AD 2006-16-03), whichever occurs 
earlier: Install or replace with improved parts, as applicable, the 
bonding straps between the metallic frame of the fillet and the wing 
leading edge ribs, on both the left and right sides of the airplane, 
in accordance with the Accomplishment Instructions of the applicable 
service bulletin identified in Table 1 of this AD.

Alternative Methods of Compliance (AMOCs)

    (g)(1) The Manager, Los Angeles Aircraft Certification Office 
(ACO), FAA, has the authority to approve AMOCs for this AD, if 
requested in accordance with the procedures found in 14 CFR 39.19.
    (2) To request a different method of compliance or a different 
compliance time for this AD, follow the procedures in 14 CFR 39.19. 
Before using any approved AMOC on any airplane to which the AMOC 
applies, notify your appropriate principal inspector (PI) in the FAA 
Flight Standards District Office (FSDO), or lacking a PI, your local 
FSDO.
    (3) AMOCs approved previously in accordance with AD 2006-16-03 
are approved as AMOCs for the corresponding provisions of this AD.

    Issued in Renton, Washington, on November 5, 2007.
