ACTION: Supplemental notice of proposed rulemaking (NPRM); reopening of comment period. AGENCY: SUMMARY: The FAA is revising an earlier NPRM for an 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 original NPRM would have revised an existing AD that 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. The original NPRM proposed to revise the applicability to clarify the identity of the affected airplanes. The original NPRM resulted from fuel system reviews conducted by the manufacturer. This new action proposes to revise the applicability to add and remove certain airplanes, and to add a requirement to reposition or replace two bonding straps for certain airplanes. This new action also proposes to supersede, rather than revise, the existing AD. We are proposing this supplemental NPRM 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. DATES: We must receive comments on this supplemental NPRM by December 22, 2008.

E:\FR\FM\26NOP1.SGM 26NOP1 71958 Federal Register / Vol. 73, No. 229 / Wednesday, November 26, 2008 / Proposed Rules Discussion We proposed to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) with a notice of proposed rulemaking (NPRM) for an AD (the ‘‘original NPRM’’) to revise AD 2006– 16–03, amendment 39–14703 (71 FR 43962, August 3, 2006). The original NPRM applied 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, and MD–10–10F and MD–10–30F airplanes. The affected airplanes are identified by the manufacturer’s fuselage numbers referenced in the applicable McDonnell Douglas DC–10 service bulletin (Service Bulletin 53–109, Revision 4, dated October 7, 1992; or Service Bulletin 53– 111, Revision 3, dated August 24, 1992). The original NPRM was published in the Federal Register on November 13, 2007 (72 FR 63836). The original NPRM proposed to revise AD 2006–16–03 to clarify the identity of the affected airplanes in the applicability. Actions Since Original NPRM Was Issued Since we issued the original NPRM, Boeing has revised the service bulletins. Service Bulletin DC10–53–111, Revision 5, dated March 19, 2008, and DC10–53– 109, Revision 6, dated July 10, 2008, correct effectivity errors (to add and remove certain airplanes incorrectly excluded or included from previous versions). In addition, Service Bulletin DC10–53–109, Revision 5, now includes an action to reposition two bonding straps by using new bonding straps that are less susceptible to cracking. Revision 6 of Service Bulletin DC10–53– 109 provides a faster and easier method, which involves replacing the straps with longer straps instead of relocating them. The revised service bulletins have been approved by the FAA as alternative methods of compliance (AMOCs) with the requirements of AD 2006–16–03. Paragraph (i)(3) has been revised in this supplemental NPRM to include information about these AMOCs. FAA’s Determination and Proposed Requirements of the Supplemental NPRM The changes discussed above expand the scope of the original NPRM; therefore, we have determined that it is necessary to reopen the comment period for revising AD 2006–16–03 to provide additional opportunity for public comment on this supplemental NPRM. Also, because of the expanded scope, we must supersede, rather than revise, the AD 2006–16–03. Costs of Compliance There are about 457 airplanes of the affected design in the worldwide fleet. The following table provides the estimated costs for U.S. operators to comply with this supplemental NPRM. ESTIMATED COSTS Work hours Average labor rate per hour Parts Cost per airplane Number of U.S.-registered airplanes 2–17 ................................. $80 Up to $4,169 ................... Up to $5,529 ................... 281 jlentini on PROD1PC65 with PROPOSALS 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 VerDate Aug<31>2005 17:02 Nov 25, 2008 Jkt 217001 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 supplemental NPRM and placed 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, Incorporation by reference, Safety.

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Supplemental notice of proposed rulemaking (NPRM); reopening of 
comment period.

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

SUMMARY: The FAA is revising an earlier NPRM for an 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 original NPRM would have revised an 
existing AD that 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. The original NPRM proposed to revise 
the applicability to clarify the identity of the affected airplanes. 
The original NPRM resulted from fuel system reviews conducted by the 
manufacturer. This new action proposes to revise the applicability to 
add and remove certain airplanes, and to add a requirement to 
reposition or replace two bonding straps for certain airplanes. This 
new action also proposes to supersede, rather than revise, the existing 
AD. We are proposing this supplemental NPRM 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.

DATES: We must receive comments on this supplemental NPRM by December 
22, 2008.

Discussion

    We proposed to amend part 39 of the Federal Aviation Regulations 
(14 CFR part 39) with a notice of proposed rulemaking (NPRM) for an AD 
(the ``original NPRM'') to revise AD 2006-16-03, amendment 39-14703 (71 
FR 43962, August 3, 2006). The original NPRM applied 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, and MD-10-
10F and MD-10-30F airplanes. The affected airplanes are identified by 
the manufacturer's fuselage numbers referenced in the applicable 
McDonnell Douglas DC-10 service bulletin (Service Bulletin 53-109, 
Revision 4, dated October 7, 1992; or Service Bulletin 53-111, Revision 
3, dated August 24, 1992).
    The original NPRM was published in the Federal Register on November 
13, 2007 (72 FR 63836). The original NPRM proposed to revise AD 2006-
16-03 to clarify the identity of the affected airplanes in the 
applicability.

Actions Since Original NPRM Was Issued

    Since we issued the original NPRM, Boeing has revised the service 
bulletins. Service Bulletin DC10-53-111, Revision 5, dated March 19, 
2008, and DC10-53-109, Revision 6, dated July 10, 2008, correct 
effectivity errors (to add and remove certain airplanes incorrectly 
excluded or included from previous versions). In addition, Service 
Bulletin DC10-53-109, Revision 5, now includes an action to reposition 
two bonding straps by using new bonding straps that are less 
susceptible to cracking. Revision 6 of Service Bulletin DC10-53-109 
provides a faster and easier method, which involves replacing the 
straps with longer straps instead of relocating them.
    The revised service bulletins have been approved by the FAA as 
alternative methods of compliance (AMOCs) with the requirements of AD 
2006-16-03. Paragraph (i)(3) has been revised in this supplemental NPRM 
to include information about these AMOCs.

FAA's Determination and Proposed Requirements of the Supplemental NPRM

    The changes discussed above expand the scope of the original NPRM; 
therefore, we have determined that it is necessary to reopen the 
comment period for revising AD 2006-16-03 to provide additional 
opportunity for public comment on this supplemental NPRM. Also, because 
of the expanded scope, we must supersede, rather than revise, the AD 
2006-16-03.

Costs of Compliance

    There are about 457 airplanes of the affected design in the 
worldwide fleet. The following table provides the estimated costs for 
U.S. operators to comply with this supplemental NPRM.

                                                                     Estimated Costs

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 supplemental NPRM and placed 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, Incorporation by 
reference, 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. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

    2. The Federal Aviation Administration (FAA) amends Sec.  39.13 by 
removing amendment 39-14703 (71 FR 43962, August 3, 2006) and adding 
the following new airworthiness directive (AD):

McDonnell Douglas: Docket No. FAA-2007-0186; Directorate Identifier 
2007-NM-226-AD.

Comments Due Date

    (a) The FAA must receive comments on this AD action by December 
22, 2008.

Affected ADs

    (b) This AD supersedes AD 2006-16-03.

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.
