Applicability Special conditions are initially applicable to the model for which they are issued. Should the applicant apply for a supplemental type certificate to modify any other model included on the same type certificate to incorporate the same novel or unusual design feature, the special conditions would also apply to the other model under the provisions of § 21.101(a)(1). Conclusion This action affects only certain novel or unusual design features on one model of airplane. It is not a rule of general applicability and affects only the applicant who applied to the FAA for approval of these features on the airplane. The substance of these special conditions has been subjected to the notice and comment period in several prior instances and has been derived without substantive change from those previously issued. It is unlikely that prior public comment would result in a significant change from the substance contained herein. Therefore, because a delay would significantly affect the certification of the airplane, which is imminent, the FAA has determined that prior public notice and comment are unnecessary and impracticable, and good cause exists for adopting these special conditions upon issuance. The FAA is requesting comments to allow interested persons to submit views that may not have been submitted in response to the prior opportunities for comment described above.

Discussion The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to certain McDonnell Douglas Model MD–11, MD–11F, DC–10–30 and DC–10–30F (KC–10A and KDC–10), DC– 10–40, DC–10–40F, and MD–10–30F airplanes. That NPRM was published in the Federal Register on June 5, 2007 (72 FR 31003). That NPRM proposed to require measuring the electrical resistance of the bond between the No. 2 fuel transfer pump adapter surface of the fuel tank and the fuel transfer pump E:\FR\FM\12SER1.SGM 12SER1 Federal Register / Vol. 72, No. 176 / Wednesday, September 12, 2007 / Rules and Regulations housing flange, and performing corrective and other specified actions as applicable. Comments We provided the public the opportunity to participate in the development of this AD. We received no comments on the NPRM or on the determination of the cost to the public. Conclusion We have carefully reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed. List of Subjects in 14 CFR Part 39 Costs of Compliance There are about 573 airplanes of the affected design in the worldwide fleet. This AD affects about 399 airplanes of U.S. registry. The required measurement takes about 1 work hour per airplane, at an average labor rate of $80 per work hour. Based on these figures, the estimated cost of this AD for U.S. operators is $31,920, or $80 per airplane. 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. jlentini on PROD1PC65 with RULES Regulatory Findings We have determined that 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; VerDate Aug<31>2005 16:11 Sep 11, 2007 Jkt 211001 (2) Is not a ‘‘significant rule’’ under 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.

Differences Between This AD and the MCAI or Service Information We have reviewed the MCAI and related service information and, in general, agree with their substance. But we might have found it necessary to use different words from those in the MCAI to ensure the AD is clear for U.S. operators and is enforceable. In making these changes, we do not intend to differ substantively from the information provided in the MCAI and related service information. We might also have required different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are highlighted in a NOTE within the AD. Costs of Compliance We estimate that this AD will affect 7 products of U.S. registry. We also estimate that it will take about 40 workhours per product to comply with basic requirements of this AD. The average labor rate is $80 per work-hour. Required parts will cost about $50 per product. Based on these figures, we estimate the cost of this AD to the U.S. operators to be $22,750 or $3,250 per product.

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain McDonnell Douglas Model MD-11, MD-11F, DC-10-30 and DC-10-30F 
(KC-10A and KDC-10), DC-10-40, DC-10-40F, and MD-10-30F airplanes. This 
AD requires measuring the electrical resistance of the bond between the 
No. 2 fuel transfer pump adapter surface of the fuel tank and the fuel 
transfer pump housing flange, and performing corrective and other 
specified actions as applicable. This AD results from a design review 
of the fuel tank systems. We are issuing this AD to prevent inadequate 
bonding between the No. 2 fuel transfer pump adapter surface of the 
fuel tank and the fuel transfer pump housing flange. Inadequate bonding 
could result in a potential ignition source inside the fuel tank if the 
fuel transfer pump and structure interface are not submerged in fuel, 
which, in combination with flammable fuel vapors, could result in a 
fuel tank explosion and consequent loss of the airplane.

DATES: This AD becomes effective October 17, 2007.

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to include an AD that would apply to certain McDonnell 
Douglas Model MD-11, MD-11F, DC-10-30 and DC-10-30F (KC-10A and KDC-
10), DC-10-40, DC-10-40F, and MD-10-30F airplanes. That NPRM was 
published in the Federal Register on June 5, 2007 (72 FR 31003). That 
NPRM proposed to require measuring the electrical resistance of the 
bond between the No. 2 fuel transfer pump adapter surface of the fuel 
tank and the fuel transfer pump

[[Page 51995]]

housing flange, and performing corrective and other specified actions 
as applicable.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We received no comments on the NPRM or on the 
determination of the cost to the public.

Conclusion

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

Costs of Compliance

    There are about 573 airplanes of the affected design in the 
worldwide fleet. This AD affects about 399 airplanes of U.S. registry. 
The required measurement takes about 1 work hour per airplane, at an 
average labor rate of $80 per work hour. Based on these figures, the 
estimated cost of this AD for U.S. operators is $31,920, or $80 per 
airplane.

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 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); 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 AD and placed it in the AD docket. See the ADDRESSES 
section for a location to examine the regulatory evaluation.

    (1) If the resistance measurement is 2.5 milliohms or less: No 
further action is required by this paragraph.
    (2) If the resistance measurement is more than 2.5 milliohms: 
Before further flight, electrically bond the fuel tank No. 2 fuel 
transfer pump housing surfaces in accordance with the service 
bulletin.
    (3) Before further flight thereafter, do an electrical 
resistance bonding test to verify the electrical resistance between 
the fuel transfer pump housing and the structure is 2.5 milliohms 
maximum. If that electrical resistance is not achieved, rework the 
electrical bond until the electrical resistance is achieved. Do the 
actions in accordance with the service bulletin.
