ACTION : Final rule. SUMMARY : We are adopting a new airworthiness directive (AD) for certain McDonnell Douglas Model MD–90–30 airplanes. This AD requires installing fuses and wire protection in certain wing and fuel tank spars. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent possible damage to the fuel level float or pressure switch wires. Such damage could become a potential ignition source inside the fuel tank, and, when combined with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane. DATES : This AD is effective July 7, 2009. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of July 7, 2009. ADDRESSES : For service information identified in this AD, contact Boeing Commercial Airplanes, Attention: Data & Services Management, 3855 Lakewood Boulevard, MC D800–0019, Long Beach, California 90846–0001; telephone 206–544–5000, extension 2; fax 206–766–5683; e-mail VerDate Nov<24>2008 15:57 Jun 01, 2009 Jkt 217001 PO 00000 Frm 00011 Fmt 4700 Sfmt 4700 E:\FR\FM\02JNR1.SGM 02JNR1

SUPPLEMENTARY INFORMATION : Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an airworthiness directive (AD) that would apply to certain McDonnell Douglas Model MD– 90–30 airplanes. That NPRM was published in the Federal Register on March 10, 2009 (74 FR 10202). That NPRM proposed to require installing fuses and wire protection in certain wing and fuel tank spars. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public. 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 15 airplanes of U.S. registry. The following table provides the estimated costs for U.S. operators to comply with this AD. T ABLE —E STIMATED C OSTS Action Work hours Average labor rate per hour Parts Cost per product Number of U.S.-reg- istered airplanes Fleet cost Installation, depending on group. 20 or 26 ....... $80 $1,132 or $1,822 ........ $2,732 or $3,902 ........ 15 $40,980 to $58,530. 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), 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. You can find our regulatory evaluation and the estimated costs of compliance in the AD Docket.

SUPPLEMENTARY INFORMATION : The Burlington Northern Railway Company has requested a temporary deviation in order to perform necessary maintenance on the Conley joints of the Galveston Causeway Railroad Bascule Bridge across the Gulf Intracoastal Waterway, mile 357.2 west of Harvey Locks, at Galveston, Galveston County, Texas. The maintenance is essential for the continued safe operation of the railroad bridge. This temporary deviation will allow the bridge to remain in the closed- to-navigation position from 7 a.m. until 3 p.m. on Tuesday, June 9, 2009. The bridge will open for the passage of vessels at noon for all vessels to transit through the bridge. Currently, the draw opens on signal for the passage of vessels. The bridge has a vertical clearance of 10 feet above mean high water in the closed-to-navigation position. Navigation at the site of the bridge consists mainly of tows with barges and some recreational pleasure craft. Due to prior experience, as well as coordination with waterway users, it has been determined that this closure will not have a significant effect on these vessels. No alternate routes are available. This closure is considered necessary for repair of the bridge. In accordance with 33 CFR 117.35(e), the drawbridge must return to its regular operating schedule immediately at the end of the designated time period. This deviation from the operating regulations is authorized under 33 CFR 117.35. Dated: May 18, 2009. David M. Frank, Bridge Administrator. [FR Doc.
