You can examine the AD docket on the Internet at https:// dms.dot.gov, or in person at the Docket Management Facility office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The Docket Management Facility office (telephone (800) 647–5227) is located on the plaza level of the Nassif Building at the DOT street address stated in the ADDRESSES section. The FAA proposed to amend 14 CFR Part 39 with an AD for certain Airbus Model A318, A319, A320, and A321 series airplanes equipped with certain forward and aft passenger door emergency escape slides. That action, published in the Federal Register on November 3, 2004 (69 FR SUPPLEMENTARY INFORMATION: 1177 63960), proposed to require modifying the forward and aft door slides. Comments We provided the public the opportunity to participate in the development of this AD. No comments have been submitted on the proposed AD 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 The following table provides the estimated costs for U.S. operators to comply with this AD, at an average labor rate of $65 per work hour. ESTIMATED COSTS Action Work hours per slide Slides per airplane Parts Cost per airplane Number of U.S. registered airplanes Fleet cost Modification ...................................................................... 1 2 Free $130 648 $84,240 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. VerDate jul<14>2003 18:52 Jan 05, 2005 Jkt 205001 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. See the ADDRESSES section for a location to examine the regulatory evaluation.

ACTION: Final rule. AGENCY: SUMMARY: This amendment adopts a new airworthiness directive (AD), that is applicable to certain Boeing Model 767– 300 and 767–300F series airplanes equipped with General Electric or Pratt & Whitney engines. This AD requires reworking the wing-to-strut diagonal braces and the aft pitch load fittings of the wings, and reinstalling the diagonal braces with new fuse pins and associated hardware. This action is necessary to prevent undetected loss of the diagonal brace fuse pins of the wings and consequent increased loads in other wing-to-strut joints, which could result in separation of the struts and engines from the wings. This action is intended to address the identified unsafe condition. DATES: Effective February 10, 2005.

PO 00000 Frm 00018 Fmt 4700 Sfmt 4700 A proposal to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) to include an airworthiness directive (AD) that is applicable to certain Boeing Model 767–300 and 767–300F series airplanes equipped with General Electric or Pratt & Whitney engines was published in the Federal Register on April 1, 2004 (69 FR 17080). That action proposed to require reworking the wingto-strut diagonal braces and the aft pitch load fittings of the wings, and reinstalling the diagonal braces with new fuse pins and associated hardware. For certain airplanes, that proposal would require replacing the bushings of the aft pitch load fittings, installing new fuse pins, and reworking the fittings, as applicable SUPPLEMENTARY INFORMATION: Comments Interested persons have been afforded an opportunity to participate in the making of this amendment. Due consideration has been given to the comments received. Request for Credit for Actions Accomplished per Revision 1 of the Service Bulletin Two commenters, the manufacturer and one operator, request that the FAA give credit for actions accomplished in accordance with Boeing Alert Service Bulletin 767–54A0096, Revision 1, dated July 12, 2001. The commenters indicate that the proposed AD references Boeing Alert Service Bulletin 767–54A0096, Revision 2, dated December 18, 2003, as the appropriate source of information, and point out that Revision 2 states that no more work is necessary on airplanes modified in accordance with Revision 1. We do not agree with the commenters’ request. The statement in Revision 2 of the service bulletin that ‘‘No more work is necessary on airplanes changed as shown in Revision 1 of this service bulletin,’’ is incorrect. Revision 2 of the service bulletin revises, among other changes, the bushing swage lip dimension in Figures 3 and 6 of Revision 1 of the service bulletin. Therefore, we have determined that accomplishing the rework specified in Revision 1 does not adequately address the identified unsafe condition. In addition, since we issued the proposed AD, Boeing has issued and we have reviewed Service Bulletin Information Notice (IN) 767–54A0096 IN 03, dated April 15, 2004, which corrects an additional dimension (i.e., the bushing swage groove radius dimension) in Figures 3 and 6 of Revision 2.

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. See the ADDRESSES section for a location to 
examine the regulatory evaluation.

Unsafe Condition

contact between the inflation hose and fabric roll, within a short 
period of time after inflation of the emergency escape slides, can 
rupture

the inflation hose at its end fittings. We are issuing this AD to 
prevent interference between the inflation hose and slide fabric and 
rupture of the inflation hose, which could result in incomplete 
inflation of the emergency escape slides and consequent 
unavailability of those slides during an emergency evacuation.
