RIN 2120-AA64
 AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT).
 ACTION: Final rule.
 SUMMARY: The FAA is superseding an existing airworthiness directive (AD), which applies to certain transport category airplanes identified above. That AD currently requires modification of the reinforced flight deck door and other actions related to the reinforced flight deck door. Those other actions include modifying the door, inspecting and modifying wiring in the area, and revising the maintenance program to require more frequent testing of the decompression panels of the flight deck door. This new AD continues to require the existing requirements. This new AD adds airplanes to the existing requirement of a one-time inspection for chafing of wire bundles in the area of the flight deck door and corrective actions if necessary. This proposed AD also removes certain airplanes from the applicability. This AD results from a report of smoke and fumes in the cockpit of a Model 737-300 series airplane. We are issuing this AD to prevent inadvertent release of the decompression latch and consequent opening of the decompression panel in the flight deck door, or penetration of the flight deck door by smoke, any of which could result in injury to the airplane flightcrew. We are also proposing this AD to detect and correct wire chafing, which could result in arcing, fire, and/or reduced controllability of the airplane.
 DATES: This AD becomes effective June 27, 2007. On July 19, 2005 (70 FR 34316, June 14, 2005), the Director of the Federal Register approved the incorporation by reference of certain service information. On July 25, 2003 (68 FR 41063, July 10, 2003), the Director of the Federal Register approved the incorporation by reference of certain other service information.

                     section. Discussion The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that supersedes AD 2005-12-05, amendment 39-14121 (70 FR 34316, June 14, 2005). (A correction of that AD was published in the 
                    **Federal Register**
                     on June 28, 2005 (70 FR 37152).) The existing AD applies to Boeing Model 737-200, -300, -400, -500, -600, -700, -800, and -900 series airplanes; Boeing Model 757-200 and -300 series airplanes; and McDonnell Douglas Model DC-10-10, DC-10-10F, DC-10-30, DC-10-30F, DC-10-40, MD-10-10F, MD-10-30F, MD-11, and MD-11F airplanes. That NPRM was published in the 
                    **Federal Register**
                     on January 19, 2007 (72 FR 2475). That NPRM proposed to continue to require modification of the reinforced flight deck door and other actions related to the reinforced flight deck door. Those other actions include modifying the door, inspecting and modifying wiring in the area, and revising the maintenance program to require more frequent testing of the decompression panels of the flight deck door. That NPRM also proposed to add airplanes to the existing requirement of a one-time inspection for chafing of wire bundles in the area of the flight deck door and corrective actions if necessary. That NPRM also proposed to remove certain airplanes from the applicability. Comments We provided the public the opportunity to participate in the development of this AD. We have considered the comments that have been received on the NPRM. Support for the NPRM Boeing, United Airlines, and the Air Line Pilots Association, International (ALPA) support the intent of the NPRM. Request To Issue a Separate AD United Airlines requests that rather than superseding the existing AD, we issue a separate AD action since the new proposed actions are applicable only to the Model 737-300, -400, and -500 series airplanes. The commenter states that if the existing AD is superseded, numerous documents must be updated for all airplane models affected by the earlier actions. The commenter asserts that superseding an already complex compliance plan provides an opportunity for non-compliance and unnecessarily increases an operator's workload. 
                    ( print page 28833) We acknowledge that the less burdensome approach is to issue a separate AD that applies only to the Model 737-300, -400, and -500 series airplanes. Further, our normal policy is to issue a separate AD when any new requirements would affect only a small portion of the affected airplanes, so that we do not burden operators with the workload associated with revising maintenance record entries. However, in this case, we determined that the existing AD needed to be superseded because we are also removing certain airplanes from the applicability. For certain operators, this final rule is relieving in nature. Therefore, we have not revised this AD in this regard. Clarification of Alternative Method of Compliance (AMOC) Paragraph We have revised this action to clarify the appropriate procedure for notifying the principal inspector before using any approved AMOC on any airplane to which the AMOC applies. Conclusion We have carefully reviewed the available data, including the comments that have been received, and determined that air safety and the public interest require adopting the AD with the change described previously. We have determined that this change will neither increase the economic burden on any operator nor increase the scope of the AD. Costs of Compliance We have determined that about 1,047 additional airplanes (Model 737-300, -400, and -500 series airplanes) in the worldwide fleet are subject to this AD; therefore, there are now about 3,423 airplanes of the affected design in the worldwide fleet. The following table provides the estimated costs, at an average labor rate of $80 per work hour, for U.S. operators to comply with this AD. 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 AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on 
                    ( print page 28834)
                    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**
