**ACTION :**  Final rule.

**SUMMARY :**  We are superseding Airworthiness Directive (AD) 2009–26– 16 for certain The Boeing Company Model MD–11 and MD–11F airplanes. AD 2009–26–16 required inspecting to determine if wires touch the upper surface of the center upper auxiliary fuel tank, and marking the location, as necessary; inspecting all wire bundles above the center upper auxiliary fuel tank for splices and damage; inspecting for damage to the fuel vapor barrier seal and upper surface of the center upper auxiliary fuel tank; and performing corrective actions, as necessary. AD 2009–26–16 also required installing nonmetallic barrier/shield sleeving, new clamps, new attaching hardware, and a new extruded channel. This new AD requires inspections of additional center upper auxiliary fuel tank locations and corrective actions as necessary. This AD was prompted by reports that identified additional locations where inspections and corrective actions of the center upper auxiliary fuel tank are needed. We are issuing this AD to reduce the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.

**SUPPLEMENTARY INFORMATION :** 

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR Part 39 to supersede AD 2009–26–16, Amendment 39–16155 (74 FR 69249, December 31, 2009). AD 2009–26–16 applied to certain The Boeing Company Model MD–11 and MD–11F airplanes. The NPRM published in the Federal Register on March 14, 2013 (78 FR 16198). The NPRM was prompted by reports that identified additional locations where inspections and corrective actions of the center upper auxiliary fuel tank are needed. The NPRM proposed to continue to require inspecting to determine if wires touch the upper surface of the center upper auxiliary fuel tank, and marking the location, as necessary; inspecting all wire bundles above the center upper auxiliary fuel tank for splices and damage; inspecting for damage to the


### 9393 Federal Register / Vol. 79, No. 33 / Wednesday, February 19, 2014 / Rules and Regulations

fuel vapor barrier seal and upper surface of the center upper auxiliary fuel tank; and performing corrective actions, as necessary. The NPRM also proposed to continue to require installing nonmetallic barrier/shield sleeving, new clamps, new attaching hardware, and a new extruded channel. The NPRM also proposed to require inspections of the center upper auxiliary fuel tank at additional locations and corrective actions as necessary. We are issuing this AD to reduce the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.

Comments

We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the proposal (78 FR 16198, March 14, 2013) and the FAA’s response to each comment.
Request for Approval of Alternative Methods of Compliance (AMOCs)

FedEx requested that AMOCs previously approved for AD 2009–26– 16, Amendment 39–16155 (74 FR 69249, December 31, 2009), be approved as AMOCs for the requirements of the NPRM (78 FR 16198, March 14, 2013). FedEx also requested that Boeing Service Bulletin MD11–28–126, Revision 4, dated November 29, 2011, be revised to incorporate changes made by seven Boeing Information Notices, which were not FAA-approved.

We acknowledge the commenter’s request. However, paragraph (k)(4) of the NPRM (78 FR 16198, March 14, 2013) already states that AMOCs approved for AD 2009–26–16, Amendment 39–16155 (74 FR 69249, December 31, 2009), are approved as AMOCs for the corresponding requirements of this AD. Also, the changes in all seven Boeing Information Notices were either incorporated or resolved in Boeing Service Bulletin MD11–28–126, Revision 2, dated November 18, 2010, except for Boeing MD11 Service Bulletin Information Notice MD11–28–126 IN 07, December 3, 2012, which was issued for information only, and therefore does not affect the requirements of this final rule. No changes have been made to this final rule in this regard.
Request To Extend Compliance Time

FedEx requested that the compliance time for the NPRM (78 FR 16198, March 14, 2013) be extended from ‘‘Within 60 months after February 4, 2010 (the effective date of AD 2009–26–16),’’ for the retained inspection and actions specified in paragraphs (g)(1) through (g)(5) of the NPRM to 72 months, or February 4, 2016, at a minimum. FedEx stated that work would have to be accomplished by February 4, 2015, and due to the labor intensive nature of the work, 18 to 20 months is not enough time to fit into a ‘C’ check time interval.

We do not agree with FedEx’s request. In developing an appropriate compliance time for this action, we considered not only the degree of urgency associated with addressing the subject unsafe condition, but the manufacturer’s recommendation for an appropriate compliance time, the availability of required parts, and the practical aspect of installing the required modification within an interval of time that corresponds to the typical scheduled maintenance for the majority of affected operators. The retained inspection and corrective action were previously required by AD 2009–26–16, Amendment 39–16155 (74 FR 69249, December 31, 2009), so operators should have already completed or be scheduled to have the work completed. Under the provisions of paragraph (k) of this final rule, we may approve requests for adjustments to the compliance time if data are submitted to substantiate that such an adjustment would provide an acceptable level of safety.
Request To Revise Costs of Compliance

FedEx requested that the Costs of Compliance be revised since material costs have drastically increased. FedEx stated that Boeing Service Bulletin MD11–28–126, Revision 4, dated November 29, 2011, (which we referred to in the NPRM (78 FR 16198, March 14, 2013), as the appropriate source of service information for doing the actions) specifies a cost of $18,139 for kit part number SB11280126–11. FedEx stated that a recent quote for this kit is $25,904. Also, the original cost for kit SB11280126–13 was $12,268; it is now $17,568.

We agree with the request to revise the Costs of Compliance because current costs for kits differ greatly from when the NPRM (78 FR 16198, March 14, 2013) was issued. The retained actions from AD 2009–26–16, Amendment 39– 16155 (74 FR 69249, December 31, 2009), had a parts cost of $9,405 to $12,201; the revised parts cost is $15,708 to $28,005. The parts cost for the new action was revised from $2,863 to $6,166. We have revised the information contained in the Costs of Compliance accordingly.
Explanation of Additional Change Made to the Costs of Compliance

We have revised this AD to revise the Costs of Compliance, which incorrectly specified inspection and installation costs for four Group 6 airplanes as new actions. We have revised the information contained in the Costs of Compliance tables by removing the row containing Group 6 airplanes accordingly.

Conclusion

We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this AD as proposed except for minor editorial changes. We have determined that these minor changes:

• Are consistent with the intent that was proposed in the NPRM (78 FR 16198, March 14, 2013) for correcting the unsafe condition; and

• Do not add any additional burden upon the public than was already proposed in the NPRM (78 FR 16198, March 14, 2013).
Costs of Compliance

We estimate that this AD affects 125 airplanes of U.S. registry.

We estimate the following costs to comply with this AD:

We have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in this AD.
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),

(3) Will not affect intrastate aviation in Alaska, and

(4) 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.
