[Federal Register Volume 81, Number 32 (Thursday, February 18, 2016)] [Rules and Regulations] [Pages 8140-8143] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2016-03219] ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2015-2460; Directorate Identifier 2014-NM-163-AD; Amendment 39-18396; AD 2016-04-02] RIN 2120-AA64 Airworthiness Directives; The Boeing Company Airplanes AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are superseding Airworthiness Directive (AD) 2010-26-10, which applied to certain The Boeing Company Model 747-200C, -200F, - 400, -400D, and -400F series airplanes. AD 2010-26-10 required repetitive inspections for cracking of the lap joints, modification of certain lap joints, and certain post-repair inspections of the lap joints. This new AD adds new repetitive post-modification inspections for cracking in the lap joints, and repair if necessary. This AD was prompted by an evaluation by the design approval holder (DAH) which indicated that certain lap joints are subject to widespread fatigue damage (WFD). We are issuing this AD to detect and correct fatigue cracking in certain lap joints, which could result in rapid depressurization and consequent reduced structural integrity of the airplane. DATES: This AD is effective March 24, 2016. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of March 24, 2016.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2010-26-10, Amendment 39-16549 (75 FR 81427, December 28, 2010). AD 2010-26-10 applied to certain The Boeing Company Model 747-200C, -200F, -400, -400D, and -400F series airplanes. The NPRM published in the Federal Register on July 9, 2015 (80 FR 39394). The NPRM was prompted by an evaluation by the DAH that indicated that certain lap joints are subject to WFD. The NPRM proposed to continue to require repetitive inspections for cracking of the lap joints, modification of certain lap joints, and certain post-repair inspections of the lap joints. The NPRM also proposed to require new repetitive post-modification inspections for cracking in the lap joints, and repair if necessary. We are issuing this AD to detect and correct fatigue cracking in certain lap joints, which could result in rapid depressurization and consequent reduced structural integrity of the airplane. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the NPRM (80 FR 39394, July 9, 2015) and the FAA's response to each comment. United Airlines concurred with the NPRM. Request To Correct Typographical Error Boeing asked that we correct the reference in the ``Related Service Information under 1 CFR part 51'' from ``. . . sections 41, 42, and 43'' to ``. . . sections 41, 42, and 46.'' Boeing stated that section 43 should be section 46, and noted that this is a typographical error. We agree with the commenter's request for the reason provided. We have corrected this typographical error in ``Related Service Information under 1 CFR part 51'' accordingly. Request To Clarify Certain Requirements Boeing asked that we clarify paragraph (i)(1) of the proposed AD (80 FR 39394, July 9, 2015) by including ``per Table 7'' in that paragraph. Boeing also asked that we clarify paragraph (i)(3) of the proposed AD by including ``per Table 10'' in that paragraph. We agree that clarification is necessary but we do not agree to change paragraphs (i)(1) and (i)(3) of this AD. Paragraph (i) of this AD specifies doing the applicable inspections in paragraphs (i)(1), (i)(2), or (i)(3) of this AD, in accordance with the Accomplishment Instructions of the referenced service information; and repeating the applicable inspections at the applicable times specified in Tables 7, 8, 9, and 10 of paragraph 1.E., ``Compliance,'' of Boeing Alert Service Bulletin 747-53A2499, Revision 3, dated July 15, 2014. In each of these tables the applicable groups are identified and match the groups identified in paragraphs (i)(1), (i)(2), and (i)(3) of this AD. We refer to the tables in paragraph 1.E., ``Compliance,'' of service information for the applicable compliance times and not for how to accomplish the required actions. Therefore, we have not changed this AD in this regard. 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, with minor editorial changes. We have determined that these minor changes:Are consistent with the intent that was proposed in the NPRM (80 FR 39394, July 9, 2015) for correcting the unsafe condition; and Do not add any additional burden upon the public than was already proposed in the NPRM (80 FR 39394, July 9, 2015). Related Service Information Under 1 CFR Part 51 We reviewed Boeing Alert Service Bulletin 747-53A2499, Revision 3, dated July 15, 2014. The service information describes procedures for body skin lap joint inspections and modifications in sections 41, 42, and 46. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section. Costs of Compliance We estimate that this AD affects 120 airplanes of U.S. registry. We estimate the following costs to comply with this AD: Estimated Costs ---------------------------------------------------------------------------------------------------------------- Cost on U.S. Action Labor cost Parts cost Cost per product operators ---------------------------------------------------------------------------------------------------------------- Pre-modification inspections Up to 675 work-hours x $0 Up to $57,375 per Up to $6,885,000 [retained action from AD 2010- $85 per hour = up to inspection cycle. per inspection 26-10, Amendment 39-16549 (75 $57,375. cycle. FR 81427, December 28, 2010)]. Modification [retained action Up to 5,819 work-hours 0 Up to $494,615.... Up to $59,353,800. from AD 2010-26-10, Amendment x $85 per hour = up to 39-16549 (75 FR 81427, $494,615. December 28, 2010)]. New proposed post-modification Up to 105 work-hours x 0 Up to $8,925 per Up to $1,071,000 inspections. $85 per hour = up to inspection cycle. per inspection $8,925. cycle. ---------------------------------------------------------------------------------------------------------------- [[Page 8142]] We have received no definitive data that would enable us to provide a cost estimate 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: PART 39--AIRWORTHINESS DIRECTIVES 0 1.
