[Federal Register Volume 81, Number 53 (Friday, March 18, 2016)] [Rules and Regulations] [Pages 14693-14698] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2016-05249] ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2015-2961; Directorate Identifier 2014-NM-145-AD; Amendment 39-18430; AD 2016-05-12] 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) 2012-15-13, for certain The Boeing Company Model 747-100B SUD, 747-300, 747-400, and 747-400D series airplanes; and Model 747-200B series airplanes having a stretched upper deck. AD 2012-15-13 required inspections for cracking and discrepancies of certain fasteners; modification of the frame-to-tension-tie joints; repetitive post-modification inspections; related investigative and corrective actions if necessary; and repetitive inspections for cracking in the tension tie channels, and repair if necessary. For certain airplanes, AD 2012-15-13 also required an inspection to determine if the angle is installed correctly, and re- installation if necessary; and an inspection at the fastener locations where the tension tie previously attached to the frame prior to certain modifications, and repair if necessary. This new AD adds a new inspection for cracking in the tension tie channels and post- modification inspections of the modified tension ties for cracking, and repair if necessary. This AD was prompted by an evaluation indicated that the upper deck is subject to widespread fatigue damage (WFD). We are issuing this AD to prevent fatigue cracking of the tension ties, shear webs, and frames of the upper deck, which could result in rapid decompression and reduced structural integrity of the airplane. DATES: This AD is effective April 22, 2016. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of April 22, 2016. The Director of the Federal Register approved the incorporation by reference of certain other publications listed in this AD as of September 12, 2012 (77 FR 47267, August 8, 2012).

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2012-15-13, Amendment 39-17142 (77 FR 47267, August 8, 2012) (``AD 2012-15-13''). AD 2012-15-13 applied to certain The Boeing Company Model 747-100B SUD, 747-300, 747-400, and 747-400D series airplanes; and Model 747-200B series airplanes having a stretched upper deck. The NPRM published in the Federal Register on July 24, 2015 (80 FR 43974) (``the NPRM''). The NPRM was prompted by an evaluation that indicated that the upper deck is subject to WFD. The NPRM proposed to continue to require inspections for cracking and discrepancies of certain fasteners; modification of the frame-to- tension-tie joints; repetitive post-modification inspections; related investigative and corrective actions if necessary; and repetitive inspections for cracking in the tension tie channels, and repair if necessary. For certain airplanes, the NPRM also proposed to continue to require an inspection to determine if the angle is installed correctly, and re-installation if necessary; and an inspection at the fastener locations where the tension tie previously attached to the frame prior to certain modifications, and repair if necessary. The NPRM also proposed to add a new inspection for cracking in the tension tie channels and post-modification inspections of the modified tension ties for cracking, and repair if necessary. We are issuing this AD to prevent fatigue cracking of the tension ties, shear webs, and frames of the upper deck, which could result in rapid decompression and 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 and the FAA's response to each comment. Support for the NPRM United Airlines concurred with the contents of the NPRM. Requests To Include Options To Perform Inspections in Revised Service Information Boeing and United Parcel Service (UPS) asked that we add a new paragraph to the proposed AD that includes an option to perform the inspections specified in Boeing Alert Service Bulletin 747-53A2507, Revision 2, dated May 9, 2014. Boeing stated that these inspections are equivalent to the inspections done in accordance with Boeing Alert Service Bulletin 747-53A2507, Revision 1, dated January 14, 2010. UPS recommended that Boeing Alert Service Bulletin 747-53A2507, Revision 2, dated May 9, 2014, be added to paragraphs (g) through (o) of the proposed AD. UPS noted that, for clarity, the proposed AD should refer to the revised service information rather than relying on paragraph (t)(4) of the proposed AD, which allows alternative methods of compliance (AMOCs) previously approved for AD 2012-15-13 to be approved as AMOCs for the proposed AD. We acknowledge the commenters' requests and note that we normally add reference to later revisions of service information in the restated paragraphs of supersedure ADs. However, in most cases, the later revisions do not include new compliance times and the procedures are closely aligned with those in the previous service information. Boeing Alert Service Bulletin 747-53A2507, Revision 2, dated May 9, 2014, adds alternative compliance times for certain airplanes and refers to different procedures in the Accomplishment Instructions of Boeing Alert Service Bulletin 747-53A2507, Revision 2, dated May 9, 2014, for accomplishing the actions required by AD 2012-15-13. Therefore, we cannot simply add a reference to paragraphs (g) through (o) of this AD as requested by the commenter. We have determined that, in this case, adding additional paragraphs to this AD to specify the alternative method of compliance, including new compliance times and procedures, is not necessary since Boeing Alert Service Bulletin 747-53A2507, Revision 2, dated May 9, 2014, was already approved as an AMOC to AD 2012-15-13. As stated by the commenter, paragraph (t)(4) of this AD already allows the use of previous AMOCs, such as Boeing Alert Service Bulletin 747- 53A2507, Revision 2, dated May 9, 2014, as AMOCs for the corresponding provisions of this AD. We have made no change to this AD in this regard. Request To Include an Alternative Compliance Time for the Modification Boeing and UPS asked that we add a new paragraph to allow an alternative compliance time for airplanes on which the station (STA) 1120, 1160, 1200, and 1220 tension ties were modified during a freighter conversion, as provided in table 4 of paragraph 1.E., ``Compliance,'' of Boeing Alert Service Bulletin 747-53A2559, Revision 2, dated May 13, 2014. Boeing stated that the compliance time for modification of those airplanes can be increased because the modification has been done during a freighter conversion. UPS noted that paragraph (p) of the proposed AD should be changed to require modification and all related inspections and corrective actions be accomplished in accordance with Boeing Alert Service Bulletin 747- 53A2559, Revision 2, dated May 13, 2014, at the applicable time specified in Boeing Service Bulletin 747-53A2559, Revision 1, dated August 4, 2011; or Boeing Alert Service Bulletin 747-53A2559, Revision 2, dated May 13, 2014. We agree with the commenter to include the alternative compliance times for certain airplanes to accomplish the actions required by paragraph (p) of this AD. We have added a new paragraph (p)(3) to this AD for Group 3 through 5, Configuration 1 airplanes identified in Boeing Alert Service Bulletin 747-53A2559, Revision 2, dated May 13, 2014, to specify that operators may accomplish the actions required by paragraph (p) of this AD within the applicable compliance times specified in paragraph 1.E., ``Compliance,'' of Boeing Alert Service Bulletin 747-53A2559, Revision 2, dated May 13, 2014. Conclusion We reviewed the relevant data, considered the comments received, and determined that air safety and the [[Page 14695]] public interest require adopting this AD with the changes described previously and minor editorial changes. We have determined that these minor changes:Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and Do not add any additional burden upon the public than was already proposed in the NPRM. We also determined that these changes will not increase the economic burden on any operator or increase the scope of this AD. Related Service Information Under 1 CFR Part 51 We reviewed Boeing Alert Service Bulletin 747-53A2559, Revision 2, dated May 13, 2014. The service information describes procedures for modifying the tension tie and frame at certain center sections, including related investigative and corrective actions; post- modification inspections for cracking of the tension tie and frame structure and corrective actions; an additional modification; an inspection of all areas of the modified tension ties for cracking; an inspection of the tension tie center section for cracking in certain tension tie channels; and repair. 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 ---------------------------------------------------------------------------------------------------------------- Retained modification in AD 2012- Between 257 and Between $341,334 Between $363,179 Between 15-13 (67 airplanes). 263 work-hours x and $345,490. and $367,845. $24,332,993 and $85 per hour = $24,645,615. between $21,845 and $22,355.

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. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. Sec. 39.13 [Amended] 0 2. The FAA amends Sec. 39.13 by removing Airworthiness Directive (AD) 2012-15-13, Amendment 39-17142 (77 FR 47267, August 8, 2012), and adding the following new AD: 2016-05-12 The Boeing Company: Amendment 39-18430; Docket No. FAA- 2015-2961; Directorate Identifier 2014-NM-145-AD. (a) Effective Date This AD is effective April 22, 2016. (b) Affected ADs This AD replaces AD 2012-15-13, Amendment 39-17142 (77 FR 47267, August 8, 2012) (``AD 2012-15-13''). (c) Applicability This AD applies to The Boeing Company Model 747-100B SUD, 747- 300, 747-400, and 747-400D series airplanes; and Model 747-200B series airplanes having a stretched upper deck; certificated in any category; excluding airplanes that have been converted to a large cargo freighter configuration. (d) Subject Air Transport Association (ATA) of America Code 53, Fuselage. (e) Unsafe Condition This AD was prompted by reports of cracked and severed tension ties, broken fasteners, and cracks in the frame, shear web, and shear ties adjacent to tension ties for the upper deck. This AD was also prompted by an evaluation by the design approval holder, [[Page 14696]] which indicated that the upper deck is subject to widespread fatigue damage. We are issuing this AD to prevent fatigue cracking of the tension ties, shear webs, and frames of the upper deck, which could result in rapid decompression and reduced structural integrity of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Retained Repetitive Stage 1 Inspections, With No Changes This paragraph restates the requirements of paragraph (g) of AD 2012-15-13, with no changes.

Modifying the frame-to-tension-tie joints at STAs 1120 through 1220 terminates the repetitive inspection requirements of paragraphs (g) and (j) of this AD, the inspection requirements of paragraph (l) of this AD, and the one- time inspection requirement of paragraph (n) of this AD. As of the effective date of this AD, only Boeing Alert Service Bulletin 747- 53A2559, Revision 2, dated May 13, 2014, may be used to accomplish the actions specified in this paragraph. (1) Where paragraph 1.E., ``Compliance,'' of Boeing Service Bulletin 747-53A2559, Revision 1, dated August 4, 2011, specifies a compliance time relative to ``the original issue date of this service bulletin,'' this AD requires compliance within the specified compliance time after September 12, 2012 (the effective date of AD 2012-15-13). (2) Where Boeing Service Bulletin 747-53A2559, Revision 1, dated August 4, 2011; or Boeing Alert Service Bulletin 747-53A2559, Revision 2, dated May 13, 2014; specifies to contact Boeing for repair instructions or additional modification requirements: Before further flight, repair the cracking or do the additional actions using a method approved in accordance with the procedures specified in paragraph (t) of this AD. (3) For Group 3 through 5, Configuration 1 airplanes identified in Boeing Alert Service Bulletin 747-53A2559, Revision 2, dated May 13, 2014: Operators may accomplish the actions required by paragraph (p) of this AD within the applicable compliance times specified in paragraph 1.E., ``Compliance'' of Boeing Alert Service Bulletin 747- 53A2559, Revision 2, dated May 13, 2014. (q) Retained Credit for Previous Actions, With No Changes This paragraph restates the credit provided by paragraph (q) of AD 2012-15-13, with no changes. This paragraph provides credit for the corresponding actions required by paragraph (p) of this AD, if those actions were done before September 12, 2012 (the effective date of AD 2012-15-13), using Boeing Alert Service Bulletin 747- 53A2559, dated January 8, 2009, which is not incorporated by reference in this AD. (r) New Repetitive Post-Modification Eddy Current Inspections Do an eddy current inspection of all areas of the modified tension ties for cracking, in accordance with Part 3 of the Accomplishment Instructions of Boeing Alert Service Bulletin 747- 53A2559, Revision 2, dated May 13, 2014.

If any crack is found, before further flight, repair the crack using a method approved in accordance with the procedures specified in paragraph (t) of this AD. If no crack is found, repeat the inspection thereafter at the intervals specified in paragraph 1.E, ``Compliance,'' of Boeing Alert Service Bulletin 747-53A2559, Revision 2, dated May 13, 2014. (s) New One-Time Surface HFEC Inspections Do a surface HFEC inspection of the tension tie center section, for cracking in the forward and aft tension tie channels between STAs 1120 through 1220, in accordance with Part 4 of the Accomplishment Instructions of Boeing Alert Service Bulletin 747- 53A2559, Revision 2, dated May 13, 2014. Do the inspection at the applicable time specified in Table 1 or Table 3 of paragraph 1.E, ``Compliance,'' of Boeing Alert Service Bulletin 747-53A2559, Revision 2, dated May 13, 2014, except where paragraph 1.E., ``Compliance,'' of Boeing Alert Service Bulletin 747-53A2559, Revision 2, dated May 13, 2014, specifies a compliance time relative to ``the Revision 2 date of this service bulletin,'' this AD requires compliance within the specified compliance time after the effective date of this AD. If any crack is found, before further flight, repair the crack using a method approved in accordance with the procedures specified in paragraph (t) of this AD. (t) Alternative Methods of Compliance (AMOCs) (1) The Manager, Seattle Aircraft Certification Office (ACO), FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.
