[Federal Register Volume 81, Number 170 (Thursday, September 1, 2016)] [Rules and Regulations] [Pages 60248-60252] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2016-20825] ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2016-3702; Directorate Identifier 2015-NM-103-AD; Amendment 39-18634; AD 2016-18-04] 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) 2013-24-12 for all The Boeing Company Model 747-8 and 747-8F airplanes. AD 2013-24-12 required repetitive ultrasonic or dye penetrant inspections for cracking of the barrel nuts and bolts on each forward engine mount, and related investigative and corrective actions if necessary. This new AD retains the requirements of AD 2013-24-12 and also requires installing new barrel nuts at the forward engine mounts; or identifying the part number of the barrel nuts, inspecting affected barrel nuts for gaps of the strut bulkhead and forward engine mount, and doing related investigative and corrective actions if necessary. This new AD also removes airplanes from the applicability. This new AD also requires revising the maintenance or inspection program, as applicable, to include a new structurally significant item. This AD was prompted by our determination that it is necessary to mandate the installation of new barrel nuts or new inspections to adequately address the unsafe condition. We are issuing this AD to detect and correct cracked barrel nuts on a forward engine mount, which could result in reduced load capacity of the forward engine mount, separation of an engine under power from the airplane, and consequent loss of control of the airplane. DATES: This AD is effective October 6, 2016. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of October 6, 2016. The Director of the Federal Register approved the incorporation by reference of a certain other publication listed in this AD as of December 17, 2013 (78 FR 71989, December 2, 2013).

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2013-24-12, Amendment 39-17686 (78 FR 71989, December 2, 2013) (``AD 2013-24-12''). AD 2013-24-12 applied to all The Boeing Company Model 747-8 and 747-8F airplanes. The NPRM published in the Federal Register on February 25, 2016 (81 FR 9370) (``the NPRM''). The NPRM was prompted by our determination that it is necessary to mandate the installation of new barrel nuts or new inspections to adequately address the unsafe condition. The NPRM proposed to retain the requirements of AD 2013-24-12 and also require installing new barrel nuts at the forward engine mounts; or identifying the part number of the barrel nuts, inspecting affected barrel nuts for gaps of the strut bulkhead and forward engine mount, and doing related investigative and corrective actions if necessary. The NPRM also proposed to remove airplanes from the applicability. The NPRM also proposed to require revising the maintenance or inspection program, as applicable, to include a new structurally significant item. We are issuing this AD to detect and correct cracked barrel nuts on a forward engine mount, which could result in reduced load capacity of the forward engine mount, separation of an engine under power from the airplane, and consequent loss of control 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 Boeing stated that it supports the NPRM. Request To Revise Applicability The Civil Aviation Administration of China (CAAC) requested that we revise the applicability of the proposed AD to ensure that all necessary actions are applied on all applicable airplanes. CAAC explained that it compared the effectivity between Boeing Service Bulletin 747-71A2329, Revision 1, dated May 28, 2015, which is referred to in the applicability of the proposed AD, and Boeing Special Attention Service Bulletin 747-71-2332, Revision 1, dated May 28, 2015 (which is referred to as the appropriate source of service information for doing the actions specified in paragraph (k) of the proposed AD). CAAC explained that there are more airplanes in Boeing Special Attention Service Bulletin 747-71-2332, Revision 1, dated May 28, 2015, than in Boeing Service Bulletin 747-71A2329, Revision 1, dated May 28, 2015. We agree to clarify and revise the applicability of this AD. The difference in effectivity between Boeing Service Bulletin 747-71A2329, Revision 1, dated May 28, 2015, and Boeing Special Attention Service Bulletin 747-71-2332, Revision 1, dated May 28, 2015, [[Page 60249]] is that there are six additional airplanes in Boeing Special Attention Service Bulletin 747-71-2332, Revision 1, dated May 28, 2015--four of these airplanes are foreign-registered, and the other two airplanes have not been delivered yet. We have revised paragraph (c) of this AD to refer to Boeing Special Attention Service Bulletin 747-71-2332, Revision 1, dated May 28, 2015. We have also revised paragraph (g) of this AD to specify that only airplanes identified in Boeing Service Bulletin 747-71A2329, Revision 1, dated May 28, 2015, are affected by that paragraph. Request for Explanation of Change in Applicability From AD 2013-24-12 The CAAC requested that we explain the change in the applicability paragraph of the proposed AD from that of AD 2013-24-12. The CAAC explained that the applicability paragraph of AD 2013-24-12 applies to all The Boeing Company Model 747-8 and 747-8F series airplanes. The CAAC stated that the NPRM would retain the requirements of AD 2013-24- 12, but the applicability paragraph of the proposed AD only applies to The Boeing Company Model 747-8 and 747-8F airplanes identified in Boeing Service Bulletin 747-71A2329, Revision 1, dated May 28, 2015. We agree to clarify. AD 2013-24-12 was issued as an interim action. Boeing developed Boeing Special Attention Service Bulletin 747-71-2332, dated September 27, 2013 (currently at Revision 1, dated May 28, 2015), which contains a newly designed barrel nut. The effectivity in Boeing Service Bulletin 747-71A2329, Revision 1, dated May 28, 2015, identifies the airplanes that did not have the newly designed barrel nuts installed upon delivery. Because this AD does not include airplanes that have the newly designed barrel nuts installed during production, the applicability of AD 2013-24-12 was reduced. No changes have been made to 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 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 the following service information: Boeing Service Bulletin 747-71A2329, Revision 1, dated May 28, 2015. The service information describes procedures for inspecting for cracked bolts and barrel nuts on the forward engine mounts, replacing cracked bolts and barrel nuts, and sending the inspection results and cracked parts to Boeing. Boeing Special Attention Service Bulletin 747-71-2332, Revision 1, dated May 28, 2015. The service information describes procedures for installing new barrel nuts, inspecting the barrel nuts at the forward engine mount to determine the part number, inspecting for gaps of the strut bulkhead and forward engine mount, and doing applicable related investigative and corrective actions. Boeing 747-8/-8F Airworthiness Limitations (AWLs), Document Number D011U721-02-01, dated September 2015, which includes a limitation for Structurally Significant Item (SSI) 54-50-003c. The service information describes procedures for structural inspections. 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 7 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 ---------------------------------------------------------------------------------------------------------------- Inspections (retained actions Up to 24 work-hours x $0 Up to $2,040 per Up to $14,280 per from AD 2013-24-12). $85 per hour = $2,040 inspection cycle. inspection cycle. per inspection cycle. Installation (new action)...... 17 work-hours x $85 per 6,384 7,829............. Up to $54,803. hour = $1,445. Inspections (new alternative 4 work-hours x $85 per 0 340............... Up to $2,380. actions). hour = $340. Maintenance program revision 1 work-hour x $85 per 0 85................ 595. (new requirement). hour = $85. ---------------------------------------------------------------------------------------------------------------- We have received no definitive data that would enable us to provide cost estimates for the bootstrap installation specified in this AD. We estimate the following costs to do other necessary related investigative and corrective actions that would be required based on the results of the inspection. We have no way of determining the number of aircraft that might need these actions: On-Condition Costs ---------------------------------------------------------------------------------------------------------------- Cost per Action Labor cost Parts cost product ---------------------------------------------------------------------------------------------------------------- Ultrasonic inspection..................... 5 work-hours x $85 per hour = $425 $0 $425 ---------------------------------------------------------------------------------------------------------------- According to the manufacturer, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate. Paperwork Reduction Act A federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject [[Page 60250]] to penalty for failure to comply with a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a current valid OMB control number. The control number for the collection of information required by this AD is 2120-0056. The paperwork cost associated with this AD has been detailed in the Costs of Compliance section of this document and includes time for reviewing instructions, as well as completing and reviewing the collection of information. Therefore, all reporting associated with this AD is mandatory. Comments concerning the accuracy of this burden and suggestions for reducing the burden should be directed to the FAA at 800 Independence Ave. SW., Washington, DC 20591, ATTN: Information Collection Clearance Officer, AES-200. 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.
