[Federal Register Volume 83, Number 108 (Tuesday, June 5, 2018)] [Rules and Regulations] [Pages 25894-25898] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2018-11816] ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2017-0779; Product Identifier 2017-NM-040-AD; Amendment 39-19301; AD 2018-11-13] RIN 2120-AA64 Airworthiness Directives; The Boeing Company Airplanes AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 787-8 airplanes. This AD was prompted by a report of possible degraded bond-line performance of co-bonded upper wing stringer-to-skin joints. This AD requires repetitive inspections of certain upper wing stringers for any disbond and corrective actions, if necessary; and a terminating preventive modification of installing disbond arrestment (DBA) fasteners. This AD also requires revising the inspection or maintenance program to incorporate an airworthiness limitation. We are issuing this AD to address the unsafe condition on these products. DATES: This AD is effective July 10, 2018. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of July 10, 2018.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain The Boeing Company Model 787-8 airplanes. The NPRM was published in the Federal Register on August 25, 2017 (82 FR 40511). The NPRM was prompted by a report of possible degraded bond-line performance of co-bonded upper wing stringer-to-skin joints. The NPRM proposed to require repetitive inspections of certain upper wing stringers for any disbond, and corrective actions if necessary; and a terminating preventive modification of installing DBA fasteners. The NPRM also proposed to require revising the inspection or maintenance program to incorporate an airworthiness limitation. The degraded stringer bond-line does not meet the residual strength requirements if an adjacent stringer becomes disbonded due to induced damage at a critical location. We are issuing this AD to prevent upper wing stringer-to-skin joint disbonding, which can reduce the structural integrity of the airplane. Comments We gave the public the opportunity to participate in developing this final rule. The following presents the comments received on the NPRM and the FAA's response to each comment. Support for the NPRM One commenter, Ken Mayes, and United Airlines (UAL) expressed support for the NPRM. Request To Specify Updated Service Information UAL, Japan Airlines (JAL), All Nippon Airways (ANA), and Boeing requested that we specify a later revision of the service information. Boeing pointed out that Issue 002 of Boeing Alert Service Bulletin B787-81205-SB570030-00 is expected to be released in the first half of 2018. JAL pointed out that Boeing has released Information Notice B787- 81205-SB570030-00 IN-01, dated April 5, 2017, to include a certain special tool. JAL mentioned communications with Boeing regarding ``location 2'' fasteners that are for the dry bay installation and part of the basic design features. JAL also mentioned that Boeing communicated that certain specifications for ultraviolet protections were not the latest revisions in Boeing Alert Service Bulletin B787- 81205-SB570030-00, Issue 001, dated March 17, 2017. JAL specifically mentioned its preference to avoid deviations based on these issues. UAL specified that seven airplanes from the UAL fleet are affected by the NPRM. ANA pointed out that Issue 002 of Boeing Alert Service Bulletin B787-81205-SB570030-00 is expected to include alternative non- destructive test (NDT) procedures, alternative cleaning procedures, additional removal and installation specifications, and alternative special tools. ANA also pointed out that certain details regarding the new copper foils are incorrect in Issue 001 of the service information and that Issue 002 will correct those inaccuracies. We do not consider that delaying this action until release of the planned service bulletin is warranted. Issue 002 of Boeing Alert Service Bulletin B787-81205-SB570030-00 is not yet approved, and we cannot specify future revisions of service information in this AD. Boeing Alert Service Bulletin B787-81205-SB570030-00, Issue 001, dated March 17, 2017, is the currently available revision, and it provides adequate information to address the identified unsafe condition. We have not reviewed the proposed Issue 002 of Boeing Alert Service Bulletin B787-81205-SB570030-00. However, the proposed Issue 002 of Boeing Alert Service Bulletin B787-81205-SB570030-00, is expected to provide more options, clarifications, and corrections, which may be helpful, but are not necessary to accomplish the requirements of this AD. These revisions are not expected to affect an operator's ability to comply with this AD. Therefore, we do not plan to wait for the release of Issue 002 of Boeing Alert Service Bulletin B787-81205-SB570030-00 before issuing this AD. However, we will consider requests for approval of an alternative method of compliance (AMOC) to allow the use of Issue 002 of Boeing Alert Service Bulletin B787-81205-SB570030-00 after it has been published, under the provisions of paragraph (l) of this AD. We have not changed this final rule regarding this issue. Request To Clarify Information Leading to AD Action Boeing requested that we clarify the information leading to the AD action in the SUMMARY of the NPRM and paragraph (e) of the proposed AD. The commenter pointed out that Boeing notified the FAA of possible degraded bond-line performance, but that there have been no reports of stringer disbonds found in the fleet. We agree for the reasons provided. We have revised the SUMMARY section of this final rule and paragraph (e) of this AD to specify that this AD was prompted by a report of possible degraded bond-line performance of co-bonded upper wing stringer-to-skin joints. Request To Clarify the Cause of the Possible Degraded Bond-Line Performance Boeing requested that we clarify the cause of the possible degraded bond-line performance. The commenter pointed out that a specific type of Boeing Material Specification (BMS) 8-308 peel ply, and exposure to cure times that exceeded 4 hours at a temperature of 355 Fahrenheit degrees (10 Fahrenheit degrees), are contributing factors. The commenter also pointed out that other types of BMS 8-308 peel ply are not affected by the unsafe condition. The commenter also mentioned that the temperature specified (345 Fahrenheit degrees ( 10 Fahrenheit degrees)) in Boeing Alert Service Bulletin 787-81205- SB570030-00, Issue 001, dated March 17, 2017, in the description of the incident was incorrect. We agree that clarification is necessary, in that, the BMS 8-308 specification includes multiple different types of peel ply material, and not all BMS 8-308 material types are affected by this AD. In fact, the replacement peel ply material specified in the service information was also selected from the BMS 8-308 specification. However, we do not agree to specify the temperature in this AD, because that information is not restated in the final rule. We have not changed this final rule regarding this issue. Request To Clarify the Condition That Could Cause the Unsafe Condition Boeing requested that we revise the Discussion section of the NPRM to clarify the condition that could cause the unsafe condition. The commenter pointed out that the upper wing stringer-to-skin joint may not sustain limit load if a stringer has a one-bay [[Page 25896]] disbond and is adjacent to a critical stringer with a degraded bond- line, which could adversely affect the structural integrity of the airplane. The commenter also pointed out that the degraded bond-lines are good for ultimate load and long-term durability when not assuming an adjacent stringer disbond. The commenter stated that the only way to show less than limit load capability is to assume that the degraded bond-line is adjacent to a one-bay disbond. We agree that clarification is necessary, in that, the unsafe condition is a residual strength requirement that assumes an already damaged structure. We have revised the Discussion section of this final rule to reflect this condition. Request To Clarify ``Assumed'' Conditions of Unsafe Condition Boeing requested that we revise the NPRM to specify that the unsafe condition is based on additional assumed conditions. The commenter stated that the NPRM would not prevent anything, as the structure is good for ultimate static and fatigue, but would ensure that no ``assumed'' disbonds could be adjacent to a degraded bond-line. We disagree with the request to revise paragraph (e) of this AD. This AD mandates inspections and provides a terminating action for airplanes with a known manufacturing non-conformance, which, under certain conditions, could reduce the structural capability of the airframe to less than limit load. We have not changed this final rule regarding this issue. Request To Specify That the Unsafe Condition Does Not Develop Boeing requested that we revise the ``FAA's Determination'' section of the NPRM to specify that while the unsafe condition could exist, it cannot develop. The commenter pointed out that the unsafe condition is a function of fabrication and not durability issues. We disagree to make the requested wording change. The ``FAA's Determination'' section of the NPRM is not restated in the final rule. We have not changed this final rule regarding this issue. Conclusion We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this final rule 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 addressing 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 final rule. Related Service Information Under 1 CFR Part 51 We reviewed Boeing Alert Service Bulletin B787-81205-SB570030-00, Issue 001, dated March 17, 2017. The service information describes procedures for inspection of certain upper wing stringers for any disbond and corrective actions; and for a preventive modification which consists of, depending on airplane configuration, applying copper foil to the upper wing at certain stringer and rib bay locations, installing DBA fasteners on the upper flanges of the upper wing stringers at the stringer and rib bay locations, applying cap seals to the DBA fasteners, and applying edge sealant to the stringers at the DBA fastener installation locations. We have also reviewed Airworthiness Limitation (AWL) 57-AWL-13, ``Inspection Requirements for In-Tank Fasteners and Edge Seal near Disbond Arrestment (DBA) Fastener Installations in Lightning Zone 2,'' of Boeing 787 Special Compliance Items/Airworthiness Limitations, D011Z009-03-04, dated February 2017. This service information describes tasks for inspecting in-tank fasteners and edge seals near DBA fastener installations of lightning zone 2. 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 24 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 ---------------------------------------------------------------------------------------------------------------- Inspection..................... 49 work-hours x $85 per $0 $4,165 per $99,960 per hour = $4,165 per inspection cycle. inspection cycle. inspection cycle. Modification................... Up to 352 work-hour x 1,902 Up to $31,822..... Up to $763,728. $85 per hour = $29,920. Maintenance or Inspection 1 work-hour x $85 per 0 $85............... $2,040. Program Revision. hour = $85. ---------------------------------------------------------------------------------------------------------------- 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. This AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has [[Page 25897]] delegated the authority to issue ADs applicable to transport category airplanes and associated appliances to the Director of the System Oversight Division. Regulatory Findings 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.
