2018-14425. Airworthiness Directives; The Boeing Company Airplanes  

  • Start Preamble

    AGENCY:

    Federal Aviation Administration (FAA), DOT.

    ACTION:

    Notice of proposed rulemaking (NPRM).

    SUMMARY:

    We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 777-200, -200LR, -300, and -300ER series airplanes. This proposed AD was prompted by a report that showed a non-compliance exists on some in-service galley attendant seat fitting installations. The non-compliance could result in flight attendant seats failing in a high-G crash. This proposed AD would require modifications for galley mounted seat fittings. We are proposing this AD to address the unsafe condition on these products.

    Discussion

    We have received a report that showed a non-compliance exists on some in-service galley attendant seat fitting installations. This condition, if not addressed, could result in flight attendant seats failing in a high-G crash, resulting in potential injury to flight attendants and consequent inability of the flight attendants to assist with passenger evacuation in a timely manner.

    Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Special Attention Service Bulletin 777-25-0649, Revision 1, dated October 6, 2017. The service information describes procedures for modifications for galley mounted seat fittings. 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.

    FAA's Determination

    We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design.

    Proposed AD Requirements

    This proposed AD would require accomplishment of the actions identified as “RC” (required for compliance) in the Accomplishment Instructions of Boeing Special Attention Service Bulletin 777-25-0649, Revision 1, dated October 6, 2017, described previously, except as discussed under “Differences Between this Proposed AD and the Service Information,” and except for any differences identified as exceptions in the regulatory text of this proposed AD.

    For information on the procedures and compliance times, see this service information at http://www.regulations.gov by searching for and locating Docket No. FAA-2018-0581.

    Differences Between This Proposed AD and the Service Information

    Boeing Special Attention Service Bulletin 777-25-0649, Revision 1, dated October 6, 2017, specifies the compliance time as 1,875 days. For this proposed AD, we specified the compliance time as 6 years. We have coordinated this difference with Boeing.

    Costs of Compliance

    We estimate that this proposed AD affects 50 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD:

    Estimated Costs for Required Actions

    ActionLabor costParts costCost per productCost on U.S. operators
    Modification7 work-hours × $85 per hour = $595$0$595$29,750

    According to the manufacturer, some or all of the costs of this proposed 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 known costs in our cost estimate.

    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 proposed 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 delegated the authority to issue ADs applicable to transport category airplanes to the Director of the System Oversight Division.

    Regulatory Findings

    We determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 this proposed regulation:

    (1) Is not a “significant regulatory action” under Executive Order 12866,

    (2) Is not a “significant rule” under the 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.

    The Boeing Company: Docket No. FAA-2018-0581; Product Identifier 2018-NM-029-AD.

    (a) Comments Due Date

    We must receive comments by August 20, 2018.

    (b) Affected ADs

    None.

    (c) Applicability

    This AD applies to The Boeing Company Model 777-200, -200LR, -300, and -300ER series airplanes, certificated in any category, as identified in Boeing Special Attention Service Bulletin 777-25-0649, Revision 1, dated October 6, 2017.

    (d) Subject

    Air Transport Association (ATA) of America Code 25, Equipment/furnishings.

    (e) Unsafe Condition

    This AD was prompted by a report that showed a non-compliance exists on some in-service galley attendant seat fitting installations. The non-compliance could result in flight attendant seats failing in a high-G crash. We are issuing this AD to address non-compliant flight attendant seats, which could fail in a high-G crash and result in potential injury to flight attendants and consequent inability of the flight attendants to assist with passenger evacuation in a timely manner.

    (f) Compliance

    Comply with this AD within the compliance times specified, unless already done.

    (g) Required Actions

    Within 6 years after the effective date of this AD, do all applicable actions identified as “RC” (required for compliance) in, and in accordance with, the Accomplishment Instructions of Boeing Special Attention Service Bulletin 777-25-0649, Revision 1, dated October 6, 2017.

    (h) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Seattle ACO Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request to your principal inspector or local Flight Standards District Office, as appropriate. If sending information directly to the manager of the certification office, send it to the attention of the person identified in paragraph (i)(1) of this AD. Information may be emailed to: 9-ANM-Seattle-ACO-AMOC-Requests@faa.gov.

    (2) Before using any approved AMOC, notify your appropriate principal inspector, or lacking a principal inspector, the manager of the local flight standards district office/certificate holding district office.

    (3) An AMOC that provides an acceptable level of safety may be used for any repair, modification, or alteration required by this AD if it is approved by the Boeing Commercial Airplanes Organization Designation Authorization (ODA) that has been authorized by the Manager, Seattle ACO Branch, FAA, to make those findings. To be approved, the repair method, modification deviation, or alteration deviation must meet the certification basis of the airplane, and the approval must specifically refer to this AD.

    (4) For service information that contains steps that are labeled as RC, the provisions of paragraphs (h)(4)(i) and (h)(4)(ii) of this AD apply.

    (i) The steps labeled as RC, including substeps under an RC step and any figures identified in an RC step, must be done to comply with the AD. If a step or substep is labeled “RC Exempt,” then the RC requirement is removed from that step or substep. An AMOC is required for any deviations to RC steps, including substeps and identified figures.

    (ii) Steps not labeled as RC may be deviated from using accepted methods in accordance with the operator's maintenance or inspection program without obtaining approval of an AMOC, provided the RC steps, including substeps and identified figures, can still be done as specified, and the airplane can be put back in an airworthy condition.
