2018-02199. Airworthiness Directives; The Boeing Company Airplanes  

  • Start Preamble Start Printed Page 5741

    AGENCY:

    Federal Aviation Administration (FAA), DOT.

    ACTION:

    Notice of proposed rulemaking (NPRM).

    SUMMARY:

    We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 787 series airplanes. This proposed AD was prompted by reports that, under certain conditions, the automatic dependent surveillance—broadcast (ADS-B) out function and air traffic control/traffic alert and collision avoidance system (ATC/TCAS) functions can transmit incorrect data. This proposed AD would require an inspection or records review to determine if certain software is installed, the installation of new software for the integrated surveillance system (ISS) operational program software (OPS) if necessary, a software check, and applicable on-condition actions. For certain airplanes, this proposed AD would also require the installation of new software for the ISS OPS and the displays and crew alerting (DCA) database. We are proposing this AD to address the unsafe condition on these products.

    DATES:

    We must receive comments on this proposed AD by March 26, 2018.

    Discussion

    We have received reports indicating that the ADS-B out function and ATC/TCAS functions can transmit incorrect position and pressure altitude information in the data that is used by ATC to coordinate aircraft separation. Under certain conditions, the ADS-B out function has been shown to transmit non-current aircraft data (including latitude, longitude, and pressure altitude) based on coasting from a previous global positioning system (GPS) position. In addition, the ATC/TCAS functions can transmit non-current pressure altitude information on both mode C and mode S transmissions based on coasting from a previous pressure altitude. This condition, if not corrected, could result in potential mid-air collisions.

    Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Alert Service Bulletin B787-81205-SB340036-00, Issue 001, dated June 30, 2017. This service information describes procedures for the installation of new software for the ISS OPS (which includes main input/output (IO) software and traffic transponder (XPDR) airborne collision avoidance system (ACAS) software), a software check, and applicable on-condition actions.

    We also reviewed Boeing Service Bulletin B787-81205-SB340005-00, Issue 002, dated April 27, 2016. This service information describes procedures for the installation of new software for the ISS OPS and for the DCA database.

    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 these same type designs.

    Proposed AD Requirements

    This proposed AD would require, for certain airplanes, an inspection or records review to determine if certain software is installed, and if necessary, accomplishment of the actions identified as “RC” (required for compliance) in the Accomplishment Instructions of Boeing Alert Service Bulletin B787-81205-SB340036-00, Issue 001, dated June 30, 2017, described previously, except for any differences identified as exceptions in the regulatory text of this proposed AD.

    This proposed AD would also require, for certain airplanes, accomplishing the actions specified in Boeing Service Bulletin B787-81205-SB340005-00, Issue 002, dated April 27, 2016, described previously.

    For information on the procedures and compliance times, see this service information at http://Start Printed Page 5742www.regulations.gov by searching for and locating Docket No. FAA-2018-0027.

    Differences Between Proposed AD and the Service Information

    The effectivity of Boeing Alert Service Bulletin B787-81205-SB340036-00, Issue 001, dated June 30, 2017, and Boeing Service Bulletin B787-81205-SB340005-00, Issue 002, dated April 27, 2016, is limited to Model 787-8 and 787-9 airplanes with certain line numbers. However, the applicability of this proposed AD includes all Boeing Model 787 series airplanes, because the affected software part numbers, identified in paragraph (j) of this proposed AD, are rotable parts. We have determined that these part numbers could later be installed on airplanes that were initially delivered with acceptable software, thereby subjecting those airplanes to the unsafe condition.

    Costs of Compliance

    We estimate that this proposed AD affects 136 airplanes of U.S. registry. We also estimate that 115 airplanes will require installation and check of new software, and 54 airplanes will require the concurrent installation of other software. 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
    Records Review/Inspection (136 airplanes)1 work-hour × $85 per hour = $85$0$85$11,560
    Installation and Check (115 airplanes)4 work-hours × $85 per hour = $340034039,100
    Concurrent Installation (54 airplanes)1 work-hour × $85 per hour = $850854,590

    We estimate the following costs to do any necessary on-condition actions that would be required. We have no way of determining the number of aircraft that might need these on-condition actions:

    Estimated Costs of On-Condition Actions

    Labor costParts costCost per product
    4 work-hours × $85 per hour = $340$0$340

    According to the manufacturer, some 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 available 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.

    (j) Parts Installation Prohibition

    As of the effective date of this AD, no person may install ISS OPS part number COL40-0010-0100 or COL46-0007-0100 on any airplane, except in accomplishment of the actions required by paragraph (i) of this AD.

    (k) Credit for Previous Actions

    This paragraph provides credit for the actions specified in paragraph (i) of this AD, if those actions were performed before the effective date of this AD using Boeing Service Bulletin B787-81205-SB340005-00, Issue 001, dated December 11, 2015.

    (l) 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 (m)(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, 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 (l)(4)(i) and (l)(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.
