AD 2017-06-09

We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 787-8 airplanes. This AD was prompted by a report indicating that the fire block in the closets and video control stations, and fire blocking tape in the floor panel opening in the forward and aft main passenger cabin, might be missing on some airplanes. This AD requires installing a fire block in the closets and video control stations, as applicable, and installing fire blocking tape in the floor panel openings in the forward and aft main passenger cabin. We are issuing this AD to address the unsafe condition on these products.

Final rule.

Adoption of the Amendment \n\n\n\tAccordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: \n\nPART 39--AIRWORTHINESS DIRECTIVES \n\n0 1.

((Page 15124)) \n\nDiscussion \n\n\n\tWe 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 published in the Federal Register on August 17, 2016 (81 FR 54750) (''the NPRM''). The NPRM was prompted by a report indicating that the fire block in the closets and video control stations, and fire blocking tape in the floor panel opening in the forward and aft main passenger cabin, might be missing on some airplanes. The NPRM proposed to require installing a fire block in the closets and video control stations, as applicable, and installing fire blocking tape in the floor panel openings in the forward and aft main passenger cabin. We are issuing this AD to prevent propagation of a fire in the lower lobe cheek area outboard of a closet or video control station. Such propagation could result in an increased risk of smoke and/or fire propagation into thepassenger cabin. \n\nComments \n\n\n\tWe 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. \n\nSupport for NPRM \n\n\n\tThe Air Line Pilots Association, International indicated its support for the intent of the NPRM. \n\nRequest To Clarify the Unsafe Condition \n\n\n\tBoeing asked that we clarify certain language related to the unsafe condition throughout the NPRM. Boeing stated that the location of the unsafe condition, referred to in the NPRM as ''video control station and closets,'' should be changed to ''closets and video control stations.'' Boeing stated that closets and video control stations are two separate monument designs, and the current wording implies that the requirement applies only to monuments with video controls. \n\tWe agree with the commenter's request for the reason provided. We have clarified this language in all applicable sections of this AD. \n\nRequest To Include Later Revision of Service Information \n\n\n\tUnited Airlines (UA) asked that we include Issue 002 of Boeing Alert Service Bulletin B787-81205-SB530018-00, for accomplishing certain actions in the proposed AD. UA stated that it was informed by Boeing that Issue 002 is in work. UA noted that adding this later revision will minimize potential requests for alternative methods of compliance (AMOCs). \n\tWe do not agree with the commenter's request. We do not consider that delaying this final rule until after the release of the manufacturer's planned service information (Issue 002 of Boeing Alert Service Bulletin B787-81205-SB530018-00) is warranted. We have identified an unsafe condition and the actions specified in Boeing Alert Service Bulletin B787-81205-SB530018-00, Issue 001, dated June 7, 2013, address the unsafe condition for airplanes identified in paragraph (g)(3) of this AD. However, under the provisions of paragraph (h) of this AD, operators may request approval touse later revisions of the service information as an AMOC with this AD. We have not changed this AD in this regard. \n\nRequest To Issue Two ADs Instead of One \n\n\n\tUA asked that we split the NPRM into two ADs; one AD for Boeing Alert Service Bulletin B787-81205-SB250028-00, Issue 001, dated August 1, 2013; and Boeing Alert Service Bulletin B787-81205-SB250070-00, Issue 001, dated March 10, 2015; and one AD for Boeing Alert Service Bulletin B787-81205-SB530018-00, Issue 001, dated June 7, 2013. UA stated that although all of this service information addresses fire blocking, different areas with different procedures are specified in each service bulletin. \n\tWe do not agree with the commenter's request. We do not consider that delaying this final rule, so that the required actions can be split into two ADs based on the location of the corrective actions, is warranted. In order to address the identified unsafe condition in a timely manner, we find that we must issue this AD by mandating the specified actions described in the referenced service information. We have not changed this AD in this regard. \n\nRequest To Clarify Certain Action in the Costs of Compliance Section \n\n\n\tBoeing asked that we change the phrase ''video control closet'' to ''closet'' in the Costs of Compliance section, for clarification. Boeing stated that the referenced service information does not have a monument listing for a ''video control closet'' but lists this monument as a ''closet.'' \n\tWe agree with the commenter's request for the reason provided. We have changed this language in the Costs of Compliance section accordingly. \n\nConclusion \n\n\n\tWe 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: \n\tAre consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and \n\tDo not add any additional burden upon the public than was already proposed in the NPRM. \n\tWe also determined that these changes will not increase the economic burden on any operator or increase the scope of this AD. \n\nRelated Service Information Under 1 CFR Part 51 \n\n\n\tWe reviewed the following service information: \n\tBoeing Alert Service Bulletin B787-81205-SB250028-00, Issue 001, dated August 1, 2013. The service information describes procedures for installing a fire block in the closets and video control stations. \n\tBoeing Alert Service Bulletin B787-81205-SB250070-00, Issue 001, dated March 10, 2015. The service information describes procedures for installing a fire block in the video control station. \n\tBoeing Alert Service Bulletin B787-81205-SB530018-00, Issue 001, dated June 7, 2013. The service information describes procedures for installing fire blocking tape in the floor panel openings in the forward and aft main passenger cabin. \n\tThis 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. \n\nCosts of Compliance \n\n\n\tWe estimate that this AD affects 6 airplanes of U.S. registry. We estimate the following costs to comply with this AD: \n\n((Page 15125)) \n\n\n\n\n\n\n\tEstimated Costs ---------------------------------------------------------------------------------------------------------------- \n\tCost on U.S. \n\tAction Labor cost Parts cost Cost per product operators ---------------------------------------------------------------------------------------------------------------- Fire blocking tape installation Up to 23 work-hours $0 Up to $1,955 per Up to $11,730 per \n\tin the floor panel openings. x $85 per hour = installation. installation. \n\t$1,955 per \n\tinstallation. Fire block installation in the5 work-hours x $85 489 $914 per $5,484 per \n\tcloset. per hour = $425 installation. installation. \n\tper installation. Fire block installation in the 5 work-hours x $85 276 $701 per $4,206 per \n\tvideo control station. per hour = $425 installation. installation. \n\tper installation. ---------------------------------------------------------------------------------------------------------------- \n\n\n\tAccording 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. \n\nAuthority for This Rulemaking \n\n\n\tTitle 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. \n\tWe 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. \n\nRegulatory Findings \n\n\n\tThis 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 thevarious levels of government. \n\tFor the reasons discussed above, I certify that this AD: \n\t(1) Is not a ''significant regulatory action'' under Executive Order 12866, \n\t(2) Is not a ''significant rule'' under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979), \n\t(3) Will not affect intrastate aviation in Alaska, and \n\t(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. \n\nList of Subjects in 14 CFR Part 39 \n\n\n\tAir transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.
