AD 2013-15-07

We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 787-8 airplanes. This AD requires either removal or inspection of the Honeywell fixed emergency locator transmitter (ELT), and corrective action if necessary. This AD was prompted by a report of a fire involving a Honeywell fixed ELT. We are issuing this AD to prevent a fire in the aft crown of the airplane, or to detect and correct discrepancies within the ELT that could cause such a fire.

Final rule; request for comments.

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.

If sending information directly to the manager of the ACO, send it to the attention of the person identified in the Related Information section of this AD. Information may be emailed to: 9-ANM-Seattle-ACO-AMOC-Requests@faa.gov. \n\t(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. \n\n(i) Related Information \n\n\n\tFor more information about this AD, contact Kenneth Fairhurst, Senior Aerospace Engineer, Systems and Equipment Branch, ANM-130S, FAA, Seattle Aircraft Certification Office (ACO), 1601 Lind Avenue SW., Renton, Washington 98057-3356; phone: 425-917-6466; fax: 425- 917-6590; email: Kenneth.Fairhurst@faa.gov. \n\n(j) Material Incorporated by Reference \n\n\n\tNone.

Discussion \n\n\n\tWe have received a report of a fire involving the Honeywell fixed emergency locator transmitter (ELT) on a Model 787-8 airplane. The investigation indicates that the ELT may have initiated the event. Discrepancies within the ELT, if not corrected, could cause a fire in the aft crown of the airplane. \n\nFAA's Determination \n\n\n\tWe are issuing 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. \n\nAD Requirements \n\n\n\tThis AD requires either removing the Honeywell fixed ELT, or inspecting the ELT (for discrepancies associated with the ELT, ELT battery, and associated wiring), and doing corrective action if necessary, in accordance with a method approved by the FAA. \n\tThe applicability of this AD is limited to in-service airplanes, which have been delivered with Honeywell fixed ELTs having part number 1152682-2. Future production airplanes will be addressed prior to delivery. \n\tWe recognize that various civil aviation authorities (CAA) have different operational requirements regarding the use of ELTs. While the United States does not require a fixed ELT to be installed for operation, operation of an airplane without an ELT in a particular country's airspace may require coordination with that country's CAA. \n\nInterim Action \n\n\n\tThis AD is considered to be interim action. Because the fire occurred on a Model 787-8 airplane, required actions in this AD are focused on Honeywell fixed ELTs installed on that model. However, we acknowledge that ELTs are installed on various other aircraft; therefore, continued investigation is required. Once final action has been identified, we might consider further rulemaking. \n\nFAA's Justification and Determination of the Effective Date \n\n\n\tAn unsafe condition exists that requires the immediate adoption of this AD. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because discrepancies within the Honeywell fixed ELT could cause a fire in the aft crown of the airplane. Therefore, we find that notice and opportunity for prior public comment are impracticable and that good cause exists for making this amendment effective in less than 30 days. \n\nComments Invited \n\n\n\tThis AD is a final rule that involves requirements affecting flight safety and was not preceded by notice and an opportunity for public comment. However, we invite you to send any written data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include the docket number FAA-2013-0628 and Directorate Identifier 2013-NM-132-AD at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD because of those comments. \n\tWe will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this AD. \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 45055)) \n\n\n\n\n\n\n\tEstimated Costs ---------------------------------------------------------------------------------------------------------------- \n\tCost per Cost on U.S. \n\tAction Labor cost Parts cost product operators ---------------------------------------------------------------------------------------------------------------- Removal or inspection.......... 1 work-hour x $85 per hour = $0 $85 $510 \n\t$85. ---------------------------------------------------------------------------------------------------------------- \n\n\n\tWe have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in this AD. \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 islikely 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 the various 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, Incorporationby reference, Safety.
