[Federal Register Volume 81, Number 45 (Tuesday, March 8, 2016)] [Proposed Rules] [Pages 12039-12041] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2016-04682] [[Page 12039]] ======================================================================= ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2016-4219; Directorate Identifier 2015-NM-169-AD] RIN 2120-AA64 Airworthiness Directives; The Boeing Company Airplanes 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 airplanes. This proposed AD was prompted by reports of latently failed fuel shutoff valves discovered during fuel filter replacement. This proposed AD would require doing an inspection to identify the part number of the engine fuel spar motor- operated valve (MOV) actuators; replacing certain MOV actuators with new MOV actuators on both airline information management system (AIMS) V1 and V2 equipped airplanes, or installing a newer software version on AIMS V2 equipped airplanes. We are proposing this AD to prevent latent failure of the fuel shutoff valve to the engine. This valve failure, if not prevented, could result in the inability to terminate fuel flow to the engine, which in case of an engine fire, could lead to wing failure. DATES: We must receive comments on this proposed AD by April 22, 2016. ADDRESSES: You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods:Federal eRulemaking Portal: Go to http://www.regulations.gov.

We will consider all comments received by the closing date and may amend this proposed AD because of those comments. We 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 proposed AD. Discussion We have received reports of latently failed fuel shutoff valves discovered during fuel filter replacement. Deficiencies in the valve actuator design have resulted in latent failures of the fuel shutoff valve to the engine. This condition, if not prevented, could result in the inability to terminate fuel flow to the engine, which in case of an engine fire, could lead to wing failure. We have previously determined that operators should not be required to replace the two fuel spar valve actuators with new actuators when we previously mandated replacement of MOV actuators for other valve positions in AD 2013-05-03, Amendment 39-17375 (78 FR 17290, March 21, 2013). The alternate MOV actuator configurations available at that time were discovered to be susceptible to latent failures that could result in the inability to shut-off fuel to the engine. We are proposing this AD because a new MOV actuator has become available which corrects the latent failure of an MOV actuator. We have excluded line numbers 1165 and subsequent from the applicability section of this proposed AD as these airplanes were manufactured new with AIMS-2 Blockpoint Version 17 or higher installed, which are not affected by the unsafe condition. Related Rulemaking AD 2013-05-03, Amendment 39-17375 (78 FR 17290, March 21, 2013), for certain The Boeing Company Model 777-200, -200LR, -300, and -300ER series airplanes, requires replacing MOV actuators having part number (P/N) MA20A1001-1 with certain new or serviceable MOV actuators; and measuring the electrical resistance of the bond from the adapter plate to the airplane structure, and doing corrective actions if necessary. AD 2015-19-01, Amendment 39-18264 (80 FR 55521, September 16, 2015), for certain The Boeing Company Model 777 airplanes, requires revising the maintenance or inspection program to add Airworthiness Limitation (AWL) 28-AWL-MOV for an engine fuel shutoff valve (fuel spar valve) actuator inspection. On October 30, 2014, we issued an NPRM, Docket No. FAA-2014-0755, Directorate Identifier 2014-NM-080-AD (79 FR 66343, November 7, 2014), for all The Boeing Company Model 737-600, -700, -700C, 800, -900, and - 900ER series airplanes, Model 757 airplanes, Model 767 airplanes, and Model 777 airplanes, which would require replacement of any spar- mounted MOV actuator having P/N MA20A1001-1 (S343T003 39) for the fuel tanks or fuel feed system with a serviceable, FAA-approved MOV actuator. Related Service Information Under 1 CFR Part 51 We reviewed Boeing Service Bulletin 777-28A0034, Revision 3, dated [[Page 12040]] September 25, 2015. This service information describes procedures for, among other things, inspection and replacement of the main and center fuel tank valve actuators. We also reviewed Boeing Service Bulletin 777-31-0227, Revision 1, dated August 12, 2015. This service information describes procedures for installing the AIMS 2, Blockpoint Version 17, software upgrade. 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 an inspection to determine the part numbers of installed engine fuel spar MOV actuators; for certain airplanes, replacement of certain MOV actuators with new MOV actuators having part number (P/N) MA30A1017; and for certain other airplanes, replacement of certain MOV actuators with new MOV actuators having P/N MA30A1017, or installation of a certain version of the airplane information management system (AIMS) software; using the Accomplishment Instructions in the service information described previously. For information on the procedures, see this service information at http://www.regulations.gov by searching for and locating Docket No. FAA-2016- 4219. Costs of Compliance We estimate that this proposed AD affects 154 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: Estimated Costs ---------------------------------------------------------------------------------------------------------------- Cost per Cost on U.S. Action Labor cost Parts cost product operators ---------------------------------------------------------------------------------------------------------------- Inspection............................ 1 work-hour X $85 per $0 $85 $13,090. (154 airplanes)....................... hour = $85. Replacement of two actuators without 5 work-hours X $85 per 12,000 12,425 422,450. fuel tank access. hour = $425. (34 airplanes)........................ AIMS 2, Blockpoint Version 17, 7 work-hours X $85 per 0 595 71,400. installation. hour = $595. (120 airplanes)....................... ---------------------------------------------------------------------------------------------------------------- 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. 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39--AIRWORTHINESS DIRECTIVES 0 1.
