AD 2013-25-02

We are superseding Airworthiness Directive (AD) 2000-11-06 for certain The Boeing Company Model 767 airplanes. AD 2000-11-06 required repetitive inspections to detect discrepancies of the wiring and surrounding Teflon sleeves of the fuel tank boost pumps and override/ jettison pumps; replacement of the sleeves with new sleeves, for certain airplanes; and repair or replacement of the wiring and sleeves with new parts, as necessary. This new AD requires reducing the initial compliance time and repetitive inspection interval in AD 2000-11-06; mandates a terminating action for the repetitive inspections to eliminate wire damage; removes certain airplanes from the applicability; and requires revising the maintenance program to incorporate changes to the airworthiness limitations section. This AD was prompted by fleet information indicating that the repetitive inspection interval in AD 2000-11-06 is too long, because excessive chafing of the sleeving continues to occur much earlierthan expected between scheduled inspections. We are issuing this AD to detect and correct chafing of the fuel pump wire insulation and consequent exposure of the electrical conductor, which could result in electrical arcing between the wires and conduit and consequent fire or explosion of the fuel tank.

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. The authority citation for part 39 continues to read as follows: \n\n\n\tAuthority: 49 U.S.C. 106(g), 40113, 44701. \n\n\n\nSec. 39.13 (Amended) \n\n0 2. The FAA amends Sec. 39.13 by removing Airworthiness Directive (AD) 2000-11-06, Amendment 39-11754 (65 FR 34928, June 1, 2000; corrected August 1, 2000 (65 FR 46862)), and adding the following new AD: \n\n2013-25-02 The Boeing Company: Amendment 39-17698; Docket No. FAA- 2010-1160; Directorate Identifier 2010-NM-148-AD. \n\n(a) Effective Date \n\n\n\tThis AD is effective June 5, 2014. \n\n(b) Affected ADs \n\n\n\tThis AD supersedes AD 2000-11-06, Amendment 39-11754 (65 FR 34928, June 1, 2000; corrected August 1, 2000 (65 FR 46862)). \n\n(c) Applicability \n\n\n\t(1) This AD applies to The Boeing Company Model 767-200, -300, - 300F, and -400ER series airplanes, certificated in any category, as identified in Boeing Service Bulletin 767-28A0053, Revision 3, dated November 11, 2011. \n\t(2) This AD requires revisions to certain operator maintenance documents to include new actions (e.g., inspections). Compliance with these actions is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by this AD, the operator may not be able to accomplish the actions described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval for an alternative method of compliance according to paragraph (p) of this AD. The request should include a description of changes to the required actions that will ensure the continued operational safety of the airplane. \n\n(d) Subject \n\n\n\tAir Transport Association (ATA) of America Code 28: Fuel. \n\n(e) Unsafe Condition \n\n\n\tThis AD was prompted by fleet information indicating that the repetitive inspection interval in AD 2000-11-06, Amendment 39-11754 (65 FR 34928, June 1, 2000; corrected August 1, 2000 (65 FR 46862)) is too long because excessive chafing of the sleeving continues to occur much \n\n((Page 24544)) \n\nearlier than expected between scheduled inspections.

Discussion \n\n\n\tWe issued a second supplemental notice of proposed rulemaking (SNPRM) to amend 14 CFR part 39 to supersede AD 2000-11-06, Amendment 39-11754 (65 FR 34928, June 1, 2000; corrected August 1, 2000 (65 FR 46862)). AD 2000-11-06 applied to certain The Boeing Company Model 767 airplanes. The second SNPRM published in the Federal Register on March 8, 2013 (78 FR 14934). We preceded the second SNPRM with a first SNPRM that published in the Federal Register on July 2, 2012 (77 FR 39188). We preceded the first SNPRM with a notice of proposed rulemaking (NPRM) that published in the Federal Register on December 14, 2010 (75 FR 77790). The NPRM was prompted by fleet information indicating that the repetitive inspection interval in AD 2000-11-06 is too long, because excessive chafing of the sleeving continues to occur much earlier than expected between scheduled inspections. The NPRM proposed to continue to require repetitive inspections to detect discrepancies of the wiring and surrounding Teflon sleeves of the fuel tank boost pumps and override/jettison pumps; replacement of the sleeves with new sleeves, for certain airplanes; and repair or replacement of the wiring and sleeves with new parts, as necessary. The NPRM also proposed to reduce the initial compliance time and repetitive inspection interval in AD 2000-11-06. The first SNPRM proposed to mandate a terminating action for the repetitive inspections, to eliminate wire damage. In addition, the first SNPRM proposed to remove certain airplanes from the applicability of AD 2000-11-06. The second SNPRM proposed to require revising the maintenance program to incorporate changes to the airworthiness limitations section. We are issuing this AD to detect and correct chafing of the fuel pump wire insulation and consequent exposure of the electrical conductor, which could result in electrical arcing between the wires and conduit and consequent fire or explosion of the fuel tank. \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 second SNPRM (78 FR 14934, March 8, 2013) and the FAA's response to each comment. Boeing concurred with the content of the second SNPRM. \n\nRequest To Allow Using Maintenance Manual Procedure for Repetitive Inspections \n\n\n\tUnited Airlines (UAL) asked that paragraphs (g), (i)(2)(i)(C), (i)(2)(ii), and (k) of the second SNPRM (78 FR 14934, March 8, 2013) be changed to allow the use of Boeing 767 Airplane Maintenance Manual (AMM) 28-22-15/601 when accomplishing the repetitive inspections required by those paragraphs. UAL stated that Boeing has incorporated the intent of Boeing Service Bulletin 767-28A0053, Revision 3, dated November 11, 2011, into Boeing 767 AMM 28-22-15/601. (Boeing Service Bulletin 767-28A0053, Revision 3, dated November 11, 2011, was cited as an appropriate source of service information in the second SNPRM.) \n\tWe do not agreeto change paragraphs (g), (i)(2)(i)(C), (i)(2)(ii), and (k) of this final rule to allow using Boeing 767 AMM 28-22-15/601 for accomplishing the required repetitive inspections. The procedures specified in that section of the AMM are not FAA-approved. In addition, it is possible that not all operators have a current version of the AMM in their maintenance programs; therefore, it is not possible for us to know which version of the AMM would be used for doing the inspections. Limiting the requirements to a specific AMM procedure and revision level would require an operator to get an approval of an alternative method of compliance (AMOC) for subsequent AMM revisions. Therefore, we have not changed this final rule in this regard. \n\nRequest To Clarify Certain Errors in the Service Information \n\n\n\tUAL asked that the second SNPRM (78 FR 14934, March 8, 2013) refer to the correct figure callouts (which are identified incorrectly in Boeing Alert Service Bulletin 767-28A0104, Revision 1, dated March 2, 2012). UAL stated that paragraph (l) of the second SNPRM specifies using Boeing Alert Service Bulletin 767-28A0104, Revision 1, dated March 2, 2012, to perform terminating action for the repetitive inspections required by paragraphs (g) and (k) of the second SNPRM. UAL also noted that it made the same request in its comments on the first SNPRM (77 FR 39188, July 2, 1012). UAL added that these errors were confirmed by Boeing, but no revised service information has been issued to address these errors. \n\tWe agree with the commenter that the figure callouts are identified incorrectly in Boeing Alert Service Bulletin 767-28A0104, Revision 1, dated March 2, 2012; however, as we specified in a similar response in the first SNPRM (77 FR 39188, July 2, 2012), Boeing has not yet issued revised service information to correct the errors. These errors are minor and do not affect accomplishing the actions specified in the service information. When revised service information is issued,operators may request approval of an AMOC in accordance with the procedures specified in paragraph (p) of this AD. We have not changed this final rule in this regard. \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 as proposed except for minor editorial changes. We have determined that these minor changes: \n\tAre consistent with the intent that was proposed in the second SNPRM (78 FR 14934, March 8, 2013) for correcting the unsafe condition; and \n\tDo not add any additional burden upon the public than was already proposed in the second SNPRM (78 FR 14934, March 8, 2013). \n\nCosts of Compliance \n\n\n\tWe estimate that this AD affects 414 airplanes of U.S. registry. \n\tWe estimate the following costs to comply with this AD: \n\n((Page 24543)) \n\n\n\n\n\n\n\tEstimated Costs ---------------------------------------------------------------------------------------------------------------- \n\tCost on U.S. \n\tAction Labor cost Parts cost Cost per product operators ---------------------------------------------------------------------------------------------------------------- Actions for airplanes with 7 work-hours x $85 None............. $595 per Up to $246,330 per \n\tjettison pumps (retained from per hour = $595 inspection cycle. inspection cycle. \n\tAD 2000-11-06, Amendment 39- per inspection \n\t11754 (65 FR 34928, June 1, cycle. \n\t2000; corrected August 1, 2000 \n\t(65 FR 46862)). Actions for airplanes without 5 work-hours x $85 None............. $425 per Up to $175,950 per \n\tjettison pumps (retained from per hour = $425 inspection cycle. inspection cycle. \n\tAD 2000-11-06, Amendment 39- per inspection \n\t11754 (65 FR 34928, June 1, cycle. \n\t2000; corrected August 1, 2000 \n\t(65 FR 46862)). Newreplacement of wire bundles. 42 work-hours x $85 $6,061........... $9,631............ $3,987,234. \n\tper hour = $3,570. New revision to maintenance 1 work-hour x $85 None............. $85............... $35,190. \n\tprogram. per hour = $85. ---------------------------------------------------------------------------------------------------------------- \n\n\n\tWe estimate the following costs to do any necessary repairs that would be required based on the results of the inspections. We have no way of determining the number of aircraft that might need these repairs: \n\n\n\tOn-Condition Costs ---------------------------------------------------------------------------------------------------------------- \n\tCost per \n\tAction Labor cost Parts cost product ---------------------------------------------------------------------------------------------------------------- Replacement of wire bundle sleeves........... 1 work-hour x $85 per hour = $85..... $1,452 $1,537 ---------------------------------------------------------------------------------------------------------------- \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\tWe have determined that this 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, Incorporation by reference, Safety.
