Group 4: These airplanes are not affected by either Boeing service bulletin 767-57A0060 or 767-57-0068. Refer to service bulletin Paragraph 1.B., Concurrent Requirements, for more information. BACKGROUND Accomplishment of this service bulletin prevents cracks in the number 5 and number 8 slat track housing drain tubes. Cracks in these drain tubes could let fuel drain from the main fuel tanks into the dry bay area of the wings. Fuel from the dry bay areas could subsequently drain on to hot Main Landing Gear (MLG) brakes and possibly result in a fire. One operator told Boeing of a fuel leak on to the MLG as a result of a cracked drain tube at the number 8 slat track housing, no fire was reported. The crack was in a drain tube on a 767 airplane that had incorporated a re- routed drain tube with a flexible part, in accordance with Boeing service bulletin 767-57A0060. An investigation by Boeing found that the drain tube with a flexible part had cracked as a result of a high intensity engine vibration, which was more than the design of the tube permitted. ### Page 8 Original Issue: June 02, 2005 Revision 2: December 17, 2009 767-57A0094 BOEING PROPRIETARY - Copyright © Unpublished Work - See page 1 for details. 8 of 141 Boeing was told of a second occurrence of a cracked drain tube at the number 8 slat track housing. The crack in the flexible part of the drain tube was found after an airplane had a high intensity engine vibration. During flight, an airplane had vibration from the number 2 engine (Pratt & Whitney PW4000) as a result of a second stage turbine blade failure. The engine was subsequently shut-down and the airplane was diverted. After the airplane had landed fuel leakage was seen from the pylon area by maintenance personnel. This problem affects airplane line numbers 1 thru 921. Airplanes after line number 921 have a production design change which installs the new drain tube without a flexible part. This service bulletin gives instructions to replace a drain tube assembly which has a flexible part with a new aluminum drain tube without a flexible part, at the number 5 and number 8 slat track housing. Boeing tests have shown that the new aluminum drain tubes are stronger and more resistant to damage during high intensity engine vibrations. Boeing Service Related Problem (SRP) 767-SRP-57-0160 is related to this service bulletin. As a part of a service bulletin validation program, this change was completed on airplane VR084 after the initial release of this service bulletin. The change completed on airplane VR084 is equivalent to the change given in Revision 1 of this service bulletin. Airplane VR084 has the configuration of a Group 4 airplane. ACTION (PRR B12901-53S) Defuel the left and right wing main tanks. Open the applicable left and right wing main tank access panels to get access to the number 5 and number 8 slat track housing drain tubes. Remove the existing drain tube assemblies that have a flexible part. Prepare and install new aluminum drain tubes without a flexible part at the two locations. Close the left and right wing main tank fuel bay access panels. Refuel the left and right wing main tanks. Inspect the left and right wing main tank dry bay to make sure there is no fuel leakage from the new drain tube installations. Close the left and right wing main tank dry bay access panels. EFFECTIVITY 767-200/300/300F Airplanes. Refer to service bulletin Paragraph 1.A.1 for effectivity. COMPLIANCE Boeing recommends that this service bulletin is done no later than 24 months after the Revision 1 date of this service bulletin. Federal Aviation Administration (FAA) Airworthiness Directive AD 2001-14-19 is related to this service bulletin. The Federal Aviation Administration (FAA) will possibly release an Airworthiness Directive related to this service bulletin. The Airworthiness Directive will make the compliance tasks and times given in this service bulletin mandatory. INDUSTRY SUPPORT INFORMATION Boeing warranty remedies are not available for the configuration changes given in this service bulletin. ### Page 9 Original Issue: June 02, 2005 Revision 2: December 17, 2009 767-57A0094 BOEING PROPRIETARY - Copyright © Unpublished Work - See page 1 for details. 9 of 141 BOEING SERVICE BULLETIN 767-57A0094 MANPOWER MATERIAL INFORMATION Boeing Supplied Kits.

Group 3: If Boeing service bulletin 767-57-0068 Revision 1 was previously accomplished on the airplane, do the work instructions in accordance with this service bulletin. Group 4: These airplanes are not affected by either Boeing service bulletin 767-57A0060 or 767-57-0068. C. Reason Accomplishment of this service bulletin prevents cracks in the number 5 and number 8 slat track housing drain tubes. Cracks in these drain tubes could let fuel drain from the main fuel tanks into the dry bay area of the wings. Fuel from the dry bay areas could subsequently drain on to hot Main Landing Gear (MLG) brakes and possibly result in a fire. One operator told Boeing of a fuel leak on to the MLG as a result of a cracked drain tube at the number 8 slat track housing, no fire was reported. The crack was in a drain tube on a 767 airplane that had incorporated a re-routed drain tube with a flexible part, in accordance with Boeing service bulletin 767-57A0060. An investigation by Boeing found that the drain tube with a flexible part had cracked as a result of a high intensity engine vibration, which was more than the design of the tube permitted. Boeing was told of a second occurrence of a cracked drain tube at the number 8 slat track housing. The crack in the flexible part of the drain tube was found after an airplane had a high intensity engine vibration. During flight, an airplane had vibration from the number 2 engine (Pratt & Whitney PW4000) as a result of a second stage turbine blade failure. The engine was subsequently shut-down and the airplane was diverted. After the airplane had landed fuel leakage was seen from the pylon area by maintenance personnel. This problem affects airplane line numbers 1 thru 921. Airplanes after line number 921 have a production design change which installs the new drain tube without a flexible part. ### Page 27 Original Issue: June 02, 2005 Revision 2: December 17, 2009 767-57A0094 BOEING PROPRIETARY - Copyright © Unpublished Work - See page 1 for details. 27 of 141 BOEING SERVICE BULLETIN 767-57A0094 This service bulletin gives instructions to replace a drain tube assembly which has a flexible part with a new aluminum drain tube without a flexible part, at the number 5 and number 8 slat track housing. Boeing tests have shown that the new aluminum drain tubes are stronger and more resistant to damage during high intensity engine vibrations. Boeing Service Related Problem (SRP) 767-SRP-57-0160 is related to this service bulletin. As a part of a service bulletin validation program, this change was completed on airplane VR084 after the initial release of this service bulletin. The change completed on airplane VR084 is equivalent to the change given in Revision 1 of this service bulletin. Airplane VR084 has the configuration of a Group 4 airplane. Revision 1 was sent to make changes to the sequence of the work instructions and to change the safety wire part number, as a result of the airplane validation. The validation found that the step to close the main wing tank access panels was incorrectly located after the refuel step. It also found that the minimum fuel quantity note was incorrectly located after the dry bay inspection step. Special tools required to roller swage the drain tubes onto the ferrules, are specified in this revision. The changes in Revision 1 of this service bulletin are as follows: — The Summary, Background paragraph and Paragraph 1.C., Reason, are changed to include the airplane validation data. — The Summary, Compliance paragraph and Paragraph 1.E., Compliance, are revised to provide additional information on the concurrent requirements for each group of airplanes, relative to Boeing service bulletins 767-57A0060 and 767-57-0068. — The Summary, Compliance paragraph and Paragraph 1.E., Compliance, are revised to change the recommended compliance time from 24 months after the initial release of this service bulletin, to 24 months after the Revision 1 release of this service bulletin. The compliance time is changed due to the special roller swage tools required to accomplish this service bulletin, and the difficulty operators have experienced with special roller swage tool procurement. — Paragraph 1.G., Manpower, is changed to agree with the resequenced steps to close the main wing tank fuel bay access panels prior to the refuel step, in Paragraph 3.B., Work Instructions. — Paragraph 2.C.2., Parts and Materials Supplied by the Operator, is changed to correct the safety wire part number from NASM20995AB32 to MS20995AB32, and to delete the BACT11SD08 tape. — Paragraph 2.E., Special Tooling - Price and Availability, is changed to include the special roller swage tools data. — Paragraph 2.F., Special Tooling Necessary to do this Service Bulletin, is changed to include the special roller swage tools data. — Paragraph 3.B., Work Instructions, for all airplane groups, are changed to resequence the steps to close the main wing tank fuel bay access panels prior to the refuel step, and to move the minimum fuel quantity note for the fuel leakage inspection to the refuel step. — Figures 9 and 10, are changed to delete the BACT11SD08 tape and the reference to BAC5001. — Figures 11 thru 18, are changed to correct the safety wire part number from NASM20995AB32 to MS0995AB32. — Appendix A, Roller Swaging - Wiggins Type Ferrules, is changed to: switch the heading from Roller Swaging - Wiggins Type Ferrules to Roller Swage Instructions; identify the required special roller swage tools, add illustrations to depict special roller swage tools usage, and delete the groove fill acceptance criteria. ### Page 28 Original Issue: June 02, 2005 Revision 2: December 17, 2009 767-57A0094 BOEING PROPRIETARY - Copyright © Unpublished Work - See page 1 for details. 28 of 141 BOEING SERVICE BULLETIN 767-57A0094 Revision 2 is sent to add the option for operators to make their own drain tubes and add some optional materials to the service bulletin.
