CONCURRENT REQUIREMENTS Group 1-2: You cannot make the changes in accordance with this service bulletin unless the changes in accordance with Part III - Terminating Action of either Boeing service bulletin 767-57A0060 Revision 1, dated December 31, 1998, or 767-57A0060 Revision 2, dated January 31, 2002, are made. Part III - Terminating Action of either Boeing service bulletin 767-57A0060 Revision 1 or 767-57A0060 Revision 2, provides instructions to install new number 5 and number 8 slat track housing drain tube assemblies, to prevent possible fuel leakage near an engine or exhaust nozzle, when the airplane is on the ground.

Group 2: You cannot make the changes in accordance with this service bulletin unless the changes in accordance with Part IV - Additional Work of either Boeing service bulletin 767-57A0060 Revision 1, dated December 31, 1998, or 767-57A0060 Revision 2, dated January 31, 2002, are made. Part IV - Additional Work installs an additional electrostatic bond path for the number 5 and 8 inboard slat track drain tube assemblies.

Group 3: You cannot make the changes in accordance with this service bulletin unless the changes in accordance with Boeing service bulletin 767-57-0068 Revision 1, dated May 09, 2002, are made. Service bulletin 767-57-0068 Revision 1, dated May 09, 2002, gives instructions to make a better electrostatic bond for the number 5 and number 8 slat track housing drain tube assemblies.

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 rerouted 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.

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.
