SUBJECT: WINGS - Leading Edge and Leading Edge Devices - Number 5 and Number 8 Slat

Track Housing Drain Tube Replacement

CONCURRENT REQUIREMENTS

None.

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, as given 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.

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, the change described in Boeing service bulletin 767-57A0094,

which is equivalent to the change given in this service bulletin, was completed on a 767-200ER airplane after

the initial release of service bulletin 767-57A0094. The change completed on the 767-200ER airplane is equivalent

to the change given in the release of Revision 1 of this service bulletin.

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, as given 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.

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, the change described in Boeing service bulletin

767-57A0094, which is equivalent to the change given in this service bulletin, was completed on a

767-200ER airplane after the initial release of service bulletin 767-57A0094. The change completed

on the 767-200ER airplane is equivalent to the change given in Revision 1 of this service bulletin.

Revision 1 of this service bulletin was sent to change 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. The

validation 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 to 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 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.

— Appendix A, Roller Swaging - Wiggins Type Ferrules, is changed to: switch the heading from Roller

Swaging - Wiggins Type Ferrules to Drain Tube 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.

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. A cross reference table is added to the special tooling section to show

the equivalent part numbers for operators who want to order special tools from the Boeing Parts Page.

This revision also adds a female 3/8 inch square drive socket as an alternative to the wrench. The

references to Federal Aviation Administration (FAA) Airworthiness Directive FAA AD 2001-14-19 are

removed from the SB. In addition to these changes, the term "as given in/as shown in" is changed to

"Refer to, as an accepted procedure" to comply with the latest SB standards on non-FAA approved

(or the DH6305-1swage block holder) may be installed in a sturdy bench vise,

instead of in the ST877W-F Frame.

(b) Either a ST877W-DF-D-08-1-2 die block (no link installed) or a DB6305H8 swage

block may be used in place of the ST877W-DF-D-08-1-1 die block.

(c) A DH6305-1 swage block holder may be used in place of the ST877W-DH-1 die

block holder.

(d) Either a B9108-35 tube expander or a B8308-35 tube expander may be used in

place of the ST877W-E-8-035 tube expander.

(e) This tool is only compatible with the ST877W-E-8-035 and the B9108-35 tube

expander. A female 3/8 inch square drive socket can be used for the B8308-35

tube expander.

1. Make sure the AS1716D08 ferrule internal swage grooves are free of debris and/or lubricant.

2. Make sure the outside surface of the 015T1772-2 drain tube is free of scratches and/or gouges in the

swaging areas. Scratches and/or gouges on the drain tube outside surface swaging areas are not acceptable.

If the drain tube outside surface has a scratch and/or gouge in the swaging area that is deeper than 0.001

inch after polishing, the part must be replaced.

3. Make sure the outside surface of the 015T1772-2 drain tube is free of debris and/or lubricant in the swaging

areas.

4. Attach the ST877W-F frame to a sturdy workbench, if the ST877W-DH-1 die block holder will be installed

in the frame. Refer to Item 5 below.

5. Install the ST877W-DH-1 die block holder on the ST877W-F frame. Two 0.5000-13 x (length required) steel

fasteners (operator supplied) are required to secure the die block holder to the frame. Optional to secure

the die block holder in a sturdy bench vise, instead of on the ST877W-F frame. The 0.5000-13 x (length

required) steel fasteners are not required if the die block holder is secured in a bench vise, instead of the

frame.

6. Clean the ST877W-DF-D-08-1-1 die block halves using Denatured Alcohol and a clean cloth, to ensure the

die block halves ferrule cavities are free of debris and/or lubricant.

7. Insert the AS1716D08 ferrule into the ST877W-DF-D-08-1-1 die block half cavity and close the die block

halves.

8. Install the ST877W-DF-D-08-1-1 die block halves (and AS1716D08 ferrule) into the ST877W-DH-1 die

block holder. The flanged end of the AS1716D08 ferrule must be located adjacent to the die block stop in

the die block holder. Align the die block split lines approximately perpendicular to the die block holder split

line.

9. Torque the ST877W-DH-1 die block holder clamping fastener to 100 foot-pounds. Make sure the

ST877W-DF-D-08-1-1 die block halves are fully against the die block holder stop, prior to torque application.

10. Clean the rollers and to the tapered mandrel of the ST877W-E-8-035 tube expander, using Denatured

Alcohol solvent and a clean cloth.

11. Apply SAE No. 10 automotive engine oil lubricant to the rollers and to the tapered end of the ST877W-E-8-035

tube expander. Optional to use Masterdraw B1767C lubricant.

NOTE: Any SAE "10W-xx" (10W-20, 10W-30, 10W-40, etc) automotive engine oil is an acceptable substitute

for SAE No.10 automotive engine oil.

12. Insert the 015T1772-2 drain tube into the AS1716D08 ferrule until it contacts the ferrule tube stop. Hold the

drain tube squarely against the ferrule tube stop until the swage process is completed.

13. Insert the ST877W-E-8-035 tube expander into ST877W-DF-D-08-1-1 die block, opposite the 015T1772-2

drain tube.

14. Push the exposed end of the mandrel towards the ST877W-E-8-035 tube expander body and rotate the

mandrel by hand clockwise, to start the tube expander self-feeding action.

15. Install the ST2580-77A-5 wrench or a female 3/8 inch square drive socket (as applicable), on the end of

the tube expander mandrel.

16. Torque the ST2580-77A-5 wrench (or female 3/8 inch square drive socket) to 16 - 20 inch-pounds. The

mandrel end will advance into the tube expander body as it rotates. Ten or more complete turns of the

wrench may be necessary to reach the required torque.

17. Rotate the mandrel counterclockwise to loosen and remove the ST877W-E-8-035 tube expander.

18. Loosen the ST877W-DH-1 die block holder clamping fastener to remove the ST877W-DF-D-08-1-1 die

block and swaged drain tube/ferrule.

19. Remove the swaged drain tube/ferrule from the ST877W-DF-D-08-1-1 die block halves.
