SUBJECT: WINGS - Center Wing - Outer Wing - Change to Fasteners in Fuel Tank Walls and
Change to Wire Bundle Clamps
This Revision includes all pages of the service bulletin.
COMPLIANCE INFORMATION RELATED TO THIS REVISION
More work is necessary on airplanes changed as shown in the original issue of this service bulletin. Refer to
Work Package 10, 11 and 12 for work instructions.
REASON FOR REVISION
This revision is sent to correct the specified location of fasteners that must be sealed on the rear spar in the
auxiliary fuel tank, correct the specified location of fasteners that must be sealed at rib 28 on the front spar, add
Work Packages for airplanes that accomplished the original issue of this service bulletin, add references to more
access doors that are necessary to get access to the fuel tanks and to specify permitted alternative fuel tank
sealants.
New Work Packages are necessary because the original issue of this service bulletin specified the incorrect
locations for certain fasteners on the rear spar of the auxiliary fuel tank and the front spar of the main wing. The
new Work Packages do a general visual inspection of certain fasteners in the fuel tanks for sealant and seals
the fasteners if they are not sealed already. If the correct fasteners are not sealed, there is a risk that arcing
from a short can enter the fuel tank and be an ignition source.
These sections were changed:
1. In Planning Information, Paragraph 1.G, updated the manpower estimates.
2. In Material Information - Parts Necessary for Each Airplane, Paragraph 2.C., added permitted alternative
fuel tank sealants specified in 767 AMM 28-11-00.
3. In Accomplishment Instructions, Paragraph 3.B, added access doors 541FB, 541JB, 542BB, 542CB, and
532AZ to Work Package 5 to gain access to the fuel tank.
4. In Accomplishment Instructions, Paragraph 3.B, added access doors 641FB, 641JB, 642BB, 642CB, and
632AZ to Work Package 6 to gain access to the fuel tank.
5. In Accomplishment Instructions, Paragraph 3.B, added access doors 134BZ, 134CZ, 134DZ, 134EZ, 134FZ,
and 134GZ are added to Work Package 7 to gain access to the fuel tank.
6. In Accomplishment Instructions, Paragraph 3.B, added Work Package 10, 11, and 12 to show more work
for airplanes changed as shown in the original issue of this service bulletin.

10. In Figure 22, revised the location of the fasteners that must be sealed from rib 27 to rib 28.
11. In Figure 24, revised the location of the fasteners that must be sealed from rib 27 to rib 28.
12. In Figure 25, revised the orientation of the structure to show the right side view.
13. In Figure 28, revised the illustration to show the correct locator and BBL references that show the location
of the fasteners that must be sealed on the rear spar in the auxiliary fuel tank.
14. In Figure 29, revised the illustration to show the correct locator and BBL references that show the location
of the fasteners that must be sealed on the rear spar in the auxiliary fuel tank.

Revision 1: November 27, 2007
ATA System: 5710 5720 2811
SUBJECT: WINGS - Center Wing - Outer Wing - Change to Fasteners in Fuel Tank Walls and
Change to Wire Bundle Clamps
CONCURRENT REQUIREMENTS
None.
BACKGROUND
Accomplishment of the modifications within this service bulletin will help prevent possible ignition sources in the
auxiliary fuel tank, main fuel tanks, and surge tanks caused by a wiring short. An ignition source in a fuel tank
could result in a fire or an explosion.
A safety assessment by Boeing identified a certain type of fastener that penetrates the fuel tank wall and has
an insufficient electrical bond to the fuel tank structure. These fasteners can be a path for electrical energy to
enter the fuel tank if a wiring short occurs in a wire bundle installed along the fuel tank boundary structure. The
electrical energy from the wiring short can go through these fasteners because they have an insufficient bond
to the fuel tank structure. This energy can be sufficient to cause arcing at the ends of these fasteners in the fuel
tank. If arcing occurs it can be an ignition source in a fuel tank.
This Service Bulletin makes these changes where a high energy short can occur and certain fasteners are
installed: Installs a polytetraflouroethylene (TFE) sleeve on the wire bundles where the wire bundle clamp is
installed to give more protection from chafing, replaces the wire bundle clamps with a different design that has
better protection on its metal edges, and seals the ends of the fasteners in the fuel tanks to contain the electrical
energy from a wiring short. These changes make sure that the risk of an ignition source in the fuel tank from a
short is kept to a minimum.
This service bulletin is the result of the safety assessments conducted by Boeing under SFAR 88, "Fuel Tank
System Fault Tolerance Evaluation Requirements".
ACTION (PRR B13421-11)

2. Spares Affected
None.
B. Concurrent Requirements
None.
C. Reason
Accomplishment of the modifications within this service bulletin will help prevent possible ignition
sources in the auxiliary fuel tank, main fuel tanks, and surge tanks caused by a wiring short. An ignition
source in a fuel tank could result in a fire or an explosion.
A safety assessment by Boeing identified a certain type of fastener that penetrates the fuel tank wall
and has an insufficient electrical bond to the fuel tank structure. These fasteners can be a path for
electrical energy to enter the fuel tank if a wiring short occurs in a wire bundle installed along the fuel
tank boundary structure. The electrical energy from the wiring short can go through these fasteners
because they have an insufficient bond to the fuel tank structure.This energy can be sufficient to cause
arcing at the ends of these fasteners in the fuel tank. If arcing occurs it can be an ignition source in a
fuel tank.
This Service Bulletin makes these changes where a high energy wiring short can occur and certain
fasteners are installed: Installs a polytetraflouroethylene (TFE) sleeve on the wire bundles where the
wire bundle clamp is installed to give more protection from chafing, replaces the wire bundle clamps
with a different design that has better protection on its metal edges, and seals the ends of the fasteners
in the fuel tanks to contain the electrical energy from a wiring short. These changes make sure that
the risk of an ignition source in the fuel tank from a short is kept to a minimum.
This service bulletin is the result of the safety assessments conducted by Boeing under SFAR 88, "Fuel
Tank System Fault Tolerance Evaluation Requirements".

### Page 18

Revision 1 is sent to correct the specified location of fasteners that must be sealed on the rear spar in
the auxiliary fuel tank, correct the specified location of fasteners that must be sealed at rib 28 on the
front spar, add Work Packages for airplanes that accomplished the original issue of this service bulletin,
add references to more access doors that are necessary to get access to the fuel tanks and to specify
permitted alternative fuel tank sealants.
New Work Packages are necessary because the original issue of this service bulletin specified the
incorrect locations for certain fasteners on the rear spar of the auxiliary fuel tank and the front spar of
the main wing. The new Work Packages do a general visual inspection of certain fasteners in the fuel
tanks for sealant and seals the fasteners if they are not sealed already. If the correct fasteners are not
sealed, there is a risk that arcing from a short can enter the fuel tank and be an ignition source.
These sections were changed in Revision 1:
1. In Planning Information, Paragraph 1.G, updated the manpower estimates.
2. In Material Information - Parts Necessary for Each Airplane, Paragraph 2.C., added permitted
alternative fuel tank sealants specified in 767 AMM 28-11-00.
3. In Accomplishment Instructions, Paragraph 3.B, added access doors 541FB, 541JB, 542BB,
542CB, and 532AZ to Work Package 5 to gain access to the fuel tank.
4. In Accomplishment Instructions, Paragraph 3.B, added access doors 641FB, 641JB, 642BB,
642CB, and 632AZ to Work Package 6 to gain access to the fuel tank.
5. In Accomplishment Instructions, Paragraph 3.B, added access doors 134BZ, 134CZ, 134DZ,
134EZ, 134FZ, and 134GZ are added to Work Package 7 to gain access to the fuel tank.
6. In Accomplishment Instructions, Paragraph 3.B, added Work Package 10, 11, and 12 to show
more work for airplanes changed as shown in the original issue of this service bulletin.
7. In Figure 2 and 3, revised the procedure to install the sleeve to it more clear.
8. In Figure 17, 18, 20, 22, 24, 26, and 27, added a reference to the AMM for permitted alternative
fuel tank sealants.
9. In Figure 18, revised the location of the fasteners that must be sealed from rib 27 to rib 28.
10. In Figure 22, revised the location of the fasteners that must be sealed from rib 27 to rib 28.
11. In Figure 24, revised the location of the fasteners that must be sealed from rib 27 to rib 28.
12. In Figure 25, revised the orientation of the structure to show the right side view.
13. In Figure 28, revised the illustration to show the correct locator and BBL references that show the
location of the fasteners that must be sealed on the rear spar in the auxiliary fuel tank.
14. In Figure 29, revised the illustration to show the correct locator and BBL references that show the
location of the fasteners that must be sealed on the rear spar in the auxiliary fuel tank.
D. Description
This service bulletin is divided into work packages that are related to the different areas of the airplane.
