SUBJECT: WINGS - Outer Wing - Change to Fasteners in Fuel Tank Walls - Application of Sealant
This revision includes all pages of the service bulletin.
COMPLIANCE INFORMATION RELATED TO THIS REVISION
Federal Aviation Administration (FAA) Notice of Proposed Rule Making 2006-NM-293-AD, is related to this
service bulletin.
No more work is necessary on airplanes changed as shown in the original issue of this service bulletin.
REASON FOR REVISION
This revision is sent to to give instructions to do a General Visual Inspection of the vortex generators on certain
airplanes. Before work is done, the vortex generators on certain airplanes must be inspected to determine if the
vortex generators are installed with fasteners or adhesive alone. An operator reported that the vortex generators
on some 767 airplanes are attached with adhesive alone. If fasteners are not used to install the vortex generators
it is not necessary to apply sealant at these locations. A review of the engineering drawing for the upper wing
inspar panel installation confirms that some airplanes in a certain line number range were delivered with vortex
generators that are attached by adhesive alone.
These sections were changed:
1. Summary, Action, added actions for a General Visual inspection to determine if the vortex generators are
attached with fasteners or adhesive alone.
2. Summary, Compliance, added a reference to Federal Aviation Administration (FAA) Notice of Proposed
Rule Making 2006-NM-293-AD.
3. Summary, Manpower, added manpower for Group 3 airplanes.
4. Paragraph 1.A, Effectivity; added a new Group 3 and moved airplanes VA516-VA519, VB122-VB123,
VE041, VE067-VE068, VE102-VE103, VE116-VE117, VK001-VK003, and VK031 from Group 1 to Group
3.
5. Paragraph 1.D., Description, added actions for a General Visual Inspection to determine if the vortex
generators are attached with fasteners or adhesive alone.
6. Paragraph 1.D., added Maintenance Zones.
7. Paragraph 1.E., Compliance, added a reference to FAA Notice of Proposed Rule Making 2006-NM-293-AD.

generators are attached with fasteners or adhesive alone.
11. Paragraph 3., Accomplishment Instructions, added new Figures 6 and 7 to do a General Visual Inspection
of the vortex generators on the wings.
The data given in Information Notice 767-57A0100 IN 01 is included in this revision.

Revision 1: June 19, 2008
ATA System: 5720 2811
SUBJECT: WINGS - Outer Wing - Change to Fasteners in Fuel Tank Walls - Application of Sealant
CONCURRENT REQUIREMENTS
None.
BACKGROUND
Accomplishment of the modifications within this service bulletin will help prevent possible ignition sources in the
main fuel tanks, and the surge tanks caused by a lightning strike on certain wing surfaces. An ignition source
in a fuel tank could result in a fire or an explosion.
A review by Boeing identified a certain fastener type in the fuel tank walls that have an insufficient bond to the
structure. If energy from lightning strike goes through these fasteners, arcing can occur at the ends of the
fasteners in the fuel tank. The ends of the fasteners in the fuel tank do not have sufficient electrical insulation
to contain the energy from the arcs.
This Service Bulletin gives the instructions to seal the end of certain fasteners in the fuel tank walls. These
changes make sure that the risk of an ignition source in the fuel tank from a lightning strike on the wing 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 B13421-10)
Group 1:
Prepare the main fuel tanks for entry. Get access to the left main tank. Seal the ends of the fasteners on the
brackets that hold the vortex generators. Get access to the right main tank. Seal the ends of the fasteners on
the brackets that hold the vortex generators. Close access to the main fuel tanks.
Group 2:
Prepare the main fuel tanks for entry. Get access to the left main tank. Seal the ends of the fasteners on the
brackets that hold the vortex generators. Seal the ends of fasteners on certain stiffeners on the rear spar. Get
access to the right main tank. Seal the ends of the fasteners on the brackets that hold the vortex generators.
Seal the ends of fasteners on certain stiffeners on the rear spar. Close access to the main fuel tanks.

Group 3:
Get access to the outer surface of the upper wing panel on the left wing. Do a General Visual Inspection of the
specified vortex generators on the upper wing panel of the left wing. Get access to the outer surface of the upper
wing panel on the right wing. Do a General Visual Inspection of the specified vortex generators on the upper
wing panel on the right wing. If the vortex generators are attached with adhesive alone, no more work is necessary.
If the vortex generators are attached with fasteners, do the following steps: Prepare the main fuel tanks for entry.
Get access to the left main tank. Seal the ends of the fasteners on the brackets that hold the vortex generators.
Get access to the right main tank. Seal the ends of the fasteners on the brackets that hold the vortex generators.
Close access to the main fuel tanks.
Service Bulletin 767-57A0102 has similar access requirements as this bulletin and can be incorporated at the
same time or separately. Service Bulletin 767-57A0102 is separate from this bulletin because it makes
improvements to existing design and does not have warranty remedies.
EFFECTIVITY
767 Airplanes. See Service Bulletin Paragraph 1.A.1 for effectivity.
COMPLIANCE
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.
Boeing recommends that this service bulletin be incorporated within 5 years after the date on this service bulletin.
Federal Aviation Administration (FAA) Notice of Proposed Rule Making 2006-NM-293-AD, is related to this
service bulletin.
INDUSTRY SUPPORT INFORMATION

This estimate is for direct labor only, done by an experienced crew. Adjust the estimate with operator
task-hour data if necessary. The estimate does not include lost time. These are some examples of lost
time:
— Time to adjust to the workplace
— Time to schedule the work
— Time to examine the work
— Time to cure the materials
— Time to make the parts
— Time to find the tools.

A. GENERAL INFORMATION
CAUTION: KEEP THE WORK AREA, WIRES AND ELECTRICAL BUNDLES CLEAN OF METAL
PARTICLES OR CONTAMINATION WHEN YOU USE TOOLS. UNWANTED MATERIAL,
METAL PARTICLES OR CONTAMINATION CAUGHT IN WIRE BUNDLES CAN CAUSE
DAMAGE TO THE BUNDLES. DAMAGED WIRE BUNDLES CAN CAUSE SPARKS OR
OTHER ELECTRICAL DAMAGE.
NOTE: 1. Manual titles are referred to by acronyms. Refer to Paragraph 1.J., References, for
definition of the acronyms.
2. Obey all of the warnings and cautions given in the specified manual sections.
3. A General Visual Inspection is defined as: A visual examination of an interior or
exterior area, installation or assembly to detect obvious damage, failure or irregularity.
This level of inspection is made from within touching distance unless otherwise
specified. A mirror may be necessary to ensure visual access to all surfaces in the
inspection area. This level of inspection is made under normal available lighting
conditions such as daylight, hangar lighting, flashlight or drop-light and may require
removal or opening of access panels or doors. Stands, ladders or platforms may be
required to gain proximity to the area being checked.
4. These work instructions refer to procedures included in other Boeing documents.
When the words "refer to" are used and the operator has an accepted alternative
procedure, the accepted alternative procedure can be used. When the words "as
given in" are included in the instruction, the procedure in the Boeing document must
be used.
