SUBJECT: WINGS - Leading Edge And Leading Edge Devices - Leading Edge Fluid Drainage

BOEING RECOMMENDS THAT EACH OPERATOR EXAMINE THIS SERVICE BULLETIN IMMEDIATELY.

CONCURRENT REQUIREMENTS

None.

BACKGROUND

This service bulletin gives instructions to modify the fluid drain path in the wing leading edge area, forward of

the wing front spar. If this service bulletin is not incorporated, flammable fluids accumulating in the wing leading

edge may drain inboard and onto the engine exhaust nozzle, which could result in a fire.

Boeing has received a report of leaking fuel from the wing leading edge area at the inboard end of the number

5 leading edge slat of a 737 airplane. The leak was discovered during a post flight inspection with a fuel quantity

of over 2500 lbs. Subsequent investigation found that the leak occurred in an area of the front spar that does

not have a proper drain path. This led to the fuel draining onto the engine exhaust nozzle. The leak appears to

have been caused by a loose retaining nut of the slat track down stop and is the subject of Boeing Service Letter

737-SL-57-084.

Accomplishment of this service bulletin will make sure that there is a drain path to safely direct all fluid leakages

from the wing leading edge away from the engine exhaust area.

Boeing Service Related Problem (SRP) 747-SRP-57-0214 is related to this service bulletin.

As a part of a service bulletin validation program, this change was completed on airplane RT556 by Service

Bulletin 747-57-2332 Original Issue before the release of Revision 1 of this service bulletin. The change completed

on airplane RT556 by Service Bulletin 747-57-2332 Original Issue is equivalent to the release of Revision 1 of

this service bulletin. Airplane RT556 has the configuration of a Group 7 airplane.

ACTION (PRR 85901-96RS)

Get access to the leading edge of the wing by extending the variable camber flaps. Install the applicable fuel

dam assemblies, seal assemblies and drain assemblies. Repair the leading edge lower skin panel. Close access.

2. Spares Affected

None.

B. Concurrent Requirements

None.

C. Reason

This service bulletin gives instructions to modify the fluid drain path in the wing leading edge area,

forward of the wing front spar. If this service bulletin is not incorporated, flammable fluids accumulating

in the wing leading edge may drain inboard and onto the engine exhaust nozzle, which could result in

a fire.

Revision 1: July 25, 2011 747-57-2332

BOEING SERVICE BULLETIN 747-57-2332
Boeing has received a report of leaking fuel from the wing leading edge area at the inboard end of the

number 5 leading edge slat of a 737 airplane. The leak was discovered during a post flight inspection

with a fuel quantity of over 2500 lbs. Subsequent investigation found that the leak occurred in an area

of the front spar that does not have a proper drain path. This led to the fuel draining onto the engine

exhaust nozzle. The leak appears to have been caused by a loose retaining nut of the slat track down

stop and is the subject of Boeing Service Letter 737-SL-57-084.

Accomplishment of this service bulletin will make sure that there is a drain path to safely direct all fluid

leakages from the wing leading edge away from the engine exhaust area.

Boeing Service Related Problem (SRP) 747-SRP-57-0214 is related to this service bulletin.

Revision 1 is sent to include supplemental and replacement kits and to add optional materials.

As a part of a service bulletin validation program, this change was completed on airplane RT556 by

Service Bulletin 747-57-2332 Original Issue before the release of Revision 1 of this service bulletin.

The change completed on airplane RT556 by Service Bulletin 747-57-2332 Original Issue is equivalent

to the release of Revision 1 of this service bulletin. Airplane RT556 has the configuration of a Group 7

airplane.

D. Description

Get access to the leading edge of the wing by extending the variable camber flaps. Install the applicable

fuel dam assemblies, seal assemblies and drain assemblies. Repair the leading edge lower skin panel.

Close access.

Revision 1:
