IF AN AIRPLANE HAS BEEN LEASED OR SOLD, SEND THIS SERVICE BULLETIN TO THE NEW OPERATOR. IF APPLICABLE SPARES HAVE BEEN SOLD, SEND THIS SERVICE BULLETIN TO THE NEW OWNER. CONCURRENT REQUIREMENTS Boeing service bulletin 737-28-1196, original issue, dated December 5, 2002, or revision 1, dated March 13, 2003, or revision 2, dated August 21, 2003 or revision 3, dated April 1, 2004, is necessary to be accomplished prior to or concurrent with this service bulletin. Service Bulletin 737-28-1196 describes procedures to change wire connections for the engine fuel shutoff valves and for the outboard landing lights. BACKGROUND This service bulletin gives instructions to isolate the outboard landing lights in wire bundles W802 and W804 or add new wires to the outboard landing lights. Potential hot shorts between the outboard landing light and other wires in the wire bundles can cause flight deck indications with no uncommanded engine shutdown. If this service bulletin is not done a potential hot short of a 115 volt outboard landing light to the fuel shutoff valve could cause the fuel shutoff valve to close and an uncommanded engine shutdown. The accomplishment of this service bulletin will prevent an uncommanded engine shutdown due to a hot short between the outboard landing light and the fuel shutoff valve and prevent flight deck indications in the systems in the W802 and W804 wire bundles. This service bulletin gives interim action to prevent an uncommanded engine shutdown due to a hot short between the outboard landing light and the fuel shutoff valve. Replacement of wire bundles W802 and W804 as given in service bulletin 737-28-1241 will eliminate the potential for shorting of the landing light wires and the fuel shutoff wires causing uncommanded engine shutdowns. ACTION Do PART 1 or PART 2: PART 1 - Isolate the outboard landing lights by opening the circuit breakers, installing collars and ‘do not close’ tags and cap and stow the wires from the circuit breakers for the outboard landing lights. There is no Master Minimum Equipment List relief allowance for this configuration should the inboard landing light fail. ### Page 6 May 22, 2006 737-33A1140 BOEING PROPRIETARY - Copyright © Unpublished Work - See page 1 for details. 6 of 52 BOEING SERVICE BULLETIN 737-33A1140 ALERT ALERT PART 2 - Cap and stow the existing wires and install new wires to the outboard landing lights.

Spares Affected None. B. Concurrent Requirements Boeing service bulletin 737-28-1196, original issue, dated December 5, 2002, or revision 1, dated March 13, 2003, or revision 2, dated August 21, 2003 or revision 3, dated April 1, 2004, is necessary to be accomplished prior to or concurrent with this service bulletin. Service Bulletin 737-28-1196 describes procedures to change wire connections for the engine fuel shutoff valves and for the outboard landing lights. C. Reason This service bulletin gives instructions to isolate the outboard landing lights in wire bundles W802 and W804 or add new wires to the outboard landing lights. Potential hot shorts between the outboard landing light and other wires in the wire bundles can cause flight deck indications with no uncommanded engine shutdown. If this service bulletin is not done a potential hot short of a 115 volt outboard landing light to the fuel shutoff valve could cause the fuel shutoff valve to close and an uncommanded engine shutdown. The accomplishment of this service bulletin will prevent an uncommanded engine shutdown due to a hot short between the outboard landing light and the fuel shutoff valve and prevent flight deck indications in the systems in the W802 and W804 wire bundles. This service bulletin gives interim action to prevent an uncommanded engine shutdown due to a hot short between the outboard landing light and the fuel shutoff valve. Replacement of wire bundles W802 and W804 as given in service bulletin 737-28-1241 will eliminate the potential for shorting of the landing light wires and the fuel shutoff wires causing uncommanded engine shutdowns. D. Description Do one of the following PARTs: PW571–PW576 1 PW591–PW596 1 PW611–PW620 1 PW631–PW634 1 PW661–PW662 1 PW681–PW683 1 PW701–PW702 1 PW711–PW717 1 PW741–PW742 1 PW761 1 PW771 1 Variable Group ### Page 25 May 22, 2006 737-33A1140 BOEING PROPRIETARY - Copyright © Unpublished Work - See page 1 for details. 25 of 52 BOEING SERVICE BULLETIN 737-33A1140 ALERT ALERT PART 1 - Isolate the outboard landing lights by opening the circuit breakers, installing collars and "do not close" tags and cap and stow the wires from the circuit breakers for the outboard landing lights. There is no Master Minimum Equipment List relief allowance for this configuration should the inboard landing light fail. PART 2 - Cap and stow the existing wires and install new wires to the outboard landing lights. E.
