REVISION HISTORY Original Issue: July 19, 2006 Revision 1: December 19, 2007 Revision 2: April 19, 2010 Original Issue: July 19, 2006 Revision 2: April 19, 2010 757-30-0019 BOEING PROPRIETARY - Copyright © Unpublished Work - See page 1 for details. 7 of 58 Commercial Airplanes 757 SPECIAL ATTENTION Service Bulletin Number: 757-30-0019 Summary Original Issue: July 19, 2006 Revision 2: April 19, 2010 ATA System: 3041 5611 SUBJECT: ICE AND RAIN PROTECTION - Flight Compartment Window Anti-Icing - Windshield Inspection and Replacement BOEING RECOMMENDS THAT EACH OPERATOR EXAMINE THIS SERVICE BULLETIN IMMEDIATELY. CONCURRENT REQUIREMENTS None BACKGROUND This service bulletin gives instructions to do an inspection of the electrical connections on the left and the right windshields. Instructions are also given to replace the windshields and make changes to their related wire bundles. A new windshield design is available that uses a different electrical connection. Boeing received nine reports from eight operators of electrical arcs at the terminal blocks of the flight compartment windows. More than one of these reports included data to show that the results of the arcs were open flame incidents. One operator found an indication of damage at a terminal and tightened a loose connection. The terminal had internal damage that could not be seen. Less than six months after the connection was tightened there was a report from the operator of an open flame incident on the same windshield. The electrical connections on the windows are made with lugs that are attached with screws. The windshield is the number 1 window in the flight compartment. All of the windows in the flight compartment are electrically heated. The windshield gets a much larger electrical load. An investigation found that the cause of the electrical arcs is loose terminal connections. A loose connection increases the heat at the terminal which can cause damage to the internal solder joint. Damaged solder joints are the primary cause for the electrical arcs. The primary causes of loose connections are the incorrect torque of the screw or an incorrectly installed screw. The inspection given in this service bulletin is to look for damage or a loose electrical connection on the windshield. If there are indications of electrical arcs or damage to the electrical connection, the windshield is replaced. If there is a loose electrical connection, the correct torque is applied to tighten it. If a connection cannot be tightened to the correct torque, the windshield is replaced. When a windshield with an electrical connection that uses pins and sockets is installed, the related wire bundle on the airplane is changed.

The new connections are made with pins and sockets. The pin and socket connections will prevent the risk of electrical arcs as a result of loose connections. Boeing Service Related Problems (SRP) 757-SRP-30-0031 and 757-SRP-56-0015 are related to this service bulletin. As a part of a service bulletin validation program, this change was completed on airplane NB141 by Service Bulletin 757-30-0019 Validation Copy 1 before the initial release of this service bulletin. The change completed on airplane NB141 by Service Bulletin 757-30-0019 Validation Copy 1 is equivalent to the initial release of this service bulletin. Airplane NB141 has the configuration of a Group 1 airplane. ACTION (PRR 54530-265S) In the flight compartment, do an inspection of the J1, J4 and J5 terminals on the left and the right windshields. Replace windshields that use screws and lugs for the electrical connections with a windshield that uses pins and sockets for the electrical connections. Cut the bulb seal to give clearance for terminals on the new windshield. Change the related wire bundle. EFFECTIVITY All 757-200, -200CB, and -200PF Airplanes except NA001.

Spares Affected Examine your spares supply for the parts or components identified in Paragraph 2.C., Parts Necessary for Each Airplane. If any parts or components are found, refer to Paragraph 2.C. for the recommended use. B. Concurrent Requirements None C. Reason This service bulletin gives instructions to do an inspection of the electrical connections on the left and the right windshields. Instructions are also given to replace the windshields and make changes to their related wire bundles. A new windshield design is available that uses a different electrical connection. Boeing received nine reports from eight operators of electrical arcs at the terminal blocks of the flight compartment windows. More than one of these reports included data to show that the results of the arcs were open flame incidents. One operator found an indication of damage at a terminal and tightened a loose connection. The terminal had internal damage that could not be seen. Less than six months after the connection was tightened there was a report from the operator of an open flame incident on the same windshield. The electrical connections on the windows are made with lugs that are attached with screws. The windshield is the number 1 window in the flight compartment. All of the windows in the flight compartment are electrically heated. The windshield gets a much larger electrical load. An investigation found that the cause of the electrical arcs is loose terminal connections. A loose connection increases the heat at the terminal which can cause damage to the internal solder joint. Damaged solder joints are the primary cause for the electrical arcs. The primary causes of loose connections are the incorrect torque of the screw or an incorrectly installed screw. The inspection given in this service bulletin is to look for damage or a loose electrical connection on the windshield. If there are indications of electrical arcs or damage to the electrical connection, the windshield is replaced. If there is a loose electrical connection, the correct torque is applied to tighten it. If a connection cannot be tightened to the correct torque, the windshield is replaced. When a windshield with an electrical connection that uses pins and sockets is installed, the related wire bundle on the airplane is changed. When the changes given in this bulletin are done, the windshields will have better electrical connections. The new connections are made with pins and sockets. The pin and socket connections will prevent the risk of electrical arcs as a result of loose connections.

Approval This service bulletin was examined by the Federal Aviation Administration (FAA). The changes specified in this service bulletin comply with the applicable regulations and are FAA approved, as well as European Aviation Safety Agency (EASA)/Joint Aviation Authorities (JAA) approved for all EASA/ JAA approved airplanes listed in the service bulletin effectivity. This service bulletin and its approval were based on the airplane in its original Boeing delivery configuration or as modified by other approved Boeing changes. If an airplane has a non-Boeing modification or repair that affects a component or system also affected by this service bulletin, the operator is responsible for obtaining appropriate regulatory agency approval before incorporating this service bulletin. G. Manpower The table below shows an estimate of the task-hours necessary to do this inspection or change one window for each airplane. 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 If the windshield is replaced with same type windshield that uses screws and lugs for window heat power connection. OR Window heat power connection is reassembled (on windshields that uses screws and lugs for window heat power connection). Do a detailed inspection in accordance with Accomplishment Instructions Work Package 1, step 2. and Work Package 2, step 2. Within 150 days or 500 flight hours, whichever occurs earlier, after installation of same windshield type (a). ---- (a) The inital inspection after installing a new window or a new termial screw is to verify that the window heat power connection is correctly made. An improperly installed screw (under torqued or cross threaded) can be identified regardless of the time since installation. If a screw is properly installed and torqued, there is no evidence that it will loosen over time. The inspection steps outlined in this service bulletin should be followed. Refer to either condition "Window heat power connection is reassembled" or "windshield is replaced with same type windshield" in the Compliance Table for inspection requirements.
