## Description **Group 1: 1. CONCURRENT REQUIREMENTS**  None. **2. BACKGROUND** Boeing found the left wing spoiler 4 electro-mechanical actuator power feeder wire W801182 does not have enough separation to the flap variable camber trim unit support bracket outboard end when the spoiler is deployed. This service bulletin provides instructions to measure the separation between the wire and the bracket outboard end with the spoiler in the deployed position. If the measurement does not meet the minimum separation requirement, this service bulletin provides instructions to inspect and adjust the wire. If the wire does not have enough separation to the bracket outboard end when the spoiler is deployed, the wire could be damaged by contact with the bracket which could result in an electrical short and potential loss of several functions essential for safe flight. Boeing Service Related Problem (SRP) 787 SRP-27-244 is related to this service bulletin.This table is provided to operators for planning purposes only.

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 Data Module SB B787-A-27-00-0024-00A932A-D, Paragraph 10., References, for definition of the acronyms. 2. Obey all of the warnings and cautions given in the specified manual sections. 3. Unless shown differently, these dimensions and tolerances are used: – Linear dimensions are in inches – Tolerance on linear dimensions, other than rivet and bolt edge margins, is plus or minus 0.03 inch – Tolerance on rivet and bolt edge margin is plus or minus 0.05 inch – Angular tolerance is plus or minus 2 degrees – Hole dimensions for standard solid rivets and fasteners are in SRM Chapter 51 – Torque Values: – Values for structural fasteners are given in 787 Structural Repair Manual, Chapter 51. – Values for airframe maintenance tasks are included in Chapter 20 of 787 Airplane Maintenance Manual (AMM). – Values for electrical maintenance tasks are included in Chapter 20 of Standard Wiring Practices Manual (SWPM).– Values for engine maintenance tasks are included in Chapter 70 of 787 Airplane Maintenance Manual (AMM).– Non-standard torque values for maintenance tasks are included in the applicable installation step. 4. Refer to the SWPM 20-10-11 and SWPM 20-10-12 for the wire installation procedures, and SWPM 20-10-19 for the wire separation requirements, as accepted procedures. 5. The necessary conditions for selection of clamp type and size are included in SWPM 20-10-12. If any wire bundle support clamp specified in this service bulletin does not make a correct fit on the wire bundle, refer to SWPM 20-10-12 as an accepted procedure to select a clamp that fits correctly. 6. 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 madeunder normal available lighting conditions such as daylight, hangar lighting, flashlight or droplight 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. 7. 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 "in accordance with" are included in the instruction, the procedure in the Boeing document must be used.
