PLANNING INFORMATION A. EFFECTIVITY This Service Bulletin is applicable to FALCON 2000 aircraft with serial numbers 70 through 231. B. REASON Chafing of wire bundle at the bottom of RH electrical cabinet (between Frame 4 and 5) was reported on F2000 aircraft. The wire loom interfered with a metallic (ground) plate of terminal strip (700J) leading to 12 damaged wires and resulting in several flight deck effects. The purpose of this Service Bulletin is to verify the clearance between the metallic plate and the bundle, and if necessary to modify the wire installation in order to get a correct clearance. C. DESCRIPTION The operation consists in: • verifying presence of the metallic plate • checking clearance with the bundle • if necessary cutting out the lower part of the ground plate of terminal strip (700J) and adding an edge protector. D. COMPLIANCE Mandatory as prescribed by the Airworthiness Authorities of the country of registration of the aircraft. E. APPROVAL This Service Bulletin covers DASSAULT AVIATION modification FALCON F2000 M3889 that has been approved under the authority of DOA nr. EASA.21J.051.

GENERAL AND SAFETY PRECAUTIONS (1) Obey the general maintenance and safety precautions (Refer to TASK 20-00-00-910-801). (2) Obey the general electrical instructions: (a) when mechanical retrofit and/or modification operations are performed on the aircraft, take special care to protect the wiring in order to prevent metal chips (or burrs) from penetrating into the wire bundles, since they could eventually damage the insulation sheathing of the wires. Whenever possible, it is recommended that the wiring be removed from the work area. If that is not possible, it is absolutely necessary to protect the wiring, (b) due to the risk of damaging the wire insulation, it is prohibited to blindly drill holes through a box structure containing wiring, (c) electric and electronic equipment should be removed and installed as per the recommendations in Standard Practices, (Refer to TASK 20-00-00-910-801). (d) visually inspect the work area for particles or debris, then vacuum-clean. The blowing of compressed air is prohibited since it could move metal chips to inaccessible areas. (e) check that all connections are properly protected to ensure proper insulation, and that markings are visible and appropriate. (3) Obey the Structural Repair Manual and Standard Practices procedures for the following operations: • drilling (Refer to RPI 51-40-03), • basic sealing methods (Refer to TASK 20-32-00-390-801). B. PRELIMINARY STEPS (1) The aircraft must be in the maintenance configuration (Refer to TASK 20-00-00-910-803). (2) Remove and/or open the panels, doors, equipment and components necessary to get access to the working area. (3) In the bottom of RH electrical cabinet, perform a visual inspection to see if there is a terminal strip (700J) with metallic plate (ground plate) (fig. 2): • if there is a metallic plate, go to step 2.C., • if there is no metallic plate, no further action is required, go to step 2.D. C. PROCEDURE Refer to fig. 1, fig. 2, fig. 3 and fig. 4 (1) In the bottom of RH electrical cabinet ( fig. 3 and fig. 4): NOTE: Terminal strip (700J) and its ground plate are installed on RH stringers 10-11 bracket. (a) in case of interference, check the wiring bundle (Refer to TASK 20-90-00-200-801), (b) check that the clearance between the ground plate of terminal strip (700J) and the wiring bundle is > 12 mm (0.47 in.) (fig. 3 and fig. 4): • if the clearance is ≥ 12 mm (0.47 in.), no further action is required, go to step 2.D., FALCON 2000 F2000 -436 September 28, 2017 F2000 -24-24 Initial issuance Page 4 / 10 DASSAULT AVIATION Proprietary Data ### Page 7 • if the clearance is < 12 mm (0.47 in.), go to the next step, (c) measure a clearance of 15 mm (0.59 in.) between the ground plate and the wiring bundle, and make a mark (cutting line) on the ground plate (fig. 4), NOTE: The value of 15 mm (0.59 in.) = 12 mm (0.47 in.) + 3 mm (0.12 in.) (U protector). (d) identify the location of the ground connections on the ground plate, (e) remove the ground connections ( fig. 4 ) installed on the ground plate (Refer to TASK 20-20-00-900-801), (f) remove terminal strip (700J) and its ground plate ( fig. 3) (2) Separate terminal strip and ground plate. (3) Modify the ground plate ( fig. 4): (a) cut out the lower part of ground plate by respecting the mark previously made and apply alodine (Refer to TASK 20-60-00-370-801), (b) install U protector (1-fig. 4) on the ground plate and verify that clearance of 12 mm (0.47 in.) between ground plate and wiring bundle is always respected, (c) if necessary, adapt cutting according to clearance (12 mm (0.47 in.) minimum) to be obtained , NOTE: The cutting describe on fig. 4, is an example. The cutting can be modified following the bundle position. (d) if the lower hole (Hole E-fig. 4 ) was occupied and that it is impossible to install the ground connections, drill a new hole (Hole F-fig. 4 ) diameter in accordance with lug and protect with alodine (Refer to TASK 20-60-00-370-801), (e) install U protector (1-fig. 4 ) on ground plate with interlaying sealant (Refer to TASK 20-32-00-390-801), (f) write " SBF2000-436 APPLIED " near the part original marking and protect with vinyl varnish, (4) Install terminal strip (700J) and its ground plate modified at the same location (Refer to paragraph 2.C.(1)(f)). (5) Install ground connections on ground plate (Refer to TASK 20-20-00-900-801). D. FINAL STEPS (1) Install and/or close panels, doors, components and equipment removed and/or opened previously (paragraph 2.B.(2)). E.
