(9) Install strip (item 1) over the strip assembly, pressing firmly at the contact area. (10) Remove the strip assembly (items 1, 2 and 3). (11) Counterdrill bonding strip (item 2) to a diameter of 0.1 in (2.5 mm). Disconnect the strips and discard the adhesive tape, remove all remaining adhesive. (12) Enlarge the holes drilled in the strips to a diameter of 0.126 in (3.2 mm). Assemble bonding strips (items 1 and 2) using rivets (item 4). Coat the faces of the strips with covering sealant making a bead at the contour edge with bead sealant. (13) Clean the contact surfaces of the light unit assembly, of the strips, and of the fairing using MEK. (14) Coat the strip assembly (items 2 and 3) with interlaying sealant. (15) Connect and safety connector (4LX) to the light unit. (16) Set the strip assembly and the light unit assembly into place in the fairing and attach the light assembly to the fairing. Smooth out the PR in excess around the strips. FALCON 900EX F900EX -285 January 26, 2015 F900EX -33-08 Revision 1 Page 4 / 14 DASSAULT AVIATION Proprietary Data (17) Use a shim to wedge strip assembly (items 2 and 3) in contact against the fairing’s wall. Allow to cure. (18) Temporarily position the fairing at the fin tip and mark the location of strip (item 3). (19) Strip the paint off the fin tip rib at the location marked for strip (item 3). Protect the stripped area with alodine. (20) Install the retainer, glass cover and sealthe gasket, the lens, and the retainer plate (Refer to IPC fig. 33-40-10-50 , items 190, 180 and 150). (21) Apply a bead sealant around the attaching plate. C. MODIFYING THE WIRING Modify the shield connection in accordance with instructions depicted hereafter and using: • fig. 2 on aircraft with serial numbers 1, 12 and subsequent (modification F900EX M1682 factory applied), • fig. 3 on aircraft with serial numbers 2 through 11 if SB F900EX-25 if applied. Dimension A: • Connector with front extraction: 1.38 in (35 mm). • Connector with rear extraction: 1.97 in (50 mm). Self-soldering sleeves must be staggered at the extremity of the wiring assemblies so as to prevent a bulge on the bundle. INSTALLING SELF-SOLDERING SLEEVES • After stripping the shielded cable and the ground lead wire, unwind the shielding braid of cable without overlapping the shielding strands. • Position the self-soldering sleeve on the stripped part of the cable. • Insert the stripped part of the ground lead wire on the inside of the solder preform. Make sure that the ground lead wire is installed against the guide provided for this purpose. • With hot air or infrared generator equipped with an appropriate reflector, start heating the small diameter of the self-soldering sleeve, then move up to the solder preform until it melts and flows. FALCON 900EX F900EX -285 January 26, 2015 F900EX -33-08 Revision 1 Page 5 / 14 DASSAULT AVIATION Proprietary Data Complete the operation on the large side of the self-soldering sleeve. It is recommended to position the solder preform at a 90° angle maximum in relation to the heat source. The solder must always be visible to the operator. • The insulating sheath of the shielded cable must not be blistered nor burnt. D. RE-ROUTING THE WIRING WITH WIRING ROUTED OVER RIB 2 In accordance with fig. 4: (1) Remove the WHELEN light unit assembly. (2) Drill a 0.19 in (4.9 mm) diameter hole through the rib of the fairing. (3) Install new clamping stud (item 5) on rib 3. (4) Unclamp the wiring from rib 2. (5) Clamp the wiring to rib 3. (6) Connect connector (4LX) to the WHELEN light. (7) Attach the light unit assembly to the fairing. (8) Install the gasket, the glass cover, and the retainer (Refer to IPC fig. 33-40-10-50 , items 180, 190, 260). (9) Apply bead sealant around the retainer. E. RE-ROUTING THE WIRING WITH WIRING ROUTED AROUND THE BACK OF FAIRING In accordance with fig. 5: (1) Remove the WHELEN light unit assembly. (2) Drill a 0.19 in (4.9 mm) diameter hole through the rib 3 of the fairing. (3) Install new clamping stud (item 5) on rib 3. (4) Remove contacts from connector (4LX). (5) Adjust the wiring length for proper re-routing in accordance with fig. 5. (6) Fit the cut wires with new contacts and insert them into connector (4LX). (7) Clamp the wiring to rib 3. (8) Connect connector (4LX) to the WHELEN light. (9) Attach the light unit assembly to the fairing. (10) Install the gasket, the glass cover, and the retainer (Refer to IPC fig. 33-40-10-50 , items 180, 190, 260). (11) Apply bead sealant around the retainer. F. FINAL STEPS (1) Use a permanent ink pen to record the number of this Service Bulletin on "Service Bulletin Compliance" label (item 7). (2) Use interlaying sealant to bond the "Service Bulletin Compliance" label (item 7) to the inner skin of the fairing next to the P/N. (3) Place the fairing on the fin tip, connect connector (322P) and attach the fairing. FALCON 900EX F900EX -285 January 26, 2015 F900EX -33-08 Revision 1 Page 6 / 14 DASSAULT AVIATION Proprietary Data (4) Measure the electrical bonding across the anti-collision light base plate and the reference point located in the mechanic’s servicing compartment (Refer to TASK 20-20-00-910-801). The measured value must not exceed 2 mΩ. (5) Perform the operational test of the upper anti-collision light (Refer to TASK 33-40-00-710-801). G. RECORDING Record compliance with this Service Bulletin in the appropriate aircraft documents. Fill out the card located at the end of the Service Bulletin and mail or fax it to Dassault Aviation or Dassault Falcon Jet, or fill out the electronic Service Bulletin reply form located in the ”Service Bulletin" page on the Falcon portal.
