PLANNING INFORMATION A. EFFECTIVITY This Service Bulletin is applicable to all FALCON 10 aircraft that have implemented Service Bulletin F10-333. B. REASON New wing anti-icing system flexible hoses were introduced by Service Bulletin F10-333. Since then, field reports revealed early failures of the outboard hoses before their end of life. This could result in compromising the correct operation of the wing anti-icing system. C. DESCRIPTION The Service Bulletin is divided into two sections: • Section F10-338-1: Inspection of the outboard anti-icing hoses for damage The operation consists in: • Checking the hoses according to acceptance criteria, • replacing them with new ones, if necessary, • filling out the inspection report and sending it back to Dassault Aviation. • Section F10-338-2: Inspection of the inboard anti-icing hoses for damage The operation consists in: • Checking the hoses for any kink, • replacing them with new ones, if necessary, • filling out the inspection report and sending it back to Dassault Aviation. D. COMPLIANCE First section is mandatory as prescribed by the Airworthiness Authorities of the country of registration of the aircraft. Second section can be performed at your convenience (e.g. when applying first section of this Service Bulletin). E. APPROVAL The technical content of this document is approved under the authority of DOA nr. EASA.21J.051. F. LABOR Estimated labor-hours: Refer to Service Bulletin Commercial Summary. NOTE: These labor-hours only concern the work described in this Service Bulletin and do not include other maintenance work that may be performed on this occasion.

SECTION F10-338-1: INSPECTION OF THE OUTBOARD ANTI-ICING HOSES FOR DAMAGE (MANDATED BY AN AIRWORTHINESS DIRECTIVE) A. PRELIMINARY STEPS (1) Obey the general maintenance and safety precautions, as per AMM procedure (Task 20-00-05-2). (2) Aircraft on wheels in maintenance configuration. (3) Connect the electrical Ground Power Unit (GPU). (4) Connect the hydraulic GPU to hydraulic system 1. (5) Install the safety fences and warning lights. (6) Remove the lower access doors (522AB) and (622AB) to access outboard hoses. (7) Extend the slats as follows: (a) Energize the aircraft systems with the electrical GPU. (b) Pressurize hydraulic system 1 from the hydraulic GPU. (c) In the cockpit, on slat control box (63C), set the slat control lever to "SLATS". (d) Cut off and drop the pressure in hydraulic system 1. (e) De-energize the aircraft systems. (f) Disengage the "STALL1"/"STALL2" circuit breakers and secure them with circuit breaker lockouts. B. INSPECTION OF THE OUTBOARD ANTI-ICING HOSES CAUTION: FOLLOWING INSPECTION, TAKE PICTURES OF DAMAGE (IF ANY) AND ATTACH IT TO THE INSPECTION REPORT (FIG. 5). NOTE: Procedure as described below is to be done at L/H and R/H wings. (1) Check the hose for traces of interference with greasing nipple ( fig. 1): (a) In case of chafing mark(s), check the hose for kinks (refer to step 2.B.(2)). (b) If the hose is torn or cut, replace it (refer to step 2.C.). (c) Fill out the inspection report ( fig. 5). (2) Check the outboard hoses for kinks at ends A and B ( fig. 2 and fig. 3) as follows: (a) Check for kink(s) at end A ( fig. 2) and end B (fig. 3): 1 If kink(s) are not acceptable, replace the hose (go to step 2.C.). 2 Otherwise, perform a retraction/extension of the slats in slow mode (next steps (b) and (c) ). (b) Engage the "STALL1"/"STALL2" circuit breakers. (c) Energize the aircraft systems with the electrical GPU. FALCON 10 F10 -338 February 20, 2019 F10 -30-28 Initial issuance Page 3 / 14 DASSAULT AVIATION Proprietary Data ### Page 6 (d) Retract the slats in slow mode, as follows: NOTE: The goal of this operation is to evaluate the possible change of depth of the kinks, during slat motion. 1 In the cockpit, on slat control box (63C), set the slat control lever to "CLEAN". 2 Pressurize hydraulic system 1 from the hydraulic GPU, by a gradual increase of pressure starting at 0 bar (0 psi), until the slats move very slowly, without exceeding 50 bar (725 psi): • During slat motion, check the kink(s) for changes in depth at ends A and B. • If kink(s) is/are not acceptable, replace the hose (go to step 2.C.). 3 Cut off and drop the pressure in hydraulic system 1. (e) Extend the slats in slow mode, as follows: NOTE: The goal of this operation is to evaluate the possible change of depth of the kinks, during slat motion. 1 In the cockpit, on slat control box (63C), set the slat control lever to "SLATS". 2 Pressurize hydraulic system 1 from the hydraulic GPU, by a gradual increase of pressure starting at 0 bar (0 psi), until the slats move very slowly, without exceeding 50 bar (725 psi): • During slat motion, check the kink(s) for changes in depth at ends A and B. • If kink(s) is/are not acceptable, replace the hose (go to step 2.C.). 3 Cut off and drop the pressure in hydraulic system 1. (f) De-energize the aircraft systems. (g) Disengage the "STALL1"/"STALL2" circuit breakers and secure them with circuit breaker lockouts. (3) Fill out the inspection report ( fig. 5). C. REPLACEMENT OF THE OUTBOARD ANTI-CING HOSE (IF NECESSARY) (1) Make sure that the aircraft systems are de-energized and the pressure is dropped in hydraulic system 1. (2) Remove the hose as per AMM procedure (Task 30-10-04-4). (3) Perform a dimensional check at the outboard fixed leading edge box, in order to get feedback to improve the design: • Measure distance X1 (L/H slat) and/or X2 (R/H slat), between the fixed pipe end-fitting and the outer face of the roller holder (fig. 4). (4) Record the value(s) into the inspection report ( fig. 5). (5) Install new hose as per AMM procedure (Task 30-10-04-4). NOTE: Refer to kit SBF10-0338A for P/N of hose. FALCON 10 F10 -338 February 20, 2019 F10 -30-28 Initial issuance Page 4 / 14 DASSAULT AVIATION Proprietary Data ### Page 7 D. FINAL STEPS (1) Send the inspection report ( fig. 5) to CommandCenter@dassault-aviation.com. (2) If L/H and R/H outboard anti-icing hose(s) has/have been replaced: • Check hose(s) for correct installation and for leaks as per AMM procedure (Task 30-10-04-4). (3) Return the aircraft to initial configuration: (a) Re-install the lower access doors (522AB) and (622AB). (b) Remove the safety fences and warning lights. (c) Disconnect the hydraulic GPU.
