REASON Outboard slat piccolo tubes have been found deteriorated on some F2000 series aircraft. This situation led, in a few cases, to ice accretion on the outboard slats.
In order to prevent such an unwanted situation, the present Service Bulletin mandates an inspection of the outboard piccolo tubes, and subsequent part replacement as necessary.
C. DESCRIPTION The operation consists in inspecting LH/RH outboard piccolos tubes.
D. COMPLIANCE Mandatory:
• It is anticipated that this Service Bulletin will be rendered mandatory by an EASA Airworthiness Directive.
• As prescribed by the Airworthiness Authorities of the country of registration of the aircraft.
E. APPROVAL The technical content of this document is approved under the authority of DOA nr. EASA.21J.051.

2. ACCOMPLISHMENT INSTRUCTIONS A. PRELIMINARY STEPS
(1) The aircraft must be in the maintenance configuration (Refer to TASK 20-00-00-910-801).
(2) Obey the flight control system maintenance and safety precautions (Refer to TASK 27-00-00-910-801).
(3) Connect the electrical Ground Power Unit (GPU) (Refer to TASK 24-00-00-860-801).
(4) Connect the hydraulic GPU to hydraulic systems 1 and 2 (Refer to TASK 29-00-00-860-801).
(5) Fully extend the slats in normal mode (Refer to TASK 27-50-00-860-802 , paragraph "Extension in Normal Mode").
(6) Inhibit slat deflection (Refer to TASK 27-50-00-860-802 , paragraph "Operation on Slats or Flaps Extended").
¨ B. CHECK OF THE OUTBOARD SLAT PICCOLO TUBE TYPE
(1) On slat side only, disconnect LH and RH outboard telescopic ducts (30DL)/(40DL) (Refer to TASK 30-11-09-900-801).
(2) Using a mirror, check for the absence of weld beads (5-fig. 2) inside the slat outboard slat piccolo tube:
(a) If weld beads are not found, the outboard slat piccolo tube is equipped with a reinforced TE pipe:
1 Using an indelible marker, add suffix "P" to the outboard slat part number.
2 Connect LH and RH outboard telescopic ducts (30DL)/(40DL) (Refer to TASK 30-11-09-900-801).
3 Proceed with step 2.D.
(b) If weld beads are found, the outboard slat piccolo tube is not equipped with a reinforced TE pipe, proceed with step 2.C.
C. INSPECTION
(1) Remove the outboard slat closing rib ( fig. 1).
(a) Remove the bead of Tecsil (1-fig. 1), using cleaner and a plexiglas spatula.
(b) Remove housing (6-fig. 1) with its paddings (7-fig. 1) and the three spacers (8-fig. 1).
(c) Remove all remaining traces of Tecsil using cleaner and a Plexiglas spatula.
(d) Remove closing rib (9-fig. 1) as follows:
• Prepare a screw stowage template for closing rib (9-fig. 1).
• Each screw must be placed, as it is removed, in its corresponding location on the template.
• Remove the six screws (10-fig. 1) and nuts (11-fig. 1), then the three screws (12-fig. 1) and washers (13-fig. 1).
FALCON 2000 F2000 -431 June 06, 2016 F2000 -30-10 Revision 1 Page 4 / 10 DASSAULT AVIATION Proprietary Data
• Remove closing rib (9-fig. 1).
(2) Inspect manifold (1-fig. 2) of the piccolo tube through closing rib (2-fig. 2).
NOTE 1: For this inspection, the borescope (TO-20-010) must have the following features:
• be 1-metre long (3.28 ft),
• have side-view optical device (3-fig. 2),
• save pictures.
NOTE 2: The borescope can be housed in a semi-rigid hose to protect the optical device and enable easy orientation.
Check for cracks and loss of material using a borescope (TO-20-010):
CAUTION: PAY ATTENTION TO CRACKS (1-FIG. 3) AT THE WELD BEADS JUNCTION.
• inspect all the orbital and longitudinal weld beads (4-fig. 2) and (5-fig. 2),
• inspect all the surface (6-fig. 2) of the manifold.
(3) In case of loss of material, replace the outboard slat (Refer to TASK 57-45-13-960-801).
(4) If a crack is found:
(a) Replace the piccolo tube (Refer to TASK 30-11-11-960-801).
(b) Using an indelible marker, add suffix "P" to the outboard slat part number.
(c) Report the crack features: picture, location and length (Refer to RPI 51-00-06) and send the report to structure-repair@dassault-aviation.com.
(5) If no crack is found, no further action is required, proceed with the following steps.
(6) Installation of the closing rib:
(a) Remove all the remaining trace of sealant using cleaner and a Plexiglas spatula.
(b) Position closing rib (9-fig. 1).
(c) Install and tighten the three screws (12-fig. 1) and washers (13-fig. 1), then the six screws (10-fig. 1) and nuts (11-fig. 1) in the locations recorded on the stowage template during removal.
(d) Install housing (F50B134000311B2) (LH side) / (F50B144000311B2) (RH side) (6-fig. 1) with its paddings (F50B134000324B2) (LH side) / (F50B144000324B2) (RH side) (7-fig. 1) and the three spacers (8-fig. 1).
(e) Apply primer 207 on all fasteners:
• in the recesses of the housing (6-fig. 1),
• in the slots of closing rib (9-fig. 1).
(f) Apply bonding T2036 on all fasteners:
• in the recesses of the housing (6-fig. 1),
• in the slots of closing rib (9-fig. 1).
(g) Apply a bead of bonding T2036 along the edge of housing (6-fig. 1).
(h) Smooth out the bead of Tecsil.
