(F2000EX, F2000EX EASy, F2000LX, F2000LXS, F2000DX, F2000S) equipped with outboard slat
part number without the suffix "P" (see table below):

B. 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.

¨
B. CHECK OF THE OUTBOARD SLAT PICCOLO TUBE TYPE
(1) On the slat 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 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)
