1. PLANNING INFORMATION
A. EFFECTIVITY
This Service Bulletin is applicable to F2000 aircraft with serial numbers 1 thru 231 that have not
performed the general visual inspection of the wings (Refer to TASK 57-00-00-210-801), included in
Aircraft Maintenance Manual Revision 41 - Update 2, after April 13, 2021.
B. REASON
Occurrences of wing anti-icing leaks in the wing leading edge, due to incorrect installation of Wiggins
coupling on the wing anti-icing system or due to the detachment of the pressure switch line from the
wing anti-icing pipe, were observed in service.
These conditions, if not detected and corrected, can result in degraded wing anti-icing performance.
The purpose of this Service Bulletin is to inspect the wing anti-icing Wiggins couplings and pipes.
C. DESCRIPTION
The operation consists in checking the wing anti-icing Wiggins couplings and pipes for correct
conditions on LH and RH sides.
D. COMPLIANCE
Mandatory 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 the DOA ref. 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.

2. ACCOMPLISHMENT INSTRUCTIONS
A. PRELIMINARY STEPS
(1) Obey the general maintenance and safety precautions (Refer to TASK 20-00-00-910-801).
(2) The aircraft must be in the maintenance configuration (Refer to TASK 20-00-00-910-803).
(3) Fully extend the slats (Refer to TASK 27-50-00-860-802  - "EXTENSION IN NORMAL MODE")
(4) Inhibit slat deflection (Refer to TASK 27-50-00-860-802  - "EXTENSION IN NORMAL MODE" )
"OPERATION ON SLATS OR FLAPS EXTENDED").
(5) De-energize the aircraft systems (Refer to TASK 24-00-00-860-801).
(6) Remove:
• wing inboard leading edge access panel (512BT) / wing inboard leading edge access panel
(612BT),
• wing lower surface outboard leading edge access panel No. 1 (522AB) / wing lower surface
outboard leading edge access panel No. 1 (622AB).
B. PROCEDURE
CAUTION: THE CLAMP MUST ROTATE FREELY AROUND THE TWO FERRULES.
(1) Check the wing anti-icing Wiggins couplings ( 1-fig. 1) on LH and RH sides for:
• condition,
• correct installation,
• deformation,
• leakage or signs of overheating,
• free rotation of the clamp around the two ferrules.
(2) In case of findings, replace or re-install the affected wing anti-icing Wiggins coupling with new
seals (Refer to TASK 20-41-00-900-801).
(3) Check for condition the thermal lagging of all wing anti-icing pipes (traces of abnormal leakage,
overheating or degradation of the thermal lagging) on LH and RH sides:
• Pay special attention at junction between wing anti-icing pipes (1-fig. 2) and wing anti-icing
pressure switches (L50DL)/(R50DL) pipes (2-fig. 2).
• In case of doubt about a possible leakage, perform a leak check of the wing anti-icing
system (Refer to TASK 30-10-00-790-801).
(4) In case of findings, replace the affected wing anti-icing pipes (Refer to TASK 30-11-13-900-801).
C. FINAL STEPS
(1) Install the access panels and doors removed previously.
(2) Return the aircraft to the initial configuration.
