A. IF YOU CHOOSE TO PERFORM THIS CHECK WITH HYDRAULIC SUPPLY FROM A GROUND POWER UNIT (1) PRELIMINARY STEPS (a) The aircraft must be in the maintenance configuration (Refer to TASK 20-00-00-910-801 ). (b) Obey the flight control system maintenance and safety precautions ( Refer to TASK 27-00-00-910-801 ). (c) Energize the aircraft systems from the electrical GPU (Refer to TASK 24-00-00-860-805 ). (d) Make sure that the park brake handle ( 804GC ) is pulled. (e) Make sure that the slats/flaps control lever (1-fig. 1) of the SFAU ( 9001CF ) is set to “SF 0”. (f) On maintenance panel ( 1010TP ) , set the "TEST E2" switch ( L511CZ )and the "TEST E1" switch ( R511CZ ) to the ON position (fig. 2 ). (g) Pressurize the three hydraulic systems (Refer to TASK 29-00-00-860-803 ). (h) Remove the four multi-function probe covers (KPC3-780-45). (i) On the overhead panel ( 5000PM ) , set the "PROBE 1+2" pushbutton ( R9810PM ) , the "PROBE 3" pushbutton ( R9820PM )and the "PROBE 4" pushbutton ( R9830PM ) to ON ( fig. 1 ). (j) Wait for one minute to be in the FCS normal mode. (2) PROCEDURE (a) On the LH front SPDB ( L1000PM ) , disengage the "SFC LF E3" circuit breaker ( 213CZ ) (fig. 3 ). (b) Check that the " FCS: SLATS INB EXTEND FAIL " CAS message is displayed. (c) Set the slats/flaps control lever (1-fig. 1) of the SFAU ( 9001CF ) to “SF1”. (d) Check that the middle slats ( L9501CM ) , ( L9501CM )and the outboard slats ( L9502CM ), ( R9502CM ) move to the extended position. (e) Check that the " FCS: SLATS INB EXTEND FAIL "CAS message and " FCS: ALTN LAWS ACTIVE " CAS message are displayed. NOTE: An irrelevant " FCS: NO DISPATCH "CAS message is displayed when the " FCS: ALTN LAWS ACTIVE " appears. It does not need specific monitoring. (f) Set the back-up slat control switch (2-fig. 1) of the SFAU ( 9001CF )to the extension position (guard up). (g) Make sure that the middle slats ( L9501CM ) , ( L9501CM )and the outboard slats ( L9502CM ), ( R9502CM ) stay extended. NOTE: If the middle and outboard slats are retracted, the test is failed. In this case, stop the procedure and refer to paragraph 2.A.4. (h) Check the following CAS messages: • " FCS: SLATS M+O EXTEND FAIL " is notdisplayed,
