3. Placard (texte MEL) :
Apply sticker/placard adjacent to the Leading Edge Flap/Slat Position panel, and, if indication for one
slat inoperative fabricate and affix a placard stating "INOP - VISUALLY CONFIRM POSITION" adjacent
to annunciator panel.
4. Journey log / other instructions (texte MEL) :
Print the following information in the journey log sheet.
• Forward Panel Lights or Annunciator Panel Inoperative:
LEADING EDGE FLAP/SLAT POSITION LIGHT SYSTEM INOP
• One Leading Edge Slat Indication Inoperative:
_____LEADING EDGE SLAT INDICATION INOP - VISUALLY CONFIRM POSITION
5. Respecter toutes les restrictions du MEL — ne pas en inventer.
(O) OPERATIONS PROCEDURES — texte MEL :
27-04-02-03: Leading Edge Slat indications
With forward position indicator lights inoperative and one SLATS annunciator panel light inoperative:
1. Verify leading edge slat position for the inoperative indication before each takeoff and landing.
2. Limit airspeed
a) At or below FL 200, limit airspeed to 300 KIAS.
b) Above FL 200, limit airspeed to 0.65 Mach
NOTE: Refer to Section 4 of the Airplane Flight Manual for the Cruise Maneuvering Capability
Chart for maintaining minimum maneuvering speeds.
CAUTION:
FLIGHT CREW TO BE AWARE OF LOW SPEED BUFFET LIMITATIONS.
(M) MAINTENANCE PROCEDURES — texte MEL (maintenance ; l’équipage vérifie que c’est fait) :
27-04-02B: Forward Panel Lights
With forward position indicator lights inoperative (AMM 27-00-00/901):
1. Cycle the flaps.
2. Verify that the LE DEVICES annunciator panel (P5) operates normally during flap extension and
retraction.
NOTE: If an annunciator panel TRANSIT light fails to illuminate while the corresponding device
is in motion, then this light must be considered inoperative.
3. Remove the bulbs from the associated forward position indicator light(s) on the center instrument
panel, P2.
4. Use this data to make a placard and put it adjacent to the LE DEVICES annunciator panel:
For -800SFP:
a) Flap positions 1 thru 5:
1. All slats in EXT position
2. LE flaps extended
b) Flap positions 10 thru 40:
1. All slats in FULL EXT position
2. LE flaps extended
Continued…
27-04-02-03: Leading Edge Slat indications
With forward position indicator lights inoperative and one SLATS annunciator panel light inoperative
(AMM 27-00-00/901):
1. Perform Flaps cycle by extending and retracting the TE and LE flaps.
2. Verify that the remaining LE DEVICES annunciator panel (P5) lights operate normally during flap
extension and retraction.
NOTE: If an annunciator panel TRANSIT light fails to illuminate while the corresponding
device is in motion, then this light must be considered inoperative.
3. After verification of a single inoperative LE Slat Position light, determine and record which TE Flap
position settings cause this failure.
a) If faulty indication on overhead annunciator panel can be replicated on the ground, record
which TE Flap position settings causes this failure.
b) If faulty indication on overhead annunciator panel cannot be replicated on the ground, use
FSEU BITE to determine if an FSEU input has been recently faulty.
1. If FSEU BITE (Flight Leg 0) indicates fault message codes 27-81200 through 27-81223 or
27-81225 through 27-81236, open and collar the Stall Warning Asymmetry Mode circuit
breaker on the P18-2 Panel.
2. If FSEU BITE does not yield one of these fault codes because the faulty overhead
indication light(s) flashes ON/OFF for an instant such that the fault does not latch, first
confirm that the applicable slat is stationary in the position where the intermittent
indication was observed, then open and collar the Stall Warning Asymmetry Mode circuit
breaker.
4. Remove the bulbs from the applicable inoperative light(s) on the center instrument panel, P2-2.
Attach an INOP placard to this light.
5. Use the following information to make a placard and install it adjacent to the LE Device
Annunciator Panel P5-12:
For -800SFP:
a) Flap positions 1 thru 25:
1. All slats in EXT position.
2. LE flaps extended.
b) Flap positions 30 and 40:
1. All slats in FULL EXT position.
2. LE flaps extended.
6. Using the information recorded in step 3, set flaps to the position which produces the faulty
indication.
7. Verify that the leading edge and trailing edge devices are in the correct position.
Continued…
8. Verify normal operation of both Stall Warning Systems:
For -800SFP:
NOTE: If the inoperative slat indication occurs at more than one flap position, repeat the
procedure to verify normal operation of both Stall Warning Systems at Flaps 0,
Flaps 1 and Flaps 30.
a) Verify that hydraulic system B pressure is between 2900 and 3100 psi.
b) While monitoring the control column for stick shaker operation, push and hold STALL
WARNING TEST NO. 1 and NO. 2 switch on the stall warning test module (P5 Overhead
Panel).
c) If both stick shakers fail to operate normally, open and collar the Stall Warning Asymmetry
Mode circuit breaker on the P18-2 Panel and repeat the test in Step b.
9. If the stick shaker tests are not normal, airplane cannot be dispatched.
Consult the FIM Section 27 to isolate the fault and perform the appropriate corrective action.
MAINTENANCE NOTE:
Advise Dispatch. Flight Planning may be affected.
