Subtask 33-43-00-810-050-A
A. If during the operational test when you set the EXT LT/RWY TURN OFF switch (2LC) to the ON position, the Right runway-turn-off light does not operate correctly:
NOTE: For the GLS LEDs technology, if there are more than two LEDs that do not come on, Airbus does not make sure that sufficient lighting or a minimum of the same as obtained with the sealed beam lights will come on.
  • Do a check of the right runway-turn-off lighting/external light circuit- breaker (1LC2) status.
   (1) If the circuit breaker is closed:
  • Do a check for continuity between the right runway-turn-off lighting/external light circuit-breaker (1LC2) and pin A/A of the right runway-turn-off light (3LC2).
     (a) If there is continuity:
  • Do a check for 115VAC between pin A/A and pin A/B of the right runway-turn-off light (3LC2).
       1 If there is 115VAC:
         a For GLS LEDs Light Unit technology:
         b For ECE Light unit with incandescent lamp technology and Honeywell Light unit with halogen lamp technology:
- Remove the Lamp from the right runway-turn-off light (3LC2) AMM 33-43-11-960-002,
  • Do a check for 28VAC at the lamp socket.
    * If there is 28VAC at the lamp socket:
    ** For ECE Light unit with incandescent lamp technology:
  • Replace the Lamp of the right runway-turn-off light (3LC2) AMM 33-43-11-960-002.
    ** For ECE Light unit and Honeywell Light unit with halogen lamp technology:
  • Replace the Halogen Bulb of the right runway-turn-off light (3LC2) AMM 33-43-11-960-001.
    * If there is no 28VAC at the lamp socket:
  • Replace LT-RUNWAY TURNOFF, R [3LC2] AMM 33-43-11-000-001 and AMM 33-43-11-400-001.
       2 If there is no 115VAC:
  • Repair the wiring from pin A/B of the right runway-turn-off light (3LC2) to the ground terminal ASM 334301.
     (b) If there is no continuity:
  • Replace RELAY-PWR SPLY, RWY TURN OFF LT (6LC) AIPC 334308.
       1 If the fault continues:
  • Do a check for 115VAC at pin A/A2 of the power supply relay (6LC).
         a If there is 115VAC:
  • Repair the wiring between the power supply relay (6LC) pin A/A1 and the pin A/A of the right runway turn off light (3LC2) ASM 334301.
         b If there is no 115VAC:
  • Replace the C/B-LIGHTING/EXT LT/RWY TURN OFF/R [1LC2] .
    * If the fault continues:
    - Repair the wiring between pin A/A2 of the power supply relay (6LC) and the right runway-turn-off lighting/external light circuit-breaker (1LC2) ASM 334301.
   (2) If the circuit breaker is open:
     (a) If the fault continues:
Subtask 33-43-00-710-051-A
B. Do the test given in Para. 3.
