__________________
A. Test
(1) Do the operational test of the probe ice protection (Ref. AMM TASK 30-31-00-710-001).
4. Fault Isolation
_______________
A. If the test gives the maintenance message R STATIC PROBE 8DA3:
- do a check of the resistance between pin 2 and pin 1.
(1) If the resistance is more than 13 ohms (open circuit) or less than 10 ohms (short circuit).
(a) Replace the PROBE-R STATIC, 3 (8DA3), (Ref. AMM TASK 34-11-16-000-001) and (Ref. AMM TASK 34-11-16-400-002).
(2) If the resistance is between 10 ohms and 13 ohms:
(a) Replace the PHC-3 (6DA3), (Ref. AMM TASK 30-31-34-000-002) and (Ref. AMM TASK 30-31-34-400-002).

(b) If the fault continues:
- do a check and repair the wiring from the PHC 3 (6DA3) to the R static probe 3 (8DA3) pin A/E to pin 2 (Ref. ASM 30-31/03).
B. Do the operational test given in Para. 3.

A. Test
(1) Do the operational test of the probe ice protection (Ref. AMM TASK 30-31-00-710-001).
4. Fault Isolation
_______________
A. If the test gives the maintenance message AOA SENSOR 3FP3:
- disconnect the connector from the angle of attack sensor 3 (3FP3) and do a check of the resistance between pin A/<J and pin A/<G.
(1) If the resistance is more than 110 ohms (open circuit) or less than 20 ohms (short circuit):
(a) Replace the SENSOR-ANGLE OF ATTACK, 3 (3FP3) (Ref. AMM TASK 34-11-19-000-001) and (Ref. AMM TASK 34-11-19-400-001).
(2) If the resistance is between 20 ohms and 110 ohms:
(a) Replace the PHC-3 (6DA3) (Ref. AMM TASK 30-31-34-000-002) and (Ref. AMM TASK 30-31-34-400-002).
