3. Job Set-up
Subtask 24-21-51-941-075-A ** ON A/C NOT FOR ALL

A. Safety Precautions
(1) On the center pedestal, on the ENG panel 115VU:
(a) Put a WARNING NOTICE(S) to tell persons not to start the engine.
(2) Make sure that the engine 1(2) shutdown occurred not less than 5 minutes before you do this procedure.
(3) On the overhead maintenance panel 50VU:
(a) Make sure that the ON legend of the ENG/FADEC GND PWR/1(2) pushbutton switch is off.
(b) Put a WARNING NOTICE(S) to tell persons not to energize the FADEC 1(2).

Subtask 24-21-51-010-106-A ** ON A/C NOT FOR ALL

B. Get Access
(1) Open the fan cowl doors (Ref. AMM TASK 71-13-00-010-010):
(a) FOR [1000EM1] (ENGINE-1)
437AL 438AR,
(b) FOR [1000EM2] (ENGINE-2)
447AL 448AR.

4. Procedure
Subtask 24-21-51-210-053-A ** ON A/C NOT FOR ALL

A. Visual Inspection of the Differential Pressure Indicator (DPI)
(1) Do a check of the IDG-filter differential-pressure indicator (Ref. AMM TASK 24-21-51-200-011).

Subtask 24-21-51-210-054-A ** ON A/C NOT FOR ALL

B. Visual Inspection of the IDG Oil Level
(1) Let the IDG oil become stable for a minimum of five minutes after the engine shutdown.
(2) Look at the IDG oil-level sightglass:

NOTE: The IDG oil temperature is shown on the ECAM "ELEC SD" page. If the oil temperature is less than 49 DEG.C (120 DEG.F), the oil is cold. If the oil temperature is equal to or more than 49 DEG.C (120 DEG.F), the oil is hot.

NOTE: An internal oil consumption of 1 cc is permitted for each flight hour or when the engines operate.

(a) If the oil is cold and the oil level is:
1 Immediately above the lower limit of the yellow band (because of the aircraft ramp angle), it is not necessary to drain the IDG oil.
2 In the yellow band, drain the oil to adjust the oil level (Ref. AMM TASK 12-13-24-680-010).
3 Below the green band, add oil to adjust the oil level (Ref. AMM TASK 12-13-24-612-011).
4 In the red band (and if you think that there is an IDG oil leak or an unusual consumption):
a Do a visual inspection of the IDG for oil leaks (Ref. AMM TASK 24-21-00-210-048).
b Do the IDG oil leak-test TSM 24-21-00-810-849.
c Do the unusual IDG oil-consumption procedure TSM 24-21-00-810-817.
(b) If the oil is hot and the oil level is:
1 Between the middle of the green band and the top of the yellow band, it is not necessary to do the IDG oil servicing.
2 Above the yellow band, drain the oil to adjust the oil level (Ref. AMM TASK 12-13-24-680-010).
3 Below the middle of the green band, add oil to adjust the oil level (Ref. AMM TASK 12-13-24-612-011).
4 In the red band (and if you think that there is an IDG oil leak or an unusual consumption):
a Do a visual inspection of the IDG for oil leaks (Ref. AMM TASK 24-21-00-210-048).
b Do the IDG oil leak-test TSM 24-21-00-810-849.
c Do the unusual IDG oil-consumption procedure TSM 24-21-00-810-817.
