A. Inspection of the Fan Blades, the Stage 1 Booster Vanes and the Spinner Cones
(1) Visually inspect the fan blades and the stage 1 booster vanes at the 6 o'clock position.
(a) If they are wet with oil, replace the engine (Ref. AMM TASK 71-00-00-000-042) and (Ref. AMM TASK 71-00-00-400-042).
(2) Visually inspect the spinner cones.
(a) If they are wet with oil, look for possible damage to spinner cones (Ref. AMM TASK 72-21-00-210-005).
Subtask 79-00-00-210-057-A ** ON A/C NOT FOR ALL (1) Visually inspect the fan blades and the stage 1 booster vanes at the 6 o'clock position.

(2) Visually inspect the spinner cones.
(a) If they are wet with oil, look for possible damage to spinner cones (Ref. AMM TASK 72-21-00-210-005).
B. Inspection of the Drain Mast
(1) Inspect the drain mast for oil leakage.
(2) If you find oil leaks from the drain tubes of the starter pad, the IDG pad, the fuel pump pad or the hydraulic pump pad, do a leak check of the AGB (Ref. AMM TASK 71-00-00-790-001).
(3) If you find oil leaks from the oil tank scupper drain tube, inspect the oil tank filler cap (Ref. AMM TASK 79-11-10-200-002).
Subtask 79-00-00-210-058-A ** ON A/C NOT FOR ALL (1) Inspect the drain mast for oil leakage.
(2) If you find oil leaks from the drain tubes of the starter pad, the IDG pad, the fuel pump pad or the hydraulic pump pad, do a leak check of the AGB (Ref. AMM TASK 71-00-00-790-001).
(3) If you find oil leaks from the oil tank scupper drain tube, inspect the oil tank filler cap (Ref. AMM TASK 79-11-10-200-002).
C. Inspection of the Bottom of the Cowls
(1) Inspect the bottom of the cowls and note any sign of leakage for the visual inspection of the oil system (Ref. AMM TASK 79-00-00-210-003).
(2) Inspect the strut at the bottom of the exhaust nozzle. If any signs of leakage are found, inspect the LPT oil supply and scavenge tubes (Ref. AMM TASK 79-00-00-210-003).
Subtask 79-00-00-210-059-A ** ON A/C NOT FOR ALL (1) Inspect the bottom of the cowls and note any sign of leakage for the visual inspection of the oil system (Ref. AMM TASK 79-00-00-210-003).
(2) Inspect the strut at the bottom of the exhaust nozzle. If any signs of leakage are found, inspect the LPT oil supply and scavenge tubes (Ref. AMM TASK 79-00-00-210-003).
D. Inspection of the centerbody, aft sump area and core exhaust nozzle.
(1) Inspect the centerbody, aft sump area and core exhaust nozzle: oil puddling on the aft sump rear cover, lower area of the center body and core exhaust nozzle must be considered as normal as long as the oil consumption rate is within serviceable limits and the leakage rate from the aft sump flooding drain is within serviceable limits (Ref. AMM TASK 71-00-00-790-002).
5. Close-up(1) Inspect the centerbody, aft sump area and core exhaust nozzle: oil puddling on the aft sump rear cover, lower area of the center body and core exhaust nozzle must be considered as normal as long as the oil consumption rate is within serviceable limits and the leakage rate from the aft sump flooding drain is within serviceable limits (Ref.
