C. Get Access
(1) Open the left fan-cowl door :
(a) FOR [1000EM2] (ENGINE-2)
open the door 447AL (Ref. AMM TASK 71-13-00-010-040).

(3) Put the ACCESS PLATFORM 2M (6 FT) - ADJUSTABLE in position at the engine.

4. Procedure
Subtask 29-13-43-611-052-A ** ON A/C NOT FOR ALL

A. Servicing of the Engine Pump Case-Drain Filter
(1) Cut and remove the lockwire from the filter bowl (10).
(2) Remove the filter bowl (10) from the filter head.
(3) Remove and discard the filter element (5) from the filter bowl (10).
(4) Examine the filter element in order to find the causes of contamination.
If you find metal particles in the filter element you must check the associated hydraulic system after operation in the engine pump in possible cavitation condition (Ref. AMM TASK 29-00-00-280-006).
(5) Put a new AIPC 29-13-43-02-030 FILTER ELEMENT (5) into the filter bowl (10).
(6) Install the filter bowl (10) into the filter head and tighten it with your hand.
(7) Lock the filter bowl (10) to the filter head with corrosion resistant steel lockwire dia 0.8 mm (0.032 in.).
(8) Examine the filter clogging indicator. If the red clogging indicator has come out, set it to the operational position as follows:
(a) Cut and remove the safety wire, then remove the transparent cap.
(b) Push the red clogging indicator in.
(c) Install the transparent cap.
(d) Lock the cap with corrosion resistant steel lockwire dia 0.8 mm (0.032 in.).
(9) Remove the container.

B. Operational Test
(1) Pressurize the Yellow hydraulic system
(Ref. AMM TASK 29-10-00-863-002).
(2) Do an operational test of the Yellow hydraulic system (Ref. AMM TASK 29-13-00-710-002).
(3) During the dry motoring of engine 2, make sure that:

There are no leaks from the case drain filter,
The clogging indicator of the filter is not out.

(4) Make sure that the level of hydraulic fluid in the Yellow reservoir is correct.
If necessary, fill the reservoir (Ref. AMM TASK 12-12-29-611-001) or (Ref. AMM TASK 12-12-29-611-002).

5. Close-up
