A. Do this test:
(2) Let the engine become stable at MIN IDLE for three minutes.
(3) Make sure that the parameters are in the limits of operation.
(4) Make sure that there are no incorrect status or ECAM warning messages.
(5) Make a record of any fault message that you see.
(6) Do a shutdown of the engine by the Discontinued Start, Restart and Shutdown Procedure (Ref. AMM TASK 71-00-00-710-018).
(7) Set each channel and do a check of the CFDS fault messages.
(8) Refer to the Trouble Shooting Manual and do the necessary maintenance.
Subtask 71-00-00-210-092-A ** ON A/C NOT FOR ALL NOTE: A Flex Temperature must not be selected to perform this test.
NOTE: For general information refer to Engine Operation Limits, Guidelines, and Special Procedures (Ref. AMM TASK 71-00-00-860-010).
You can use this test to do a check for correct operation of the EEC.
The Operational Test of the EEC (Ref. AMM TASK 73-22-34-710-040) is usually done before this test. This will let you make sure of correct EEC operation.
This test can be done at the same time as test No.3, the Idle leak check (Ref. AMM TASK 71-00-00-710-012).
(1) Start the engine by the Normal Engine Automatic Start Procedure (Ref. AMM TASK 71-00-00-710-043) or the Normal Engine Manual Start Procedure (Ref. AMM TASK 71-00-00-710-047). You can use this test to do a check for correct operation of the EEC.

(7) Set each channel and do a check of the CFDS fault messages.
(8) Refer to the Trouble Shooting Manual and do the necessary maintenance.
B. Do an inspection of the turbine exhaust case for oil.
(1) Visually inspect the turbine exhaust case for oil that came out the No.4 bearing weep tube port (Ref. AMM TASK 72-50-00-200-010).
(2) If there is oil, do the procedure to dry out the high presssure turbine after oil contamination (Ref. AMM TASK 71-00-00-700-013).
