Subtask 71-00-00-720-083-A ** ON A/C NOT FOR ALL

A. Preparation before the test:

WARNING: BEFORE YOU START THE ENGINE, MAKE SURE THAT:

YOU OBEY ALL THE ENGINE SAFETY PRECAUTIONS
YOU DO ALL THE OPERATIONS NECESSARY TO PREVENT MOVEMENT OF THE AIRCRAFT.

IF YOU DO NOT OBEY THESE PRECAUTIONS, INJURY TO THE PERSONNEL AND DAMAGE TO THE AIRCRAFT AND/OR EQUIPMENT CAN OCCUR.

(1) Obey the safety precautions and the engine operation limits and guidelines procedure (Ref. AMM TASK 71-00-00-910-804) and (Ref. AMM TASK 71-00-00-910-803).
(2) Do the preparation for a pneumatic leak test (Ref. AMM TASK 71-00-00-790-802).

NOTE: Put Foil Wrap (Material No.P05-169) around the pneumatic joints of the OPV.

Subtask 71-00-00-720-086-A ** ON A/C NOT FOR ALL

B. Do the test below:
(1) On maintenance panel 50VU, push then release the ENG/FADEC GND PWR/1(2) pushbutton switch (the ON legend comes on).
(2) On the MCDU, get the SYSTEM REPORT/TEST page (Ref. AMM TASK 31-32-00-860-012).

ACTION	RESULT
1.Push the line key adjacent to the FADEC 1(2) A(B) indication.	The ENGINE 1(2) MAIN MENU page comes into view.
2.Push the line key adjacent to the LRU IDENT indication.	The FADEC 1(2) A(B) LRU IDENT Menu page comes into view.
3.Read the data that come into view on the MCDU (EEC P/N, ENGINE S/N, ENG RATING and N1 CLASS) to make sure that they are the same as those written on the engine identification plates.
4.On the MCDU, push the line key adjacent to the RETURN indication until the CFDS menu page comes into view.
5.Stop the MCDU.

Subtask 71-00-00-720-087-A ** ON A/C NOT FOR ALL

C. Do the Post Engine Replacement test as follows:

NOTE: All steps refer to the replaced engine unless stated otherwise.

(1) Wet motor to do a check of the return to tank valve connections for leakage (Ref. AMM TASK 71-00-00-720-814).

NOTE: The return to tank valve does not open during idle run.

(2) Start both of the engines by automatic start (Ref. AMM TASK 71-00-00-860-823).

NOTE: This is the recommended start method for normal conditions.

(3) Start the engines manually as necessary (Ref. AMM TASK 71-00-00-860-822).
(4) Make sure that all the engine parameters are in the permitted limits (Ref. AMM TASK 71-00-00-910-803).
(5) Let both of the engines become stable for five minutes at MINIMUM IDLE.
(6) Make sure that all of the engine parameters are in the permitted limits (Ref. AMM TASK 71-00-00-910-803).
(7) Do the Test No. 6 - FADEC System - EEC - Idle Test (Ref. AMM TASK 73-21-00-710-807):

NOTE: Test 6 is not necessary if Test 7 was done as part of the set up.

(a) When the engine is running, do as follows:
1 Do a test of the nacelle and wing anti-ice systems:
a Operate the replacement engine and make sure that the nacelle anti-ice system operates correctly (Ref. AMM TASK 30-21-00-710-002).
b Operate the replacement engine and make sure that the wing anti-ice system operates correctly (Ref. AMM TASK 30-11-00-710-001).
(b) When the engine is shutdown, do as follows:
1 Check the engine for oil and fuel leaks (Ref. AMM TASK 71-00-00-720-811).
2 Check the engine for pneumatic leaks (Ref. AMM TASK 71-00-00-790-802).
3 Do an operational test of the thrust reverser system with the MCDU (Ref. AMM TASK 78-31-00-710-805).
(8) Check the engine for leaks (Ref. AMM TASK 71-00-00-720-811).
(9) Do the necessary tests for the replacement engine that was disassembled since the test in a test cell or was not tested in a test cell since removal from the wing as follows:

NOTE: This step is not required if this is a complete serviceable engine that was tested in a test cell and accepted as serviceable or a complete engine known to be serviceable, removed from service as a spare and installed on the aircraft as a replacement.

(a) Do the tests as specified in the test reference table for the parts or components that were repaired or replaced (Ref. AMM TASK 71-00-00-700-806).
(b) Do the power assurance test (Ref. AMM TASK 71-00-00-710-806).
(c) Do the acceleration and deceleration test (Ref. AMM TASK 71-00-00-710-805).
(10) Do a test of the nacelle and wing anti−ice systems as follows:
(a) Operate the replacement engine with the anti−ice system ON and then OFF.
(b) Make sure that the anti−ice system operates satisfactory (TO BE FURNISHED BY AIR-FRAME MFG).
(11) Do an operational test of the thrust reverser (deploy and stow) (TO BE FURNISHED BY AIR-FRAME MFG) (Ref. AMM TASK 78-31-00-710-805).
(12) Let both of the engines become stable for ten minutes at MINIMUM IDLE.
(13) Shutdown both of the engines (Ref. AMM TASK 71-00-00-860-814).
(14) Examine the assembly for foreign objects, damage and correct assembly.
