4. Procedure
Subtask 71-00-00-860-182-A ** ON A/C NOT FOR ALL

A. Shutdown of the Engine for an Emergency
(1) Quickly and immediately move the Engine 1 or Engine 2 thrust lever to the IDLE position.
(2) If conditions permit, operate the engine at IDLE for ten minutes before you shut down the engine. Otherwise, go to Step 4.A.(3).

NOTE: An emergency shutdown is a shutdown from power levels higher than IDLE. Use this emergency shutdown procedure only for emergency conditions which do not let you use a normal shutdown procedure.

NOTE: A hot shutdown is considered to be shutting down the engine that was operated above 70% N1 for more than one minute in preceding 20 minutes of operation.

(3) On the center pedestal, on ENG panel 115VU:
(a) Set the ENG/MASTER 1(2) control switch to OFF.

NOTE: This will stop the fuel supply to the engine.

(4) If the engine has a tail pipe fire, dry-motor the engine with the starter when N2 is less than 20% on the engine display panel, until the fire goes out. Do not obey the starter time limits if the engine has a tailpipe fire (Ref. AMM TASK 71-00-00-860-817).
(5) If the engine shutdown was a hot shutdown, do the steps that follow:
(a) In less than five minutes after the emergency shutdown (or when N2 is less than 20%), dry-motor the engine as follows (Ref. AMM TASK 71-00-00-860-817).
1 Dry motor the engine but do not exceed the extended starter duty cycle of 15 minutes maximum continuous cranking.
(6) Set the EXT LT/BEACON switch to OFF position.
(7) Maintenance action is due.
(8) Examine the assembly for foreign objects, damage and correct assembly.
(9) Installation of protection covers

CAUTION: INSTALL PROTECTION COVERS ON ALL THE OPENINGS IMMEDIATELY TO PREVENT DAMAGE TO THE ENGINE.

(a) Make sure that you install COVER - PROTECTION as necessary to prevent damage to the engine.

(3) De-energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-862-002).
