Purpose
The exhaust plug assembly controls the inner edge of the
turbine exhaust flow.
The engine vent system uses a hole at the aft end of the exhaust
plug to vent to ambient air.
See the engine oil chapter for more information about the
engine vent system. (CHAPTER 79)
General
The exhaust plug assembly has these major components:
* Forward plug
* Aft plug.
Bolts attach the aft plug to the forward plug. Bolts attach the
forward plug to the engine turbine exhaust case.
Location
The exhaust plug is on the aft end of the engine turbine case.
You must do these tasks to get access to the exhaust plug bolts:
* Open the fan cowls to the full open position
* Open the thrust reverser cowls (halves)
* Remove the exhaust nozzle.
Training Information Point
You must remove the exhaust nozzle and the aft plug before
you remove the forward plug.
An alignment pin on the forward plug, near the 12:00 position,
helps you align the forward plug during installation.
The aft plug has a small notch near the 12:00 position. This
notch helps you align the aft plug during installation.
The leading edge flaps can extend and damage a T/Rs half
when the half is in the open (maintenance) position. Follow the
AMM procedures to prevent leading edge flaps operation.
T/R halves in the open position can also damage the leading
edge flaps if you deploy the T/R.
WARNING: DO THE DEACTIVATION PROCEDURE TO
PREVENT THE OPERATION OF THE THRUST
REVERSERS. THE ACCIDENTAL OPERATION OF
THE THRUST REVERSER CAN CAUSE INJURIES
TO PERSONS AND DAMAGE TO EQUIPMENT.

General
The thrust reverser (T/R) system has these subsystems:
* Thrust reverser
* Control
* Indicating.
Thrust Reverser System
The T/R system controls the direction of engine fan air exhaust
for forward and reverse thrust.
Reverse thrust helps decrease the speed of the airplane after
landing or during a rejected take off (RTO).
T/R Control System
The T/R control system controls electrical and hydraulic power
to the T/R system.
T/R Indicating System
The T/R indicating system supplies T/R system and T/R control
system indication in the flight compartment.

General
The thrust reverser (T/R) system has these subsystems:
* Thrust reverser system
* Thrust reverser control system
* Thrust reverser indicating system.
Thrust Reverser System
The T/R system changes the direction of the fan air exhaust to
help decrease the speed of the airplane after landing or during
a rejected takeoff (RTO).
The T/R system has two thrust reversers. T/R 1 is the thrust
