General
The turbine exhaust system uses a nozzle and a plug to control
the direction of the turbine exhaust gases.
Components
These are the turbine exhaust system components:
* Plug
* Nozzle.
Physical Description
The exhaust nozzle controls the outer edge of the turbine
exhaust flow. The nozzle attaches to the engine turbine case.
The exhaust plug controls the inner edge of the turbine exhaust
flow. The plug attaches to the engine turbine case.
The plug and the nozzle are made of nickel alloy.

Purpose
The exhaust nozzle assembly controls the outer edge of the
turbine exhaust flow. The aft part also controls the inner edge of
the fan air exhaust flow.
General
The exhaust nozzle assembly has these components:
* Inner sleeve
* Labyrinth seals
* Fairing
* Fences.
Bolts attach the inner sleeve to the turbine exhaust case.
The exhaust nozzle uses labyrinth seals to contain fire. Bolts
attach the seals to the inner sleeve.
The fairing helps smooth the inner edge of the fan air exhaust
flow. Rivets attach the fairing to the inner sleeve.
The nozzle fences control the airflow of the fan air exhaust over
the nozzle assembly.
Location
The exhaust nozzle assembly is on the aft end of the engine.
You open the fan cowls and thrust reverser halves to get
access.
Training Information Point
An alignment pin on the inner sleeve, near the 12:00 position,
helps you align the nozzle assembly during installation.
The leading edge flaps can extend and damage a T/R 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.
