FAN COWLING
Identification (1.A.a)
The CFM56-7 engine fan cowling and thrust reverser segments are hinged to the strut. To remove or install an engine, the fan cowls need to be removed to provide access to the forward engine ground handling points. The fan cowls are held in the open position by integral hold-open rods for engine maintenance when the engine is installed on the strut.

FAN COWL PANEL REMOVAL (CONT.) SLING METHOD
Use the hoist and sling to open and hold the fan cowl panel.
Release the quick-release pin with the button on the end and remove the pin. Install the drift pin from the sling kit at the hinge. Continue till the all pins are removed, then remove all temporary pins.
MANUAL METHOD
Using 3-4 people manually remove the 96 pound fan cowl panel.
Note: Re-install lock pins in strut holes after the removal of the fan cowl panels to avoid damage to the lanyards during removal of the engine.

THRUST REVERSER ACTUATOR TOOLING
Identification (1.A.a)
The thrust reverser actuator tooling is a hand pump and safety equipment used on the thrust reverser actuator.
Purpose (2.B.b)
The purpose of the thrust reverser actuator tooling is to open the thrust reverser by a hand pump , which uses engine oil. Using this system provides a backup safety feature inside the actuator that lowers slowly the thrust reverser in 11.5 seconds. The actuator when fully opened holds the thrust reverser in the open position by a locking collar another safety feature. The additional safety feature is the u- channel tool with two quick disconnect pins that prevents the thrust reverser from closing until them are removed.

THRUST REVERSER HOLD OPEN TOOLING
Identification (1.A.a)
The thrust reverser is made in two halves ("C"-Ducts) which are raised open with integral actuators by a hydraulic pump. Once the "C"-Ducts are open, an automatic lock in the actuators holds each "C"-Duct open.
The thrust revers actuator locks provide a backup for the locks in the actuators. When removing an engine, the actuators are disconnected and thrust reverser cowl holdopen rods are the only means of holding the "C"-Ducts open.
