ENGINE NACELLE
General Description
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. The forward fairing will need to be removed to
gain access to GSE bootstrap interface points. The forward fairing is held in place by 7 quick release latches allowing easy access to GSE hard points for the bootstrap system. The thrust reverser is made in two halves ("C"-Ducts) which are raised open with integral actuators by a hydraulic pump which must be purchased as Ground Support Equipment (GSE). Once the "C"-Ducts are open, an automatic lock
in the actuators holds each "C"-Duct open. GSE actuator locks provide a backup for the locks in the actuators. When removing an engine, the actuators are disconnected and GSE thrust reverser cowl hold-open rods are the only means of holding the "C"-
Ducts open.
With the thrust reverser halves held open, engine removal and installation is accomplished using a "bootstrap" hoisting system.
