LOCATION
ZONE: 147, 148
COMPONENT DESCRIPTION
The Green or Yellow hydraulic motors may be inoperative
provided the Blue SLAT motor to remains operative
(refer to MMEL 27-51-01 A).
If the yellow flap motor fails and then the blue slat
motor, the flaps and slats system will operate on the
green system only.
This will involve a green low pressure and therefore
may lead to an under speed detection by SFCC 1 & 2
which will cause the system to lock.
To prevent such an event, the blue slat motor must be
operational if the aircraft is to be dispatched with
an inoperative yellow flap hydraulic motor.
