___________________________________________
 1. General
_______
 (Ref. Fig. 001)
 Three doors close each Main Landing Gear (MLG) bay. These are:
 -
a hydraulically-operated main door

 -
a mechanically-operated hinged-fairing door

 -
a fixed fairing door on the MLG leg.

R  When the MLG retracts, all the doors close. When the MLG extends, the hydraulically operated doors close and the mechanically operated doors stay open.
 A door opening mechanism lets the hydraulically operated doors open on the ground, for access to the MLG bay. A ground door-opening handle operates a bypass valve in the doors hydraulic circuit and releases the doors uplocks.
 A ground lock-sleeve can be installed on each door actuator, to keep it
 open.
