3.5.2 CREW ENTRY DOOR
The Crew Entry door is located on the left side of the fuselage and it is embedded in the Large Cargo
Door. The Crew Entry door is outward opening non plug type door with a net opening of 944 mm (24 in)
wide and 1889 mm (48 in) high. The Crew Entry door has two hinges on the fore edge and it is latched by
five shoot bolts which are locked by two latch-locks. A pressure vent door is operated simultaneously
with the latch-locks. The door mechanism is driven by both internal and external handles allowing the
door to be operated from inside or outside of the aircraft. The door is equipped with a hold-open device
that engages the external handle when the door is open. Two microswitches installed on the surround at
shoot bolt locations and one microswitch installed on the door at latch-lock location provide a signal
alerting, if the door is not fully latched and locked.
