1. GENERAL
All crew members should receive adequate train-
ing in the handling of emergency exits and evac-
uation procedures.
WARNING
The aircraft is provided with five emergency exits;
− Main door (1)
− Forward right exit (1)
− Overwing exits (2)
− Cockpit escape hatch (1)
The aircraft is provided with one Cargo door which
is not considered as an emergency exit and normal-
ly operated from outside. On some aircraft the Car-
go door may be operated also from inside, by in-
serting a handle into the door locking mechanism.

Fig. 1 Emergency exits
When a ground air conditioning unit is supplying air
to the cabin with the doors closed, the cabin may
become slightly pressurized (depending on the ca-
pacity of the unit). This may require an extra effort
to open the emergency exits and to unlock the main
door. Leaving the cockpit ground communication
hatch slightly open would alleviate the situation.
NOTE
2. MAIN DOOR
If the main door handle has been inadvertently
moved to the closed position with the door open, a
latch in the middle of the door (inside) has to be
pressed before the handle can be returned to open.
The latch is a plastic ”roller” about 5 cm long.
NOTE
General
The main door, located on the forward left side fu-
selage, is primarily intended for embarkation/ dis-
embarkation. It is also used as an emergency exit
(type I).
The main door is of ”semi − plug” type, held in posi-
tion by door stops, guided pins and doorway sup-
port fittings.
When rotating the door handle from closed posi-
tion,the door moves slightly upwards to a position
where the door stops and guide pins are clear of
the doorway support fittings. The door can then be
swung outwards to the fully open position.
Friction loads between the door and the doorway,
induced by cabin pressurization, will prevent door
opening until cabin differential pressure has been
reduced to a low value.
When opened fully, a spring − loaded hook on top of
the main door hinge will engage an external fuse-
lage bracket, retaining the door in the fully open
position. To close the door, the hook is released by
either of the two door lock release knobs, accessi-
ble from the cabin and the ground, respectively.
