Model GA8-TC 320 Description
7.10 ENTRANCE DOORS
A forward opening cockpit door is tted to each side of the aircraft. The door latch is a simple
rotary latch operated by a handle on both the inside and out. These doors also act as emergency
exits.
A forward sliding rear cabin door is provided on the left hand side of the aircraft. The door latch
is located at the rear end of the door, and is a two part operation to unlock. From the inside,
the handle is pulled inwards, then rotated forward where upon the door slides freely. From the
outside, depress the button above the handle with one hand and then rotate the handle with
the other hand, where upon the door begins to slide. For closing, the door is slid closed and the
handle rotated from either inside or outside until it locates into the lock detent.
Opening of the doors in ight is approved in an emergency such as for smoke or fume evacuation
and for special operations in accordance with approved supplements in Section 9. Although
ight handling is not affected with the door open, airspeed should be restricted to a maximum of
approximately 100 KIAS to minimise air loads on the open door.
