• Internal Grab Bar: Installed in the upper part of the cargo door opening
to provide mounting structure for the wind deector and as a location to
hold onto while the vertical sliding door is open.
• Vertical Sliding Door: Installed in the cargo door opening to keep wind
from entering the cabin during taxi, takeoff, climb, descent and landing.
The following additional equipment may be installed as an option (not
required) for operations with the cargo doors removed:
• Signal Lights and Switches: To provide a method for the pilot to signal
commands to crew members performing drops from the door.
• Static line attachment: Located on the right interior sidewall across
from the cargo door. This provides a method to perform cargo drops of
supplies with automatic parachute deployment.
• Sill Protector: Installed in the cargo door opening to protect the frame of
the cargo door when performing cargo drops.
• Door Closing Mechanism: Provides a pilot actuated handle which allows
the pilot to close the vertical sliding door.
• Jump Exhaust Stacks: Positions the exhaust plume further away from
the side of the fuselage.
VERTICAL SLIDING DOOR
The original cargo door is replaced by a vertical sliding door made from
transparent polycarbonate panels and aluminum hinges which are guided
in UHMW (plastic) rails. The door is opened by lifting up on the bottom of
the unit and sliding it upward until it reaches its stop. To close the door, pull
down on the bottom of the door until it rests on the oor of the aircraft. If the
aircraft is equipped with an optional door closing mechanism, the pilot may
close the door by pulling the handle located in the cockpit headliner. The
door remains closed by its own weight.
WIND DEFLECTOR
A wind deector is installed just aft of the cargo door opening to minimize
airow buffeting within the cabin with the vertical sliding door open.
INTERNAL GRAB BAR
An internal grab bar is installed just inside the cargo door on the upper left
side of the fuselage. The grab bar is provided as a stabilizing hand hold for
operations with the cargo doors removed.
