9.5-6 WEIGHT AND BALANCE
The actual weight and balance of the aircraft must be calculated for all
ights, including the takeoff, in ight operations, and landing.
An aft transient CG limit of 45% MAC is permitted while in the cargo drop
condition only (75 KIAS, Flaps 20°, Maximum Bank Angle 10°, Straight and
Unaccelerated Flight).

9.5-7 AIRPLANE SYSTEMS & DESCRIPTION
INTRODUCTION
The Cargo Doors Removed Kit is designed to improve passenger comfort
and facilitate passenger-to-pilot communications during special purpose
operations such as emergency air drops and aerial photography. The kit
consists of the following required equipment:
• Wind Deector: Installed in the aft part of the cargo door opening
to minimize airow buffeting within the cabin with the cargo doors
removed.
CARGO DROP OPERATIONS CG ENVELOPE
WARNING: The aft transient limit of 45.00% MAC is ONLY allowed while
the airplane is in the cargo drop condition (75 KIAS, 20° Flaps, Maximum
Bank Angle of 10°, level and coordinated ight). Flight tests have been
accomplished up to this transient CG limit to ensure safe operation of the
aircraft in a limited ight envelope (cargo drop condition only). DO NOT
exceed the aft transient limit of 84.02 inches aft of datum (45.00% MAC)
as the aircraft will become unstable and loss of control may occur. The
extended 45% CG limit for cargo drop operations applies only at weights of
6750 lb and below. Cargo drop operations at weights above 6750 lb must
not exceed the 40% CG limit.
