Introduction
This section describes the procedure for establishing the basic empty
weight and moment of the airplane. Sample forms are provided for
reference. Procedures for calculating the weight and moment for
various operations are also provided. A comprehensive list of all
equipment available for this airplane is included at the back of this
section.
It should be noted that specific information regarding the weight, arm,
moment, and installed equipment for this airplane as delivered from
the factory can only be found in the plastic envelope carried in the
back of this handbook.
It is the responsibility of the pilot to ensure that the airplane is loaded
properly.

Airplane Weighing Procedures
A basic empty weight and center of gravity were established for this
airplane when the airplane was weighed just prior to initial delivery.
However, major modifications, loss of records, addition or relocation of
equipment, accomplishment of service bulletins, and weight gain over
time may require re-weighing to keep the basic empty weight and
center of gravity current. The frequency of weighing is determined by
the operator. All changes to the basic empty weight and center of
gravity are the responsibility of the operator. Refer to Section 8 for
specific servicing procedures.
1. Preparation:
a. Inflate tires to recommended operating pressures.
b. Service brake reservoir.
c. Drain fuel system.
d. Service engine oil.
e. Move crew seats to the most forward position.
f. Raise flaps to the fully retracted position.
g. Place all control surfaces in neutral position.
h. Verify equipment installation and location by comparison to
equipment list.
2. Leveling (Figure 6-2):
a. Level longitudinally with a spirit level placed on the pilot door
