Center of Gravity The center of gravity range is between 22.5 and 27.5 percent MAC
(CG) Range (stations 296.96 and 303.54).
Datum Reference Datum is 149 inches forward of jig point located in nose wheel well. The jig
point is located by hanging a plumb bob from the small hole drilled in the beam on the
aft bulkhead of the nose wheel well.
Mean Aerodynamic Chord The leading edge of the MAC is at Station 267.33.
(MAC) The length of the MAC is 131.67 inches.
Leveling Means Longitudinal leveling is determined by use of plumb bob hung from small hole drilled
Longitudinal in the shelf in either main wheel well.
Lateral Lateral leveling is determined by use of leveling device on leveling brackets on nose
wheel well bulkhead at station 150.

loading instructions when necessary, must be in each aircraft at the time of original certification and at
all times thereafter.
b. Refer to FAA Approved Airplane Flight Manual, Sections 7 and 8, for weight and balance and weighing
instructions.
c. The certificated empty weight must include unusable fuel of 37 gallons (222 lbs. at 300.6 inches (arm)),
and unusable oil of 4 gallons (30 lbs. at 262 inches (arm)).
NOTE 2. Required placards are listed in Resorts International Drawing RI100F2011.
