LEVELING.
The airplanes are provided with a means for longitudinal and lateral leveling. The airplanes may be leveled
while on jacks, during the weighing procedure while the wheels are on scales, or while the wheels are on the
ground. To level the airplane for purposes of weighing or rigging, the following procedures may be used:
1. To longitudinally level the airplane, partially withdraw the two leveling screws located immediately
below the left front side window. (Refer to Figure 8-1.) Place a level on these screw heads and adjust the jacks
until the level is centered. Should the airplane be either on scales or on the floor, first block the main gear oleos
to full extension; then deflate the nose wheel until the proper position is reached.
2. To laterally level the airplane, place a level across the spar box assembly located under the rear seat.
(Refer to Figure 8-2.) Raise or lower one wing tip by deflating the appropriate tire on the high side of the
airplane or adjust either jack until the bubble of the level is centered.
WEIGHING. (Refer to Figure 8-3.)
The airplane may be weighed by the following procedure:
1. Position a scale and ramp in front of each of the three wheels.
2. Secure the scales from rolling forward and tow the airplane up onto the scales.
3. Remove the ramp so as not to interfere with the scales.
4. If the airplane is to be weighed for weight and balance computations, level the airplane per instructions
given in Paragraph titled Leveling.
