2-13. WEIGHING. (Refer to Figure 2-7.) The airplane may be weighed by the following procedure:
a. Position a scale and ramp in front of each of the three wheels.
b. Secure the scales from rolling forward and tow the airplane up onto the scales. (Refer to Paragraph 2-
18.)
c. Remove the ramp so as not to interfere with the scales.
d. If the airplane is to be weighed for weight and balance computations, level the airplane per instructions
given in Paragraph 2-14.
2-14. 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:
a. To longitudinally level the airplane, partially withdraw the two leveling screws located immediately
below the left front side window. (Refer to Figure 2-8.) Place a level on these screws 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.
b. To laterally level the airplane, place a level across the spar box assembly located under the rear seat.
(Refer to Figure 2-9.) 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.
