longitudinal reading, and the upper limit is
established by adding 0 degrees, 40 minutes to the
longitudinal reading taken in the auxiliary wheel well.
For example, if the longitudinal reading was 1 degree,
35 minutes, the lower limit would be 1 degree,
15 minutes, and the upper limit would be 2 degrees,
15 minutes. Figure 9-48 shows a wing twist check on
an aircraft. The wing clinometer readings must fall
within this range as well as within 0 degree,
12 minutes of each other (right- to left-hand wing
readings). This check, together with the steel tape
measurements taken when the wings are spread, is a
satisfactory check of wing bending and twisting. If
the clinometer readings and tape measurements arc
not within the tolerances specified, the aircraft must
be taken to a depot-level maintenance facility for a
complete inspection and final disposition.
