 NOTE: One turn of the ballnut is equivalent to 0.625 inch
____ (15.87 mm) of axial movement along the ballscrew.
 3)  If the above condition is not correct, adjust the turnbuckles on cables SLA and SLB until the condition is correct.
 4)  Move the horizontal stabilizer in the airplane nose down direction (stabilizer leading edge up) until it is stopped by the travel limit shutoff.
