Measure the ski jump values at approximately the 9 positions which are shown on Fig. 508A for the right elevator.
 NOTE: During the measurement process, do not put the
____ ski jump tool on any rivets of the elevator or the stabilizer.
 a)  Write down in Table 501, the measurement values for each position.
 NOTE: The ski jump values will be a negative number
____ when the elevator is below the upper surface of the stabilizer. If a value is positive at a position, put a 0 in Table 501 for that position.

 5)  Do these steps again to measure the ski jump values for the left elevator.
 NOTE: You must align the left elevator with the index
____ mark. It is not necessary to adjust the dial indicator of the ski jump tool assembly again.
 6)  Calculate the average ski jump as follows:
 NOTE: The values for the left and right elevator ski jump
____ averages are calculated at the bottom of Table 501.
 (LEFT ELEV SKI JUMP AVG + RIGHT ELEV SKI JUMP AVG) .................................................. = AVG SKI JUMP 2
 7)  Use Table 502 to find the incremental change in the tab position due to the ski jump (SJ).
 NOTE: This value, SJ, is the value which is used in
____ Table 503 and Table 504 to find the Elevator Tab "Xi" Dimension before flight test.

 (i)  While you move the elevator trailing edge down, align the right elevator trailing edge with the index mark within |0.04 inch or less.
 NOTE: Keep the elevators at this position while you do the
____ step to measure the elevator tab position. If the elevator position is changed, you must put the elevator trailing edge at the full up position and do this step again before you continue.
 (j)  Use one of the two methods that follow to adjust the right hand elevator tab pushrods.
 NOTE: The recommended method to use is the four point method
